QD model double-girder bridge crane is mainly composed of bridge frame, crane traveling mechanism, trolley and electrical equipment. It is suitable for transfer, assembly, maintenance and loading and unloading of machining workshop, auxiliary workshop of metallurgical plant, warehouse, stockyard, power station, etc. operations; also suitable for production workshops in the textile industry, chemical and food industries. Its working level can be divided into light, medium and heavy according to the use frequency. The working environment temperature is -25°C-40°C, and it is forbidden to use it in the environment of flammable, explosive and corrosive media.

MG double girder gantry cranes is suitable for cranes that operate indoors or outdoors, and the lifting device is a hook. The main beam structure of the crane is a double beam gantry crane. The crane moves longitudinally on the trolley track, and the trolley moves laterally on the crane gantry and the hook lifts to realize the movement and overturning of materials. There is a set of independent lifting mechanism on the trolley. The crane consists of gantry steel structure, trolley, crane traveling mechanism, electrical system and other main parts. The crane working outdoors is also equipped with rail clamp, anchor device, anchor cable device, anemometer and other devices.

LH type hoist trolley double girder overhead crane, its lifting mechanism is a fixed wire rope electric hoist, which is installed on centralized driven double rail trolley, matched with the double beam bridge crane, it is mainly used in machinery manufacturing workshop, warehouse, stockyard, hydropower station maintenance, assembly and other places.
