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.
