plate
The lifting platform is mounted on a two-part
base plate 9). Each base plate features a scissor
mechanism (3), which can be raised and lowered via
hydraulic cylinders (4). Each scissor mechanism carries
a lifting table (2), which acts as the load-bearing
element.
5.8.3 Lifting
mechanism
Two hydraulic cylinders are attached to each scissor
strut. When the hydraulic cylinders extend, the scissors
move up, thereby raising the lifting table.
The synchronized movement of both sides is ensured
as follows:
The scissor struts on both sides are connected by
transverse bars (5, 6).
The two hydraulic cylinders of each scissor strut
are powered by separate hydraulic circuits. The
hydraulic cylinders in a circuit are connected in
parallel. See Fig. 4.

The access ramps help the vehicle to drive on and off
the lifting table. If required, the access ramps can be
folded up and locked in place to extend the lifting table.
