Underground Loader For Mine

RL-2 Load-Haul-Dump Machine

Workhorse of small to medium size mining and tunneling projects
The trusted workhorse of miners and tunneling professionals, the RL-2 Load-Haul-Dump Machine is ideal for small to medium size rock excavation operations. The RL-2 maintains the simple yet very robust design tenets of what a mining equipment should be - it has a small footprint and turning radius suitable for small envelope sizes, high proven reliability, and straight-forward mechanical components that are easy to maintain.

The RL-2 is CE certified, complying with the essential health and safety requirements of the Directive 2006/42/EC and low voltage directive 2006/95/EC (thru compliance of EN 60204-1:2006+A1:2009)

Underground Mining  Crawler Based Mucking Shovel Loader
Introduction of Underground Mining Crawler Based Mucking Shovel Loader
Underground mining mucking loader is also called excavating loader, integrates multiple functions including excavation, conveying, loading, running, Because of its high working efficiency, strong ability to adapt the space, less polluting to the air inside of the tunnel, it becomes a very important mechanical equipment in tunnel construction.
The main action is pilot valve control, easy and convenient operation, safe and comfortable, flexible and strong climbing ability, and smooth work without impact.
Can use the work arm to achieve the risk of face-to-face, full-section rock loading, leaving no dead ends, no manual cleaning of the work surface.
