Hydraulic drifters at the pinnacle of power.
Our TEI hydraulic drifters feature patented technology that sets our drilling platforms at the pinnacle of power. TEI drifters are designed to provide the power necessary for efficient soil nailing, micropile and other rock and soil drilling applications.
TEI drifters incorporate innovative Automatic Stroke Adjustment (ASA) technology as part of the 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 other manufacturers.
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 feed pressure , TEI’s advanced Automatic Stroke Adjustment reduces the piston’s stroke and frequency, therefore lessening the energy absorbed by the drifter and premature wear on parts.
The ASA action eliminates the wasted energy caused by “dry firing” or using the percussion system with no rock to absorb the energy. TEI drifters are fully bench tested for percussion performance and rotational torque prior to delivery to the end user.
