摘要： The hydraulic system is used to drive a hydraulic motor for operation in a quartering direction for lowering of cargo as well as for operating the drive motor in a lifting direction. The hydraulic system employs an oil-gas accumulator which accumulates pressure oil during a quartering mode of operation of the drive motor. During a subsequent lifting mode of operation of the drive motor, stored pressure oil is used for the operation of the drive motor.
摘要翻译：该液压系统用于驱动液压马达，用于在四分割方向上操作以降低货物以及在提升方向上操作驱动马达。液压系统采用油气储存器，其在驱动马达的行进作业方式下累积压力油。在驱动电动机的随后提升操作模式期间，存储的压力油用于驱动电动机的操作。

摘要： A davit device (20) is arranged suspended over an associated boat (123) onboard a ship (25) or similar vessel. Horizontally, telescopically displaceable davit arms (121, 121) can move the boat (123) from a parking position to a launching position, and vice versa, while a hoisting device (122) can move the boat (23, 123) vertically. In that the hoisting device (122) is secure to the radially innermost, axially extendable telescope part (121a, 121a) of the davit arms (121,121), the vertical and horizontal movements can be carried out independently, in a controlled way.
摘要翻译：悬挂在船舶（25）或类似船只上的相关船（123）上的吊架装置（20）。水平地，可伸缩移动的吊架臂121,121可以将船123从驻车位置移动到发射位置，反之亦然，而提升装置122能够垂直地移动船只23,223。因为起重装置（122）固定到吊架臂（121,121）的径向最内部，可轴向延伸的望远镜部分（121a，121a），垂直和水平运动可以以受控的方式独立地进行。
