The present invention relates to a cylinder device (1) for a hydraulic lifting device having a housing (2) and a piston rod (3) axially movable relative to the housing (2). An objective of the present invention is to reliably detect an unintended descent of a chassis in an early stage without requiring an additional installation space. A rotary element (4) is mounted on the housing (2) to be rotated and moved relative to the housing (2) and to be prevented from moving axially. The piston rod (3) includes a motion transfer element (5). The motion transfer element (5) converts an axial movement of the piston rod (3) into a rotary motion of the rotary element (4). A sensor unit (6) is attached to the housing (2) and detects a rotary motion of the rotary element (4). The present invention also relates to a hydraulic lifting device having a cylinder device (1), a chassis of a mobile device having a lifting device, and a mobile device having a chassis.

    본 발명은 하우징(2) 및 하우징(2)에 대해 축방향으로 이동가능한 피스톤 로드(3)를 갖는 유압식 리프팅 디바이스를 위한 실린더 디바이스(1)에 관한 것이다. 회전 요소(4)는 하우징(2)에 대한 회전 요소(4)의 회전 운동이 가능하고 하우징(2)에 대한 회전 요소(4)의 축방향 이동이 방지되는 방식으로 하우징(2) 상에 장착된다. 피스톤 로드(3)는 운동 전달 요소(5)를 포함하고, 운동 전달 요소(5)는 피스톤 로드(3)의 축방향 이동을 회전 요소(4)의 회전 운동으로 변환한다. 센서 유닛(6)은 하우징(2)에 부착되며, 이것은 회전 요소(4)의 회전 운동을 검출한다. 또한, 본 발명은 실린더 디바이스(1)를 갖는 유압식 리프팅 디바이스, 리프팅 디바이스을 구비한 이동식 디바이스의 섀시 및 섀시를 구비한 이동식 디바이스에 관한 것이다.
