<p>PURPOSE:To convey objects from the base end section of a vehicle side to a tip section by extending a conveyor support member, rotating it in a nearly vertical plane, and providing a flat step member at the tip section. CONSTITUTION:The rear section of a small track 1 is located toward a building, then an extension driving device and a conveyor are rotated in a nearly vertical plane by a hydraulic device 40. They are then rotated in the horizontal plane by a turn table 3, and the tip section is located above a roof. A step member 13 is rotated in a nearly vertical plane by the operation of a hydraulic cylinder 17 and arranged in a slightly inclined state. Roof tiles on the small track 1 are conveyed on the step member 13 by a conveyor belt and spread on a roof. As the work progresses, the conveyor is rotated by the turn table 3 and moved to another position.</p> |
