This document discusses the installation and use of tower cranes on construction projects. It defines cranes and describes different types, including tower cranes. The key components of tower cranes are described as the base, climbing tower, swing ring, boom, and counterweight. The erection procedure and utility of tower cranes for lifting heavy loads and transporting them horizontally is outlined. Some disadvantages are that they are cumbersome to erect and dismantle and require skilled operators. Statistics are provided comparing project metrics like concreting time and labor needs with and without a tower crane.

3.  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

4. 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.

18. 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

19. 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
