Such as ZDS Motor for MD hoist and ZDY motor for electric hoists. 

 

motors

 

ZDS Motor: 

1. Application scope: MD Hoist

2. ZDS double speed motor cluster is a composite motor which is combined by a low speed drive device between two awl rotor three-phase asynchronous motors.

3. The high-power one is the main motor, and the low-power one is the auxiliary motor. That makes ZDS has two mode of speed: high and low.

4. ZDS is a horizontal type motor, its seat is without foot, and it utilizes cone brake.

5. It's able to start frequently.

 

 

ZDY Motor:

1. Application scope: Electric hoists

2. Conical rotor three-phase asynchronous motor.

3. Utilizing automatic brake device.

4. Applies to trolley traveling with electric hoist and crane traveling mechanism.

5. Applies to the drive device that needs small starting torque and smooth brake.

6. It's self-cooled type, and its front cover connects flange.

7. Stator: good moisture-proof performance and thermal stability, and its insulation class reaches B class.

8. Rotor: Running smoothly, small vibration.

Wire Rope Pulley / Weihua Crane

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

https://www.weihuacraneglobal.com/product/Pulley.html

 

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.

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.
