[0003] Existing workover rigs require the derrick to be raised and lowered to adjust its height for work. However, the derrick is prone to positional shifts during use, and small shifts are difficult to detect with the naked eye, affecting the work outcome. Therefore, it is necessary to design a workover rig derrick lifting limit protection device. Utility Model Content
