BORING MACHINES

Michael Byrne Manufacturing is now offering the 24” horizontal-boring machine. The D24-115 like all of our machines is designed for the severest duty imaginable.

This machine puts out 115,000 Lbs. of thrust and 8,049 Ft-Lbs. of torque.

Our machine uses a 31 HP Water Cooled Diesel engine 3 cylinder engine coupled to a 4-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 is a thrust package protecting the complete drive train.

The gear pump supplies 14 Gpm (2 Speed 7+7) to one hydraulic cylinders with a max pressure of 3,000 psi.

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.

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.
