Crane Steel Wheel

Crane wheels are for overhead crane, gantry crane, casting cranes, bin loading cranes, slab handling cranes, steel coil clamp cranes, magnet cranes, etc. in the metallurgical plant. Crane wheel forging materials: 60#, 65Mn, 42CrMo. 

 

Features of Crane Wheels:

1. Application scope: Sustaining the overhead crane or gantry crane

2. Weihua crane wheels adopt ZG430-640 cast steel, and thermal treatment on surface.

3. Surface hardness of our crane wheels is HB 300-350, and depth of quenching is more than 20mm.

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 Brake

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

 

Crane brake

 

1. Application: Crane 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.

Crane Control Handles

 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).

Features of Wire Pendant and Wireless Handle Piece.

1. Nylon fiber shell, glass fiber, strong and durable;

2. Fixing screws, easy to install and simple;

3. Dust-proof structure, metal contact keys, feel comfortable;

4. ABS plastic body with good-looking appearance and reasonable structure.

5. Rubber cable sleeve and waterproof seal.

6. Simplified circuit for safety operation.

7. COB button.

8. Contact resistance ≤50M.

9. Mechanical life: Momentary type: press 1 million times, Emergency stop self-locking button: press 50,000 times.

10. Electric life: Emergency stop self-locking button: press 50,000 times.

11. Protection: IP65.

 

 

Joystick remote control is usually used for the control of Double Girder Overhead Crane and Gantry Crane. Different from a crane pendant control, this joystick control is U-frequency mainly with 1 or 2 joysticks to control the inverter cranes.

 

 

Features of Joystick Remote Control:

1. Anti-interference, large crystal oscillator above 100;

2. Programmable output settings, up to 16 output points;

3. Nylon-reinforced reinforced plastic case to prevent damage caused by falling and strong collision;

4. Operating distance can be 100 meters;

5. Receiver with output cable for easy and fast installation;

6. Transmitter three-stage power indicator;

7. Acceleration delay setting can be planned (making the crane run smoother);

8. Multiple security protection design: Hamming code watchdog line 32-bit non-repetitive identification code.
