    • A work platform (48) is supported by a sleeve (46) which is movable along a tower (40) having a plurality of vertically equally spaced rungs (45). The raising system (50) of the invention comprises two hydraulic rams (52), pivotably attached to the sleeve (46) and equipped with corresponding hooks (58) at the extremity of their piston rods (52a). The rams (52) are activated simultaneously in up and down movement but in alternate directions, bearing in a hooking engagement in turn on the rungs (45) of the tower (40) to pull the sleeve (46) upwards along the tower (40). When a rung (45) is in the path of a hook (58) in the upward movement, the latter pivots backwards to clear the rung (45) and is pivoted back by means of springs (66). The lowering operation of the sleeve (46) is done similarly to the raising operation, but there is provided latch levers (82) that an operator must unlatch to allow springs (86) to pivot the hooks (58) in a rung clearing position during the retraction of the corresponding ram's piston rod (52a), so that the hook (58) will clear the rungs (45).

    • Gripper for moving heavy loads, including two hydraulic cylinders (60, 61) intended for being anchored to a support point at one end, and with their other end to be pivotably connected to a movable part (1). Two opposing cuneiform jaws (19 and 20) for gripping the load (55) between them are movably arranged on the movable part in association with pivotable rockers (6 and 7) with guide surfaces (17 and 18) for forcing or releasing the jaws against or away from the load in response to thrust or withdrawal of the rams (68, 69) of the hydraulic cylinders. The movable part is a flat base plate (1).
    • 用于移动重负载的夹具,包括用于锚固在一端的支撑点的两个液压缸(60,61),并且其另一端可枢转地连接到可动部件(1)。 用于夹紧它们之间的负载(55)的两个相对的楔形夹爪(19和20)与可转动的摇杆(6和7)相关联地可移动地布置在可移动部分上,该导向表面(17和18)用于迫使或释放夹爪 或者响应于液压缸的柱塞(68,69)的推力或退出而远离负载。 可移动部分是平的基板(1)。
