Abstract (en)
[origin: WO02052115A2] The invention relates to a device with at least one extension arm or support arm for multi-linked crane shaped extension arms, concrete spreader columns and similar, comprising at least one hydraulic differential cylinder for actuating a support arm. The cylinder comprises a hollow piston rod which has a tubular segment and two end pieces arranged on the ends of said segment, whereby at least one of the end pieces is welded on to the segment thereof. The welded joint is machined and the root of the weld is eliminated. At least one of the end pieces comprises a through opening which enables tool access in order to machine the hollow cavity of the hollow piston rod.
