Precast Concrete Lifting Design

The selection of lifting devices should be carefully made dependant on the type of lift or lifts that the unit will
be subject to once manufactured. It is vitally important to ensure both safe lifting and that no damage to the
concrete occurs. When assessing the lifting of a unit the following factors must be considered.

The Weight of the Unit
The dead weight of a normal precast unit should be calculated using a concrete density of 2500kN/m2. The
theoretical weight can be calculated either mathematically via the dimensions of the unit or through design
packages. The adhesion to the mould must also be included in the calculation of forces dependant on the type
of mould that the unit is cast in. The following can be used as a guide:

Oiled steel mould = 1kN/m2
Varnished timber mould = 2kn/m2
Rough timber mould = 3kn/m2
The value of adhesion to the mould is calculated by multiplying the area of the concrete in contact with the
mould by the adhesion factor = Area x Mould Adhesion Factor
Double T Beam should be calculated using 2 x deadweight and Coffered units should be 4 x deadweight.

Dynamic Loads
These should be calculated in most lifts of precast units, they are controlled by both the velocity and quality
of lifting equipment and the terrain being transported across.
The following factors should be used:
Demoulding = x 1.1
Turning = x 1.3
Site Transportation = x 1.5 (With a stationary crane)
Site Transportation = x 1.65 (Over even ground)

These are based on using overhead or static cranes at speeds of <=90m/min. For rough ground or when the site
installation details are not known, always use a factor of Dynamic Load ≥ x 2.
The true mass of a precast unit for anchor specification is worked out as follows:
(Demoulding) Mass = (Deadweight +Adhesion Factor) x Dynamic Load
(Transportation) Mass = Deadweight x Dynamic Load

Sling Angle
The angle is dependant on the length of chains / cables that are used to lift the unit. The shorter the chains
the greater the tensile load becomes on each anchor point. The following table show the factors by which the
pull factor should be calculated.

Calculation of Anchor Loads
(1) 2No. Load
Bearing Anchors
It is imperative to ensure that the load is distributed as evenly as possible
when deciding on the number of anchors and lift design.
z z

Thin walled panels and beams should be lifted and turned with two anchors
either with angled chains (1) or a spreader beam (2). This ensures even
load distribution across both anchors providing the anchors are set out
symmetrically either side of the centre of gravity. Please ensure that for
turning units that the correct extra reinforcement is observed.

For slab type units it is always advisable to use four anchors and a spreader
z
beam (3) to ensure even weight distribution. It is not possible to calculate
anchor loads for four anchors in panels as the exact distribution of load z
cannot be guaranteed (4) . Where the unit necessitates such a lift it is
essential to use an equalising device (5) that will distribute loads evenly
across all four anchors. The use of such a system must not only be available (2) 2No. Load
at all areas that the unit is lifted, but also used only by trained and Bearing Anchors
experienced persons. If any details of any part of the lift is not be available
then it should be taken that two anchors will be load bearing.
z β
A three point lift as show in (6) will always provide an even distribution of

load providing the anchors are spaced evenly and correctly around the z
centre of gravity. z

All demoulding should take place with a minimum concrete strength of (3) 4No. Load
15N/mm2 and ensuring that any load reduction factors are taken into Bearing Anchors
account. The safe working loads of all anchors are a minimum of three
times and two times for the concrete.

Capstan Transport Anchor System
The Capstan Transport Anchor system is a simple and effective system for lifting most types of precast concrete
unit. The anchors are forged from high grade steel and, provided the anchor is specified and installed
correctly, provides safe and secure lifting, turning and transportation of units. Anchors are available in black,
zinc plated, galvanised, 304 and 316 stainless steel
Each anchor is stamped on the head with the manufacturers identification and maximum load rating of the
anchor. Anchors are tested to a safety factor of at least three times their safe working load and 2.5 times
concrete failure when installed to the guidelines that follow. Lifting Shackles are proof loaded to twice their
safe working load and are supplied with a test certificate that is valid for six months from date of purchase.
Capstan Anchors are designed for demoulding, transport and site fixing. They should not be used for repeated
lifting applications.

