DMD /DMA Lifting Columns

Description

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 anodised aluminium, self-supporting frame.  Incorporated into the design is an Electrak actuator in both acme and ball screw versions. 

Features

  • Extruded anodised aluminium column
  • Internally restrained
  • Holding brake on ball screw units
  • Self-locking on acme units
  • Overload clutch for mid/end-of-stroke protection
  • Auto reset thermal switch motor protection
  • Safety nut on all ball screw models
  • T-slot grooves on entire profile
