The lifting spindles are accommodated in the two lift posts. The lift posts
concurrently serve as guides for the carriages. The post with motor furthermore
carries the electric driving motor and the control box. The swivel arms with
swivel arm lock and foot protection rods are mounted onto the carriages.
The threading of the lifting spindles is self-locking. The upper ends of the spindles
are designed in a way that permits to turn the spindles manually using a
crank. The cover plates at the posts protect the spindles and bearings from
dirt. The drive operates from the electric motor over V-belts onto the spindles.
The V-belt tension can be adjusted. The motor is protected by a thermal
motor protection switch housed in the control box. Its setting value is 7 A
(motor protection: IP 44). The lift is equipped with a cable-pull control system.
