Telescopic boom crane for a vehicle hired or a winch

摘要

"Telescopic boom crane for a vehicle hired or a winch.It is described a telescopic boom crane (1) for a vehicle (25) or a winch with a storage medium (6) for at least two rectangular beams (2),3) oriented to one another in the direction of the displaceable in their longitudinal axis.Which are mounted to articulate around a horizontal axis articulated (5) in the storage medium (6) and can be displaced with movement of the shuttle by means of a ServomotoR (19).For the purpose of creating structural conditions advantageous, it is proposed that the longitudinal axis of the rectangular beams (2),3) form an arc curved into a circle (4) which is also concentric to a common axis parallel to the axis of rotation (5).
