A Caterpillar 540-horsepower diesel engine powers Vermeer‘s D330x500 Navigator horizontal directional drill with a 15-horsepower boost over the older D300x500 model. A hydrostatic hydraulic system produces 50,000 feet per pound of rotational torque for drilling in difficult ground formations and delivers 330,000 pounds of thrust/pullback force for long-distance drilling projects. All functions including transport, drilling controls, crane controls and drilling fluid controls are operated from a cab with a 360-degree view. The DP 600 LCD drill monitoring system helps the operator check all drill functions and serves as a diagnostic service tool for troubleshooting.
