Tervita hopes rack and pinion technology revolutionizes service rigs

摘要

TERVITA CORPORATION AIMS TO shake up the Canadian service rig with a rack and pinion unit it plans to unleash on operators by the end of 2012.The Calgary-based environmental and energy services company is billing this as a sea change of sorts. Unlike traditional service rigs that use a pulley system to raise and lower pipe, rack and pinion technology uses a system of gears that can pull pipe out of the hole and push it back in utilizing thrust, not gravity.
