Abstract: The present invention utilizes a hoist drum with a three different drum sections, two cylindrical and one tapered, upon which the different ends of a lifting cable simultaneously spool on and off of as a function of counterclockwise and clockwise cable spooling. This combination reduces the amount of shaft torque required to raise or lower a load while increasing the number of hoist drum rotations required to raise or lower that load. These two features are incorporated into the operation of a main crane cable length adjusting device since they offer precise and rapid adjustment capabilities to be made with smaller sized electric motors and clutches.

Abstract: A wire rope reeving support system for a cargo container handling crane having a transport trolley mounted for reciprocation along a horizontal gantry thereof and having a wire rope load hoisting system for the transport trolley wherein a mechanism is provided mid span of said gantry for supporting the wire ropes of at least the load hoisting system and permitting the transport trolley to actuate the rope system to let the trolley pass there by without mechanical interference.

Abstract: The invention relates to an arrangement for placing crane mechanisms, the crane comprising lifting mechanisms (1) with lifting drums (2), lifting ropes (3) in the lifting drums, a lifting trolley (4), a loading element (5) suspended from the lifting trolley (4) by the lifting ropes (3), four auxiliary mechanisms (10) controlling the swaying and twisting of the loading element (5) and the load (9) fastened to it, auxiliary ropes (12) in the rope drums (11) of the auxiliary mechanisms (10), and turning sheaves (13) of the auxiliary ropes (12) in the loading element (5). The lifting mechanisms (1) and lifting drums (2) are fixed to the frame of the crane, the auxiliary mechanisms (10) with their rope drums (11) are located in the lifting trolley (4), and the auxiliary ropes (12) are led from the turning sheaves (13) to a storage drum (14) for the auxiliary ropes in the lifting trolley (4), the storage drum being equipped with an additional mechanism (15) that is independent of the lifting mechanisms (1).

Abstract: The present invention relates to a mechanical anti-snag device for a container crane, which comprises a main driving unit 100 for driving the starting terminals of ropes 104; auxiliary drums 202 respectively for winding the end terminals of said respective ropes 104; torque limiters 203, one end of which is installed respectively along the rotational shaft of said auxiliary drum 202; and auxiliary motors 301, each of which is connected to the rotational shaft of the other end of said torque limiter 203 respectively, wherein said ropes 104, between said main driving unit 100 and the auxiliary drums 20, are made to pass there through while holding up the corners of the head block 107 of the container crane. During the normal transportation of containers, the shaft of said auxiliary motor respectively is firmly fixed in place, and only when there is a need for controlling the trim, list and skew of the head block 107, the fixation as such is released.

Abstract: A crane system for carrying a load while suspending it from a portal-shaped body frame via wire ropes includes first and second wire ropes on both sides, in a right-and-left direction, of an upper portion of the body frame for fixing the suspended load, and means for taking up and paying out the first and second wire ropes. The system also includes means for winding the first and second wire ropes in opposite directions, or winding them in the same direction. The first and second wire ropes may be looped together with the means of taking up and paying out the wire ropes. Connection points or sheaves may be provided on the suspended load. It is also permissible to route the first and second wire ropes parallel to each other. Further, the above takeup and payout means may be in a tapered drum form.

Abstract: A crane arranged through its reeving system to manoeuver a load. The crane includes an upper support structure, a lower support structure arranged to carry a load and six reeving cables suspending the lower support structure from the upper support structure. Means are provided for changing the effective length between the upper and lower support structure of selective ones of the reeving cables. The reeving cables are arranged such that they are connected geometrically to the upper and lower support structures at apexes of an upper and a lower quadrilateral plane figure, respectively. The reeving cables are arranged such that the cables of a first pair of the reeving cables converge in a downward direction, the cables of a second pair of the reeving cables converge in an upward direction, and the cables of the third pair of reeving cables extend between opposite ends of the first and second pair reeving cables at the upper and lower support structures.

Abstract: A palletizing apparatus has a horizontally displaceable carriage movable on a horizontal member of a frame. A counter-weight is received in one or each of a pair of uprights and is connected via a cogged belt to the lifting slider which is provided with a deflecting roll or pulley about which the belt passes. The support member or lift slider carries the pickup head. The drive for the horizontal movement of the carriage thus does not have to displace the counterweight or counterweights which are provided to balance the weight of the lifting slider and the load.

Abstract: 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.
