    • A lift system 10 includes a cylinder 58 having an end surface, a threaded member 76 supported for movement with a piston 80, and a nut 50 threadedly engaging the threaded member and selectively engageable with the end surface. Engagement of the nut and the end surface limits axial movement of the piston relative to the cylinder in at least one direction. A drive mechanism rotates the nut relative to the threaded member, and a control valve controls movement of the piston relative to the cylinder. A drive control mechanism controls operation of the drive mechanism and rotation of the nut. A nut sensor 264, 268 senses a portion of the nut. The nut sensor is in communication with at least one of the control valve and the drive control mechanism. When the nut sensor detects a portion of the nut, the control valve stops movement of the piston or the drive control mechanism stops rotation of the nut.
    • 提升系统包括具有端面的圆柱体,被支撑用于与活塞一起移动的螺纹构件以及与螺纹构件螺纹接合并且可选择性地与端面接合的螺母。 螺母和端面的接合限制了活塞相对于缸体在至少一个方向上的轴向运动。 驱动机构使螺母相对于螺纹构件旋转,并且控制阀控制活塞相对于汽缸的运动。 驱动控制机构控制驱动机构的操作和螺母的旋转。 螺母传感器感测螺母的一部分。 螺母传感器与控制阀和驱动控制机构中的至少一个连通。 当螺母传感器检测到螺母的一部分时,控制阀停止活塞的运动或者驱动控制机构停止螺母的旋转。

    • Electromechanical lifting system (100, 200, 300, 500) of a load comprising:
      - At least one cylinder (1, 21, 301) comprising a screw (2, 22, 32, 502) connected to the load and configured for descent and ascent translating along its vertical axis Y;
      - At least one electric motor (3, 23, 33) connected to one extreme portion of the cylinder (1, 21, 301);
      - Means (4, 24, 34) for transferring the rotational motion imparted by the electric motor (3, 23, 33) into translatory motion of the screw (2, 22, 32, 502).
      The cylinder (1, 21, 301) comprises a tank (1b, 21b, 301b) filled with a compressible gas and mobile compression means (5, 25, 305) interconnected with one end (2b, 22b, 32b, 502b) of the screw (2, 22, 32, 502) and configured to transfer energy from the vertical translatory motion of the screw (2, 22, 32, 502), when directed towards the tank (1b, 21b, 301b), to the gas accumulating the energy and for transferring the energy from the gas to the vertical translatory motion of the screw (2, 22, 32, 502) when directed in the opposite direction.
