Abstract
A system for treating objects transported by at least one transport carriage and immersed into at least one treatment container, in which a treatment medium can be applied. The transport carriage comprises at least one swivel arm connected to the chassis in an articulated manner, on which swivel arm the object can be fastened. A hydraulically operating piston-cylinder unit having a first working chamber to drive the swivel arm and provide weight balancing. The first working chamber is made smaller during the downward motion of the swivel arm and is connected to a first pressure accumulator. The second working chamber of the piston-cylinder unit, made larger during the downward motion of the swivel arm, is connected to a source for pressurized hydraulic fluid and can be drained during the downward motion of the swivel arm. The pressure of the fluid in the accumulator swivels the swivel arm and object upward if the pressure in the second working chamber is sufficiently low.
