  • Patent number: 7540701
    Abstract: A cargo transporting box body with a cargo-handling device for cargo unloading or loading, the box body having on its bottom a floor board movable, and a movable partition wall on the floor board such that, when the movable partition wall is latched, only the floor board is movable, and when allowed to move, the movable partition wall moves in association with the floor board. A sprocket is attached around an axis at the base of the movable partition wall and driven by a reversible motor. A first chain has one end fixed to the posterior end of the of the box body and the other end to the anterior end; while a second chain has one end fixed to the posterior end of the box body and the other side the anterior end, and the first and second chains cross with each other at their mid-portions and engage with the sprocket.

  • Publication number: 20060182574
    Abstract: Provided is a cargo transportation box body with a cargo-handling device for cargo unloading or loading, the box body having on its bottom a floor board movable via a cylinder in an antero-posterior direction, and a movable partition wall on the floor board such that, when the movable partition wall is latched, only the floor board is movable, and when allowed to move, the movable partition wall moves in association with the floor board, wherein whether the movable partition wall should be moved synchronously with the floor board or with a divergence relative to the latter is securely selectable, and the movable partition wall maintains a stabilized condition, being safely prevented against lateral swinging fluctuations.

  • Patent number: 6842118
    Abstract: An overload detection device for a high-lift work vehicle is capable of detecting the load on the work platform. A base 10 of the work platform is supported with a bracket 9 at, at least, three supporting portions. Load sensors 11 each constituted of a plate member 14 and distortion gauges 15˜18 detect the extent of flexure of at least two of the supporting portions.

  • Publication number: 20030174064
    Abstract: An overload detection device for a high-lift work vehicle, capable of detecting the load on the work platform with a high degree of accuracy while adopting an inexpensive device configuration is provided. A base 10 of the work platform is supported with a bracket 9 at, at least, three supporting portions. Load sensors 11 each constituted of a plate member 14 and distortion gauges 15˜18 pasted onto the plate member 14 to detect the extent of its flexure are mounted at, at least, two of the supporting portions. The load sensors 11 are each mounted by connecting the two ends of the plate member 14 to the bracket 9 and the base 10 with bolts 22 and 25. Over the area where each load sensor is connected with either the bracket or the base 10, an elastic member such as disk springs 27˜29, which allows a displacement of the load sensor 11 relative to the bracket 9 or the base 10 along the upward direction and the downward direction is provided.
