CONSTRUCTION
The drive system consists of (4) "TMA" synchronized lifting columns which can be elevated and
lowered by means of control box and associated control switch with LED height readout (in
inches).
LIFTING COLUMNS
The TMA are electrical linear drives in no-clearance aluminum guide tubes. Surfaces of vertical
lift columns are anodized aluminum. A 24 V-DC motor drives through a worm drive and
threaded rod. A tapped nut, which is firmly attached to the push drive, moves up and down the
threaded rod and this provides the forward movement. Extension and contraction of the
telescopic tubes is by means of changing the direction of the rotation of the motor.
CONTROL BOX
The control and supply of the lifting columns is by means of an associated micro-processor
control unit IE.
(4) Column system control unit ... LD-014 Control box is double insulated for safety.
