FEM/DIN double girder bridge crane with winch type trolley as cross traveling mechanism is designed and manufactured with European FEM and Germany DIN standard. Its lifting weight can reach 800t. The winch type trolley is installed between two main girders, increasing the traveling space of spreaders.

Features:

1. Lightweight and modular design makes the whole height 20%~25% lower than traditional bridge cranes;

2. Deadweight is lighter by 20%~30%;

3. Max wheel load cut back 15%~20%;

4. Smaller machine size increases working space

5. Light structure reduces the investment of workshops;

6. All components are designed of the same standard and can be interchangeable;

7. Modularization design makes it easy for shipping and transport;

8. Sandblast pretreatment for steel plates and the surface quality reaches the level of Sa2.5;

9. CNC cutting machine cuts webs plate to ensure the smooth and accurate curved surface;

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

11. The structure of girder and trolley is processed by floor-type boring lathe to insure surface flatness.

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

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

14. Brand motor is with insulation of F and protection of IP54. With overheat alarm, the motor is shielded by aluminum alloy stretching cover with good heat dissipation;

15. Germany reducer with hardened gears with good bearing capacity, excellent seal without penetration of grease;

16. Main electric components imported from international brands such as: Siemens, Schneider and ABB etc. with protection degree not lower than IP54;

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

18. Low energy consumption and maintenance free;

19. Whole crane energy saving about 30%;

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

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

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

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

24. Electrical anti-sway control realizes stable lifting and accurate positioning;

25. Advanced electric control tech makes this crane into a crane robot with semi-automatic control and full-automatic control;
