Parts of a Tower Crane
Tower cranes allow the construction industry to make various incredible structures. These cranes have been utilized to reach ever-increasing heights. Tower cranes offer the means to raise and move building parts, supplies and tools all around a construction site. There are various parts that assemble a tower crane when they are put together. Putting a tower crane together utilizes various pieces of construction equipment.
Base
Typically, the tower crane base is made from a steel unit. The base is connected to a custom-designed concrete pad. This set-up provides the structure with stability. Overall, the construction must be well engineered and built in order to operate at optimum safety.
Mast
The mast of the tower crane provides height to the machinery. The mast is made of connected steel sections. The amount of parts determines the height of the crane. Normally, a tower crane has a design that enables the mast to grow during construction by adding further sections as the building process continues. This way the crane's height could be specified, making sure that it has sufficient height to safely and efficiently carry out the needed work.
Slewing Unit/Top Climber
A slewing unit is located at the top of the mast. This unit houses the machinery and the motor which allows the crane to rotate. A top climber is the piece of machinery that allows the mast to grow. The top climber sits just underneath the slewing unit. Hydraulic rams inside the top climber allow the slewing unit to be detached from the mast by raising it higher.
Boom
The term "boom", refers to the working arm of a tower crane. The boom is made up of separate steel parts that are attached together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley attached to the bottom that could extend the length of the boom. This particular trolley holds the hoisting device.
