Abstract
PURPOSE: To lighten an entire telescoping mechanism and hold an elevating stand stably by winding one end of a connection means to a winding means normally/reversely rotating and driving on a car body and connecting the other end to an intermediate boom through a lower boom.
CONSTITUTION: At first, a hydraulic cylinder 21 is operated and a middle boom 10 is pushed upward by a push up bar 22 while contacting to the lower surface near the center of the middle boom 10. Then, a hydraulic motor 25 is operated and when each drum is rotated and a wire is wound, the middle boom 10 is pulled out so as to be pushed out upward than the lower boom 11 and simultaneously an upper boom 12 is slided so as to be pushed up from the upper end opening of the middle boom 10. The entire length of a telescoping boom body is lengthened gradually and the lower boom 11 is pivoted by a pivot plate 17 and as the interval is constant, the middle boom 10 is turned so as to be in X-letter shape around a connection shaft 13 and the elevating stand is lifted highly.
