Description

FEM/DIN standard double girder overhead crane 

Capacity can be up to 500t. 


This product is with reliable performance, flexible application range, easy to operate and convenient to maintain.

 

Lightweight and Modular Design:

1. Overall height is 20%~25% lower than traditional cranes;

2. Self-weight is lighter by 20%~30%;

3. Max wheel load reduces 15%~20%;

4. Smaller limiting size increases working scope;

5. Light structure reduces the cost of workshops;

6. Every component designed to be a standard series and interchangeable

8. Standard modular design makes it easy to manufacture the standard quality products.

 

Advanced Manufacturing Technology: 

1. Sandblast pretreatment on steel plates and the surface quality reaches Sa2.5;

2. CNC cutting machine cuts webs plate to insure the curved surface is smooth and accurate;

3. Seams are soldered by automatic arc welding and detected by ultrasonic and X-ray ;

4. The structure of girder and trolley is manufactured by floor-type boring lathe to insure flatness.

 

Safety: 

1. Safety supervision system is with an overload limiter and shows the load value on screen to warn operator to avoid overload;

2. Before start up, the whole system will carry out self-checking includes: power supply voltage, default phase, validity of the safe protection device and the zero button;


High Reliability: 

1. Use imported motor with insulation grade of F and protection degree of IP54. With overheat alarm. The motor is shielded by aluminum alloy stretching cover with good heat dissipation performance;
