Crane Cable Chains

Description of Drag Chains:
Crane cable chains is a way for crane power supply. The power cable is built-in the drag chains for cable moving and protection.

Drag chains can be made by steel and plastic. Steel drag chains are made of steel and aluminum and can be customized. Drag chains are classified into bridge drag chains, fully enclosed drag chains, and semi-closed drag chains according to the use environment and requirements.

Drag Chains:

Application of Cable Chains:
The drag chain is used for the occasions of reciprocating motion, and it can traction and protect the built-in cables, oil pipes, air pipes, water pipes, etc. Drag chains have been widely used in CNC machine tools, electronic equipment, glass machinery, injection molding machine manipulators, handling machinery, plastic machinery, lifting equipment, woodworking machinery, automotive industry, industrial vehicles, metal processing machines, machine tools, casting machinery, port equipment, etc.



Features of Crane Drag Chain:
1. Especially designed for horizontally moving loaders and large cranes.
2. Modular design and fewer components significantly reduce installation time.
3. Good price, variable material and specifications.
4. Full sets including bracket, guide groove, and clips.
5. The drag chain or cable can be directly inserted into the guide groove. It can flexibly meet the installation needs of consumers in any environment.

Wire Rope for hoist, winch and crane

Wire rope is applicable for Overhead Crane, Gantry Crane, container cranes, shore crane, crawler cranes, offshore fixed cranes, pile drivers, ship unloader cranes, etc. Crane wire rope is constituted by steel wire, rope core and grease.

Wire rope

Features of Crane Steel Wire Rope:
1. Application: Lifting, towing, straining and load bearing of electric hoist or winch.
2. High strength with more than 1770Mpa tensile strength, large capacity, strong overload capacity, good elasticity, impact resistance and light self-weight.
3. Crane Wire Rope has good flexibility, stable operation and low noise during high-speed movement. Because it needs to be wound on multiple layers on the reel, it should have good bending fatigue performance.
4. It is reliable in work and will not break suddenly. This is a necessary condition for lifting and safe work.



According to the above features, we generally recommend that customers wire-contact wire ropes, such as 6*36SW. In special occasions, we recommend customers 8*36SW or compacted wire ropes.

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.
