Abstract

The invention discloses a liftable and movable gantry crane, which comprises a rack and a sling. The rack includes a pedestal, column located at both ends of the pedestal respectively and a crossbeam bridges the columns. Each column consists of a first column and a second column disposed on the pedestal, and the second column can do lifting sliding relative to the first column. Also mobile devices in contact with the ground are mounted at two ends or one end of the pedestal. A slide rail is disposed on the crossbeam, a sliding device is mounted on the slide rail, and the lower end of the sliding device is provided with the sling. A reinforcing bar is also arranged between the second column and the pedestal, one end of the reinforcing bar is rotatably connected to the second column, and the other end of the reinforcing bar is slidably disposed on the pedestal. The gantry crane provided by the invention has the characteristics of simple structure and strong practicability, and is liftable and movable at the same time.

Description

technical field [0001] The invention relates to the field of crane equipment, in particular to a liftable and movable gantry crane. Background technique [0002] Gantry cranes are mainly used for loading and unloading operations of outdoor cargo yards, stockyard cargo, and bulk cargo. Its metal structure is like a door-shaped frame. Two legs are installed under the main beam, which can directly walk on the track on the ground. The two ends of the main beam can have outrigger cantilever beams. The deformable gantry crane has the characteristics of high site utilization rate, large operation range, wide adaptability and strong versatility, and is widely used in port freight yards. [0003] The gantry crane mainly includes a gantry frame composed of pillars and main beams and a spreader, wherein the gantry frame includes a gantry frame composed of two columns and beams. [0004] The frame of the existing crane does not have the function of lifting, that is, some goods cannot...
