Conductor Rail System / Weihua 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.

Rope Guide / Hoist Wire Rope Guide

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 Control Handles / Pendant / Remote Control

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).
