| LEFFER RDM 3.0M ROTATOR
The Leffer 3.0M rotator is a boring machine
capable of drilling a 3.0M hole over 200 ft in depth
providing casing to the bottom of the bore hole. This
fully cased method causes less overbreak and creates
a cleaner pile.
The machine has over 5 million ft-lbs of torque and
1 million lbs extraction force. By using reduction inserts
the diameter can be reduced to 2.8M or 2.5M.
Clean out of the cased shaft is accomplished by using
a large grab in conjunction with a heavy duty crane.
