echanical construction of Lift Table
M
EdmoLift Lift Tables comprise two or more pairs of scissor arms, with one or more hydraulic cylinders. Lifting and
lowering motions are mechanically synchronized by means of crossbeams between the arms and through the platform
and base frame. The pivot points have slide bearings. Intensive use, high speed, high load, harsh environment and
multi-shift operation may require a HD-package, i.e. stronger bearings etc. than in the standard construction.
Elevation is achieved by means of single acting cylinders, which are located between the pairs of scissor arms
to provide the lifting force.
Each cylinder has a built-in hose break valve which automatically closes when the oil flow becomes too great, e.g. in
the event of a hose break. In Lift Tables with more than two cylinders, a flow restrictor is fitted to each cylinder.
Additionally there is a flow control valve in the power pack valve block, which on leaving the factory, is set at a suitable
lowering speed of approximately 100 mm/s. Contact EdmoLift if a different lowering speed is desired.
To prevent trapping under the Lift Table there is a safety frame (trip bar) beneath the perimeter of the platform. If the
safety frame has been activated the cause must be determined and eliminated. To be able to lower again the UP-
button must be pressed momentarily, i.e. a "reset operation"
