Michael Byrne Manufacturing is now offering the most powerful 36” horizontal-boring machine in in it’s class. The D36-500HD like all of our machines is designed for the severest duty imaginable.
This 36” machine is also designed to do 42” & 48” bores with an optional jacking spacer that raises the centerline while still keeping a low centerline profile. This machine puts out 500,000 Lbs. of thrust and 116,788 Ft-Lbs. of torque making it the most powerful 36” machine on the market.
Our machine uses a 97 HP Caterpillar 4 cylinder engine coupled to a 4-speed transmission and the exclusive Michael Byrne Manufacturing high ratio triple 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 32 Gpm to four (or two for increased speed) hydraulic cylinders with a max pressure of 3,000 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 operator’s view of sight for easy operation. Also included is an emergency switch for total machine shut down. |
