摘要： A stacker crane having an elevated trolley on which there is a hoist, a load member beneath the trolley is moved vertically by the hoist and is guided by a mast comprising a vertically fixed inner member projecting down from the trolley and an intermediate member telescopingly slidable on the inner member. In one locking position of a toggle element swingably carried by the intermediate member it engages an upwardly facing surface of a ledge on the load member, constraining the intermediate member to move with the load member in a lower part of the range of vertical motion of the load member; in the upper part of that range the toggle element, in an opposite locking position, engages an upwardly facing surface on a ledge on the inner member so that the latter supports the intermediate member. The position of the toggle element is controlled by a pair of latching elements carried by the intermediate member at opposite sides of the toggle element, each movable up and down relative to the intermediate member and biased up to a latching position holding the toggle element in one locking position; but each latching element can move to its latching position only when the other is out of that position. The latching elements are displaced out of their respective latching positions by a dog on each, each dog engageable with a downwardly facing surface on one of the ledges.

摘要： A grapple assembly to be used in conjunction with an overhead crane providing means for picking up and transporting a plurality of blocks of heavy material simultaneously. The grapple assembly includes an elongated horizontal frame member suspended from an overhead crane, the frame member supporting a plurality of vertically extending opposed pairs of pivotable clamping members. The clamping members are each pivotably connected to the sides of the frame member and connected to a toggle linkage drive means such that a downwardly extending portion of each pair of the clamping members can firmly grip a block of material. The toggle linkage drive means are each secured to a central drive shaft which is, in turn, connected to a hydraulically driven rack and pinion. The toggle linkage drive means are also provided with spring biasing means to lock the clamping members in clamping position such that the blocks will not be released during transfer even if the hydraulic power is cut off.

摘要： A crane for lifting and transporting a load such as a heavy metal coil. An overhead winch lifts and lowers a load carriage and the load attached thereto, and a powered wheeled trolley moves the load horizontally above a floor. Attached to the carriage is a clamp, which engages the coil through its center aperture and its periphery. The clamp has two jaws, one movable with respect to the other, the movable jaw also having a movable gripping surface that moves on an inclined surface of the movable jaw towards the fixed jar to ensure a tight wedging engagement of the load. The jaws and gripping surfaces provide a nonpowered, mechanically firm grip on the load once it has been engaged by the jaws. The coil may be lifted with the jaws when its center aperture is vertically or horizontally disposed, and the load may be placed for storage in either position as well.
摘要翻译： 用于提升和运输诸如重金属线圈的负载的起重机。 架空绞车提升并降低负载滑架和附着在其上的负载，并且动力轮式推车将负载水平地移动到地板上方。 安装在托架上的夹具是通过其中心孔及其周边与线圈接合的夹具。 夹具具有两个相对于另一个可移动的钳口，可动夹爪还具有可移动抓握表面，该可动抓握表面在可动夹爪的倾斜表面上朝向固定罐移动，以确保负载的紧密的楔入接合。 夹爪和夹紧表面一旦与夹爪接合就能在载荷上提供无力，机械牢固的抓地力。 当其中心孔垂直或水平设置时，线圈可以用钳口提升，并且负载也可以放置在任一位置上存储。

摘要： A warehouse crane comprises an elevationally positionable carriage, a shuttle guidably mounted on the carriage for transverse movement, and apparatus for moving a tote pan out of storage racks alongside either side of the crane and onto the carriage, the crane further being able to replace the tote pan in its original compartment or to place the tote pan in any other compartment in either of the storage racks. The apparatus for moving the tote pan out of a storage rack includes a pair of reversibly driven endless chain mechanisms mounted on the shuttle and a tote pan puller attached to those chain mechanisms. The puller travels in a horizontal and flat orbital path, but changes from a vertical position to a transversely outwardly inclined position as it approaches the ends of that path so that the puller may engage a tote pan handle as it moves upwardly in an inclined position.
摘要翻译： 一种仓库起重机包括一个可定位的托架，一个导向安装在滑架上用于横向运动的梭子，以及用于将托盘从起重机的任一侧移出储物架并移动到托架上的装置，起重机还能够代替 将托盘放在其原始隔间中，或将手提箱放置在任一储物架中的任何其他隔间中。 用于将容器盘从存放架移出的装置包括一对安装在梭子上的可逆驱动的环形链条机构以及连接到这些链条机构上的托盘牵引器。 牵引器在水平和平坦的轨道路径中行进，但是当它接近该路径的端部时从垂直位置变化到横向向外倾斜的位置，使得当其在倾斜位置向上移动时，牵引器可接合手柄盘手柄。
