1.high reliability, safety, free maintenance rate;
  a) Work duty: FEM2M, M5
 b) Protection class: IP55
 c) Insulation class: F 
 d) Continuing rate: 60% ( for the high class motor)
 e) Cooling rate: 30% than normal crane
 f) Over temperature protection: 170ºC2.Compact design, small size, low self weight, low headroom3.low noise4.Power-saved. The total motor power is much lower than normal design.

Main Girder:

1. Main girder uses bias-rail box type structure, with optimized design and light dead weight. 
2. Steel material. Q235B / Q345B.
3. The cover and web plate should get surface rust removal by roller-way conveyor blasting machine before welding;this blasting machine can perform blanking, sandblasting, painting and drying.
4. The welding work of main girder should be performed on work platform (welding assembly unit). In order to avoid distortion of main beam, we adopts U-shaped welding assembly unit to assure that vertical deflection degree between the top cover plate and joint edge of stiffened plate and web plate is no more than H/200, and also effectively reduce the partial wave of web plate.

 

 

End Carriage:

1Material use Q235B/ Q355B.2It is made of rectangular steel-pipe or steel plate by welding, the finished end carriage get 1-time positioning process on numeral control machine in order to ensure dimension accuracy and fit tolerance.3Each end carriage is supplied with wheels with double-wheel rim, buffer and anti-derailing protection device.

FOR INQUIRY:

In order to offer the most suitable design solution for you, it will be great helpful if you can offer the following information to us:
1. Lifting capacity.
2. Span length.(rail center to rail center)
3. Lifting height.(hook center to ground)
4. Have you installed the rails? Do you need us to supply the rails? How long is it?
5. Power supply: Voltage.
6. Working condition: what kind of material to lift? temperature?
7. It would be much better if it is possible for you to offer the drawing photo of your workshop.
