Hook bridge crane is a general bridge crane which is widely used in the lifting machinery.Its lifting capacity is from 5tons to 450/80tons,and its working duty is A3~A8 according to the frequency of usage.
It is suitable for loading, unloading and hoisting work in factories, warehouses and freight yards where the ambient temperature is -20ºC~40ºC and the relative humidity is not more than 85%. It is forbidden to work in the environment of flammable, explosive and corrosive gas.
For various types of grabs, the corresponding parameters and structural types should be selected. The double-jaw grab is suitable for grabbing granular materials and powders. When grabbing materials with a particle size larger than 100mm or more solid materials, the jaw plate should be made into a belt.