Anchor Use and Specification Considerations
The LFS range of Capstan Transport Anchors are a simple and effective system for lifting most types of precast
concrete units. The anchors are manufactured from high grade steel and, provided the anchor is specified and
installed correctly, provides safe and secure lifting.
The anchors are designed as a method of demoulding, transportation and installation of precast units and
should not be used for repeated lifting. All anchors are tested by an independent institution to at least three
times safe working load and are supplied with batch numbers and certification on request. All shackles are
individually proof loaded to twice safe working load and supplied complete with certification on delivery. All
load table data is based upon a safety factor of 2.5 to 1 against concrete failure.
Anchor Operation
The Capstan Transport Anchor works by the distribution of load into the concrete via the tapered foot as shown
below, this provides high load values with short embedments in the concrete. The forces can even be
transferred into thin walled panels and safely lifted with the correct reinforcement.

It is essential to specify the correct length of anchor relevant to
Load Direction
the unit being lifted and the compressive strength of the
concrete at the time of lifting. This is a very important
consideration as reduced anchor loadings are experienced in low
strengths .
Installation
The anchors are installed in the formwork using one of a variety
of recess formers. These hold the anchors securely during
concrete pouring and create a void in which the shackle fits
after removal and once the concrete has cured. The anchor and Load transfers into the concrete in a cone
the recess will only accept the corresponding shackle rendering pattern and will breakout in this manner if
mismatching load groups impossible. overloaded

The anchors are available in various lengths for use dependant on the application required. In general, longer
anchors are to be used in thin panels or low strengths whereas short anchors are best in slabs and stronger
concrete.
It is essential that consideration is taken to ensure that the anchors are equally positioned around the centre of
gravity and that loads are distributed evenly between each anchor.

Installation Instructions for Panels and Beams
For vertical lifting of panels and beams the minimum edge distance required is as follows:
Edge Distance F = (Anchor Length A + Recess Depth E) x 3
These dimensions assume that the concrete is un-reinforced. Smaller edge distances are possible with suitable
reinforcement.
Walls and beams that contain only standard reinforcement shown overleaf should only be lifted at angles of
β ≤ 30o. If the loading on the anchors is reduced then the amount of reinforcement can be reduced.

Capstan Eye Anchor
The Capstan Eye Anchor is for use when the transfer of load is not possible through the foot of a standard
anchor. This is usually for thin reinforced units or lightweight concrete. Reduced bond stress may need to be
considered for lightweight concrete.
The re-bar tail must be in close contact to the bottom of the hole to prevent concrete breakout when lifting.

Capstan Plate Anchor
The Capstan Plate Anchor is designed for reinforced concrete slabs too thin for a standard Capstan Anchor
which are lifted at right angles to its greatest dimension and for de-moulding panels.
The minimum panel thickness (J) is determined by the unit design by combining the anchor length, anchor head
recess and the specified cover. It is essential that not only the cover is observed but that the concrete can flow
freely under the base of the anchor to ensure corrosion resistance.

Curved Capstan Transport Anchor
The Curved Capstan Transport Anchor is specifically designed for lifting, pitching and transporting sandwich
panels.
After installing the anchor head is positioned in the centroidal axis of the panel with the foot being central in
the load bearing layer which ensures a proper load transference. Spalling of the concrete during erection and
lifting is avoided with Curved Capstan Transport Anchors. A tilting table should be used to pitch units if
produced with only a front layer on top. Using connector pins close to the anchor is advisable.
These anchors should be used in conjunction with a spreader beam.

Capstan Rod Anchor
The Capstan Rod Anchor is designed to pitch and lift very thin wall panels, reinforced girders or similar types of
unit as well as masonry wall units.
The anchor consists of a ribbed steel bar with a forged Capstan lifting head. The load is transferred into the
concrete by the ribs of the steel bar.
For special fabrications the bar can be bent in an offset manner to fit units such as sandwich panels.

