  • Patent number: 9422138
    Abstract: An arrangement for damping oscillation of a loading member in a crane includes a trolley, a hoisting mechanism, hoisting ropes, and a loading member. The arrangement includes a vertical guide projection arranged in an upper part of the loading member, and a guide part arranged in the trolley and receiving the guide projection. Damping members connected to the guide part are arranged in a separate support frame which is guidable into its place in a dock arranged underneath the trolley and which is lowerable off the dock onto the loading member. The guide part is a floating guide tube structure. The damping members include a plurality of side damping modules connected between a side wall of the guide tube structure and the support frame for substantially damping horizontal movement of the guide tube structure. A support joint is arranged in an upper part of the support frame.

  • Patent number: 7128226
    Abstract: The invention relates to a lifting device for loads, especially to a suspension lift for vehicles or vehicle parts. Said lifting device comprises load receiving means (14) with at least one longitudinal beam (17) mounted on the load receiving means (14) and substantially aligned in the lifting and lowering direction (S). The device further comprises at least one guide element (15) mounted on the base frame (5) for laterally guiding the longitudinal beam and thus the load receiving element (14) and a lifting gear (19) for performing the lifting and lowering movement of the load receiving means (14). The aim of the invention is to provide a lifting device that facilitates an ample lifting/lowering movement of the load while considerably reducing the overall height of the lifting device. To this end, the longitudinal beam (17) is subdivided in at least two sections (17a, 17b, 17c) in the manner of a link chain.

  • Patent number: 7004338
    Abstract: An empty container store for the temporary storage of empty ISO containers, in particular in fully automatic container terminals of sea ports or river ports includes a gantry bridge crane which spans the empty container store. The gantry bridge can be moved on an elevated craneway and has a traveling crab which can be moved thereon in the longitudinal direction thereof. A vertical lifting column is fastened to the traveling crab for lifting and lowering a load receiving means for the empty container. The load receiving means includes a spreader on a spreader support which is arranged on a spreader carriage which is guided on the lifting column by rollers on a spreader support.

  • Patent number: 6976821
    Abstract: In a device for the translatory positioning of a platform (1), in particular a tool mount, with articulated rods (2a, 2?a9 of invariable length, whose first ends are hinged to he platform (1), and whose second ends are coupled with respectively independent rail-mounted slide blocks (3), wherein the coupling points (9) on the platform (1) and coupling points (11) on the sliding blocks (3) respectively do not lie on a straight line, and the articulated rods (2a, 2?a) do not run parallel to either each other or a shared plane, only three independent sliding blocks (3) and accompanying initial articulated rods (2a, 2?a) are present. In a first variant, at least one of the coupling points (11) on the sliding blocks (3) is offset relative to the rail axis (4a), and all sliding blocks (3) are arranged on the same rail (4). In a second variant, all sliding block (3) are arranged on the same side horizontally next to the space provided for postioning the platform (1), and essentially run parallel to each other.

  • Patent number: 6857529
    Abstract: A pantographic device for conveying loads in vehicle assembly lines includes a horizontal assembled drive shaft on an upper frame and with the capacity to rotate, several parallel pulleys fixed to a drive shaft, two motors acting on the opposing ends of the drive shaft providing its rotational movement, and several flat belts fixed to the pulleys of the drive shaft on one end and two a lower frame on the opposite end, so that the rotation of the drive shaft in one direction and the other determines vertical lifting and lowering of the lower frame with regard to the upper frame.

  • Patent number: 6712230
    Abstract: A device for transporting vehicles during manufacturing is disclosed that allows for upward and downward movement of the vehicle but avoids adverse longitudinal or transverse swinging. The inventive device includes a moving carriage mounted on a fixed rail, an upper frame, a lower frame moveably connected with an elevation mechanism and at least one first pair of articulated arms for stabilizing the vertical movement of the vehicle. An additional pair of articulated arms may be provided which extend and retract in a plane that is perpendicular to the first pair of articulated arms. Additional stabilizing roller elements connected to a fixed rail are provided on a lateral arm of the upper frame to prevent swinging of the upper and the lower frames of the transporting device.

  • Patent number: 6592321
    Abstract: A device for manually maneuvering a handling unit, includes a mounting structure for attachment to a handling unit which is operated through actuation of a control mechanism connected to the mounting structure. A handle frame is connectable to the mounting structure and includes a cross member and a pair of elongate grip elements detachably coupled to the axial ends of the cross member which is releasably attached to the mounting structure. The cross member and the grip elements can be selected from a plurality of cross members and grip elements of varying lengths to thereby establish a construction kit that allows construction of handle frames of varying configuration.

  • Patent number: 5934490
    Abstract: A combination engine hoist and stand for lifting and supporting an engine includes a variably oriented "H" shaped multi hinged base with frame extension capability mounted on casters and a combined hoist and stand vertical column located on the base for communicating with and supporting both a hoist and a stand via a collar disposed therebetween. The hoist includes a boom and a hoist column, the boom pivotally attached to the hoist column and the hoist column attached to the stand column via the collar. The boom is manually adjustable for length via extension elements and the boom height is adjustable by activating a hydraulic jack. A wire rope depends from the outward extending end of the boom and is manually adjustable for length by operating a winch. The boom alone or the entire hoist is removable from the stand as desired. The stand includes a stand column and a shaft that pivotally and slidably communicates with the collar on the stand column and also includes a plate for attachment to an engine.
