The motor drive unit (11) is made up of a welded tubular bar and section bar frame. It is
fitted with a series of guide rollers. It is driven by a self-acting electric gear motor (12) that
enmeshes on the rack of the vertical column (3) via a pinion,.
An emergency brake (14) starts when (in descent) the normal operating speed is
exceeded. A special ratchet gear for centrifugal force expands and activates the brake. If
the brake is enabled, a special terminal switch stops movement.
The electric power for the gear motor is supplied via a power supply cable and controls
(15) . To prevent the cable interfering with the machinery, special cable clamps (16) must
be attached every 9 m. (In windy areas at least every 6 m). The cable is gathered in a
special container
(17) placed on the base.
To make easier the loading and unloading of the deck, two ramps (8) are lowered to form
a support deck. When the ramps are opened and closed, the movement of the lift is
stopped. The lift movement is controlled via a suspended control panel
(18) that is
located to the ground or directly connected to the electric board during the assembly and
disassembly stages of the column.
Moreover, the loading deck can be turned by 90
degrees, which allows getting closer the scaffolding or
building. If the deck is not properly closed, a
purposely-designed terminal switch stops any
movement.
