Abstract
The invention discloses a foldable gantry crane capable of ascending and descending, and belongs to the field of carrying tools. The foldable gantry crane capable of ascending and descending comprises a beam and supporting legs arranged on the two sides of the beam. Each supporting leg comprises a lifting supporting rod connected with the beam and a fixed supporting leg in telescopic fit with the lifting supporting rod, wherein a lifting mechanism is arranged between the lifting supporting rod and the fixed supporting leg. The beam is cut off from the middle, the two parts formed after cutting are hinged together, and the hinging portions are fixedly connected through a connecting plate. The two ends of the beam are connected with the upper portions of the lifting supporting rods through hinges respectively. After the connecting plate is detached, the beam can be bent downwards, and then the supporting legs on the two sides of the beam can be retracted inwards. Height adjustment can be performed as needed when the gantry crane is in use, so that use is easy and convenient. The beam can be lowered and folded when the gantry crane is not in use, so that occupied space is reduced, and transport is facilitated. The gantry crane is simple in structure, convenient to operate and low in cost.
