Crane Cable Carrier / Weihua Crane

The crane cable carrier is used for the suspension and movement of the cables of the crane for mobile power supply, which has been widely used in various lifting machinery with the features of sturdy structure, mobile and flexible, Safe and reliable. This cable carrier can hold flat cable and round cable, running under C-rail or I-rail.

 

crane cable carrier

 

The cable carrier is device helping power supply of the crane trolley or hoist. It is composed of walking wheels, brackets, and pallets. The cable is hold on the pallet, and the traction frame is synchronized with the cable trolley to achieve the power supply for the trolley. Weihua cable carriers are divided into medium load type, heavy load type and light load type. Therefore, the wheels are Ф80, Ф63 and Ф50. And the load capacity is ≤50∽150kg. The pallet layers can be single Layer, double layer, and triple layer. The carrier at the head end is a tractor carrier, the end is a fixed cable rack, and the middle is the cable trolley.

 

 

Note:

1. After the fixed cable rack is installed, a baffle should be hung on the back;

2. Adjust the traction head so that the trolley does not touch the upper and lower edges of the traction hole during the entire travel;

3. The cable length is 1.2 times of the span of the crane and plus 8 meters.

4. Adjust the traction wire rope so that its length is less than the length of the same section of the cable. The traction wire rope is stressed during operation.

5. When the cable diameters are not equal, the cable clamps should be padded with soft rubber so that the outer diameters are basically the same in order to clamp the cables.

6. When laying cables, consider the balanced force on both sides of the cable support plate.

7. When the cable carrier has two or three layers, the requirements are the same.

8. The double washer on the carrier is an adjusting washer. When the guide rail is not suitable, put the washer on the inner side of the fixed plate to adjust the width of the gauge. It is made according to the guide rail specifications 100*68*4.5, 120*74 *5, 140*80*5, 160*88*6. Non-standard pulleys are processed according to drawings.

Crane Brake / Weihua Crane

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.

1. Application scope: Electric hoist traveling mechanism, reducers for crane.

2. Widely used in transmission equipment of mining, metallurgy, chemical industry, building material and light industry, etc.

3. The crane reducer should meet the mechanical strength needs when it's used in cranes.

4. Crane reducer mainly used in mechanism of lifting, traveling, rotating and amplitude.

5. The needs of suspension-suit-type gear reducer which is installed in traveling mechanism are small volume, light weight and compact structure; and its output end should be Internal spline which is directly installed in wheel shaft, input end should pass through a coupling and be connected with brake motor by flange; and its top should have holes for pin shaft and buffer device to fix on frame.

6. Crane motor and converter-speed-regulating motor for metallurgy are squirrel-cage rotor motor. Squirrel-cage rotor motor could meet the needs of different working conditions, such as frequent starting, braking, overload, reversing, over speed, collision and vibrating. And it also could meet the need of working under invert control, to realize soft start and four-quadrant operation.
