QE type double trolley bridge overhead crane, it is with two trolleys that works simultaneously or seperately, this crane is suitable to lift long materials, such as woods, paper tube, pipe and bar. Meantime, this type crane can be used in workshops, warehouse or outdoor stores in the factory and mines.Power supply for the main vehicle can be either through angle steel or safety slide wire. And operation can be done in the cabin(open type and close type), on the ground or through wireless remote control method.
