4.0 Structure a n d fun ctio n
This actuator is to be used exclusively for installation into a dy-
namic centric-compression or tensile-loaded lift.
The linear actuator consists of a motor part (3) and a linear unit
(5), connected with each other by a bayonet joint.
The actuator consists of a direct current motor with spur gear
which sets in motion a trapezoidal sliding spindle system with
shaft joint. Via the lead screw mount, the sliding spindle trans-
forms the rotation of the gear into a linear motion of the actuator
(1).
The front hinge head (4) and the rear hinge head (7) transmit the
actuator power to both sides of the application.
4.3 Construction group
description
Motor
The motor is a 12 or 24 V DC. The motor’s shaft powers a spur
gear.
The lift speed depends on the load. The motor unit is sur-
rounded by metal housing. The metal housing cannot be
opened.
Gear unit
The spur gear is directly powered by the motor shaft which
moves a trapezoidal sliding spindle.
Linear unit
The actuator extends and retracts the push tube. The linear unit
is surrounded and protected by the guiding tube. The push tube
of the actuator is connected to the spindle with a lead screw
nut.
The linear unit is connected to the motor with several screws.
These screws should not be loosened or removed.