Double Head Capstan Transport Anchor
The Double Head Capstan Transport Anchor has been specifically developed for use in pipe production where
anchor installation is automated. This permits high volume production by eliminating the manual operation of
fixing anchors.
The second head of the anchor assists accurate positioning and ensures perpendicular installation as it sits
tightly in the hollow of the former.
This feature also benefits the production of high volume flooring where large amounts of anchors are installed
on a regular basis. The rubber former is hard wearing and has a thread which allows quick removal and cleaning
with no requirement to remove excess concrete in the void. This anchor is lifted with the same shackle as
standard anchors.

Recess Formers
There are steel, magnetic and rubber formers available for Double Head Anchors. The steel formers are
designed for welding to the mould and have a magnetic insert to keep the anchor in place when casting.
Magnetic formers are also steel and have magnets in the base to securely attach to the formwork.
Rubber formers work in the same manner but have a metric screw thread in the base to attach through wooden
formwork for quick removal from cured concrete with a floating application.

Double Head Capstan Transport Anchor
Use with Hollowcore Flooring Manufacture
The Double Head Capstan Transport Anchor is a very effective method of demoulding, lifting and installation of
most types of Hollowcore flooring panels.
The anchors are installed in extruded or slip formed Hollowcore by collapsing the cores at the required lifting
points and back filling with a suitably wet mix of the same concrete to the top of the panel. Larger sizes of
cores may require the use of a Slab Cap or semi-dry mix inside the core either side of the lifting point. The
concrete should be compacted well without damaging the webs, taking care that the recess is completely
filled.
The anchor should be worked down in the poured concrete until the former is flush with the top of the panel
ensuring no possibility of air gaps and trowel around the former for a neat finish.
It is recommended that, where possible, demoulding Hollowcore should be carried out using clamps or ensuring
that the concrete is sufficiently cured to support the load required for the lift.
With most Hollowcore applications, the edge distances that are achievable are less than would be expected for
obtaining full lifting loads in unreinforced concrete. However, as the deadweight of the units are greatly
reduced by the cores or polystyrene, the loads on each anchor is reduced resulting in effective lifting with
relatively small edge distances.

Because there are large variations in the concrete mixes, reinforcement
strand patterns and lifting intentions, it is imperative to ensure that the
anchor and installation is correct for each application. LFS offer a
complete design and technical support service for customers wishing to
implement the Double Head Anchor system into their production. This
service includes load calculations, anchor specification, training and an
on-site service to test the load capabilities in concrete panels. Our test
unit has a 25.0t capacity for both proof and destructive loading of
anchors. This testing includes both initial set up and periodically
arranged visits to monitor the continuity of achievable loads. This test-
ing is backed up by a full report of results and technical support for
customers working in partnership with LFS.

Lifting with Double Head Anchors
The Double Head Anchor uses the same shackle as standard Capstan Anchors. LFS recommend that clients using
this system should fully convey the permitted lifting design to their customers, for example, many installations
are intended for final positioning only. It is imperative that the installation teams are fully aware of such
arrangements.

When all site lifting requires use of Double Head
Anchors, the use of a Safety Lifting Rig is
recommended. The rig is constructed as shown
opposite and is designed to offer complete
security with safety chains under the panels and
exact load distribution between each anchor by
use of an equalising plate.
Safety Lifting Rigs are designed for panels up to
10.0t and can be manufactured specific to
customer requirements. These are supplied with
test certificates and are available for both sale
and hire at daily and weekly rates.
Please contact LFS for all sale, hire and technical
information.

Capstan Lifting Shackles
The Capstan Shackle is the attachment used for lifting, turning and transportation of concrete units with the
corresponding anchors cast in. This is a manually operated device which is available in 1.3t—32.0t load groups.
Each shackle is proof loaded to twice safe working load at a recognised independent test institution and
supplied certified and index numbered for traceability when supplied new. All health and safety regulations
and suitable risk assessments should be observed when using LFS lifting shackles and site lifting equipment.

