Semi Gantry crane
A gantry crane is a crane in which the bridge frame is supported on the ground rail by the legs on both sides. In structure, it is composed of mast, end carriage operating mechanism, crane trolley and control electrical parts. Some gantry cranes only have outriggers on one side, and the other side is supported on the factory building or trestle bridge. They are called semi-gantry cranes. The upper part of the gantry crane (including the main beam and end beam), outriggers, and lower beams are composed of parts. In order to expand the operating range of the crane, the main beam can extend the cantilever to one or both sides. A lifting trolley with a boom can also be used to expand the crane's operating range through the pitch and rotation of the boom.
On the basis of large-scale equipment, we designed a kind of small mobile gantry. The equipment has the advantages of light weight, high lifting efficiency, safety and convenience, etc. The equipment is equipped with 4 variable direction wheels, crane traveling by manual or electric and easy to disassemble, it is a lifting equipment that can be lifted anywhere.
