摘要:
A traveling highline aerial cable rail system for moving objects over large distances in three-dimensional space. A pair of track dollies mounted beneath substantially parallel and distantly separated support trusses allow the entire load bearing highline itself to traverse X-axis space. The highline defines the Y-axis of the system and supports a skate that moves along this axis. A platform suspended from the skate moves vertically in the Z-axis and can support extremely heavy loads depending on the gauge of the rope used in the system. A three motor pulley system with a multiplicity of sheaves allow independent movement of all three axes. The system can move objects weighing thousands of pounds stably at 60 miles per hour or more through three-dimensional space. The system can be modularly widened along the X-axis by adding truss sections, and the highline can be configured to up to 1000 feet or more, using rope that can support several tons or more. The Z-axis displacement can be multiplied via a pulley arrangement.

An apparatus is provided for the interconnection of two mobile carriages which are connected by a rigid beam and guided along parallel guide rails. The apparatus permits the simultaneous and identical movement, with respect to both direction and distance, of the carriages along the respective guide rails. The apparatus comprises two generally symmetrically disposed cables, each of which is attached at one end to an end of one rail and at its other end to a diagonally opposed end of a parallel rail. Intermediate the attachment points, the cables connect the carriages by resting on and being supported by return pulleys which are integral with the carriages. Each cable thereby describes a generally Z-shaped configuration. The Z-shaped configurations are symmetrically disposed in order to cause, during the displacement of one carriage, the tensioning of one of the cables, and thereby cause the other carriage to be identically and simultaneously displaced.

An actuation system includes a bridge crane, a trolley, and an end effector and is configured for moving a payload. A first actuator is operatively connected to the bridge crane. The bridge crane is configured for moving along an X axis in response to the first actuator being actuated. The trolley extends from the bridge crane. A second actuator is operatively connected to the trolley. The trolley is configured for moving along a Y axis in response to the second actuator being actuated. The end effector extends from the trolley and is configured for supporting a payload. A third actuator is operatively connected to the end effector. The end effector is configured for rotating about the Z axis in response to the third actuator being actuated to rotate the end effector. Each actuator is disposed in spaced relationship to the bridge crane, the trolley, and the end effector.

摘要:
A high speed cable hoist system for conventional dockside container handling cranes of the type comprising a frame and a movable boom extending laterally therefrom. The high speed cable hoist includes a hoist cable speed enhancing system which comprises a frame having a stationary sheave set positioned at the bottom thereof and a vertically movable sheave head positioned above the stationary sheave set and adapted for vertical movement within the frame. Each of a plurality of hoist cables from the conventional hoist drums extend between and wrap around two or more sheaves in each of the sheave set and sheave head, respectively, and terminate. The sheave head may be selectively actuated by suitable actuating means in order that the speed of extension or retraction of the plurality of cables by the hoist drum may be increased by motivating the sheave head either toward or away, respectively, from the stationary sheave set.
摘要:
A cable guide for the trolley traveling winch on gantry cranes for container, general-cargo, and grab operation, with a land-side support and a water-side jib that can be tilted up, the necessary deflection rollers, tensioning devices, and at least one cable drum for the trolley traveling winch. In the cable guide for moving the trolley (8), all the cables (3a, 3b) and (6a, 6b) are led from the drive drum (13) to the land-side support end and are deflected there in the deflection rollers (7a, 7b, 7c, 7d) of the tensioning device (12a, 12b). One cable pair (3a, 3b) extends to the land-side cable connection (8a, 8b) of the trolley, and the second cable pair (6a, 6b) is led to the water-side jib end (5a, 5b), and is led to the water-side cable connection (8c, 8d) of the trolley after deflection by 180.degree. . Since both cable pairs (3, 6) extend at equal cable height (9) from the top edges of the jib (1) and the support (2) of the jib (1), only a simple deflection (14a-14d) and a low cable tension path are required for deflecting the cable at the fulcrum point (11) of the jib (1) during the retraction or erection.

A single beam traveling crane includes a trolley movable over the beam and a hoist block arrangement located on opposite sides of the trolley frame. The winch which controls the hoist block cable is mounted at one end of the beam rather than on the trolley itself which in combination with the split or divided arrangement of the hoist block on the trolley eliminates any torsional effort on the beam which permits a lighter beam structure.
摘要:
The present disclosure concerns a crane, in particular a tower crane, with a jib from which a load hook can be raised and lowered via a hoisting cable, and with an electric power supply to the load hook and/or to a trolley that may be movable along the crane jib. According to the disclosure, the electric power supply to the load hook and/or to the trolley is at least partly conducted by a running cable which transmits tractive forces for the crane operation.
