The treatment stall has two opposite side walls (60) which are spaced from one another. A low-friction hydraulic hand pump (100) is associated with both side walls which are moved according to the operation of hydraulic hand pump, so that the distance between side walls are changed. The hand pump is operated manually, and both side walls are moved at the same time during operation of the hand pump, such that the positions of both side walls are adjustable. A power transmission cable from the hand pump is extended between the side walls. |
