QD Model Double girder overhead Crane is applied in open warehouse or rail sideways to conduct common loading unloading and material handling works. Capacity consist of 5T, 10T, 16/3.2T, 20/5T, 32/5T, 50/10T, 75/20T, 100/20T, 100/30T, 125/32T, 160/50T, 200/50T, 250/50T, 300/40T, 350/75T, 400/80T, 450/100T, 500/100T ---900T.

QD double girder overhead travelling crane are mainly consists of Girder frame, Crane travelling device, trolley as the lifting device and electrical parts, it is divided into 2 working grade of A5 and A6 according to the use frequency. Bridge adopts box welded structure, high degree of vertical and horizontal rigidity; crane travelling mechanism adopts separate drive. It has a strong beam and a stable travelling mechanism; the emergency switch can stop any movement once any dangerous happened.

It is rely on the bridge frame along the workshop rail direction moving longitudinal, the trolley along the main beam direction moving transverse and the hook lifting movement to work. High lifting capacity of this crane is designed with two hooks that mean two independent sets of hoisting mechanism. The main hook is used to lift heavy objects while the auxiliary used to lift light objects, the auxiliary can also be used for collaborative main hook tilting or tipping the material. However, don’t use the two hooks to lift at the same time when goods weight is over the auxiliary rated capacity.

It is an excellent choice where high speeds and heavy service are required for electric overhead travelling crane. As the widely used hoisting machinery currently especially is suitable for working at warehouses and freight yard and other department it is prohibited to use the equipment in the combustible, explosive or corrosives environment.
