  • Patent number: 9493105
    Abstract: A rail member is supported longitudinally along both sides of the deck of a truck or trailer and includes a plurality of strap hook anchoring locations at spaced positions therein. Each anchoring location is defined by a pair of hook opening extending downwardly through an upper flange of the rail member. Cargo securing straps or chains are anchored onto the respective anchoring locations using an anchor member having an upper body portion defining a tie-down opening and a pair of lower hooks which can be hooked into the pair of hook openings of a selected anchoring location. The upper body portions spans between the two hook openings so as to prevent passage of the upper body portion through the hook openings while the cargo straps or chains remain slack.

  • Patent number: 7063023
    Abstract: A subframe 50 is connected via a vibration isolator 40 to a floor 11 of a railway car body 10, and the subframe 50 has a center pin 60 protruding downward therefrom and connected to a bogie 30. The subframe 50 is connected to a coupling device 70, and is disposed so as to come into contact with stoppers 13 on side beams 12 of the car body 10. According to this structure, since the coupling device 70 is not directly connected to the car body, there is no need to weld a rigid member to the bottom surface of the floor 11, and the railway car body can be manufactured easily. Moreover, since the subframe 50 is connected to the floor 11 via a vibration isolator, less noise is transmitted to the car body. Power is transmitted from the coupling device 70 or bogie 30 to side beams, so the structure of the car body can be simplified.

  • Patent number: 4922833
    Abstract: An end structure for a railway car, and more particularly a covered hopper railway car, is disclosed which has side sill extensions extending diagonally inwardly from the ends of the side sills to the center stub sill for transmitting substantially all of the longitudinal, horizontal loads between the center stub sill and the side sills. A generally vertically extending truss is provided between the center stub sill and the end of the car above the center stub sill so as to withstand overturning moments and vertical loads between the end of the car and the center stub sill. The side sill extensions are tapered in heightwise and widthwise relation so as to minimize weight of these members. The truss includes outer vertical members which are curved so as to blend with the side sheets of the car body thereby to optimize load transfer. Inner truss members are of a convenient rectangular cross section so as to facilitate fabrication.

  • Patent number: 4506908
    Abstract: The invention relates to load bearing beams, and has for its object the provision of such beam of high strength and hence high load carrying capacity with relatively low weight, such as would be suitable for use in vehicles. The objective is met by a construction comprising a beam-like member formed by two spaced plate-like members, each of which has an outwardly directed flange to one side and an inwardly directed flange to the other side, to be of generally Z-shaped cross-section, said two plate-like members being secured to and spaced by internal cross-members. Thus, with the outwardly and inwardly directed flanges respectively being to the same side of the plate-like members an effective box-like structure is formed within which lie the spacing internal cross-members.
