Crane parts introduction

1. Wire Rope
Function: It is an important part of the lifting mechanism and the amplitude changing mechanism of the crane, which is used to carry heavy objects and realize the lifting and lowering action.
Features: With high strength, wear resistance, corrosion resistance and other characteristics. According to different crane types and work needs, the diameter, structure and material of the wire rope will also be different.
Two, the hook
Function: Used to connect the crane and heavy objects, is a key part of the crane lifting heavy objects.
Features: The hook is usually made of high-quality alloy steel, with high strength, high toughness and good wear resistance. The shape and size of the hook will also vary according to different lifting needs, common single hook and double hook.
Three, pulley
Function: Change the movement direction of the wire rope, play a role in saving labor and increasing the lifting height.
Features: Pulley is generally made of cast iron, cast steel or nylon and other materials, with good wear resistance and bearing capacity. The diameter and groove of the pulley will also be selected according to the diameter of the wire rope and working conditions.
Four, brake
Function: When the crane stops running, the moving parts of the crane are braking to ensure the safe operation of the crane.
Characteristics: The brake usually adopts electromagnetic braking or hydraulic braking, which has the characteristics of reliable braking and rapid response. The braking torque of the brake will also be selected according to the lifting weight and working level of the crane.
Five, reducer
Function: Reduce the output speed of the motor and increase the lifting torque of the crane.
Features: The reducer is generally composed of gear, shaft, bearing and other components, with high transmission efficiency, low noise, long life and so on. The type and parameters of the reducer will also be selected according to the lifting weight and working speed of the crane.
Six, coupling
Function: Connect motor and reducer, transfer power and torque.
Features: Coupling usually adopts elastic coupling or gear coupling, with good cushioning and damping performance and transmission accuracy. The type and parameters of the coupling will also be selected according to the shaft diameter and speed of the motor and reducer.
7. Wheels
Function: Support the crane's operating mechanism, so that the crane can walk on the track.
Features: Wheels are generally made of cast steel or forged steel, with high strength, high hardness and good wear resistance. The diameter of the wheel and the shape of the rim are also selected according to the lifting weight of the crane and the type of track.
Eight, electrical control system
Function: Control the lifting, falling, walking and other actions of the crane, to realize the automatic operation of the crane.
Features: The electrical control system is generally composed of motors, controllers, contactors, relays and other components, with high control accuracy, rapid response, strong reliability and other characteristics. The type and parameters of the electrical control system will also be selected according to the working needs of the crane and the control mode.
In short, the quality and performance of crane accessories directly affect the safe operation and work efficiency of the crane. In the selection of crane accessories, should be based on the type of crane, lifting weight, work level and other factors for comprehensive consideration, the choice of reliable quality, stable performance of the accessories products.
