摘要： A crane may comprise a mast that includes a base end and a top end located opposite the base end, at least one support beam fixedly coupled to the mast adjacent the top end of the mast, a first runway beam fixedly coupled to the at least one support beam, and a second runway beam spaced from the first runway beam. In some embodiments, the first runway beam defines a first end and a second end, and the mast is located closer to the first end than the second end. The crane may also comprise a bridge movably coupled to the first runway beam and the second runway beam, a trolley movably coupled to the bridge, and a hoist coupled to the trolley. In some embodiments, the crane only comprises one mast.

摘要： The present invention relates to a crane having a multiple-piece longitudinal structural part, in particular a tower or boom, whose pieces comprise corner arms or horizontal beams which can be placed next to one another and which can be releasably connected to one another by a mortise and tenon joint, wherein the mortise and tenon joint comprises a tongue which can be plugged into a tongue receiver and which can be fixed by means of at least one crossbar which can be inserted transversely to the plug-in direction of the tongue. In accordance with the invention, the crossbar of the mortise and tenon joint can be spread apart by a spreading device such that the pieces of the longitudinal structural part to be connected can be clamped to one another by spreading apart the crossbar.

摘要： A method of transferring a crane from a tower to an adjacent elevated site, such as a building under construction. The crane is raised from the tower by an elevating frame secured at one end to the tower. A transition section is inserted between the crane and the top of the tower. A bogie with an open end on the site straddles the elevating frame and receives cross beams on each end. The crane and transition section are raised, and the bogie is centered with respect to the tower. The cross beams are positioned under the ends of the transition section to which they are then bolted. The elevating frame is lowered to transfer the full weight of the crane to the transition section, and to the bogie, which can then be moved horizontally on the site away from the tower.

摘要： A tower crane is erected from a boom assembly, first and second tower sections of different cross section, and a base in a sequence of steps in which the boom assembly is mounted on a hollow climbing section dimensioned to be received in each of the larger second tower sections and defining a cavity dimensioned to receive each of the first tower sections. One of the latter is secured on a base in upright position, and the upright section is received in the cavity of the climbing section which is then raised relative to the first section and enveloped by one of the second sections. The enveloping section is secured to the base and the raised climbing section for supporting the climbing section whereupon the first tower section may be rleased from the base, raised, and secured to the second tower section. The climbing section may then be raised relative to the first tower section to permit the installation of another second section, and the procedure repeated, until all second or larger tower sections are superimposed on each other, the one first section being ultimately attached to the topmost second section. When the climbing section is raised relative to the attached first section, another first section may be superimposed on the one first section and the procedure repeated until the slimmer portion of the tower is assembled from superimposed first sections. Ultimately, the boom assembly is attached to the topmost first tower section, and the climbing section may be removed or stored for further use on the wider, lower tower portion.

摘要： A hoist mast composed of planar structural elements each consisting of tube means and cantilever means extending therefrom. The tube means has a male member at one end, a female member at the opposite end, which members together form a bayonet catch, a fastening portion and locking means. When at the erection of a mast two tube means are assembled with the aid of the bayonet catch, the end of the cantilever means is swung into engagement with the fastening portion of another tube means and is interlocked with it, and the locking means of the tube means is swung into locking engagement with the fastening portion of a third tube means to prevent unintentional release of a cantilever means engaging the fastening portion.
