Dependable Cummins diesel power

CME-45B Trailer Mounted Drill The CME-45B is powered by a Cummins QSF 2.8L 171 cubic inch 65 Horsepower Tier-4 final diesel engine.

Hydraulic feed and retract system provides 19,600 pounds (8,891 kg) of retract force and 13,650 pounds (6,192 kg) of down pressure

Twin 68 inch (173 cm) stroke hydraulic feed cylinders are aligned with the rotary drive coupling so that vertical drive forces are applied directly to the tool string.

Rugged mechanical rotary drive with up to 4,858 foot pounds (6,587 Nm) of torque

Several torque and rotation speed combinations are available, including a high-speed rotary drive that gives you up to 760 rpm. The four speed transmission is connected to the drill engine through a heavy-duty clutch. With four forward gears and one reverse, there’s a rotation speed and torque combination available for just about any situation. The mechanical rotary drive also gives you a good feel for changes in soil and drilling conditions down the hole. It allows you to sense the need to adjust feed pressure and rotational torque.

Control logic — the key to operator productivity

All drilling and set-up controls are logically arranged on a control panel located at the drillers station. A lock-out position for the clutch lever helps prevent accidental engagement. And since the transmission does not travel vertically with the spindle, you won’t find yourself unable to change gears when you’re at the top of the feed stroke.

Patented spindle brake stops rotation in an instant

CME-45B Trailer Mounted Drill Control PanelOur emergency spindle brake can stop rotation in less than a revolution. This system is activated by two conveniently located push button switches, as well as by strategically located multi-directional wobble switches. All switches are located on the drill and are not affected if removed from the carrier.

CME designed drill trailer

The CME-55BT trailer is designed specifically for the CME-45B drill. It accommodates all of the typical drill functions while considering weight distribution for transport. Tool boxes, auger and drill rod racks are standard equipment. Tandem 8,000 pound (3,629 kg) axles with electric brakes provide enough capacity for the drill and everything you can carry to support it.

Leveling system

The CME-55BT trailer is equipped with three hydraulic leveling jacks. Two jacks are mounted at the rear and a third is at the front. The 36-stroke offers easy leveling regardless of the site conditions.
