About us
We’re a family-run company with deep roots in mining
Founded by a former miner and carried forward by the next generation, we combine over 45 years of longwall mining shield design experience with firsthand knowledge of underground conditions. We understand the challenges our clients face — because we’ve faced them too.
A small team means effective
There’s no corporate maze to navigate — just focused, personal service from people who understand the industry and care about getting things right. We are a family and you are a part of it when we’re working with you. We care about project success just as much as your mine does.

How we work
From first contact to final delivery, we keep things simple. No long chains of communication or unnecessary meetings — most inquiries are resolved in a single call. You'll speak directly with the people who know your project inside and out.
Custom design
for every project
Every mine is different. That’s why each of our shields is designed from scratch to match your specific conditions and requirements. No off-the-shelf compromises — just exactly what your operation needs.
Prototypes & Production Timeline
Time from drawing board to prototype test completion is around 9 months. After structural testing is complete a full longwall of production shields is fabricated over the course of around 1 year.
