In SEVENCRANE automated rubber tyred gantry cranes, the positioning technology of hoist and hoist trolleys is a very important content. Under normal circumstances, the operation of large and small trucks of container gantry cranes is automatically completed by relying on positioning technology. The controller only needs to operate the equipment. The situation can be monitored by video. Unlike the final stage of the lifting operation, which requires human intervention, the automation of large and small vehicle positioning requires higher technical reliability and accuracy.

In the crane industry, semi-gantry cranes are a special type of crane that combines the designs of overhead cranes and motorized gantry cranes. A semi-gantry bridge is supported on one side by an elevated runway, just like an aerial bridge. At the other end of the bridge, the crane is supported on the legs of a semi-gantry, at the end of which trucks run on wheels or wheels with tracks on the floor. In this design, power is typically provided by a power pole and current collector assembly on the elevated runway side of the semi-gantry crane and distributed to the crane trolley via a tow system. SEVENCRANE semi-gantry cranes can be controlled via a wired suspension controller or optional crane radio remote control system.

Semi-gantry crane is suitable for lifting, transporting, loading and unloading in open-air working places such as stations, docks, warehouses, construction sites, cement product yards, machinery or structural assembly yards, power stations, etc. It is also suitable for working in indoor workshops.

The operation of semi gantry crane is very simple, which makes many users think that the hoisting operation of the crane is not technical, but this is not the case.

Semi gantry crane, as the name suggests, is a deformation of the traditional gantry crane, and it is a kind of lifting machinery equipment between bridge crane and gantry crane.

Since the first 5t cantilever semi-gantry crane independently designed by Sevencrane was put into use, all performance indicators have been good and met the design requirements.
