Double girder overhead(bridge)crane is composed of box type bridge frame, lifting trolley, crane traveling mechanism, and electrical system. It is rely on the bridge frame along the workshop orbital direction moving longitudinal, the trolley along the main beam direction moving transverse and the hook lifting movement to work.



The double girder bridge overhead crane introduction

The double girder bridge overhead crane with a hook, have only a set of lifting mechanism. More than 16/3.2 tons of  double girder overhead crane with two hooks, it has two independent sets of hoisting mechanism. The main hook used to lift heavy objects, the auxiliary hook lift light objects, in which the rated load range can also be used for collaborative main hook tilting or tipping the material. But must pay attention, do not allow the two hooks lift two goods at the same time. If the two hooks work together, the weight of the object will not exceed the rated lifting weight of the main hook.

Double girder bridge overhead crane allocation hook used in machining, assembly workshop, metal workshop, metallurgy and casting workshop and warehouse handling work; allocation of grab is suitable for metallurgy, cement, chemical or open fixed span in bulk material handling.Structure are as follows, Lifting motor, gearbox, drum and limit switch are integrated with compact design to save the user's working space. Apply the modular design to enhance its reliability and meanwhile to reduce effectively the cost and time for maintenance.

Hoisting mechanism is designed strictly in the relevant  FEM standards. Use below parts:

 Aluminum gearbox housing

 Smooth running, low noise

 Lifetime lubrication (in the safey using cycle)

 Magnetic disc brake
