Composition of Tower Crane Hoisting Mechanism

The hoisting mechanism of a tower crane consists of components such as a hoisting motor, reducer, brake, gears, and wire rope.  

I. Hoisting Motor

The hoisting motor of a tower crane is the power source of the entire hoisting mechanism, mainly composed of components such as a motor, commutator, brake, and bearings. The hoisting motor can quickly and smoothly lift and lower loads, and has the characteristics of strong power, low noise, and long service life.

II. Reducer

The main function of the reducer is to convert the high-speed rotation of the motor into low-speed rotation that can provide huge torque. The reducer usually includes components such as a reducer housing and gears. The structure of the reducer varies depending on the model of the tower crane.  

III. Brake

The brake is a key component in the hoisting mechanism. It can quickly brake and stabilize the load when needed. The brake usually consists of components such as friction plates, springs, a brake body, and a brake housing.  

IV. Gears

Gears are usually made of steel and are used to transmit the rotational torque generated by the motor. They have the characteristics of wear resistance and high load-bearing capacity. The types, quantities, and specifications of gears used in different tower cranes vary.

V. Wire Rope

The wire rope is the main carrier for load transmission in the hoisting mechanism. It has the advantages of wear resistance, high strength, and corrosion resistance. The quality and diameter of the wire rope have an important impact on the safety and stability of the hoisting mechanism.

In summary, the hoisting mechanism of a tower crane is completed by the synergistic effect of the above key components to lift and transport loads. The principle of the synergistic effect of these components is: the hoisting motor provides power, the reducer converts the power into low-speed and high-torque force, the brake stabilizes the load, the gears transmit power, and the wire rope transmits the load to the destination.
