Tower cranes typically use a combination of fixed and movable pulleys to lift and lower heavy loads. The pulleys are usually attached to the jib or boom of the crane and are used to change the direction and increase the mechanical advantage of the lifting system.

Some common types of pulleys used in tower cranes include:
1. Fixed Pulleys: These are stationary pulleys that are mounted at a fixed point on the crane. They change the direction of the lifting force and help distribute the load evenly.
2. Movable Pulleys: These pulleys are attached to a movable block that can be raised or lowered along the jib or boom of the crane. They provide additional mechanical advantage and allow for easier lifting of heavy loads.
3. Trolley Pulleys: These pulleys are used in conjunction with a trolley system that allows the crane to move horizontally along the jib or boom. The trolley pulleys help distribute the load evenly and provide smooth movement of the crane.
4. Counterweight Pulleys: Tower cranes often use a counterweight system to balance the load being lifted. Counterweight pulleys are used to attach the counterweights to the crane and ensure proper balance and stability.
It's important to note that the specific configuration and number of pulleys used in a Tower Crane can vary depending on the crane model and lifting capacity.
