Horizontal directional drill offers additional versatility

Horizontal directional drill units are sizable investments for any utility construction company. That’s why identifying a unit that offers multiple configurations can offer your business the most efficiency.

The D220x500 S3 Navigator horizontal directional drill from Vermeer fits the bill. With the ability to be configured for large-diameter water and utility installs in urban areas as well as challenging pipeline work, the unit delivers up to 54,000 foot-pounds of torque at a spindle speed of 36 rpm, and fluid flow rates of up to 350 gpm if the onboard pump is selected. Contractors can choose between a rod stager or full-length catwalk as well as add an optional mud pump, crane or hydraulic scissor lift for optimum staging efficiency. 

“The D220x500 S3 integrates many of the quality features found on the Vermeer D220x300 S3 Navigator HDD, but with even more versatility and ramped-up performance,” says Tod Michael, product manager of trenchless products for Vermeer. “This drill is designed to meet the needs of utility contractors performing large-diameter city work as well as pipeliners that are performing long, large-diameter bores.”

Its 30-foot rack gives crews the ability to use a variety of range 2 drill pipe at various diameters and a range of 29 feet to 32 feet in length — an ideal setup for performing pipeline work. This rack configuration can be paired with a rod stager that holds four rods or a full-length catwalk. Crews will also like the benefits of using the optional hydraulic scissor lift with the rod stager to help reduce drill rod and wireline staging cycle times. Also, if paired with a stand-alone pump, the unit, with its four 1.5-inch mudlines and 3-inch head shaft, can accommodate 650 gpm of downhole drilling fluid flow. 

For more mobile operations, the D220x500 S3 can be equipped with an onboard excavator-style cab that has a view of the open-top vises as well as the rack and rod stager. It is built with a 415 hp Cat C13 ACERT Tier 4 Final engine that is convenient to service. The drill also runs quiet at just 81.2 dBA. 

“The combination of the D220x500 S3 drill’s rotary torque and fluid pressure delivers optimized drilling and reaming performance in challenging ground conditions like rock,” Michael says. “More torque helps reduce the number of reamer passes crews need to make when widening a hole, and high fluid flow helps protect tooling while maintaining the drill hole integrity and operational efficiencies.”
