Tower Crane Parts
Some of the most remarkable structures around the globe are made using cranes. The newer cranes are used to be able to reach higher heights. Tower cranes provide the way to raise and transport materials, tools and building parts around a construction site. There are various components which assemble a tower crane when they are put together. Putting a tower crane together uses different pieces of construction machines.
The tower crane base is normally made from a steel unit. The units' base connects to a custom pad made of concrete. This set-up provides the structure with stability. Generally, the construction must be well engineered and built in order to operate at optimum safety.
The mast on the tower crane provides the machine with its overall height. The mast is constructed out of individual steel sections that are attached together. The amount of sections determines the height of the crane. Usually, a tower crane has a design which enables the mast to grow during construction by adding more parts as the building process goes on. This way the height of the crane can be specified, making certain that it has sufficient height to carry out the required work safely and efficiently.
Slewing Unit/Top Climber
A slewing unit is located over the mast. This unit houses the machinery and the motor which enables the crane to rotate. A top climber is the piece of machine that enables the mast to grow. The top climber is situated just underneath the slewing unit. Hydraulic rams in the top climber enable the slewing unit to be detached from the mast by raising it higher.
The term "boom", refers to the tower crane's working arm. The boom is made up of individual steel sections which are attached together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley connected to the underside that can extend the length of the boom. This trolley has the hoisting mechanism.
