摘要： PURPOSE:To increase the working efficiency, by connecting a loading carrier for a ceiling material to a mobile car provided with a working base so as to be vertically movable and installing a receiving device of the ceiling material delivered from the loading carrier, on the working base. CONSTITUTION:A loading carrier 3 loaded with a ceiling material 11 is hauled to transfer to a construction site and a working base 5 and a loading base 12 for the ceiling material are raised respectively. The uppermost ceiling material 11 stacked flat on the loading base 12 is transferred to a receiving device 25 equipped on the working base 5 by a feeder 14. A lifter 26 is shifted under the ceiling material 11 on the receiving device 25 and the ceiling material 11 is raised up to a specified fitting position by the lifter 26 to fit it by an operator. Accordingly, the ceiling material is transferred from the loading base to the lifter without lowering the working base and hence, the working efficiency is increased.

摘要： PURPOSE:To provide a material lifting device which is used in a high-place working vehicle, structured simply, can lift materials quickly and safely, and can lift the material over the level attained by elongating a cylinder to the maximum. CONSTITUTION:On a working table 5, a pair of telescopic expansion/contraction guides 9, 9 are opposingly installed, in which a free guide 9c is arranged between the outer guide 9a and inner guide 9b on each side. A placing table 11 for ceiling materisl 6 is mounted at the top of the inner guide 9b, and a cylinder 10 equipped at the top with sheaves 14, 14 is installed in the middle between the guides 9, 9. A wire rope 15 is set over the sheaves 14, 14. One end of the wire rope 15 is secured to the lower part of one of the inner guides 9b and passed under the lower part of the base plate mounting part of the cylinder body 10a via one of the sheaves 14, while the other end is attached fast to the lower part of the other inner guide 9b. Guide 9 is furnished with a sensor to emit a signal to once restrict the elongation of the cylinder 10.

摘要： PURPOSE: To easily connect a main shaft and a drilling jig to each other. CONSTITUTION: An adapter shaft 44 with a hexagonal hole 50 of the same shape as the hexagonal hole 24 of a main shaft 8 along a concentric line is connected to the shaft 8 supported so as to be axially slidable and energized downward. Also, the main shaft 8, when lowered, is detected with a contact detection sensor 72 for detecting an adapter shaft 8 and a hexagonal shaft 28. Then, the main shaft 8 is rotated by the preset angle, thereby inserting the shaft 28 in the hexagonal hole 50 of the shaft 44. Thereafter, the shaft 8 is made to ascend to pull out the shaft 28 from the hole 50, and the shaft 44 is made to part from the shaft 8. Then, the shaft 8 is made to descend, thereby inserting the shaft 28 in the hexagonal hole 24 of the shaft 8. Furthermore, pins are driven into the shaft 8 and the shaft 28 inserted therein.
