Double girder overhead travelling crane mainly consists of bridge, trolley running mechanism, trolley, electrical equipment and so on. According to the different degree of frequent use, it is divided into three working levels: A5, A6 and A7. Hook overhead travelling crane manoeuvres are all done within the driver.
Lifting capacity:5~10 tonnes, 16/3.2~50/10 tonnes, 75/20~100/20 tonnes, 100/32 tonnes 125/30~250/50 tonnes, 300/40 tonnes, 350/75 tonnes, 400/80 tonnes, 600/150 tonnes
Span:10.5~31.5m, 13~31m.
Lifting height:6~22m.
Design advantages.
1. The first honeycomb girder design of double girder overhead travelling crane, featuring light deadweight, large load and strong wind resistance.
2. Unique steel pin coupling, not only firm and reliable, but also short assembling time.
3. Flexible rod legs, site steering can be disassembled into single pieces, easy to transport.
4. Minimum installed capacity, solving the difficulties of field construction with electricity. [1]
Folding
1). Building clearance height is low, small wheel pressure
2). Easy for Installation and maintenance;
3). Reasonable structure and strong rigidity;
4). The speed can be frequency inverter speed control,Variable speed;
5). Control method is cabin control or remote control;
6). Crane is equipped with all moving limit switch, loading limit and other standard safety devices, to promise crane work safe
7). Design and manufacture according to ISO standards;
8).The Lifting Equipment is suitable for various working places, Workshop,Factory,Yard, etc;

1. How to define the lifting capacity of crane?
- When the beam hanged with hook: lifting capacity=self weight of beam + self weight of electromagnet + weight of suspended object;
- When the moving pulley and the hanging beam are integrated: lifting capacity=self weight of electromagnet + weight of suspended object;
2. How to choose electromagnet?
- The choice of electromagnet is related to the hanging object, and the specific option needs to be determined by the shape, size, temperature and shape of the suspended object. Most of the hanging objects are bundled bar, square billet, steel plate and so on.
3. How to realize the rotating mechanism of the lower rotating electromagnetic hanging beam crane?
- The rotating mechanism adopts hanging beam with rotary support type, and three in one speed reducer motor is used to drive the lower hanging beam to realize the rotation.
4. What are the main configuration requirements of the electromagnetic hanging beam overhead crane?
- Select the hard gear reducer first, lift brake need to have manual release function, fast speed of lifting and traveling
requires, higher work efficiency; if the working level is A7, the lifting motor as far as possible to avoid the use of 6 speed.
5. What are the requirements for lifting heavy objects with hanging beams?
- When the hanging beam is used, the load center deviation is not more than 0.5m.
