CME-55 Trailer Mounted Drill Rig Features

A towable classic

The first CME-55 drill was produced in 1963. It was an immediate success and continues its popularity today. The trailer mounted version of this classic offers the same power and durability in a portable configuration. The CME-55T trailer is designed specifically for the CME-55 drill which means best possible weight distribution and use of available space.

Hydraulic feed system

The hydraulic feed and retract system provides 28,275 pounds (12,826 kg) of retract force and 18,650 pounds (8,460 kg) of down pressure. The 72 inch (183 cm) feed stroke is provided by twin hydraulic cylinders mounted in line with the drill spindle for precise control of force on the drilling tools. The split feed 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 inside diameter hollow stem augers.

Mechanical rotary drive

Rugged mechanical standard rotary drive provides 7,780 foot pounds (10,548 Nm) of torque and rotary speeds of up to 800 rpm. Other rotation and torque combinations are available, including a high-torque rotary drive that gives you up to 9,425 foot pounds (12,778 Nm) of torque and rotary speeds of up to 665 rpm. The five speed transmission is connected to the drill engine through a heavy-duty 13 inch clutch. With five forward gears and one reverse, there is a rotation speed and torque combination for just about any situation. The mechanical drive system also gives you a better feel for drilling conditions down the hole. It allows you to sense the need for changes in feed pressure and rotational torque.

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.

Control logic — the key to driller productivity

All drilling and set-up controls are logically arranged on the control panel located at the drillers’ station. The most commonly used functions, such as the feed, hydraulic hoist, and sliding base levers are staggered for easier identification and operation. Also a lock out position for the clutch lever to prevent accidental engagement.

Tool storage

Four tool boxes provide plenty of storage. Tool boxes are mounted forward to help distribute the weight evenly on the trailer. Drill rod and auger rack are mounted over the fenders on both sides of the CME-55T trailer.

Leveling system

The CME-55T 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 jack cylinders make it easy to level the rig regardless of the site conditions.
