MOBILE B-57
-
This Mechanical Drill Rig is mounted directly on a tracked carrier enabling easy access to off road locations. Our new B57 track mounted unit meets our customers demands to access sites that conventional truck mounted units have difficulty with.
-
Delivering 20% – 30% more power than drills in its class, the newly designed B57 has undergone engineering upgrades delivering even more geotechnical performance.
-
The new B57 includes a durable 14″ double disc clutch, new single speed RAD, redesigned transmission, rotary box, and more.
-
This rig is equipped with an SPT Automatic Hammer with digital counter.
