Michael Byrne Manufacturing is now offering the most powerful 60” horizontal-boring machine in the industry. The D60-1.2 MiLHD like all of our machines is designed for the severest duty imaginable. This machine puts out 1,207,000 Lbs. of thrust and 181,070 Ft-Lbs. of torque making it the most powerful 60” machine on the market.
Our machine uses a 225 HP Cat 6 cylinder 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. Also included in our gearbox is a push-pull thrust package protecting the complete drive train.
The axial piston pump supplies 54 Gpm to four 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. |
