Tower Crane

TOWER CRANE

Driscoil Equipment supplies heavy-duty Tower Cranes designed for high-rise construction, infrastructure development, industrial projects and heavy material handling. Tower cranes provide high lifting capacity, substantial working height and long horizontal reach while operating from a compact base footprint.

Major Components

1. Mast / Tower Sections

The vertical mast consists of modular steel sections bolted together to achieve the required working height.

2. Jib

The horizontal jib provides the crane's working radius and carries the trolley and lifting system.

3. Counter-Jib

The counter-jib balances the main jib and supports the counterweights and associated machinery.

4. Hoisting Mechanism

The electric hoist system raises and lowers loads using a high-strength wire rope and hook block.

5. Slewing System

Heavy-duty slewing motors rotate the upper crane assembly around the vertical tower axis.

6. Trolley System

The trolley travels along the jib, allowing the operator to move the load toward or away from the tower.

7. Operator Cabin

The cabin contains the crane controls, instrumentation, monitoring systems and safety controls.

8. Counterweights

Engineered counterweights provide the necessary balance between the lifted load and crane structure.
