THE INNER TUBE PULLER: A SAFE, PROFITABLE, WELL-DESIGNED INNOVATION

Drill Safe

In March 2018, VersaDrill Canada, a specialist in manufacturing multipurpose diamond drills and innovative products for the mining industry, launched its latest creation: the inner tube puller. MBI Drilling Products is now a proud authorised distributor of this product which, it’s safe to say, is a major step forward for drillers and assistant drillers.

Core extraction
Drillers’ health and safety is becoming a growing concern. Not only are more businesses working on prevention, they’re also aiming to improve their processes to avoid accidents. Core extraction is one such process in need of improvement.

Before, workers needed to force the inner tube out of a borehole. In underground operations or tight spaces, workers may have also needed to work in awkward positions. An inner tube full of rocks weighs approximately 75 lbs over 3 m, meaning that a 6 m tube can weigh 150 lbs!

Naturally, this puts constant strain on workers’ backs, making it one of the leading causes of absenteeism. What’s more, most workplace accidents are caused by excessive effort. That’s why it’s important to find a solution to make workers’ duties easier.

How it works
The patented rollers, the primary component of the inner tube puller, have been thoroughly studied to maximise grip and avoid slippage and drill rod deformation. It’s crucial that the inner tubes don’t slide back into the hole. That’s why a diamond coating was developed. Each diamond tip gently grips the inner tube to create optimal traction with minimal axial force.

The radius of the rollers was specifically designed to avoid deforming the tube. Additionally, a special diamond layer eliminates excessive friction between the tube and the rollers.
