Description:

One special purpose crane provided by our company for hydropower project management unit No.5,lifting capacity of the crane is 500T,

Span is 21m,lifting height is 35m.it has put into service now, stable service.

This crane is specially designed for maintenance of power generator. It handles very heavy load, which is not capable by ordinary overhead crane. Our design perfectly makes it fulfill stability and balance of hanging beam by synchronization of 2 trolley.

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 double trolley to synchronize lifting extreme heavy load.

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.

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.

6. Control panel: 3 ways are optional based on budget or need: Cabin with joystick panel, wireless control panel or pendent control panel.

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.

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.

Specifications:

Competitive Advantage:

1. Light self weight, low noise and few faults, generally used in normal working condition.
2. Desiged base on DIN standard from German.
3. Save the power, lower wheel load, so it can reduce the cost of support beam.
5. Adjustable speed if client request.
