Crane Control Handles / Pendant Controller and Remtor Controller for Crane and Hoist

Crane control handles can be a wire pendant, wireless remote control or radio control, etc. It can be used to control electric hoist, trolley crab, open winch hoist, etc. on the overhead crane or gantry crane. The wire pendant is usually with rated voltage below 500V, rated current below 15A, which can work in the rain and snow, dusty environment. The wireless remote control handle are different in size. It can be a handle piece or a control panel with joystick (This kind is for large cranes).

Wire Rope Pulley for electric hoist, winch and hook blocks

Crane wire rope pulley is for bearing crane wire ropes with hooks. Weihua customizes pulley blocks for your electric hoists and cranes. We also provide other Crane Components including Electric Parts and Crane Accessories.

pulley blocks

1. Application scope: Electric hoist, cranes
2. Electric hoist pulley is simply constituted by some fixed pulleys and movable pulleys.
3. Electric hoist pulley is widely used in cranes, winches and elevators.
4. Its functional principles could be summarized like this: when the number of wire-rope strands is odd, the rope end should be fixed on the movable pulley, and when the number is even, the rope ends should be fixed on the fixed pulley; when the number is even, should reduce one fixed pulley; when the pulling direction is opposite to the moving direction of weights, should add one fixed pulley.
5. For light and medium duty overhead crane, its pulley could be cast by gray cast iron HT15-33 and ductile iron QT-10; for heavy duty overhead crane, the material could be cast steel ZG25 or ZG35; and for big-diameter (D＞800mm) pulley, it could be welded by carbon steel Q235-A.

Crane Wire Rope Drum Hydraulic Brake

Crane brake is an important parts for Overhead Crane or Gantry Crane, which can decelerate and stop the wire rope drum rotation of a crane.

Crane brake

1. Application: Crane wire rope drum brake is for the moving parts deceleration.
2. There are 2 types: friction brake and non-friction brake.
3. Crane brake is mainly constituted by brake pad, brake arm, brake wheel and brake releaser.
4. To reduce the braking torque and the size of brake frame, the brake is usually installed on the high-speed shaft. To meet the needs of high safety for large machinery, like mine hoist and elevator, the brake should be installed on the low-speed shaft which next to the working parts the large machinery.
