The loader equipment management personnel lack knowledge of mechanical equipment management and have insufficient understanding of equipment maintenance and upkeep. Some better equipment has high requirements for the quality of accessories, as well as the quality of fuel, lubricating oil, and hydraulic oil. Some procurement personnel lack professional knowledge and a strong sense of responsibility, and have purchased some inferior accessories and inferior oil materials. As a result, some better mechanical equipment has suffered early damage due to the use of inferior accessories and inferior oil materials, reducing the efficiency of mechanical equipment use.

These people are not familiar with the procedures and key points of engineering machinery maintenance, and cannot keep maintenance records well.
