Description

technical field

[0001] The invention belongs to a gantry type hoisting machine (gantry crane), in particular to a stopper of a gantry crane. Background technique

[0002] Traditional gantry cranes only have brakes and no blockers. When encountering strong winds, they are easily blown by the wind and slide along the track at high speed, causing them to run off the track or fall over. Need a kind of stopper to stop the slide of gantry crane very much. Contents of the invention

[0003] The object of the present invention is to provide a stopper installed on the gantry crane to solve the problem that the gantry crane is easy to derail and slide when encountering strong wind.

[0004] The technical solution is: weld two fixing lugs on a connecting plate, fix the two splints with bolts through the fixing lugs, the upper and lower parts of the two splints pass through a connecting shaft respectively, and the connecting shaft extends out of the splint, and the upper connecting ...
