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.

Powerail Busbar Conductor Rail System for Overhead Crane

Conductor rail system can be the single pole conductor bar system, seamless conductor rail system, and solid steel conductor rail system. As a leading crane manufacturer, Weihua provides all kinds of power supply systems for cranes.

Conductor rail system

1. Single-Pole Conductor Bar System
The single pole conductor bar materials are copper (200A-5000A) and aluminum (150A-3000A). The aluminum conductor bar is provided with a proven stainless steel contact surface (There is no need to add stainless steel strip in case the conductor used as busbar).





Any numbers of poles conductor bar can be installed vertically or horizontally, on straight or curved system. This single pole conductor bar system can be used outdoor with a protective cover which is antioxidant, UV resistant, impact resistant. For high temperature environment (-40 ~ 115℃), the protective cover is available with different sizes for different sized conductor bar. Besides, we supply the full set conductor system, including conductor bar, protective cover, jointing material, feed sets, end caps, hangers, expansion section, Current Collector, tow arm, support bracket, isolation section, etc.



Weihua also provides curved conductor bar with R≥1200mm. All conductor bars are approved by CCC, ISO9001 and CE.





2. Seamless Conductor Rail System
The seamless conductor rail system is without any joints within length 1000m, which is available for 3P, 4P (50A, 80A, 100A, 120A, 140A) with load matching. Meanwhile 3P, 4P can be combined into the 6P or other level. Weihua provides complete seamless conductor rail system including components such as hanger clamp, bended joints, Current Collector, towing bracket, end tensioner/feeding, towing arm, carbon brush, support bracket, etc.






The seamless conductor rail system has the features of quick and easy installation, economical and practical, stable operation, fast speed, less noise, flexible power supply, etc.

4P Conductor Data:
Rating: 4P, 660V, 50A-120A
Conductor material: copper
Insulation cover/jacket: Rigid PVC within 75℃
Color: Orange (Eye-catching warning color)



3P Conductor Data:
Rating: 3P, 660V, 50A-120A
Conductor material: copper
Insulation cover/jacket: Rigid PVC within 75℃

3. Solid Steel Conductor Rail System
The solid steel conductor rail system is an open style conductor system which is composed of a ladder type copper rod and a channel steel or a T shape copper row and a groove type aluminum. It is supported by high-strength special insulators to form a mobile sliding line that feeds lifting equipment.



The length of the conductor bar section is usually 6m and the insulation bracket installation spacing is generally 3m. This open solid conductor system is usually for large tonnage cranes. The power supply current is usually ≥800A, 1000A, 1600A, etc.

Crane Wire Rope Guide for Electric Hoist

Rope guide is also called wire rope arranging device used to make crane steel wire rope neatly arranged around the drum to avoid wire rope circles in a mess or overlaps causing malfunction to Electric Hoist, or even destroy the hoist. Crane rope guide can guarantee the normal working of electric hoist, and extend the service life of wire rope and drum.

Rope guide

1. Application: Rope guide for electric hoist wire rope guide.
2. Rope guide is also called rope arranging device.
3. Its function is to make wire rope neatly arranged around the drum, in case wire rope circles in a mess or overlaps cause malfunction to electric hoist, even destroy the hoist.
4. when rope guide is running, it gets a large lateral force. That causes brakes. Wire rope guide is the most easily damaged part of electric hoist.
5. Its interchangeability is good.

Crane Hook, casting hook, forged hook, laminated hook for hoist, overhead crane, gantry crane

Crane hooks are a part of a hoist or winch of cranes such as overhead crane and gantry crane. Weihua provides light duty hooks (cap. 0.5t - 20t), heavy duty hooks (cap. 20t - 500t), forged hooks, laminated hooks and all kinds of special-purpose hooks.

Crane hooks 

1. Application scope: Hooks for Electric hoist, winch hoist and crane.

2. Two shapes: single hook and double hook. Single hook is easy to make and convenient to use, and its lifting capacity is usually under 80t. When the lifting weight is large, double hook is a better choose for its load-bearing is symmetric.

3. Two types: casting hook and laminated hook. Laminated hook is safer, and its dead weight is larger. It's usually used to lift large weights and steel ladle.

4. Good-tenacity and high-quality carbon steel is the best material to make hook since it's good to absorb impact.

5. Hook lifting capacity is 5t to 500t.

Crane Coupling, Gear Coupling Connecting Crane Motor Reducer and Wheels

Coupling is the most commonly seen connecting components in shafting transmission for Overhead Crane and Gantry Crane. We made customized crane coupling with different size, different materials, and for different cranes.

Coupling

Pairs of Gear Coupling

1. Application scope: Connecting different mechanism such as gearbox and wheels.
2. Crane Coupling is constituted by two parts. One connects the drive shaft, another connects the driven shaft.
3. Coupling is the most used connecting components in shafting transmission of machinery.
4. There are two types: Fixed coupling and movable coupling.
5. In high-speed and heavy-load power transmission, some couplings could buffer and absorb shock to improve the dynamic performance of shafting.