Using Capstan Lifting Shackles

Engaging
Select the correct shackle and place the head opening over the anchor
and lower the weighted lip down onto the concrete as show in Fig. 1.
The shackle will now be ready for use.

Lifting
Once the shackle is engaged the unit can be lifted. The direction of lip
must always be in the direction of the lift as this locks the shackle under
load. The shackle is suitable for axial / angled lifting, turning, pitching
and swivelling of units providing the anchors have been suitably
reinforced. Please observe the maximum lifting angles per the design
which should be supplied by the manufacturer or engineer.

Releasing
Once the lift has been completed and the load has been removed the Lift Direction
shackle can be released by moving the lip towards the handle. Always
ensure that the shackle is clear of the recess before withdrawing the Lift Direction
crane. Fig

Capstan Recess Formers
The Capstan Anchor must be installed in the unit using the correct former for the anchor and application. This
will provide quick and secure installation and form a recess for the shackle. Only the correct former will fit the
anchor and the load group is marked on each one. The former can be used by floating in the concrete or by
bolting through the formwork or by magnets. The formers are available in recyclable rubber and steel in load
groups from 1.3t to 32.0t.

Rubber Formers
The rubber former is resistant to oil and retains its shape in temperatures up to 120 oC. The former is reusable
many times if correctly used and cleaned after each use. Mould oil should be applied to the former before the
anchor is inserted.
Short sided formers are also available and are for use when lifting thin panels.

Floated Installation
With this application the concrete is poured first and the anchor is installed once the fill level has been
achieved. The anchor is inserted into the concrete until the bottom of the former is touching the concrete
which should then be vibrated until the top is flush with the concrete. At its final position the anchor much be
perpendicular to the base of formwork. It is advisable to use a fixing screw and a wooden block to ensure the
former is tightly shut to prevent any concrete ingress.

Removal of Former
When the concrete has cured the former is simple to remove. If a fixing screw has been used, remove this first
and, with two pieces of reinforcement bar, use a scissors action to release the former from around the anchor
and lift the former clear. If there is any excess concrete in the recess this should be removed before lifting.

Installation with Fixing Screw
When installing through wooden formwork a fixing screw or nut is required. If the
sides of formwork can be removed in a horizontal direction then a fixing screw
can be used. When this is not possible then a separate fixing nut and screw is
required. These are available in all load groups.


21

Steel Recess Formers
The Capstan Anchor can be installed in metal formwork by the use of a steel formers.
These is used where the lifting anchors are not accessible when casting. They are
available in load groups from 1.3t to 20.0t. All steel formers are zinc plated for
corrosion resistance.
Using Steel Formers
The former is first attached to the mould by either its thread or by welding. The
anchor is then placed in the centre of the former and the rubber sleeve put around
the shank and pushed into the void, holding it tightly in position. The former and
sleeve should be coated in mould oil before casting. When the unit is struck the
former remains on the mould with the anchor and sleeve coming away with the unit.
The sleeve should then be removed and cleaned for reuse.

When installing using steel formers, particularly when the anchors are horizontal to the formwork, provisions
should be made to ensure it remains fixed during pouring. This can be done by tying the anchor to the form-
work or by using spacers.
Magnetic Formers
The steel formers are also available with magnets installed in the base to allow the attachment of anchors at
any required point in a steel mould. These have either three or six magnets in the base and should be chosen
dependant on the adhesion required when casting. Larger units with a heavy concrete flow should use the
higher adhesion. The rubber sleeve should be used in the same manner as standard steel formers.

Installation Instructions for Precast Units

Placement of Utility Anchors
This can vary dependant on the structural shape of the units
and the manufactures or engineer’s preferences. Utility
Anchors are not designed for thin edge applications. Always
ensure that the minimum edge distances are maintained and
that lifting design takes into consideration the minimum
strengths as noted in the capacity chart along with any other
dynamic forces.
It is recommended that the formers should always be placed in
line with the load direction of lifting chains.

