Low clearance, high performance
The CME-55LC gives you all the power and productivity of the standard CME-55 drill. A full length mast is provided for every day wide open spaces. But when overhead space is limited, you can easily change over to low clearance mode. You still have the full 72 inch (183 cm) feed stroke and low clearance sheaves permit full use of hoist lines. A low clearance lifting cylinder allows for normal automatic hammer operation.
Quick disconnect mast
The quick disconnect mast can be secured in its storage rack and removed from the drill by simply sliding the drill back with the hydraulic in/out slide base control. “Quick-cabling” sheaves allow you to easily move the hoist lines from the mast sheaves to the low clearance sheaves provided above the drill frame.
Dependable Cummins power
The CME-55LC offers spindle torque ratings up to 9,425 ft/lbs (12,779 Nm) and spindle speeds up to 800 rpm. That power comes a new Cummins QSF 3.8 turbocharged diesel engine meeting tier-4 final emissions standards.
Unique feed and retract design
The unique design of the CME-55LC feed system eliminates the hydraulic cylinder piston rods that normally extend above the drill frame, yet still provides feed and retract ratings similar to the standard CME-55 drill. Pulldown pressure rating is 27,615 pounds (12,526 kg). Retract pressure is rated at 19,750 pounds (8,958 kg). The fast retract speed of up to 95 ft/min (29 m/min) means more production. The split slide bushings are easily replaced after normal wear intervals, and the standard upright gives you the clearance to drill with up to 10-1/4 inch hollow augers.
Patented Spindle Brake stops rotation in an instant†
Our emergency Spindle Brake can stop rotation in less than a revolution. The system is activated by two conveniently located push button switches as well as strategically located multi-directional wobble switches.
