Overview
FEM/DIN standard double girder overhead crane is designed and manufactured with European standard. The lifting capacity of this FEM/DIN double standard overhead crane can be up to 800t. The trolley is installed between two main girders. Thus it increases the traveling scope of spreader. This crane is with reliable performance, flexible application range, easy to operate and convenient to maintain.

Product advantage

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;

7. Modularization design is easy for transporting;

8. Standard modular design makes good quality and fast delivery.
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.

High Reliability:

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.

 

Wheels are forged by 65mn alloy steel with features of wear-proof, anti-fatigue and long service life.

 

Main electric components imported from international brands such as: with protection degree not lower than IP54;

1.Whole crane energy saving about 30%;
 

2.All-in-one transmission mechanism making it work more efficient;
 

3.Variable frequency control whose high and low rotating speed ratio is 1:10 and work efficiency increases more than 20%;
 

4.Less and easy maintenance reduces the cost of maintenance;
 

5.Manufactured by advanced technology and constituted by high quality imported components greatly reducing malfunction and cost.

1. Electric anti-sway tech realize accurate positioning;
 

2. Advanced electric control tech turn it into a crane robot with semi-automatic control and full-automatic control;