Typical Installations
Wet Setting
1) Assemble the anchor, former and
either a Fixing Screw or Wet

For turning or erecting units through 90º as detailed below, only half the weight of the unit is being lifted and
therefore there is no reduction in the safe working load of the anchor and the same permissible loads and
standard sling angle reduction factors apply. However, for lifting at these angles the permissible load per
anchor is half the axial load rating. Sling angle factors apply to the chains in the same manner as axial lifting.

Wavy Tail Lifting Anchors
Wavy Tail Anchors are a quick to install and versatile anchor for lifting most types of precast units. The
anchor can be used to lift at compressive strengths of 15N/mm2 and above without any further reinforcement
providing the unit has sufficient BSt 500 mesh or re-bar cage befitting the unit as specified by the design
engineer. The body of the insert is available in high grade carbon steel with either yellow zinc plated for Rd
threads or white zinc plated for metric threads. They are available with 12mm to 52mm threads with the re-
bar tail swaged to the socket. Stainless Steel sockets and re-bar tails are available to special order.

All installation instructions are based on a 2:1 concrete safety factor at a strength of 15N/mm2 and 3:1 for
steel inserts and are tested by a recognised institution.
Wavy Tails can be used in conjunction with Plastic Nailing Plates or Magnetic Holding Plates to provide a
10mm recess that can be made good on site. Plastic Stopper Caps are also available to protect threads from
weathering. There are two standard lengths of rebar tail available, both anchors are designed for axial and
angled lifts of β ≤ 60º (1) and the long anchors also permit the turning of units with the correct
reinforcement. Please contact LFS with any technical queries

LFS Stab Anchor
LFS Stab Anchors are especially suitable for installation in slender concrete units with thin walls such as
garages, transformer stations, shaft rings etc. The anchor can be used to lift at compressive strengths of
15N/mm2 and above without any further reinforcement providing the unit has a sufficient BSt500 mesh
or re-bar cage befitting the unit as specified by the design engineer. The body of the insert is available
in either yellow zinc plated for Rd threads or clear zinc plated for metric threads and is supplied with
12mm to 52mm threads with the re-bar tail swaged to the socket. Stainless Steel sockets and re-bar
tails are available to special order. All installation instructions are based on a 2:1 concrete safety factor
at a strength of 15N/mm2 and 3:1 for steel inserts and are tested for by a recognised institution.
Stab Anchors can be used in conjunction with Plastic Nailing Plates or Magnetic Holding Plates to provide
a 10mm recess that can be made good on site. Plastic Stopper Caps are also available to protect threads
from weathering. The standard length of rebar tails available are detailed below, however special
lengths and bent bars are available on request. The anchors designed are for axial and angled lifts of
β ≤ 60º (1) and the turning of units with the correct reinforcement.

The minimum panel thickness is determined by taking the conditions of use as a basis, according to DN 0145
Table 10, line 1 and section 13.2. For other applications and environmental conditions, the concrete cover
must be increased and hence enlarging the panel thickness as shown in Fig. 3 (D). When making a recessed
installation with the Plastic or Magnetic Nailing Plate (4) the minimum panel thickness must be increased by
the depth of the recess.
Important – Crossed bars (2) are required for M/Rd 24 threads and above and reinforcement should be wired
either side of the socket to ensure close contact with the plate for all sizes.

Instructions For Use
Prior to each loop being used to lift, it should be threaded fully into the socket until it
bottoms out, this should be at least one and a half times the thread diameter. If dirt or
ingress prevent this then the threads should be cleaned and the loop re-inserted.

Loops can be used to lift at angles of up to β = 90°. Combination Lifting Loop or Swivel
Eye should be used for pitching and turning applications. Using Lifting Loops at angles
greater than β = 90° can cause damage at the ferrule and excess strain on the wires
causing breakages.

All loops must be replaced at the first sign of any broken strands, wire breakage,
crushing, kinking, thread damage, corrosion, sharp bends or any other damage that
could affect the strength or operation of the item. Lifting Loops should be assessed by a
competent person every six months and re-tested annually.

