PURPOSE:To surely hold a heavy load, by horizontally moving block members along a guide shaft. CONSTITUTION:In a running attitude in which a bottom face of a main beam 4' of a load case 4 is joined to the upper face of a bearing wood 3, bottom surfaces of block members 10, 10 are joined to upper surfaces of supporting plates 13, 13 and upper surfaces of the members 10, 10 corresponding to the bottom face of a floor plate 4'' to store the members 10, 10. While the case 4 is lifted by a lift device 6 to a suitable height, under this condition if one member 10 is horizontally moved to the outside and placed on the upper face of a subframe 2, the other block 10 is also positioned on the other subframe 2 by the movement of a connecting link 14. And then if the case 4 is lowered a little, the upper surfaces of each member 10, 10 are adapted to the bottom face of the beam 4' of the case 4 to hold the case 4. |
