Product Details

BJ40 Underground Loader: Engineered for Demanding Narrow Veins

The 4.5-ton BJ40 loader is built to conquer tight, 4x3.5m mining tunnels. Its compact frame (under 2.2m wide) and exceptional maneuverability ensure powerful performance where space is limited.

Unmatched Power in Confined Spaces

Drive productivity with the proven WEICHAI turbo engine, engineered to deliver high torque at low speeds for rapid bucket filling and consistent cycle times in heavy ore.

Durability Where It Counts

Key components are constructed to survive sustained high-demand cycles. The 400-grade steel bucket resists abrasion, while the chained heavy-duty tires defy constant wear. Below ground, the fully sealed electrical system repels moisture, and the reinforced canopy stands guard—each feature confronting underground demands directly to ensure reliable shift-to-shift operation.

ABOUT US

4.5 T Mining Loader: Agile Performance in Tight-Space Tunneling

At Beijun Machinery Industry, we design mining equipment for the harshest realities of mining—dust-choked quarries, uneven mountainous terrain, and extreme temperature swings. Our commitment to ruggedness isn’t just talk: it’s backed by ISO9001:2015 quality certification, ISO14000 environmental compliance, and ISO45001 safety standards, plus EU CE marking for global reliability. With over 20 technical patents (many focused on structural reinforcement and wear resistance) and mining safety certifications spanning UQ-6 to UQ-45 and UK-12, every machine—from crawler dumpers to mining transport vehicles—is engineered to withstand years of heavy use.
