Übrigens handelt es sich tatsächlich um "court-circuit" (pour ponter le circuit de sécurité)

Sorry, the English term is:
limit stop
http://www.linde-hydraulics.com/files/017.htm

Move the hook to a position near the upper hook position and slowly inch the hook into the upper limit stop position. The limit switch should cause the hoisting motion to stop at the upper limit of travel. If any malfunction of either the hoist brake or the limit switch is suspected, this condition should be reported to the supervisor before proceeding. The hoist limit switch should never be used as an operating control for stopping the load. It is to be considered as an emergency limit switch only.
