I
n 1991 Trevor Robinson, the proprietor of Boltstress Ultrasonics, entered the world of Ultrasonic Bolt Tension Monitoring. Emigrating in 1996 he quickly realised that the Australian /mining Industry had several bolting challenges that could be solved. In 2004 he established Boltstress Ultrasonics, working primarily with Grinding Mill Critical Fasteners.
Following 3 years of close cooperation Boltstress Ultrasonics Pty. Ltd & Norbar Torque Tools Pty. combined their strengths to become the Norbar Technical Services Division in January 2014.
This unique partnership combines the best practice of both companies. Boltstress Ultrasonics has over 30 years of field experience in ultrasonic tension measurement. Norbar, with over 80 years of experience, is the market leader in the field of Torque.
The key success came from consulting with clients to prevent bolted joint failures and implementing corrective actions that also reduce assembly and shutdown durations.
Boltstress have been particularly active in the mining industry, having completed the structural bolting of 68 of the world’s largest mills. In addition to this, we maintain the integrity of over 100 mills using our annual health check.
In recent years many clients have benefitted from our work on mill liner bolting. In a nutshell we eliminate both all liner bolt failures and the need to retorque 24 hours after the original reline.
