The MH type box-type electric hoist gantry crane is used in conjunction with CD, MD and other models of electric hoists. It is a medium and small-sized crane that runs on rails. Its applicable lifting capacity is 5 to 16 tons, the applicable span is 12 to 30 meters, and the working environment is within -20 to +40 degrees Celsius.

This product is a general-purpose crane, mostly used for loading, unloading or grasping materials in open-air places and warehouses. This product is available in two forms: ground control and indoor control.

The basic structure includes: main beam, legs, lower crossbeam, electric hoist, trolley running mechanism and electrical control system. This structural form is made by welding plates into a box structure. Compared with the truss (flower) frame type hoist gantry crane, this machine is heavier in self-weight and more expensive, but the overall rigidity of the whole machine is better, and the swing during start-up and braking is small.

For large vehicle running mechanisms with a lifting capacity of less than 10 tons and a span of less than 20 meters, LD drive structures are mostly adopted; for those with a lifting capacity of over 10 tons and a span of more than 20 meters, vertical reducer drive structures are mostly used.

When operating this equipment on the ground, the running speed of the trolley is generally 20m/min, and the lifting speed refers to the standard of electric hoists. When operating from the driver's cab, a speed of 20 to 30 meters per minute is mostly selected.
