To ensure the continuous and safe operation of mine hoist equipment, it is crucial to implement preventive maintenance and regular inspections. This approach helps to identify and eliminate potential hazards in time. Preventive maintenance is a system based on the characteristics of hoisting equipment, focusing on inspection, servicing, and repair at fixed intervals.
In addition to routine care, main hoist operators should also participate in planned maintenance and repair work to keep the equipment in optimal condition.
Daily maintenance includes lubrication, routine inspections, and cleaning. Regular care and scheduled repairs reduce wear on mechanical parts, extend the service life of the hoist, and create a solid foundation for future maintenance while reducing the frequency of major repairs.
Hoist inspections are divided into daily, weekly, and monthly checks, tailored to the performance, structure, working conditions, and maintenance experience of each hoist. Inspection results and repair details must be recorded in the maintenance logbook and signed by the responsible engineer.
Hoist maintenance is categorized into minor repairs, medium repairs, and major overhauls.
Planned repairs restore the equipment’s original performance, extend service life, and prevent accidents, ensuring continuous and safe operation.
Lubrication plays a key role in reducing friction and wear, extending equipment life, and ensuring safe operation. Different lubrication methods include manual oiling, splash lubrication, oil rings, forced circulation, and oil mist systems. The lubrication system must be well-maintained to ensure proper oil quality, oil pressure, circulation, and cooling.
Operators must carry out basic inspections and repairs, including
