Definitions

  • a scissor lift with two separate, hydraulically operated scissor racks is for example from the Scriptures DE 29916254 U1 known.
  • Each of the two scissor racks has two parallel and co-rotating cylinder piston units.
  • Each cylinder piston unit of each unit pair serves as a command unit and is hydraulically coupled to the second, acting as a follower cylinder piston unit of the other aggregate pair.
  • Such a command / sequence arrangement or master-slave arrangement of cylinder piston units has the advantage that there are two separate hydraulic circuits, so that in case of leakage or breakage of a hydraulic line the lift still does not decrease, since the aggregates of the second, from Failure affected hydraulic circuit take over the holding function of the failed units for both scissor racks.
