The Errickson TR-26 casing advancement system allows advancing the casing and hammer through rock simultaneously.
Along with most business owners, foundation and caisson drilling companies are doing their best to reduce costs during these stressful economic times. One way to make an improvement to the bottom line, would be to use Errickson’s TR-26 casing advancement system, which allows users to advance casing and hammer through rock, simultaneously.
Manufactured in the United States, the Errickson casing advancement system is engineered to include large tapered roller bearings, Martin sprockets, Brovini drive motors and Garlock sealing. Each unit is hand built under the direction of its designer, Jon Errickson. He also maintains an extensive manufacturing facility with all the equipment and skill to keep each unit in house, from start to finish.
“Since 1977, we have drilled in almost all geological conditions,” said Errickson, who owns and operates Precision Drilling Inc., a New Jersey-based foundation drilling company. “I’ve spent an enormous amount of time and effort leading up to our TR-26 prototype, and feel we’ve finally put together a unit that can withstand the rigors of any drilling condition. I’ve even included a fully adjustable 140-4 roller chain to increase the unit’s durability. It was important to create a unit without boundaries.”
Once the prototype was completely tested and approved by Errickson, he designed a smaller, less expensive unit, to be primarily used by the well drilling industry. He replicated his component choices to the larger design.
“We have two bullet-proof case sizes,” said Errickson. “The larger, or the TR-26 case, will allow you to drive from 6 inch up to 26 inch casing, and the smaller TR-16 unit, for 6 inch to 16 inch casing. You simply need to change the jaw sets for the new casing being used. It only takes about five minutes with regular hand tools.”
Included in the purchase price is one jaw set size of your choice. Other size jaw sets are manufactured on site and are readily available.
“The addition of our CADD-controlled plasma machine has enabled us to cut with greater precision, provide a better product and eliminate outsourcing,” said Errickson. “Many parts, even our 3 inch thick T-1 jaws, are professionally cut using this machine.”
The torque of each unit is derived from the combination of planetary gears, the hydraulic drive motor, and the customer-supplied hydraulic GPM and PSI. Each of these plays a role in arriving at the required torque specification.
“We start by asking our customer two important questions: Their machine’s hydraulic specifications, which will power our unit, and how much torque they need. Then, it’s off to the drawing board to determine how to get there.”
According to Errickson, the possibilities are endless.
“The only part of our TR units that can be considered ’standard’, are the cases. All the components within are ’customer and rig-specific’.”
Errickson’s TR units can be mounted on excavators and lead systems, as well as drill rigs. The installation also requires a mounting plate, allowing the unit to bolt on to the customer’s equipment. Errickson supplies a pre-drilled plate, once given an accurate bolt configuration. In addition, they manufacture rotational and non-rotational diverters, helping to localize spoils.
“We’ve recently completed a box lead system, utilizing a TR-26,” said Errickson. “It’s controlled remotely and run by a power pack. All they need is a crane to hold the leads at whatever angle they need. We supply everything else. We’re anticipating a strong rental market for those.”
