A hoist is a device that is used to lift or lower the load attached to it by the means of a lift wheel or drum. The lifting of the load is done by the rope or wire that is looped around the wheel or the drum. The wheel or the drum may use electricity for its operation or in some cases it may also be manually operated. Along with the drum and the wire, another integral part of the hoist is the lifting medium that is used. The different lifting mediums that are used are chain, fiber or wire rope. A hook is also available where the load is attached.
Dragline machine at dhudhichua project ,singrauliTauhid Mohammad
A dragline excavator is a piece of heavy equipment used in civil engineering and surface mining.
Draglines fall into two broad categories: those that are based on standard, lifting cranes, and the heavy units which have to be built on-site.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

2. INTRODUCTION
Hoisting is the lifting a weight from one location
and moving it to another location which is at a
reasonable distance.
Big projects such as, construction of dams,
industrial buildings etc. require hoisting
equipment.
Hoisting equipment includes jacks, winches,
chain hoists and cranes.
Crane is the only single machine which, as a
single piece, is capable of providing three-
dimensional movement of a weight.
3. CRANE
A crane is a type of machine, generally equipped
with a hoist rope, wire ropes or chains,
and sheaves,
It can be used both to lift and lower materials and
to move them horizontally. It is mainly used for
lifting heavy things and transporting them to other
places.
It uses one or more simple machines to
create mechanical advantage and thus move loads
beyond the normal capability of a human.
4. MECHANICAL PRINCIPLE
Major considerations in the design of cranes.
the crane must be able to lift the weight of the
load; second.
the crane must not topple.
the crane must not rupture.
The Principles involved are
Lifting capacity
Stability
5. Main Basic Lifting Parts Of The Crane:
Lever
Pulley
The hydraulic cylinder
A balance crane contains a horizontal beam
(the lever) pivoted about a point called the fulcrum.
A jib crane contains a tilted strut (the jib) that
supports a fixed pulley block. Cables are wrapped
multiple times round the fixed block and round
another block attached to the load.
For stability, the sum of all moments about any
point such as the base of the crane must equate to
zero.
6. TYPES OF CONSTRUCTION
CRANES
1) Mobile cranes
2) Fixed cranes
A fixed crane is the type of crane which
lift the loads without any appreciable
movement.
A mobile crane is the type of crane
which moves from one place to another as well
as movement of the crane basic tools.
7. MOBILE CRANES
The most basic type of mobile crane consists
of a truss or telescopic boom mounted on a mobile
platform be it on road, rail or water. Common
terminology is conventional and hydraulic cranes
respectively.
These cranes are mounted on mobile units
which is either crawler type or wheel type.
8.
9. TYPES OF MOBILE CRANES
1) Truck mounted
crane
It is the cranes mounted on
a rubber tire truck will
provide great mobility.
The truck cranes have a
self-contained telescoping
boom.
In case of larger machines,
the width of the out
triggered vehicle may
reach 40ft.
10. Common dimensions and capacity:
1) Max Boom length : 70 to 170 ft
2) Maximum fly-jib length : 30 to 100ft
3) Maximum radius (boom only) : 60 to 140 ft
4) Minimum radius : 10ft
5) Maximum lifting capacity : 20 to 120 ton
6) Maximum travel speed : 40 to 70 mph
7) Number of axles : 3 to 4
11. 2) Lattice-Boom truck –mounted
cranes
Lattice boom structure is
light weight.
Reduction in boom weight
means additional lift
capacity, as the machine
predominately handles hoist
load and less weight of
boom.
It does take long time to
assemble.
12. Common dimensions and capacity:
1) Max Boom length : 170 to 470 ft
2) Maximum fly-jib length : 40 to 300ft
3) Maximum radius (boom only) : 130 to 380 ft
4) Minimum radius : 10 to 25ft
5) Maximum lifting capacity : 50 to 600 ton
6) Maximum travel speed : 40 to 60 mph
7) Number of axles : 4 to 8
13. 3) Rough terrain cranes
A crane mounted on an
undercarriage with four
rubber tires that is
designed for pick-and-
carry operations and for
off-road and "rough
terrain" applications.
It can move on slopes
upto 70%.
Most have 4 wheel drive
and 4 wheel steering
which allows them to
traverse tighter and
slicker terrain than a
standard truck crane with
less site preperations.
14. Common dimensions and capacity:
1) Max Boom length : 80 to 140 ft
2) Maximum fly-jib length : 20 to 90ft
3) Maximum radius (boom only) : 70 to 120 ft
4) Minimum radius : 10ft for most of the models
5) Maximum lifting capacity : 20 to 90 ton
6) Maximum travel speed : 15 to 35 mph
7) Number of axles : 2 for all models
15. 4) All terrain cranes
Designed with an
undercarriage capable of
long distance of long
distance highway travel.
Yet the carrier has all-axle
drive and all wheel steering.
Crab steering, large tires
and High ground clearance.
Has dual cabs, a lower cab
for fast highway travel and
a super structure cab that
has both drive and crane
controls.
16. Common dimensions and capacity:
1) Max Boom length : 100 to 270 ft
2) Maximum fly-jib length : 30 to 240ft
3) Maximum radius (boom only) : 70 to 250 ft
4) Minimum radius : 8 to 10ft
5) Maximum lifting capacity : 30 to 300 ton (max. 800ton)
6) Maximum travel speed : 40 to 55 mph
7) Number of axles : 2 to 6 for (upto 8 or 9)
17. 5) Crawler crane
A crawler crane is a crane
mounted on an undercarriage with
a set of tracks (also called
crawlers) that provide stability and
mobility.
