4 Ton Eco Friendly Hauler for Underground Mining Buy
Zero Emissions & Eco-Friendly: Fully electric powertrain powered by CATL ternary lithium batteries (33 kWh), ensuring silent, fume-free operation ideal for enclosed mining spaces.
Long-Lasting Battery Performance: Provides up to 11.5 hours of runtime on flat terrain and 7.5 hours under heavy loads, with an 8-hour full recharge via AC 220V input.
Enhanced Safety and Stability: Low center of gravity, 300 mm ground clearance, and a 28° approach angle ensure safe and stable operation on uneven surfaces.
Low Operating Cost & Easy Maintenance: Electric drive reduces energy and maintenance costs significantly, offering a reliable and economical alternative to diesel trucks.
As underground mining operations face growing pressure to meet strict environmental standards and navigate complex, space-constrained workspaces, the BJ-4E Electric Mining Dump Truck emerges as a transformative solution for material transport. Blending zero-emission operation, exceptional maneuverability, and cost-effective performance, this purpose-built vehicle is redefining how mining sites balance productivity with ecological responsibility.
Designed specifically for subsurface environments—from narrow tunnels and tight corridors to enclosed mining zones—the BJ-4E features a streamlined structure that excels in limited spaces, paired with a reliable 4-ton load capacity to ensure consistent, uninterrupted material movement. At its core lies advanced CATL lithium battery technology, delivering up to 11.5 hours of continuous runtime on a single charge. This long-lasting power eliminates frequent downtime for recharging, while the truck’s fast-load handling capabilities further speed up cycle times, directly boosting daily throughput for mining teams.
Beyond efficiency, the BJ-4E prioritizes sustainability and operator well-being. Its fully electric drivetrain produces zero tailpipe emissions, drastically improving air quality in enclosed underground spaces—reducing health risks for workers and aligning with global “green mine” initiatives to minimize ecological impact. The vehicle’s compact design also enhances agility: with a tight turning radius, it navigates winding tunnels and cramped work areas with ease, avoiding the logjams common with bulkier, traditional dump trucks in confined spaces.
Maintenance is equally simplified. The BJ-4E’s minimalist engineering reduces complex mechanical components, cutting down on routine upkeep needs and lowering long-term maintenance costs. This reliability ensures fewer operational disruptions, keeping mining operations running smoothly while reducing total ownership expenses.
For mining projects that prioritize both environmental stewardship and operational agility, the BJ-4E Electric Mining Dump Truck stands as the premier choice. It doesn’t just transport material—it transforms underground mining into a more sustainable, efficient, and worker-friendly process, setting a new standard for eco-conscious mining equipment.
