New Vermeer feature simplifies drill rig connections on intersect bores

AutoTension can be used with D220x500 S3 and D550 HDDs to streamline large and long-distance bores

Vermeer is enhancing the capabilities of the D220x500 S3 and D550 horizontal directional drills (HDDs) with an optional AutoTension feature that maintains a steady tension force on the drill string, helping to streamline large diameter and long-distance intersect bores.

After completing a pilot bore, a drill outfitted with AutoTension allows HDDs on both sides of the bore to work together to increase the efficiency of reamer passes and the process of adding or removing drill rods to the tail string. 

Enhanced flexibility and efficiency for intersect bores

"The HDD industry is witnessing a growing trend of employing a drill rig on each side of a large diameter or long bore," says Marv Klein, application specialist for Vermeer. "With Vermeer AutoTension on the D220x500 S3 and D550, crews on the entry and exit side of the bore can work together while reaming and swabbing a bore hole. This leads to more efficient and accurate reamer passes without the need for a mechanical locking swivel or breakout tongs for rod handling. Also, AutoTension helps optimize fluid management on the job because the need to transport fluids using vacs or pumps from one side to the other is reduced because crews can pull ream and pump fluids from either side."

The AutoTension feature, engaged from the control station, is designed to maintain a desired tension on the tail string throughout the drilling process. It allows for rod additions or removals without halting operations. This flexibility extends to directional changes, enabling the driving machine to switch between pushing and pulling without requiring action from the operator in the other drill.

Embedded safety system

The AutoTension feature also includes a lack of operator presence safety system. When the AutoTension operator leaves the seat, certain controls are locked out and an audible alert sounds at the AutoTension machine.

This new feature offers several key benefits to HDD crews. It optimizes reamer penetration through consistent tension application and improves positioning and control of the reamer within the bore hole. Moreover, AutoTension helps maintain the intended bore path and reduces potential complications during the drilling process, says Vermeer.

Contractors can match different Vermeer HDDs with the D220x500 S3 or D550 using AutoTension. Also, people who already own a D220x500 S3 or D550 can add this feature to their units. An authorized Vermeer dealer will need to help execute these upgrades.
