Common Used Tower Crane Hoisting Mechanism

The Hoisting Mechanism for a Tower Crane typically consists of a combination of a motor, a gearbox, Wire Rope, and a hook block.

During operation, the Tower Crane Hoist Motor drives the hoisting drum through the gearbox. As the drum rotates, the wire ropes are wound or unwound, depending on the direction of rotation. This movement raises or lowers the hook block, allowing the tower crane to lift or lower loads.
The hoisting mechanism is controlled by the crane operator using various controls and switches. Safety features such as limit switches and overload protection systems are also incorporated to prevent accidents and ensure safe lifting operations.

JLF series mechanism and LFV series mechanism are two types of the most common used hoisting mechanism for tower crane recently. The mechanisms adopt AC asynchronous tower crane hoist motor and frequency control system with features of high efficiency, wide range of speed regulation, large rope capacity, stepless speed regulation, high-voltage dynamic performance,etc.It is applicable to building construction, precise hoisting, large rated hoisting weight and other construction sites.
