Rope arranging pulley of tower crane

The rope arranging pulley of tower crane is an important component on the tower crane, with the following characteristics and functions:

I. Structure and Material

Structural Design:

The rope arranging pulley of tower crane usually consists of parts such as the wheel body, hub, bearing, and shaft. The wheel body is the main working part of the rope arranging pulley. Its shape is generally cylindrical or conical, and there are certain grooves or protrusions on the surface to guide the arrangement of the wire rope. The hub is located at the center of the wheel body and is used to install bearings and shafts, enabling the wheel body to rotate freely. The bearings play a role in reducing friction and supporting the rotation of the wheel body. The shaft is the installation base of the rope arranging pulley and fixes it at the corresponding part of the tower crane.

The structural design of the rope arranging pulley needs to consider factors such as the diameter of the wire rope, running speed, and load to ensure that it can stably guide the arrangement of the wire rope and reduce the wear and winding of the wire rope.

Material Selection:

The material of the rope arranging pulley of tower crane is usually selected according to its application environment and requirements. Common materials include cast iron, cast steel, nylon, polyurethane, etc. Cast iron and cast steel have relatively high strength and wear resistance and are suitable for heavy-load and high-speed operation occasions. Nylon and polyurethane have lighter weight, good wear resistance and self-lubricating properties, and are suitable for occasions where there are higher requirements for weight or where friction needs to be reduced.

In some special application scenarios, such as high-temperature, corrosive and other environments, rope arranging pulleys made of special materials, such as ceramic and stainless steel, can also be selected. 

II. Application Fields

Construction:

During construction work, the tower crane is a commonly used lifting equipment. As an important component of the tower crane, the rope arranging pulley is widely used in various construction projects. It can guide the arrangement of the wire rope, ensure the normal operation of the tower crane, and improve construction efficiency and safety.

In the construction of high-rise buildings, the tower crane has a greater height and load, so higher requirements are placed on the rope arranging pulley. It is necessary to choose rope arranging pulleys with high strength and good wear resistance to ensure the stable operation of the equipment.

Ports and Wharves:

Ports and wharves are important places for cargo loading and unloading, and tower cranes are also widely used in ports and wharves. The rope arranging pulley also plays an important role in the tower cranes at ports and wharves. It can guide the arrangement of the wire rope and ensure the safe loading and unloading of cargo.

The environment at ports and wharves is relatively harsh, and there are higher requirements for the corrosion resistance and wear resistance of the rope arranging pulley. It is necessary to choose the material of the rope arranging pulley that is suitable for the environment of ports and wharves to extend the service life of the equipment.

Other Fields:

Apart from construction and ports and wharves, the rope arranging pulley of tower crane can also be applied to some other fields, such as mines, electric power, petrochemicals, etc. In these fields, tower cranes are also widely used for lifting and handling operations, and the role of the rope arranging pulley is equally indispensable.
