Pipe lifter with device for horizontal position balancing. The device includes an angle arm 6, one end of which is swingably-joined with a bearing at an upper horizontal shank 2 on the pipe lifter 1. The other end is equipped with a lifting eye 5. Alongside of the angle arm 6 there is a pressure bar 9 axially extendable against the effect of at least one pressure coil 11. The angle arm 6 can be swung out from an inactive position to a position with the pressure bar 9 in stop contact with the upper shank 2 and thereafter, can be further swung out to load lifting position, against the effect of pressure coil 11. <IMAGE> |
