Description
2.1
Service Life
The lift has been designed and tested for 22,000 load cycles according to
DIN EN 1493. After reaching this number of cycles, or after a maximum of 10
years, the lift must be replaced by a new product or be given a general overhaul.
A general overhaul must be carried out by the manufacturer or persons
authorised by them. Load-bearing structures must be inspected and, if
necessary, other parts must be replaced according to the manufacturer's
specifications.

General Machine Description

Design and Basic Functions
The MA STAR 5.5 two post lift consists, among other components, of two
edged, welded column profiles with base plate. The base plates ensure the
columns are securely anchored to the ground. The column profile bears the
weight of the lifted vehicle, accommodating the lifting carriage on the inner
panel and the control unit on the outer panel. The cable routing on the back is
covered by plastic panels and is only interrupted by the control unit.
Each lifting carriage is guided by eight sliding blocks per horizontal surface. The
lifting carriage contains the spindle-nut package with nut breakage detection.
Two support arms are attached to each lifting carriage, which in turn each
accommodate a height-adjustable support disc. In a lowered position, the
support arms are able to pivot freely. In a raised position, toothed segments
automatically prevent the supports arms from moving.
The lift drive consists of an electric motor with an electric release brake, which
moves a Tr 40x6 spindle via a belt drive. A lifting or lowering movement is
thereby triggered via the anti-rotation secured nut in the lifting carriage
depending on the direction of rotation.
The intuitive control unit is located on the back of one, or both, column(s)
depending on the design. Power is supplied via a connector plug at the upper
end of the main column. The unit enables all functions for the safe operation of
the lift and displays all operating states and errors that occur.
Depending on the situation, a signal sound indicates errors, incorrect operation
or the reaching of the CE-defined stop height during the lowering process.
Proximity switches detect end positions, asynchronism and nut breakage.
The relevant direction button light turns off to indicate when an end position has
been reached.
