摘要： The positioning device comprises a chassis (1) provided with a drive wheel (2), mounted on the shaft of a motor (6), and a reversing wheel (3). The positioning device further comprises a loop-shaped traction member (4) tensioned around the wheels (2, 3). The traction member (4) is connected to a load (5), which is movable relative to the chassis (1) and together with the traction member (4) forms a closed loop. The drive wheel (2) and the motor (6) form a drive means for driving the load (5) via a first section (41) of the traction member (4), which first section is disposed between the load (5) and the drive wheel (2), and via a second section (42) of the traction member (4), which second section is disposed between the load (5) and the drive wheel (2). The load (5) carries tensioning means (7) for tensioning the traction member (4). These tensioning means act on the first section (41) of the traction member (4) via a first point of engagement (A) and on the second section (42) of the traction member (4) via a second point of engagement (B). These tensioning means (7) keep the traction member (4) under tension. The load (5) is coupled to the traction member (4) via a coupling mechanism (8). The coupling mechanism (8) links a first relative movement of the first point of engagement (A) relative to the load to a second relative movement of the point of engagement (B) relative to the load in an opposite direction.
