The Double Drum Hoist Winch Preventive Maintenance Program is designed to enhance preventive inspections, repairs, and systems, including maintenance intervals, content, quality standards, and development characteristics of various types of service equipment. Improvements in elevator operation and maintenance are better than traditional ones, and major equipment should also be involved in mine hoist maintenance and repair work plans. In order to ensure the safety of mine hoisting equipment, achieve continuous and safe operation, preventive measures, improve the maintenance and repair level of equipment, and find and eliminate accidents.
