Secondly, the model of the two protective control cabinets of the semi-gantry crane originally placed on the bridge platform was changed, and they were moved to the driver's room at the same time, which fundamentally improved the working environment of the electrical control cabinet. The contactors in the equipment are all changed to TB type ac contactors and RC protection coil is added to ensure the safety of the device.

Some other details such as lifting steel wire rope replacement for galvanized steel wire rope, on this basis also fill the parts of the rain cover, updated the hook assembly, relaid electrical control with wire, threading pipe, do full protective measures.
In the semi gantry crane there are a lot of metal components and mechanical parts, in order to prevent the occurrence of rust, corrosion of the bad phenomenon, also take advantage of the transformation of its thorough derusting and paint, and derusting quality reached the surface sandblasting no visible grease, dirt, oxide skin, rust and paint coating.
