The short carriage of the McL-12HB enables setup in trenches only 7’ in length using 4’ auger flight for free bore applications and case bore using 10’ sections of pipe (Steel or PVC) with a 13’ track.
With remote hydraulic quick disconnects, the McL-12HB can be powered with a backhoe, mini excavator or power pack.
Foot-actuated, spring-loaded dog plate provides a simple and reliable method for quickly securing and retracting dog pins.
READY TO WORK
Powerful hydraulic motor generates 1030 ft-lb torque @ 2500 psi tough boring conditions.
DESIGNED FOR PRECISION
The in-line dual hydraulic cylinder design allows for maximum thrust of 24,500 lbs at 2500 psi on the bore centerline ensuring thrust is delivered in-line with the auger carriage and features a casing pusher for up to 10” diameter sections of pipe.
Variable speed hydraulic valve provides up to 120 rpm auger speed @ 20 gpm for controlled boring installations.
The ON TARGET system allows contractors to also control the direction of the bore in a lateral movement, providing more accuracy for difficult on-grade bores ranging from 16 to 60 inches in diameter.