Polypropylene Cast In Loops
LFS Polypropylene Cast In Loops are a cost effective method of lifting lightweight concrete units and provide a
crane hook attachment that can be cut off once used.

Product Details
A
These are produced from polypropylene rope with a swaged aluminium
ferrule to create a loop which is individually marked with the
appropriate load rating. These are designed for use for de-moulding,
transportation and fixing only and should not be used more than once
B
such cycle.
The loops are available in load ratings from 150kg to 1200kg and should
be selected according to the lifting design considerations detailed in
pages one and two of this catalogue.
These items can be used with concrete strengths above 15N/mm2 for
axial or angled lifts and for pitching at 20N/mm2 and above. These have
the advantage that the rope does not corrode and stain the concrete.

Installation
Cast In Loops should be installed in the direction of the load with the ferrule in the opposite direction. They
should be positioned around the centre of gravity in a manner that will give a balanced load making sure that
the minimum dimensions are observed as set out in the table below. It may be necessary to use reinforcement
bar for thin units and should be looped as shown below.
When lifting it is essential that the curvature of crane hook is at least the diameter of the loop.

Cast-In Concrete Lifting Loops

Cast-In Concrete Lifting Loops are a cost effective method of lifting many types of precast
concrete units quickly and safely. They provide a quick installation when casting and can
easily be cut off once in position and concealed. However, it should be noted that the
remaining ends can rust and hence stain if not properly concealed.
Providing the following reinforcement details are observed, no further reinforcement is
required under normal circumstances. For any angles greater than β =60º, please contact
Lifting and Fixing Solutions Ltd. The sling angle reduction factors do not apply to Cast-In
Loops. All installation instructions are based on a 2.5:1 concrete safety factor at a
strength of 15N/mm2 and 3:1 for wire rope and are tested for by a recognised institution.
The Loops are manufactured from galvanised steel wire with identification tags showing
the manufactures name and load rating. This product is not designed for repeated use and
should only be used for lifting from factory to site and final installation.
Loops should be selected correctly dependant on the size of the concrete unit, taking all
lifting factors into account. Please contact Lifting and Fixing Solutions Ltd should
calculations be required.
Loops should be installed in the lift direction as follows. The swage should in opposites to
the load with the exposed portion the correct height and the identification tag clear of the
poured concrete. When setting the loops there should be 1/3 of the loop remaining proud
of the concrete. Anchors are also available in higher capacities up to 99.0t on request.

Spread Anchor Lifting System
The LFS range of Spread Anchors are a simple and effective system for lifting most types of precast concrete
units. The anchors are manufactured from high grade steel and, providing the anchor is specified and installed
correctly, it provides safe and secure lifting.
Anchor Selection
The following anchors are available:

Spread Anchors
The most versatile of the anchors and is suitable for lifting most types of beams, wall panels
and slabs. The second hole provides the option to use extra reinforcement where required.
These are available in safe working loads from 0.7t to 26.0t

Two Hole Anchors
Two Hole Anchors are suitable for use where load distribution is not possible through the foot
of a spread anchor and is done so by use of a reinforcement bar tail. They are particularly
useful in thin wall panels and trusses or where concrete strength is low. These are available
in safe working loads from 0.7t to 22.0t

Erection / Unilateral Erection Anchors
These anchors are specifically designed for pitching and turning concrete units. They have
a specially designed head which takes the load rather than the concrete which prevents
spalling and is notched to easily install the extra reinforcement required for pitching. They
are particularly useful for turning thin walled units and are available in safe working loads
from 1.4t to 22.0t

Plate Anchors
These anchors are used for thin slabs and reinforcement is essential. They are available in
safe working loads from 1.4t to 10.0t.

Flat Foot Anchors
These anchors similar in use to the Plate Anchor. They are used for thin slabs and
reinforcement is essential. They are available in safe working loads from 1.4t to 22.0t.

Universal Anchor
These are for light duty applications and combine the benefits of Two Hole, Erection and
Spread Anchors. They are available in 1.25t only and use a smaller Ring Clutch specific to this
load group. They are suitable for small precast units or where a small recess is required.

