Vermeer D40x55DR S3 NAVIGATOR® horizontal directional drill
The Vermeer D40x55DR S3 Navigator® horizontal directional drill features dual rod technology that uses an inner rod to provide torque to the drill bit, while the outer rod offers steering capability and rotational torque for reaming. The combination provides powerful downhole cutting action and the flexibility to select the appropriate tooling to best match the ground conditions, which can allow the entire install to be completed with one machine.
The time and steps required to add or remove a rod on the D40x55DR S3 is significantly less than previous Vermeer models due to an enhanced dual drill rod design that quickly and easily makes up the inner and outer rod connections. Install more feet and save time with an impressive 500′ (152.4 m) of drill rod on-board.
Powered by a 140-hp (104-kW) John Deere diesel engine, this drill serves up to 40,000 lb (177.9 kN) of thrust/pullback and 5500 ft-lb (7,457 Nm) of rotational torque, enabling boring through hard rock with less hassle.
A hollow inner rod design results in more air and drilling fluid flow to the drill head on pilot bores and the hole opener during pullback, providing contractors the ability to select from a more diverse range of tooling options, including air hammers and larger hole openers.
