DMD / DMA Lifting Columns

DMD / DMA Lifting Columns

DMD and DMA lifting columns are self-supporting, height adjustable units designed for a variety of industrial applications such as work tables, conveyors, loaders/unloaders, and many others. 

This height adjustment capability especially serves work environments that need to meet specific ergonomic requirements for a wide range of operator positions. 

Rugged and robust, these columns provide high load torque capability in an extruded anodized aluminum, self-supporting frame.  Incorporated into the design are Thomson's Electrak actuator units in both acme and ball screw versions. 

Mid and end of stroke protections include an overload clutch along a T-slot groove design throughout the entire column profile.
