  • Patent number: 9746011
    Abstract: A beam clamp, including a clamp body having a rectangular shape symmetrically bent and butt-jointed by a plate material is described. On one side of the body housing a butt seam is a butt-joint face, and clamping jaws are protruded on the two sides of the body at the two sides of the butt-joint face. A clamping plate face is convexly disposed on one side of the body opposite the butt-joint face, and a screw hole corresponding to the clamping jaw is bored on the plate face. The screw hole is tapped and a bolt is disposed therein. The bolt and jaws form three-point clamping, providing high fastening performance. Corresponding threaded rod holes are bored on the plate face and butt-joint face and tapped. The resulting clamp has high processing precision, efficiency, and adaptability; the structure strength is high; load performance is good; and the size is small.

  • Patent number: 7997207
    Abstract: A joint connector for the lower flanges of adjoining running rails is assembled from two abutment pieces that each is seated in a lower flange of a respective rail that forms the joint. By use of centering devices, the correctly aligned positioning of the two abutment pieces is assured, wherein the abutment pieces transfer their aligned positioning to the lower flanges that meet each other without offset at the joint and the positioning cannot be negatively affected by transverse forces. The connection also provides a positive-fit in a transverse direction of the rails. Another joint connector arrangement connects the two running rails in the region of the top side. Abutment pieces in this case are seated as riders on a support rib and are connected to each other by tension rods.

    Abstract: An improved bypass device for a fall arrest system that is not impeded by cable supports as it is pulled along a flexible and/or rigid cable. The bypass device has a gate which can be quickly and easily removed from a frame of the bypass device to reveal an opening which allows the bypass device to be positioned on the cable. Once the bypass device is positioned on the cable, the gate may be reattached to the frame to partially close the opening. A portion of the opening remains unblocked by the gate so that the bypass device will pass over one or more cable supports when it is pulled along the cable. The cable supports act to guide the cable along a desired workpath. The supports are also constructed to withstand the force exerted on the cable in the event someone or something connected to the bypass device falls.

  • Patent number: 5799581
    Abstract: An articulating suspension for the bridge of an overhead bridge crane allows the bridge to be skewed from perpendicular to the parallel runs that support the bridge. The runs are allowed to pivot toward each other on pivot axes above and parallel with each run. End trucks that support end regions of the bridge from each run are interconnected with the bridge via suspension hangers. These are suspended on end truck pivots that are parallel with the runs and include thrust bearings that allow the bridge to skew. The bridge is suspended from the hangers on a pivot axis above and parallel with the bridge. The arrangement allows the necessary freedom of movements for skewing the bridge without making the crane wobbly or unstable.

Connecting parts are disposed between ends of adjacent supports, the hollow section having at least one profiled section in the shape of a square standing on a point. A square tube connects the ends and bridges the connecting parts and are inserted into the profiled sections at the ends of adjacent supports. Tie rods connect the ends of the adjacent supoorts. At least one L-shaped angle iron is disposed on each of the top sides of the ends of adjacent supports. The angle irons are connected to one another via at least one screw bolt and act, on both vertical sides of the ends of adjacent supports, on the tie rods which connect the ends together.

  • Patent number: 5009168
    Abstract: A track expanding device is employed in a conveyorized transport system to spread apart adjacently disposed sections of track thereby tensioning an endless chain travelling with these track sections. The expanding device comprises a splice and an expander having a threaded member for engaging with the splice with each of the splice and the expander being connected to an associated one of the adjacently disposed track sections thereby tensioning the endless chain as the threaded member is rotated.

  • Patent number: 4947758
    Abstract: A chain is used in an automated transport system to propel free travelling trolleys riding along a rail toward designated workstations, the chain runs within a U-shaped recess in a track channel on wheels rotatably supported by axles carried by individual links of the chain. The wheels are formed from a self-lubricating material and the axle carried by each of the links of the chain have finished outer surfaces thereby substantially enhancing the pressure-velocity value of the chain so that the chain may be run at velocities greatly in excess of those velocities presently achieved by known chains used in such automated transport systems.

  • Patent number: 4928602
    Abstract: A track clamp assembly for supporting or splicing tracks of I-shaped cross-section formed by a vertical web with horizontal parallel flanges at the opposite ends of the web and having a pair of oppositely facing grooves formed in the flanges on each side of the web. The track clamp assembly comprises upper and lower clamp members respectively having upper and lower edges insertable in a pair of track grooves, and having interengageable ramp surfaces disposed between the upper and lower edges and extending obliquely thereto. Outwardly projecting tabs on the clamp members are engageable by a connecting bolt which when tightened moves the ramp surfaces into interengagement, increasing the dimension between the upper and lower edges and forcing the clamp members into locking engagement with the track.

  • Patent number: 4926754
    Abstract: A cable way for transporting suspended vehicles or cars includes a moving pulling cable and a guide element defining a long travel axis and formed at least in part as a support cable. The cable way at certain locations is adjustable in height and to both sides along the long travel axis. At the certain locations, the support cable is replaced by rigid rails. Each vehicle is supported on the guide element by a roller mechanism including a grip secured to the pulling cable with the grip connected by an articulated rocker member to travel rollers contacting the guide element. The rocker mechanism includes two guiding or steering elements pivotally displaceable relative to the long travel axis for effecting the adjustment at the certain locations. The grip generally engages the pulling cable from below and permits travel over diversion rollers located on both sides of the pulling cable.

  • Patent number: 4694531
    Abstract: A coupler for structurally joining opposing ends of overhead support rails is disclosed herein having a pair of elongated splice plates carried on opposite sides of the rail ends so as to overlap the abutment of the ends. Each splice plate of the pair is of substantially uniform cross section having a U-shaped channel section including a central, upright web terminating in transverse, parallel flanges. The upper flange is integrally formed with an upwardly extending flange parallel to but spaced apart from the upright web. Trapezoidal ribs extend externally of the channel section in parallel spaced relationship along the upper flange immediately adjacent to the web and along the web midway between the transverse flanges. Threaded bores provided in the ribs insertably receive fasteners for bearing against the respective rails. The configuration of each splice plate is conformal with the external configuration of the overhead support rails.
