TEI HYDRAULIC DRIFTERS
Our patented ASA technology sets TEI hydraulic drifters at the pinnacle of power.
Quality is built into every American-made TEI drifter. TEI’s full line of hydraulic drifters feature patented technology that sets our drilling paltforms at the pinnacle of power. TEI drifters are designed to bring the power necessary for efficient soil nailing, micropile and other rock and soiling drilling applications.
Unlike other manufacturer’s equipment, TEI’s patented technology only produces full impact energy when the drill string is engaged. When hitting a void or not having enough down pressure on the mast, TEI’s advanced Automatic Stroke Adjustment reduces the piston’s stroke and frequency, lessening the energy absorbed by the drifter. This action eliminates the wasted energy caused by “dry firing” or using the percussion system with no rock or soil to absorb the energy.
TEI drifters incorporate innovative Automatic Stroke Adjustment (ASA) technology as their percussion system. The high frequency and smooth operation of the ASA system increases productivity and extends the equipment’s life cycle well beyond the dated drilling technology employed by many manufacturers. Automatic Stroke Adjustment reduces the frequency and stroke of the piston, which only comes to full power when the shank adapter pushes the piston back into the full-firing mode.
TEI drifters are fully tested for accurate percussion and rotational torque to insure delivery of world class TEI equipment.
