hydraulic hubeinrichtung, especially zweisäulen or mehrsäulen - lift

摘要

a hydraulic hubeinrichtung has at least two distance between the at least two teleskopzylinder, together a load synchronous lifting and lowering. the teleskopzylinder are coupled together with a mechanical gleichlaufsteuerung, per teleskopzylinder a rack and pinion steering problems.in this rack and pinion steering each of the first stage of the respective teleskopzylinders).both teleskopzylinder are on the gleichlaufsteuereinrichtung in its first stage and through a respective hydraulic zwangskopplung between the first and the second stage with second stage synchronized, and in particularly simple and reliable r way.
