Roof Bolter Product Line Covers a Range of Mining Applications


Bucyrus offers three different roof bolter models for various mining conditions. Features unique to the Bucyrus RB2 series of roof bolters include fourwheel independent planetary drive and a horizontally and vertically articulated chassis frame which steers the machine and allows it to maneuver through vertical swells while helping to maintain traction by keeping all four tires on the ground. This feature also allows the user to position the machine for faster crosscut bolting.