Lifting capacity from about 35 to
40 tones
This particular asset class is ideal
for working in confined or small
area where a big crane can not
reach.
Crawler crane command their
position at many of power plants,
thermal plants and at big infra
projects.
These crane are well suited for
piling, drilling and pipe laying
operation by just adding suitable
attachment.
18. 6)Railroad crane
Rail road crane is one of the
mobile crane type. The name tells us
that this crane runs on rail tracks.
A railroad crane is specifically
designed with flanged wheels so it
can travel along railroad tracks.
Although the design differs according
to the type of work, the basic
configuration is the same in all cases
which is a rotating crane body is
mounted on a sturdy chassis fitted
with flanged wheels.
Uses:
1.For lifting the goods at station yards.
2. It may be used for installing signalling
equipment or pointwork, for example,
while more specialised types are used
for track laying.
19. 7) Floating crane
Floating crane is one mobile crane,
they are sea vessels have crane
mounted on them or ships equipped
with cranes but not like deck crane.
They are mainly used in building
bridges and port construction.
They are capable of carrying whole
sections of bridge through the water
and installing it in position due to
their loads capacity which exceeds
10,000 ton their capacity of loading
is great.
Floating cranes are the ideal choice
for cargo handling on waterways .
Floating crane are mobile and can
be used in rivers (mid-stream
transshipment), in ports, in
protected waters, in coastal waters
and on the open sea.
20. Tipping condition
When a crane lifts a load attached to the hoist line that
passes over a Sheave located at the bottom point of the
machine, there is a tendency to tip the machine over.
Tipping load – The load that produces a tipping
condition at a specific radius.
A Partial safety factor with respect to tipping
is introduced by PCSA
1) Crawler-mounted machines = 75%
2) Rubber-tire mounted machines =85%
3) Machines on outriggers = 85%
21. Load capacity will vary depending on the
quadrant position of the boom with respect to
machine’s under carriage.
In case of crawler cranes,
1) Over the side
2) Over the drive end of the tracks
3) Over the idler end of the tracks
In case of wheel mounted cranes,
1) Over the side
2) Over the rear of the carrier
3) Over the front of the carrier
22. Factors that will affect actual crane
capacity on the job
1) Wind forces on the boom or load
2) Swinging the load
3) Hoisting speed
4) Stopping the hoist
23. TOWER CRANES
Tower cranes are a modern form of balance crane
that consist of the same basic parts. Fixed to the
ground on a concrete slab (and sometimes attached to
the sides of structures), tower cranes often give the
best combination of height and lifting capacity and are
used in the construction of tall buildings.
Fixed to the ground.
Horizontal boom is balanced asymmetrically.
Short arm carries a counterweight of concrete blocks.
Long arm carries the lifting gear.
24. COMPONENTS
Mast: The main supporting tower of the crane. It is made of steel
trussed sections that are connected together during installation.
Slewing unit: The slewing unit sits at the top of the mast. This is
the engine that enables the crane to rotate.
Operating cabin: The operating cabin sits just above the slewing
unit. It contains the operating controls.
Jib: The jib, or operating arm, extends horizontally from the
crane. A "luffing" jib is able to move up and down; a fixed jib has
a rolling trolley that runs along the underside to move goods
horizontally.
Counter jib: holds counterweights, hoist motor, hoist drum and
the electronics.[41]
Hoist unit: The hoist unit houses the hoist drum, hoist cable, gear
box, gear shift, brake, and supporting components.
Hook: The hook (or hooks) is used to connect the material to the
crane. It hangs at the end of thick steel cables that run along the
jib to the motor.
Weights: Large concrete counterweights are mounted toward the
rear of the mast, to compensate for the weight of the goods lifted
26. Common dimensions and capacity:
1) Jib length : 100 to 270 ft
2) Mast section length : 10 to 20ft
3) Base dimensions : 13x13 ft to 27x27 ft
4) Tower cross section : 4x4 ft to 8x8 ft
5) Maximum lifting capacity : 10 to 90K lb
6) Maximum lifting capacity at end of jib : 2 to 13k
lb
7) Maximum hoisting speed : 150 to 500 ft/min
8) Maximum trolleying speed : 100 to 350 ft/min
9) Maximum slewing speed : 0.6 to 1.0 rpm
28. Common dimensions and capacity:
1) Jib length : 70 to 150 ft
2) No. of telescoping/ folding mast parts : 2 to 3
3) Base dimensions : 10x10 ft to 15x15 ft

32. Self-Erecting Tower Cranes
Generally a type of
pedestrian operated tower
crane, these cranes, also
called self-assembling, jack-
up, or "kangaroo" cranes, lift
themselves from the ground
or lift an upper, telescoping
section using jacks, allowing
the next section of the tower
to be inserted at ground level
or lifted into place by the
partially erected crane itself.
They can thus be assembled
without outside help, and
can grow together with the
building or structure they are
erecting.
33. Travelling Tower Cranes
The ballasted base of
this type of tower crane
is set on a pair of fixed
rails .
This enables the crane
to move along the rails
with a load.
Increased coverage of
the work area cab be
achieved.
34. Tower Crane selection
Based on
1) Weight, dimension and lift radii of the heaviest
loads.
2) Maximum free standing height of the crane.
3) Maximum braced height of the crane.
4) Crane climbing arrangement.
5) Weight of crane supported by the structure.
6) Available Headroom.
7) Area that must be reached.
8) Hoist speeds of the crane.
9) Length of cable the hoist drum can carry.
