ABSTRACT:
A device (1) that compensates the weight of a suspended load, for example a tool or welding tongs, is provided as a spring tensioner with at least one barrel (4) or supporting wire that can be reeled off a barrel (3) against the force of a spring (2). The barrel (3) is supported on a shaft (6), to which the spring (2) engages directly with its interior end or via a sheath connected to the shaft (6), while the opposite exterior end of the spring (2) is mounted to the barrel (3) at the inside. A shaft drive (7) can be activated to change the pull force at the spring (2) via the shaft (6). The spring (2) is connected to the shaft drive (7) or to a drive wheel (8) allocated thereto via a freewheel. The freewheel is embodied with a catching latch arrangement (9) which, in the blocking direction has at least three or four latches (10) that simultaneously engage the recesses or catching recesses (11) which receive them, said latches being arranged at the inside at a circular drive wheel (12) allocated to a drive wheel (8). An interior body (13) of the catching latch arrangement located inside the circular drive wheel (12) supports the latches (10) and is simultaneously a part of a slide bearing for the circular drive wheel (12) for rotation in the freewheel direction. In this way, in a small space strong forces can be transferred.
