System delivers instrumentation for drillers
TruCore is an integrated core orientation system that enables drillers to increase productivity and decrease spend on consumables, Boart Longyear says. According to the company, when compared with other systems, additional extensions are not needed when the integrated TruCore housing is combined with Boart Longyear’s outer tubes. Boart Longyear says TruCore’s marking technology allows one tool to always be in the hole. The design uses optical communication to send measurements to a handheld control device, allowing the drill string to stay assembled. The pocket-sized controller simultaneously controls the two core orientation instruments, increasing productivity by validating measurements while minimizing errors. boartlongyear.com Keep Reading

Set work mode to optimize efficiency
The EC480E crawler excavator lowers operating costs through reduced fuel consumption and simple maintenance requirements, according to Volvo Construction Equipment. A Tier 4 Final Volvo D13 engine powers the excavator, delivering high digging and breakout forces along with reduced emissions and improved fuel efficiency, the company says. An integrated work mode system offers operators a choice of work modes according to the task at hand, including idle, fine, general and heavy. When the controls are inactive for a preset amount of time, the excavator can be programmed to automatically reduce engine speed or even shut down to further reduce fuel consumption and noise. Operators can keep track of both current and average fuel consumption via a gauge in the cab. volvoce.com Keep Reading
Put to the test
A massive portable cone crusher helps a West Coast producer maintain production while moving from site to site. Few producers ever get a chance to work closely with a manufacturer to help research and develop a product. J.L. Storedahl & Sons Inc. was recently given this chance, specifically to test the largest cone crusher one manufacturer makes. The opportunity was too good for the producer to pass up. J.L. Storedahl, which is located about three hours from KPI-JCI and Astec Mobile Screens’ Oregon manufacturing facility, first considered a partnership with the manufacturer when it began searching for a portable, heavy-duty, 500-hp cone crusher in 2013. After meeting with Astec AggReCon West, a KPI-JCI and Astec Mobile Screens dealer based in Eugene, Ore., J.L. Storedahl determined it would test one of the company’s new Kodiak Plus K500+ cone crushers in exchange for providing feedback on the machine’s performance. Although the arrangement was initially intended to last four to five months, the company is still using the cone crushing plant today – nearly… Keep Reading
