125ton / 20ton / 50ton Heavy Duty Double Girder Overhead Crane For Casting usded In Steel Mill For Lifting

Applications:

This kind of crane is mainly used in BOF bay, EAF bay and CCP bay in steel smelting shop.

Description:

Normally there are four beams and two trolleys assembled on the crane, laminated ladle hook is equipped under the main trolley for lifting the ladle, and Aux trolley is for overturning the ladle and other auxiliary handing. The electrical equipment is installed inside of the main girder with heat insulation device and cooling device, the crane can work efficiently under difficult conditions such as high temperature and excessive dust condition.

Features:

1. Material: All compression structural part of crane’s components chosen material with fine quality and meet regulation. The important material has quality guarantee and inspection report.

2. Welding: In view of important welding seam and stress is more than tension weld of 70% allowance stress, conducting fault detection check and take out 5% weld length by ultrasonic test. Inspection report provided to user.

3. Trolley: Special designed trolley to lift extreme heavy and hot melted steel. Thrive to support high production output.

4. Motor: Drive motor must use China Top Brand: Jiangte Motor. Manufacturer have good achievement used and provided detailed and actual parameter prove that it is good performance product. Insulation class ≧ F; Protective class ≧ IP54. Special designed protection for high temperature.

5. Electric system: Inverter from famous brand ABB can make lifting and traveling in any speed you want specifically for your work. All mechanism is controlled by PLC. Special designed protection for high temperature.

6. Control panel: Cabin is closed type heat insulation type structure. It adopts tempering glass, equipped air-cooler, and linkage machine control structure.

7. Painting: All steel is treated by sand blasting before doing paintings. There are 3 layers of paintings. The bottom layer is zinc painting to prevent from rusting.   The color of top surface should be average. Color will not fade in high temperature.

8. Limit switch for safety: mechanical limit switch: overload limit, height limit, rail end stop limit for traveling. Electric protection: short circuit protection, lose phase protection, low-voltage protection, power failure protection, over current protection.
