Tower Type Crane
Tower type of cranes are one type of modernize version crane. These
cranes are totally secured with the ground level, or fixed with the walls
of super structures.
Tower type cranes normally prepared as the most suitable kind of arrangement of the up lifting capability
and the height adjustment, and are most suitable options for the high rise
The long boom and the counter-jib are located on the turntable
portions. At the time of suspension
of heavy loads by the jib part, the counter-jib also hold the concrete blocks the
counterweights the moment. The tower type crane is operated from a cabin
compartment, which is located at the tower peak top, or can be
automatically directed by the remote control from the ground level.
Electrically operated motors are actually used to move the wire cables
through sheaves. The crane operator hooks or unhooks the carrying loads by
working in combination with the rigger part. The crane operator and the
rigger always use radio satellite contact or hand signals, for the smooth
crane operation. In generally, during the construction of high rise
buildings, the present height of the tower cranes is considerable points, now
due to which a small type crane or a derrick structure is simultaneously used
for the disassembly of the tower type crane.
