Sandvik's feed system ensures optimal balance of torque and rotation speed, improving penetration rate and bit life. Like other Sandvik DE100 series models, Sandvik DE142 features a load-sensing hydraulic system for directly proportional oil flow.
Sandvik uses the chainless feed system and increased the power to 90 kW, the extra power is applied directly to the rotation unit through the larger hydraulic motor giving the Sandvik DE142 1250 Nm of torque.
Our H size rotation unit for Sandvik DE142 features a torque of up to 1250 Nm. The speed is infinitely variable from 0 to 1,100 rpm maximum.
Advantages
- Sandvik DE142 is fitted with a rod spin guard to provide maximum safety close to rotating rod string
- Ideal for deep hole core drilling in confined spaces.
- Increased power to 90 Kw
- The load sensing system enables directly proportional oil flow, increasing efficiency
