    摘要： A pipe handler for safely handling large pipes utilized in gas and oil lines, and the like utilizes a horizontal spreader bar having a dependent lifting arm hingedly attached at each end thereof. Each of the distal ends of the lifting arms includes a pivoted lifting shoe. The spreader bar is to be suspended from a crane. A winch having a double drum is mounted to the spreader bar and powered by an electric motor. Each drum includes a cable operatively connected to a respective one of the lifting arms. Initial operation of the winch causes the arms to swing outwardly. To handle a large pipe, the crane operator positions the spreader bar over a pipe to be moved, and operates the winch to swing the lifting arms outwardly sufficiently to allow the lifting shoes to thereafter swing inwardly to insert the lifting shoes into the respective ends of the pipe. The pipe can then be hoisted and moved to a desired point.

    摘要翻译： 用于安全处理在气体和油管线中使用的大管道的管道处理器等利用具有铰链附接在其每个端部处的从属提升臂的水平吊杆。 提升臂的每个远端包括枢转的升降鞋。 吊具吊杆将从起重机悬挂起来。 具有双鼓的绞车安装在吊具杆上并由电动马达驱动。 每个滚筒包括可操作地连接到相应的一个提升臂的缆索。 绞车的初始操作使臂向外摆动。 为了处理大型管道，起重机操作人员将吊具杆定位在要移动的管道上，并且操作绞盘以使提升臂向外充分地向外摆动，以允许提升鞋此后向内摆动以将提升鞋插入到 管道。 然后可以将管道提升并移动到所需的位置。

    摘要： Tong apparatus operated oleopneumatically for lifting a submerged pipeline either directly by a frogman or by an operator on a pontoon or vessel. The apparatus includes a pair of jaws controlled by a double acting cylinder with two pistons. The cylinder has a body pivotally connected to the upper end of one jaw and has an active chamber wherein a first piston with a wide cross-section slides, while a second piston having a small crosssection is pivotally connected to the upper end of the other jaw and slides coaxially as to the first piston in a second active chamber provided by the wide cross-section of the said first piston. With the present invention small quantities of oil are used in causing the jaws to approach and to grasp and lift the pipeline. The relatively wide shifting required for approaching the jaws to the pipeline to be grasped and lifted is obtained by acting oleopneumatically into the said second active chamber against the piston having a small cross-section, which involves the use of a small quantity of oil. The pipeline grasping operation, which requires a relatively small shifting and small oil consumption, is then carried out by acting oleopneumatically into the first said active chamber against the said first piston having a wide cross-section.

    摘要： Apparatus for gripping a column of block-shaped articles such as bricks arranged in an end-to-end relationship to one another with at least some of the articles being initially spaced from one another to form at least one corresponding intermediate gap in the column. Intermediate tongues are provided for insertion into the intermediate gaps thus providing intermediate support for the gripped column. The intermediate tongues are mounted in a novel manner and cooperate with novel apparatus to provide a positive return motion to the intermediate tongues for positively, accurately and quickly positioning the tongues in proper predetermined positions when the gripper is in an open condition such that the intermediate tongues are readily insertable into the gaps of the column. Then, when the gripper is closed, the positive return force is released thus permitting the intermediate tongues to float or move as required into gripping engagement with the adjacent bricks of the column thus providing the required intermediate support.

    摘要： The grab comprises a hollow cylindrical body which is connected to a suspension and control unit and in which grappling claws are displaced simultaneously between a position of engagement with a load to be handled and a position of disengagement therefrom. Each claw is supported by two parallel metallic rods which are fastened together along their entire length or only at one end. At least one rod which is of hollow construction, is connected at one end to the exterior and at the other end to a source of control fluid. Said fluid is brought to a temperature which is different from the ambient temperature, thereby causing differential expansion of the two rods and displacement of the claws.

    摘要： Lifting apparatus for lifting, conveying and/or positioning blocks or slabs, such as blocks or slabs made of concrete, masonry, stone, brick, or similar materials, and methods of lifting, conveying and/or positioning such materials. The lifting apparatus may include two spaced block supporters that are positioned or positionable to respectively mechanically engage a block or slab to support the same mechanically. Upon biasing the two spaced block supporters, the block is engaged and its weight supported, and the block may be lifted, conveyed and/or positioned at a desired location. Unbiasing the block supporters releases the block. A plurality of lifting apparatuses may be used together, including in modular form.
