Product Description

Construction double speed MD electric hoist

Advantages of MD electric hoist

MD electric hoist has the characteristics of compact structure, light weight, small size and convenient operation. It can be installed separately on the overhead crane, or it can be installed on electric or manual single crane, double beam bridge crane, cantilever, gantry crane and Other cranes. In fine work, when the lifting speed of CD electric hoist can not meet the requirements, MD type double speed electric hoist should be selected. The double speed of the MD is generally used for the precise positioning of heavy objects, and the other normal speed is used for normal lifting.

Double speed: There is an accelerating motor connected to the main motor conveyor belt next to the main hoisting motor. When the main motor rotates, this motor rotates faster than the main motor to reach the lift.
