In order to adapt to complicated terrain condition well service, our company develops a category of workover rig that can service without guylines. The rig incorporates a supporting system to replace the traditional guyline. Thus, it can save the time and space of guyline fixing and removing and improve the service efficiency. The no-guyilne rig is best for oil well in regions with complex terrain conditions, e.g. urban city area, desert, marsh etc.
