Linear movement producing device for use in e.g. lift in construction engineering, has shafts with gear wheels, and upper frame and lower frame with holes such that different equipments are connected next to each other between frames

摘要

The device has two single-arm levers (3) mounted parallelly at shafts (7, 8, 10, 11) and arranged between a lower frame (1) and an upper frame (2). One of the shafts (7) has a flange for contacting with a turning sleeve, and bevel gears connect the shafts with each other in pairs. A bearing fastens the shafts at the frames in pairs, where the lower frame has vertical supports that contact with the upper frame. Two of the shafts (7, 10) have similar gear wheels, and the frames have holes such that different equipments are connected next to each other between the frames.