Sandwich Panel Anchor
These anchors are specifically designed for sandwich panel manufacture. When installed the
anchor head is close to the unit’s centre of gravity allowing it to be lifted in a straight and
upright position. These are available in safe working loads from 2.5t to 17.0t

Spread Anchor Accessories

Ring Clutches
Ring Clutches are a manually operated coupler available in various
load groups for use with LFS Spread Anchors and are compatible with
the Frimeda System. The head of the clutch includes a locking pin
which fastens around the lifting hole of the anchor when installed in
the recess of the concrete unit. The Ring Clutch is coupled to a
corresponding Spread Anchor for the safe lifting laterally, turning or
swivelling of precast concrete units. All LFS Ring Clutches are
individually tested and certified by an approved institution. Ring
Clutches are available in 2.5t, 5.0t, 10.0t and 20.0t load groups with
both solid handles and rope attachments.

the installed anchor and place in the recess as shown in Fig. 1. This can be
found stamped on the head and the shackle. Only the correct clutch will fit
the anchor.
Engaging
The clutch is prepared for lifting by locking the bolt through the anchor by
moving the handle away from the direction of lift as shown in Fig.2. If correctly
installed the clutch should be free to move in any direction and the unit can be Fig. 2
de-moulded or lifted safely. β

Lift
Lifting Direction

The clutch can be used to lift in any direction but angles must not exceed
β=60o as shown in Fig. 2. The anchor’s load limit and angle reduction factors
must be observed.

Releasing Fig. 3

To release, remove tension from the chains and, with the clutch in hand, pull
the locking bolt towards the main body as shown in Fig. 3. The clutch will now
be released.

Pitching / Turning Units
When pitching and turning units using Erection Anchors the direction of the lift
with the Ring Clutch should be a maximum of 90o to the panel as shown in Fig.

Ring Clutches - Maintenance and Examination
In line with industry lifting regulations, all Ring Clutches should be examined by a qualified engineer every six
months from the date of the original test which is supplied when new. Providing they are treated with care,
Ring Clutches can be re-used indefinitely. However, before every lift, it is essential that each clutch be
checked for damage and wear. LFS do not authorise or guarantee the safety of any item that has had any repair
other than the replacement of worn locking pins. Ring Clutches with wire rope must only be used with the
original cables supplied when new.

Wire Cable Loops
Before using a Ring Clutch with a Wire Rope it should be checked for damage such as broken braids, kinking,
corrosion, damaged ferrules or slipping of wires within, separated braids or broken wires at any point on the
rope. Wire ropes should not be in contact with corrosive substances such as acids or alkalis and should be
replaced when any damage is observed.
When using always select a large diameter crane hook as the pressure exerted by smaller hooks can cause
premature damage and wear to the wire.
LFS can replace worn wire ropes on request.
For any further information please contact LFS.

Rubber Recess Formers
These are used for mounting anchors to wooden formwork or floating installation for
all variations of Spread Anchors. A smaller version is available for Universal Anchors.
The former has a metric thread and a bayonet fixing to allow the user to install
through the side of either wooden or steel formwork with threaded bar. These are
made from a hardwearing and flexible rubber and have a plastic insert that surrounds
the anchor to help prolong the life of the former. Available in all load groups.

Steel Magnetic Formers
Used for mounting anchors to steel moulds or formwork beds. Special variations are
available to order

Metal Nailing Plates
Used for attaching anchor to wooden formwork.

Former Closer
For securely closing the former during floating installations.

Installing Anchors
When installing anchors, always be sure to use the appropriate former for the formwork being used and ensure
that it is firmly attached to prevent it becoming dislodged when pouring concrete. Always ensure that the
former is greased to allow easy removal once the concrete is set and that the possibility of air pockets is
eliminated with vibration or an equally effective method. To remove the former use two steel bars in a scissors
action as shown below being careful not to cause any damage and remove any excess concrete prior to lifting.
Always ensure formers are in suitable condition before casting and replace when worn out.
