Beijun Mining Truck Winter Operation: Ensuring 3-35 Ton Models Stay Productive in Sub-Zero Conditions

1. Beijun’s Winter Maintenance Program for Underground Mining Trucks: Empowering 3-35 Ton Models’ Steady Operations in Sub-Zero Weather

When underground mining tunnel temperatures drop to -15℃ or lower, regular mining trucks often run into slow startups, unresponsive hydraulics, and more downtime. To fix this common industry issue, Beijun Machinery has rolled out a winter-focused operation and maintenance (O&M) plan designed specifically for its 3-35 ton mining dump truck —including electric models. This solution goes far beyond simple anti-freezing tactics; it combines component upgrades and workflow tweaks to keep trucks running steadily for over 10 hours a day, even in harsh winter conditions.

Customized Fluids: The Bedrock of Winter Dependability
A key part of this plan is picking the right fluids for cold conditions. For small underground trucks (like the 3.5-ton electric model), Beijun uses -35℃ low-viscosity hydraulic oil. Even at -20℃, this oil keeps viscosity below 300 mm²/s—cutting lift system response time by half compared to standard oil. For 20-35 ton diesel trucks, the package includes winter-grade engine oil (meeting National IV emission standards) and -20℃ diesel fuel. It also adds 500W magnetic heating rods to fuel tanks, which melt wax buildup in 30 minutes and prevent fuel line clogging.

Battery & Electrical Systems: Fighting Cold-Induced Performance Drops
Battery performance gets extra care in cold weather. Beijun electric mining trucks (such as the BJ-4E) have a battery preheating function that activates automatically below 0℃. This keeps over 80% of battery capacity and prevents range reduction in winter. Diesel models come with engine block heaters: a 20-minute preheat using 220V warms the cylinder to 5℃, increasing startup success from 70% to 98%.

On-Site Training: Turning Plans into Real Results
On-site training for operators is another key part of the program. Beijun engineers hold 1-2 day workshops at mines, teaching the "Winter 3-Check Routine": pre-shift checks of hydraulic hose seals (prone to cracking in cold), mid-shift checks of brake temps (wet brakes must stay above -5℃), and post-shift clearing of frozen ore in cargo boxes. A coal mine in Lüliang, Shanxi, reported improvements: daily operation increased from 8.5 to 10.2 hours, and truck breakdowns dropped from 15% to 3%.

2. Beijun’s 3-35 Ton Underground Mining Trucks: Beating Winter Sluggishness
Winter brings unique hurdles: thickened fluids, drained batteries, icy tunnel floors. Beijun 3-35 ton mining dump truck, with a winter upgrade plan, are engineered to tackle these issues. Component upgrades and practical tips ensure reliability and efficiency in sub-zero mining operations.

Hydraulic System: Keeping Responsive in Cold Conditions
Hydraulics get specialized winter upgrades. Beijun swaps standard hydraulic oil for winter-grade oil in all underground models. For 10-ton trucks in narrow tunnels, this oil enables lift cylinder response in just 2 seconds at -18℃. Hoses are reinforced with cold-resistant rubber (tested to -30℃) to prevent cracking and long downtime.

Brake Safety: Reducing Risks on Icy Tunnels
Brake safety is critical on icy surfaces. Beijun’s 20-35 ton dual-axle trucks use DOT 4 low-temperature brake fluid that won’t freeze even at -40℃. Weekly moisture removal via the built-in brake tank water separator prevents ice buildup. Small 3-5 ton trucks get serrated winter tires (18mm tread depth) increasing grip by 40%, while 35-ton models can use cold-resistant rubber chains lasting over 3 months in sub-zero temps.

Electric Model Upgrades: Maintaining Range in Cold Weather
Electric models get thermal management systems maintaining battery cells between 5℃–25℃. During tests at a Shaanxi mine, the BJ-4E electric mining truck ran 8 hours straight without mid-shift charging even when tunnel temps hit -12℃.

“Winter performance isn’t about fancy tech—it’s about solving the small, daily problems that slow mines down,” says a Beijun technical manager. By focusing on fluids, brakes, and batteries, the company ensures 3-35 ton trucks stay productive, regardless of cold underground conditions.

3. Make Your Underground Operations Winter-Resilient with Beijun’s 3-35 Ton Mining Trucks

Winter underground operations present one core challenge: keeping equipment running. Beijun’s 3-35 ton mining dump trucks, supported by a special winter progra, convert sub-zero temps from a problem into an opportunity for stable output.

Fuel & Oil: Winter-Ready for Reliable Power
Beijun recommends -20℃ diesel for all diesel underground trucks, adding anti-gelling agents below -25℃. The 35-ton tri-axle model’s fuel tank has an insulated cover to retain heat. Winter-grade hydraulic oil prevents freezing and reduces wear on lift pumps, extending their lifespan by 20% versus standard oil.

Cab Design: Comfort & Safety in Winter
Truck cabs include high-efficiency heaters warming interiors to 15℃ in 10 minutes, reducing operator fatigue. Anti-fog windshields and LED lights ensure clear visibility in dim, icy tunnels.

On-Demand Support: Preparing for Winter Proactively
Beijun offers "Winter Readiness Checks," where engineers inspect cold-sensitive components (rubber seals, batteries) and perform on-site replacements. An Inner Mongolia iron ore mine saw a 25% increase in daily ore transport after using this service.

Our goal is simple: make sure our 3-35 ton trucks work just as hard in winter as in summer," says a Beijun sales director. Customized fluids, reinforced components, and on-site support help mines maintain productivity year-round.
