The rope free workover rig is a small workover machine developed based on the characteristics of a large number of shallow wells and a short operation cycle in oil fields. It does not require the installation of wind-driven ropes, and other ropes are installed on its own support, without the need for anchor fixation, greatly improving the efficiency of disassembly and transportation. It can operate in environments with adjusted working conditions of wind speed (12 level 60KN) and maximum working conditions of wind speed (8 level 35kN), and is suitable for most shallow well operating environments in oil fields. The unique anti rollover and anti rollover devices, as well as the anti tilt display device, ensure safety and stability during operation. The technology of rope free workover rig is suitable for small and medium-sized models such as XJ150, XJ250, XJ350, and XJ450.
