Pre-assembly of many components greatly reduces the
set up time onsite and can be started well in advance of
the site being ready to install the formwork.
Pre-assembly of the formwork is carried out using fabrication jigs and
can also be done well in advance of the actual site set up (on or off
In some cases, by prior arrangement, the fabrication of the formwork panels can be
assembled off site, then transported to site fully assembled and ready to install. This
can save space on congested work sites.
Larger panels that are too big to be transported by road can be assembled
The formwork panels are then prepared and oiled prior to lifting into
The Internal Rigid Boxes are installed first and fixes the internal
shape/dimensions of the core – this is a unique feature of the
Tru-lift Self Climbing Formwork System.
The Steel Walers are easily spliced to any length enabling very large panels
such as this 4.2m high x 20m long panel to be fabricated and lifted into
position in one piece.
Bolts and Grid Plates are used for the connections between the grid beams, the
Formwork and Hydraulics.
Top Decking and Edge Protection are added upon completion of the Grid
The Tru-lift Self Climbing System is operated from a central control
room. Each of the Hydraulic Rams can be controlled individually or
collectively with the flick of one switch.
The Tru-lift Self Climbing System is generally mounted to the walls of
the first pour. However if the customer would prefer, it can be designed
to form the first pour and push off the base slab as was done on this
The Tru-lift Self Climbing System is truly unique in that the whole system is
jacked in one Jack stroke, eliminating the need for resetting the hydraulics
throughout the lift saving a great deal of time. On this particular project the 3.8m
typical floor height was easily accommodated by jack stoke and capacity.
The Tru-lift Self Climbing System is to be used to form the first
pour. The Hydraulic Rams should be prevented from movement by
setting brackets around the bottom of it into the base slab.
External Hanging access brackets are
added on the initial lifts until the
desired length is achieved.
scaffolds can also be
accommodated as seen
here from below.
Rebar cages can be prefabricated and craned into position to speed up the
cycle times if desired.
When the setup is complete the Tru-lift self climbing system is
operated completely independently, without the need for a crane
to handle the Formwork and easily out performs traditional
Jump form systems.
The contractor using the Tru-lift System on this particular project was able to
achieve a pour cycle of just 48 hours with 1,100m2 of formwork being jacked in
Upon completion of the structure the system is dismantled in the reverse order to
that of the erection.
