Background

A gantry crane (also called a gantry crane) is a bridge crane in which a bridge is supported on a ground rail by legs at both sides. Structurally, the crane consists of a portal frame, a cart running mechanism, a hoisting trolley, an electric part and the like. Some gantry cranes have legs on one side only, and the other side is supported on a factory or a trestle to run, and are called semi-gantry cranes. The gantry crane comprises a gantry upper bridge (comprising a main beam and an end beam), supporting legs, a lower cross beam and the like. In order to enlarge the operation range of the crane, the main beam can extend out of the supporting legs to one side or two sides to form a cantilever. The crane can also adopt a crane trolley with an arm support, and the operation range of the crane is expanded through the pitching and the rotating of the arm support.

At present, most of existing gantry cranes are installed outdoors, so that the enhancement of wind-proof and skid-proof safety of the gantry cranes is important, but in recent years, the gantry cranes are blown over by wind, and most of the reasons are that when strong wind comes, the gantry cranes are blown and overturn at the tail end of a track due to the fact that the gantry cranes touch a stop. Therefore, how to prevent the gantry crane from being scraped is additionally important when the large wind comes, and the existing gantry crane has the problem of poor fixing effect.
