Abstract: A cylinder device for a hydraulic lifting device has a housing and a piston rod axially movable relative to the housing. A rotary element is mounted on the housing in such a way that a rotary movement of the rotary element relative to the housing is possible and an axial movement of the rotary element relative to the housing is prevented. The piston rod has a movement transmission element, wherein the movement transmission element translates an axial movement of the piston rod into a rotary movement of the rotary element. A sensor unit is attached to the housing, which detects the rotary movement of the rotary element. Furthermore, a hydraulic lifting device with such a cylinder device, a chassis of a mobile device with a lifting device and a mobile device with a chassis are provided.

Abstract: A passenger restraint device of a fairground ride passenger unit, which has a passenger space, includes a position-adjustable restraint element and a lockable hydraulic adjuster which acts on the restraint element and has a cylinder-piston unit and a hydraulic accumulator. The hydraulic accumulator and the cylinder-piston unit of the hydraulic adjuster form a structural unit in that the cylinder of the cylinder-piston unit and a cylinder of the hydraulic accumulator arranged next to and parallel to the cylinder are part of an integrated cylinder assembly. The integrated cylinder assembly has a connection block with a switching plate on an axial end face, wherein the hydraulic accumulator is configured as a single unit and is detachably mounted on the switching plate.

Abstract: A locking unit for a passenger restraint device of an amusement ride passenger unit has a cylinder-piston unit with a piston rod, a hydraulic accumulator and an electronic unit. The electronic unit has a sensor unit for monitoring the position of the piston rod. The electronic unit can be switched to a first measuring mode, wherein the piston rod is at least partially retracted. In the first measuring mode, the electronic unit detects actual positions of the piston rod over a first reference period by means of the sensor unit and compares them with a first limit position range stored in the electronic unit, the electronic unit generating a warning signal in the event of a deviation between the actual positions and the first limit position range. Furthermore, an amusement ride passenger unit includes such a locking unit and a method allows for functional testing of such a locking unit.
