FEM/DIN Double Girder Bridge Crane with Hoist Trolley

This double girder bridge crane is designed and manufactured with European FEM/DIN standard. And the lifting mechanism is a FEM/DIN standard hoist trolley with Max. lifting capacity 800t. The trolley is installed between two main girders. Thus it increases the traveling scope of spreader. This product is with reliable performance, flexible application range, easy to operate and convenient to maintain.

Lightweight and Modular Design:

1. Crane height is 20%~25% lower than that of traditional cranes;

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

3. Max. wheel load reduces 15%~20%;

4. Smaller size increases working space;

5. Light structure reduces the investment of workshops;

6. Every component accessory is designed with standard series and interchangeable;

7. Modularization design makes it easy for transport;

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

Advanced Manufacturing Technology:

1. Sandblast pretreatment of steel plates makes surface quality reach Sa2.5;

2. Webs plate cut by CNC cutting machine to insure smooth and accurate curved surface;

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

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

Safety:

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

2. Before starting 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. Adopt imported motors with insulation grade of F and protection degree of IP54. With overheat alarm, the motor is shielded by aluminum alloy stretching cap with good heat dissipation performance;

2. Imported reducer from Germany. Hardened gears with big bearing capacity, excellent seal without penetration of grease;

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

4. Crane wheels are forged by 65mn alloy steel with features of wear-proof, anti-fatigue and long lasting life.

5. Low energy consumption and maintenance-free;

6. Whole crane energy saving about 30%;

7. All-in-one transmission mechanism making this crane work more efficient;

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

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