Hoist with a telescope-like shaped, outwardly and inwardly movable support column, disposed on a chassis and can fold down in the drive direction by pivoting about a transverse axis.

摘要

The invention relates to a mobile lifter arrangement having a plurality of concentric telescoping tubes, the outermost telescope tube being connected to an undercarriage and pivotable between raised and lowered positions by means of a lifting device which is connected to and acts upon the outermost tube. The tubes are raised and lowered by hydraulic pressure applied to only one of the tubes, telescoping motion being transmitted between the tubes by mechanical means, such as pulley and chain arrangements.
