    摘要： A crane jib includes a support, a base arm pivoted in the support, and a jib lever pivotally connected to the base arm. The jib lever supports at its free end a work tool and is oscillated on its support by two hydraulic jacks, the first of the jacks is placed at a point from the journal place of the base arm, while the second jack is placed adjacent the jib lever. The second hydraulic jack has its line of action approximately parallel to a line through the bearing points of the base arm, while its lower bearing point is disposed at a lower level than the bearing place of the base arm.

    摘要： Freight container transfer apparatus having a pair of lifting beams mounted on support assemblies at opposite end portions of an elongated chassis for pivotal movement between opposite sides of the chassis, with spreader assemblies suspended at the outer ends of the beams for engaging the upper corners of a container, and hydraulic cylinders for swinging the beams to lift the chassis off a railroad car, highway trailer or other support (including the ground) at one side of the chassis, move it across the chassis in the space between the support assemblies and deposit it on the other side. One of the support assemblies is movable longitudinally of the chassis to accommodate different lengths of container. Hydraulically actuated stabilizer legs are engageable with the ground at each corner of the chassis to prevent overturning the chassis when the load is supported at one side, the legs being vertically adjustable to compensate for variations in ground level. Flared guide members at each end of the spreader assemblies are engageable with the corners of the container as the spreader assemblies are lowered onto the container to align them automatically with the corners of the container. Hydraulically actuated hanger links are pivotally connected between spreader assemblies and the ends of the beams to allow lateral movement of the spreader assemblies to compensate for greater lateral misalignment of the spreader assemblies with the container. Hydraulically actuated locks are provided for engagement with the corners of the container.

    摘要翻译： 货物集装箱运输装置具有一对提升梁，该对提升梁安装在细长底盘的相对端部处的支撑组件上，用于在底盘的相对侧之间枢转运动，吊架组件悬挂在梁的外端处以接合一个 集装箱和液压缸，用于摆动梁，将底盘从机架的一侧的铁路车辆，公路拖车或其他支架（包括地面）提起，将其移动到支撑组件之间的空间中的底盘上并将其放置 另一方面。 支撑组件中的一个可移动到底盘的纵向以适应不同长度的容器。 液压驱动的稳定器腿可以在底盘的每个角部与地面接合，以防止在负载被支撑在一侧时翻倒底盘，腿可垂直调节以补偿地面水平的变化。 在扩展器组件下降到容器上以使其与容器的角部自动对准时，扩展器组件的每个端部处的扩口引导构件可与容器的角部接合。 液压驱动的悬挂器连杆枢转地连接在吊架组件和梁的端部之间，以允许吊具组件的横向移动以补偿扩展器组件与容器的更大的横向不对准。 提供液压致动的锁以与容器的角部接合。

    摘要： A loading and unloading device is located at each end of a loadcarrying vehicle. Each such device consists of a pair of telescoping booms hinged together at their upper ends and hinged to the vehicle body at their lower ends, a telescoping support boom hinged to the other booms at its upper end and to the vehicle body between the booms at its lower end, a double ended lever pivotally mounted intermediate its end at the upper hinge point, and power means attached to one end thereof to cause the other end to pivot, to thereby move a load attached thereto.
