BJUK-12 is a compact underground truck designed specifically for narrow-vein mining conditions. It has a 12-metric-ton capacity and is highly maneuverable and quick on inclines. Here are some of its key features:
Four-wheel drive: The truck is equipped with four-wheel drive for different sizes, and double steering cylinders are used to hinge the front and rear racks.
Lateral swing mechanism: The truck's lateral swing mechanism adopts central hinged slewing bearing, which allows for smooth lateral movement.
Braking system: The truck's braking system is a three-in-one spring brake hydraulically released wet brake, working brake, parking brake, and service brake.
Carriage: The carriage is made of high-strength wear-resistant steel plate to ensure durability. It is also self-unloading, which makes it easy to load and transfer various materials or ores.
Articulated frame: The truck's articulated frame design provides a small turning radius and great flexibility in maneuvering.
High-strength structure: The truck's structure is made of welded steel construction with optimized material thicknesses. This reduces its own weight, which allows for higher overall hauling capacity and long structural lifetime.
Automatic central lubrication: The truck is equipped with an automatic central lubrication system.
Hydraulic system: The truck's full hydraulic open-center system has one gear pump. The oil flows to the dump box hydraulic system from the pump when thesteering system is not in use. The dump box is controlled by a joystick.
ROPS certification: The truck is certified according to EN ISO 3471 for Roll Over Protective Structures (ROPS), which ensures the safety of the operator in the event of a rollover.
FOPS certification: The truck is also certified according to EN ISO 3449 for Falling Object Protective Structures (FOPS), which protects the operator from falling objects in the mine.
