Apr 11, 2023 · Tower cranes arrive at the construction site on 10 to 12 tractor-trailer rigs. The crew uses a mobile crane to assemble the jib and the machinery section, and places these horizontal members on a 40-foot (12-meter) mast that consists of two mast sections.

- Working Arm
- Hook and Trolley
- Operator Cab
This is the most crucial part of the crane that supports the entire structure. It is made of concrete that has been poured a few weeks before the crane assembly commences. The crane is anchored to this base.
The mast refers to the truss-shaped columns that give the crane its working height. Instead of being one continuous column, they are designed to be bolted to each other and other crane components. The concrete base and the mast columns impart stability to the crane and prevent it from toppling over.
Also known as the jib, this extends perpendicular to the mast, and houses the hook and trolley that lift the load.
The hook is the main load-bearing component that hauls loads. It is attached to a trolley that allows the hook to raise and lower, as well as move towards and away from the mast. This is done with the help of cables and pulleys attached to the trolley.
This is the control center of the crane and is attached to the slewing unit. In order to get to the cab, the operator must climb a series of ladders within the mast.

Nov 12, 2020 · A tower crane is always built in three distinct phases: A concrete foundation is prepared so that the crane will be safely anchored to the ground and stable during lifting. A mobile crane assembles the tower crane, lifting several segments of tower into place along with core components.
Jun 28, 2023 · Some tower cranes are constructed inside the buildings they're creating and then torn down again later. Occasionally, cranes are built in elevator shafts for convenience or, as in the case of the fateful World Trade Center, at the four corners of the building, moving upward as the building itself ascends. Tower cranes rotate in two different ways.
