A crane is a machine that uses simple machines like levers and pulleys to lift and move heavy loads beyond human capability. The document discusses the main parts of cranes like levers and pulleys and describes different types of cranes such as mobile cranes, tower cranes, gantry cranes, and jib cranes. It also provides specifications for a POTAIN tower crane model and quotes a price of 85,000 US dollars for the selected crane.

2. INTRODUCTION
 A crane is a type of machine, generally
equipped with a hoist, wire ropes or chains,
and sheaves, that can be used both to lift and
lower materials and to move them
horizontally.
 It uses one or more simple to create
mechanical advantage and thus move loads
beyond the normal capability of a human.

3. CRANE PARTS & ITS MECHANISM

4. 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.

5. Types of crane
Mobile crane
Tower crane
Gantry crane
Wheel-mounted crane
Jib crane
Truck-mounted crane
Crawler crane
Over head traveling crane
Power-Operated Crane
Pulpit-Operated Crane

6. Remote-Operated Crane
Semi gantry Crane
Shop Crane
Wall-Mounted Crane
Wall-Mounted Jib Crane
Automatic Crane
Cab-Operated Crane
Cantilever Gantry Crane
Floor-Operated Crane
Hydraulic crane

7. (a) is used primarily for raising or lowering a
freely suspended load;
(b) is capable of travelling over a supporting
surface without the need for fixed runways
(including railway tracks); and
(c) relies only on gravity for stability, with no
vertical restraining connection between itself
and the supporting surface, and no horizontal
restraining connection (other than frictional
forces at supporting-surface level) that may act
as an aid to stability.
Uses of mobile crane:

8. Heavy lifting for tall
buildings
Max. unsupported height
typically 265’ (80 m)
Much greater heights
when supported by
building’s framework

9. Max. reach 230’ (70 m)
Max. lift 19.8 Tons (18t)
Counter weight = 20 Tons
Maximum load-moment =
300 tonne-meter ex.: 30m
(100’) radius yields a 10t
lifting capacity
Limit switches for max.

10. • This type of crane is
similar to the bridge
crane except that it runs
on a runway at the floor
level. The bridge is
supported by a pair of
rigid steel legs which are
carried by a pair of end
trucks along the floor
level runway.

11. Specifications:-
Lifting Capacity: 5 tones to 10 tones
Working Radius: 23 m
Use:
In the construction of Bridge superstructure for
lifting heavy girder.
In Ship manufacturing industry ,for lifting heavy parts
of ships.

12. • This type of crane consists of a
pivoting head and boom
assembly which carries a hoist
and trolley unit.
• Lifting Capacity: 1 to 300
tones
• Working Radius: 70m
• Use: Jib crane used in ship
yards for lifting heavy
machinery and equipment,
weighing 100 to 300 tons.

13. It is the cranes mounted on a rubber tire truck
will provide great mobility.
• Lifting capacity: 20 to 30 tones
• Working Radius: 15m to 20m
• Use: It is used for the loading and unloading of motor vehicle
rolling stock, for cargoes primarily of a heavy and single-item
nature, and also for construction and repair work.

16. • Overhead Crane can build top running cranes,
under running cranes, double girder cranes,
and single girder cranes ranging from:
• Capacities - 1/4 ton through 100 tons
• Spans - 5' through 125‘
• Use: The most common overhead crane use is
in the steel industry.
