Lifting Tower Crane for Sale
Tower crane is a fully slewing jib crane with a tower-like structure. It is a
common means of transportation in large civil engineering
construction sites. It can move construction materials and
construction machinery up and down in a crisscross direction. The
task of moving objects can be completed quickly. One end of the
tower crane is used to lift objects, the middle is a control cabin,
and the other end is balanced with a giant concrete block. Tower
cranes are usually fixed in the center of a building so that
objects can be moved to different locations and heights.
Tower cranes are a modern form of balanced cranes that consist of
the same basic components. Tower cranes are fixed to a concrete
slab (sometimes attached to the side of the structure) and usually
provide the best combination of height and lifting capacity for the
construction of high-rise buildings. The base is then connected to
the mast, which gives the crane height. In addition, the mast is
connected to a slewing unit (gear and motor) that allows the crane
to rotate. There are three main parts on top of the slewing device:
the working boom, the jib, and the cab. The working boom is the
part of the crane that carries the load. The jib carries a
counterweight, usually a concrete block. The tower crane can be
controlled by the cab or a wireless remote control. The cab is
usually located on top of a tower connected to a turntable and can
be mounted on a boom. The lifting hook is operated by the crane
operator using an electric motor. The hook is located on a winch on
a long horizontal arm and is used to lift construction materials.
The optimal location of the tower crane on the construction site
has a significant impact on the material transportation costs of
the project.

has reached the international advanced level.
