What is the Primary Hoisting Mechanism in a Tower Crane?
The primary hoisting mechanism in a tower crane is the wire rope hoist.
How it Works:
l A powerful electric motor drives a drum that rotates.
l A steel wire rope is wound or unwound around this drum.
l The rope is attached to the hook at the end of the crane's boom.
l When the motor turns the drum clockwise, the rope winds up, lifting the hook and any attached load.
l When the motor reverses, the rope unwinds, lowering the load.
Key Components:
l Electric Motor: Provides the power to rotate the drum.
l Drum: The central component around which the wire rope winds.
l Wire Rope: The strong, flexible cable that connects the drum to the hook.
l Hook: The attachment point for the load.
