JPH0710165A - Bottom divided type conveyance tool - Google Patents

Abstract

PURPOSE:To prevent a package from being pulled out together with a bottom cloth or the shape of a freight from being deformed when the two divided bottom cloths are pulled out by pulling up hooking means connected to side cloths by laminating and providing a high slidable sliding member capable of being divided on the bottom cloth upper surface on which the freight is placed. CONSTITUTION:A bottom cloth 11 is a square, and a square side cloth 12 is connected to one end side 11' of this bottom cloth 11. And a bottom part belt 15 serving as a loop-shaped pulling-out hanging belt is provided on an end edge 12' on the opposite side of the bottom cloth 11 in the side cloth 12. The bottom part belt 15 is hooked to a hook of a crane in unloading, so as to be used to pull out main bodies A, B. Moreover binding cords 16, 16' are used likewise as the conventional conveyance tool. The high slidable sliding member may be piled up on the whole surface or a partial part of the upper surfaces 11A, 11B by forming the boundary of a dividing line C of the bottom cloth, but it is preferred to pile up it on the whole surface of the bottom cloth in the sense that the contact surface of the bottom cloth 11 to the freight like a bag-like article to be placed thereon is decreased.

High-density polyethylene is preferable because it is inexpensive and has good slidability. In addition, the form in which the layer is equipped is flexible in that a film, a woven fabric, or a non-woven fabric is flexible, which is convenient when collecting the carrier. It is more preferable to use a high-density polyethylene woven fabric, for example, a fabric known by the trade name such as “Tarpicloth”. It is desirable to use these highly slipping sliding materials which generally have a difference in friction coefficient with the cargo of 0.1 or more, preferably 0.3 to 0.5. It is selected as appropriate depending on the slipperiness of the cargo to be placed and the packing style.
