Abstract

Mine dump truck is an important equipment for mine transportation, and the stability of its hydraulic lifting system is directly related to the production efficiency. This study analyzes the common faults of the hydraulic lifting system of the dump truck, including the hydraulic pump without oil absorption, the lifting cylinder without cargo force, the hydraulic valve wear, etc. The corresponding elimination methods are proposed, such as regularly replacing the hydraulic oil, keeping the hydraulic system clean, and regularly checking the hydraulic valve. Detailed analysis of common faults in the hydraulic lifting system provides effective technical support for timely and accurate troubleshooting in practical work. At the same time, effective suggestions are put forward for the maintenance of the hydraulic system to ensure the stable operation of the hydraulic lifting system of the mine dump truck. The results of this study are of great practical value for improving the use efficiency of mine dump trucks and ensuring the safety and efficiency of mine transportation.
