A mucking loader is essential equipment for modern mining, but many operators neglect daily maintenance, leading to reduced efficiency and a significantly shortened lifespan. One of the most critical maintenance rules is ensuring the hydraulic oil tank is filled to at least four-fifths of its capacity before operation to maintain system pressure and prevent pump cavitation.

To keep your equipment running at peak performance, follow these professional maintenance guidelines.

1. Hydraulic System Management

Before starting your mucking loader, the hydraulic oil level must reach more than four-fifths of the tank. This ensures that the pump remains fully submerged and cool during heavy operation.

Oil Changes: The first oil change should occur after 100 working hours, the second before 450 hours, and subsequent changes at least once a year.

Filter Replacement: Always replace the hydraulic oil filter element at the same time as the oil to maintain the cleanliness of the entire system.

2. General Cleanliness and Fastener Inspection

The machine should be kept complete and clean at all times. Regularly inspect all bolts, nuts, and screws throughout the chassis and working arms. If any fasteners are found to be loose, they must be tightened immediately to prevent structural damage or safety hazards during the high-vibration environment of a mine.

3. Lubrication and Greasing Protocols

Lubrication is the best defense against wear and oxidation.

Daily Greasing: Inject butter-grease into all moving parts twice a day until the grease overflows from the gaps.

Three-Day Cycle: Every three days, add lubricating oil or calcium-based grease to the connecting shafts, rotating shafts, and bearings to ensure smooth movement and prevent rust.

4. Component Inspections and Electrical Safety

Regularly check all hydraulic hoses for bends, twists, or surface damage. Damaged hoses must be replaced instantly to avoid blockages or sudden pressure losses. Additionally, before powering on, inspect cables, plugs, and sockets for damage. Ensure that circuit breakers, contactors, and indicator lights are not burnt or loose; only start the machine after verifying that the electrical system is secure.

5. Operational Best Practices

While the mucking loader is working, do not force material blocks that exceed the machine’s conveying capacity onto the belt. Overloading causes mechanical failure and unnecessary strain. Furthermore, keep electrical components away from water to prevent leakage, and clear hard objects from the crawler tracks immediately to protect the track links from damage.

6. Post-Work Care and Long-term Maintenance

After a shift, clean the machine thoroughly. Applying waste engine oil to the tracks and scraper chains will prevent oxidation and extend their service life. Every six months, perform a deep inspection of the supporting rollers, guide wheels, sprockets, and track shoes. If the bucket teeth are worn out, replace them immediately to avoid damaging the tooth seat.

Consistent upkeep is the only way to ensure your machinery remains a productive asset rather than a liability. By prioritizing mucking loader maintenance—especially monitoring hydraulic levels and lubrication—you can avoid costly repairs and ensure the safety of your underground operations. Proper care today translates to a longer machine life and higher output for your mining project.
