QD type double girder bridge crane, its trolley is bigger and stronger than LH type, reducer and brake separately. And this is the most important factor for working 24*7 hours per day. And this kind of heavy duty crane, it is widely used in plants, warehouses, materials stocks to lift goods or materials.
QD type crane mainly consists of two strong bridge beams, crane travelling mechanism, electric winch trolley and electric system, and could be classified into several working duties, e. G. A5, A6, A7, according to the working frequency and pure working time.
