The document describes the basic components and functions of both hydraulic mobile cranes and tower cranes, including their booms, counterweights, outriggers, jibs, and operator cabs. It explains that hydraulic mobile cranes use a two-gear pump system to lift loads, while tower cranes have a mast or tower and can climb vertically as the building rises. Both crane types must be properly balanced using counterweights and outriggers to safely lift and move heavy loads.

This Presentation consists of details about the various Hoisting and Transporting Equipments In details.The concepts has been explained thoroughly with the help of Diagrams and various pictures related to the topics.
Cranes are mostly used in the construction of towers, building and industry, and in manufacturing heavy equipments. Hydraulic Crane is used as one of the best cranes in the industry.
The hoisting is the lifting of the material against gravity and maybe done with a wide range of equipments from the small hand operated simple screw or hydraulic-jack to modern high powered cranes and elevators.
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.
The technology for hoists is always improving. Chain hoists have become more durable, and new hoists are designed with lower headrooms. Currently, both electric chain and wire rope hoists are appropriate for typical factory applications in capacities to 7.5 tons.

This handbook provides the basics of crane operation and safety requirements as well as guidelines for the initial investigation of crane incidents, including observations to be made at the site as well as questions to be asked during interviews of site personnel.
selection operation and maintainance of mobile cranes ( for education purpose...swaroop k s
A mobile cranes are machine that could lift, pull, tug, carry, and do many such things that are done on a large scale. It is a cable-controlled crane mounted on crawlers or rubber-tired carriers or a hydraulic-powered crane with a telescoping boom mounted on truck- type carriers or as self-propelled models. They are commonly used in the construction industry and in the manufacturing of heavy equipment.
Rough Terrain Crane A crane that is mounted on an undercarriage with four rubber tires, designed for operations off road. The outriggers extend vertically and horizontally to level and stabilize the crane when hoisting. These types of cranes are single engine machines where the same engine is used for powering the undercarriage as it is for powering the crane. In these types of cranes, the engine is normally mounted in the undercarriage rather than in the upper portion.
These cranes can go from the paved highway to the rocky landscape of a job site. They can reach speeds necessary to travel on public highways, yet have the power necessary to handle a variety of construction tasks. This mainstay of the heavy equipment industry main asset is its versatility. All terrain cranes can handle up to 1,300 short tons of weight
Telescopic handler cranes are essentially forklift trucks with a telescoping boom attached to them. These cranes can be driven in 360 degrees and are often used for tasks like moving pallets of bricks or hoisting framing trusses in place.

Crane Incident Handbook, by R. John Phillips, P.E., CFEIMattWarren37
Cranes are powerful lifting devices that we see everyday in construction areas, shipping terminals, and industrial sites. They are so common that we often pass by them with little thought. Cranes, however, can sometimes become involved in incidents that injure people or damage equipment.
This handbook provides the guidelines for the initial investigation of crane incidents, including observations to be made at the site as well as questions to be asked during interviews of site personnel.
Here is a PDF version of the Crane Incident Handbook . If you have questions about the material contained in this publication you can contact John Phillips at jphillips@warrenforensics.com.
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.
This research work was given by Shri. Adolphus M.G.D. Gleekia, senior lecturer at the University of Liberia during Mine 417 lectures to get an in depth understanding and technical evaluation of bucket capacity, XCMG-90-tons dumper and its working capacity, excavators, components of an excavator, types of excavator, electric shovel, components of an electric shovel, differences between long ton and short ton and the tonnage factor.
This research also focuses on the working capacities of those mining equipments and a vivid images for identification.
The calculations of the bucket capacity, tonnage factor and conversions factors of long ton and short ton was also examined.

2. HYDRAULIC MOBILE CRANE
• Basic Equipment
• Some basic equipment on
a hydraulic truck crane:
– Boom - The large arm mainly responsible
for lifting
– Counterweights - Multi-ton weights
placed on the back of the cab to prevent
the crane from tipping during lifts
– Two-gear pump - Hydraulic pump
system that uses two rotating gears to
pressurize oil
– Jib - Lattice structure that extends out of
the boom
– Outriggers - Supports that keep the
crane balanced
– Rotex gear - Large gear under the cab
that allows the boom to be rotated
– Load Moment Indicator - Array of lights
located in the cab just above the
operator's eye level; flashes if crane's
lifting limits are reached
3. HYDRAULIC MOBILE CRANE
• The large metal ball attached to
the hook keeps the cable taut
when there is no load on the
hook.
• The large metal ball attached to
the hook keeps the cable taut
when there is no load on the hook.
• If the operator tries to lift a load
too high, the Load Moment
Indicator will light up.
4. HYDRAULIC MOBILE CRANE
• The outriggers • The outriggers keep

5. TOWER CRANE
• Parts :
– Base
– Slewing Unit
• Jib / Working
Arm
• Machinery
Arm and
Counterweig
ht
• Operator
Cab.
– Mast / Tower
6. TOWER CRANE
• The long horizontal jib (or • The shorter horizontal
working arm), which is the
portion of the crane that machinery arm, which
carries the load. A trolley contains the crane's
runs along the jib to move motors and electronics as
the load in and out from the
well as the large concrete
crane's center counter weights
7. TOWER CRANE
• The operator's cab: • The machinery arm contains the motor that
lifts the load, along with the control
electronics that drive it and the cable drum,
as shown above :
• The motors that drive the
slewing unit are located above
the unit's large gear.
8. TOWER CRANE
• Spesification :
– Maximum unsupported height - 265 feet (80
meters)
The crane can have a total height much
greater than 265 feet if it is tied into the
building as the building rises around the
crane.
– Maximum reach - 230 feet (70 meters)
– Maximum lifting power - 19.8 tons (18
metric tons), 300 tonne-meters (metric ton =
tonne)
– Counterweights - 20 tons (16.3 metric tons)
9. TOWER CRANE
• The first element of the tower crane's stability is a large concrete
pad that the construction company pours several weeks before the
crane arrives. This pad typically measures 30 feet by 30 feet by 4
feet (10 x 10 x 1.3 meters) and weighs 400,000 pounds (182,000
kg) -- these are the pad measurements for the crane shown here.
Large anchor bolts embedded deep into this pad support the base
of the crane. So they can’t fall over even without support of wire.
When watching a hydraulic truck crane in action, it's hard to believe just how much weight it's moving because it deals with these multi-ton objects with relative ease. Hydraulic truck cranes vary in lifting power. It's easy to tell how much a particular hydraulic truck crane can lift just by the name of it: A 40-ton crane can lift 40 tons (80,000 lb or 36,287 kg).
