Abstract
PURPOSE: To simplify a mechanism and facilitate an assembly and maintenance by winding one end of a connection means to first/second winding means normally/reversely rotating and driving on a car body respectively and connecting the other end to an intermediate boom through a lower boom respectively.
CONSTITUTION: At first, a hydraulic cylinder 21 is operated and the lower surface near the center of the middle boom 10 is pushed up by a push up bar 22 and at the same time, hydraulic motors 25, 26 are operated and a wire is wound up by each drum. Then the middle boom 10 is pushed out upward than the lower boom 11 and simultaneously an upper boom 12 is also pushed up from the upper end opening of the middle boom. The lower boom 11 is pivoted by a pivot plate 17 respectively and as the interval is constant, the middle boom 10 is turned in X-letter shape around a connection shaft 13 and the elevating stand 6 is lifted highly and horizontally. When the hydraulic motor 25 is stopped and the hydraulic motor 26 is operated from an initial lifting motion, lower/upper booms 11, 12 are slided to A direction from the middle boom 10 and the elevating stand 6 can be moved to B direction horizontally.
