Abstract: Through the design and construction of testing platform, the design of tooling and sensor, the research of testing method and process, and the on-site testing of truck-mounted drilling rig, this paper expounds the testing method of static load performance of truck-mounted drilling rig with respect to static torque and static lifting force. This method is intuitive, accurate, powerful and efficient. It replaces the method that can only obtain these two main parameters through theoretical calculation and construction experience, it provides accurate basis for the calibration, test and inspection of the two main parameters of the truck-mounted drilling rig, i.e. static torque and static lifting force.
