The present invention relates to a tilt-adjustable lifting device for a high place work platform, positioned between a fixed frame and a moving frame, the fixed frame mounted on the rear side of a vehicle or placed on the upper part of a trailer, and the moving frame vertically moving on the upper part of the fixed frame and allowing a foot plate of a worker to be placed thereon, thereby adjusting the height of the moving frame. The tilt-adjustable lifting device comprises: foldable parts; cylinders; and a pair of fixed rods. The foldable parts protrude upward from the left side and the right side of the fixed frame, respectively, to be connected to the moving frame with centers coupled by a fixing pin to form an X-shape. The cylinders are coupled to one side of the foldable parts and receive pressure from an external driving source to drive the foldable parts. The fixed rods are included inside the fixed frame in the longitudinal direction. The foldable parts and lower ends of the cylinders are inserted into the fixed rods to rotatably be coupled. A left foldable part, a right foldable part, and the moving frame can be tilted in a lateral direction due to the difference in height between the left foldable part and the right foldable part, caused as the left foldable part and the right foldable part are independently driven by each cylinder. |
