MDItype electric hoists have fast and slow lifting speeds which make it lift steadily and accurately.
MDItype wire-rope electric hoists can be widely used to hoist heavy objects, or installed on the straight or curve I-steel beam of Single-girder Cranes. They can also be used together with Electric Hoist Double-girder, gantry crane and slewing cranes. All the above has made the electric hoists common in industrial and ore enterprises, railway, wharfs and warehouses.
