TOWER CRANE
INSTALLATION WORK
 Introduction
 Types of Crane
 Different Components
of Crane
 Erection Procedure
 Utility to Project/Site
 Disadvantages
 Statistical Analysis
Topics : -
 Definition : 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.
Introduction: -
Types of Tower Crane
 Ancient Crane
 Mobile Crane
 Telescopic Crane
 Tower Crane
 Loader Crane
 Stacker Crane
 Gantry Crane
 Overhead Crane
Uses of Tower Crane :
 It is mainly used for lifting heavy things and
transporting them to other places.
 It uses one or more simple machines to create
mechanical advantages and thus move loads
beyond the normal capability of a human.
 Cranes are commonly used in transport
industry, in the construction industry (real
estate) for the movement of materials and in
the manufacturing industry for the
assembling of heavy equipment's.
Different Component's of Crane -
Erection Procedure :
The Base
Climbing Tower
Swing Ring
Boom
Boom
Operator’s
Cabin
Counter Weight
Load Carried by the Boom
Sr no.
Distance from the mast
(In meters)
Load Carrying Capacity
(In MT)
1 10m 6
2 20m 4
3 30m 3
4 40m 2
Utility to the Projects
Time Saving Machine
Multipurpose in Use
Heavy Duty
High Performance
Ease even in Critical Situation
Can be transferred from on project to
another
Optimum Utilization of Resources
Disadvantages
Cumbersome to erect & Dismantle
High Initial cost for erection as well
as dismantling
Skilled operators are required
Maintenance is difficult
Sometimes creates safety problems
Limited for the projects with large
areas
Statistical Analysis
