Boart Longyear helps drillers recover more core with LF 160 drill rig updates

Boart Longyear is updating its LF™160 surface coring drill rig with, among other things, an inner tube that will allow drillers to retrieve a full 6-m inner tube out of the rod string using the wireline winch.

In addition, Boart is adding foldable walkways and Cummins Tier 3 engines to add efficiency and safety to its LF 160. When paired with the FL262 FREEDOM™ Loader, the LF 160 combination is, the company says, ideal for contractors who want to target sophisticated surface drilling exploration contracts that stipulate some of the highest safety standards, without compromising on productivity. The FL262 Freedom Loader is an innovative rod loading system that requires no intervention from the driller's assistant to trip and align rods or connect to the top drive head.

The company introduced its LF 160 and FREEDOM™ Loader during MINExpo 2016.

The 6-m inner tube, coupled with the capability of handling full PQ inner tubes, means the LF 160 delivers more operating efficiency, reducing the frequency of retrieving the inner tube, which in turn decreases downtime, the company said.

Erik Gaugh, Product Manager – Capital Equipment, said: "Compared to a standard 3-m system, the 6-m inner tube system can deliver efficiencies of up to 50% for deeper holes. We anticipate the 6-m system to be a game changer for many of our customers."

Foldable walkways are available on the LF 160T (truck) and are integrated on both sides of the rig with railings and kick plates, the company explained. The walkways provide safe access to the elevated rig platform on the truck chassis and eliminates the need for fall arrest protection. The walkways hydraulically fold in and out without the need for manual manipulation to further reduce the potential for hand injuries, Boart explained.

The company concluded: "Boart Longyear is committed to providing the safest, most productive, and most reliable rigs in the industry. The foldable platforms, 6-m inner tube system and Cummins Tier 3 engines are continued proof of that commitment."
