Michael Byrne Manufacturing is now offering the most powerful 48” horizontal-boring machine in the industry. The D48-900HD like all of our machines is designed for the severest duty imaginable.
This 48” machine is also designed to do 54” bores with an optional spacer that raises the centerline while still keeping a low centerline profile. This machine puts out 900,000 Lbs. of thrust and 154,764 Ft-Lbs. of torque making it the most powerful 48” machine on the market.
Our machine uses a 173 HP Caterpillar 6 cylinder water cooled 6.6 L engine coupled to a 5-speed transmission and the exclusive Michael Byrne Manufacturing planetary gearbox. Our planetary gearbox is specifically designed for boring machines. Handling the severest shock loads, surpassing any of our competitor models.
The axial piston pump supplies 38 Gpm to three hydraulic cylinders with a max pressure of 6,000 psi. This pump also supplies the oil for the push block and optional winch.
Our tracks are connected together by heavy duty quick-disconnect track connectors. Michael Byrne designed heavy box constructed frames, for severe conditions to keep proper alignment for successful bores. This machine is a split base design for easy lifting in and out of pits.
All machine gauges and warning lights are in operators view of sight for easy operation. Also included is an emergency switch for total machine shut down. |
