For Caterpillar heavy haul trucks

The Superbolt solution of MJTs, studs and Flexnuts was first installed as an active field test for a mining customer on one of their Caterpillar™ 797s in 2007. The target was to increase the average service life of the bolting by 2.5x — from 800 to 2,000 hours.

The Superbolt solution exceeded the target greatly and this led to the customer changing the entire fleet to Superbolts, thus improving reliability by securing the strut through it’s 18,000+ hour life cycle. With a 22.5x improvement in the life cycle, customers are already seeing a reduction in costs.

A longer life cycle means more savings!

For Komatsu heavy haul trucks

A Superbolt suspension kit was recently installed on a Komatsu™ 960E mine haul truck in central 
Queensland, Australia.

It only took two workers (using safe and easy hand-held tools, with low-input torque) to install the Superbolt suspension kit all in under one hour! The customer’s previous method took four to six hours, utilizing three technicians.

Superbolt has proven strut kits for various haul trucks in the mining industry help improve access to bolting, reduce safety risks, and prevent tooling slippage. The result? Significant savings on repairs and downtime—thanks to our durable, high-performance kits. To date, thousands of kits installed globally with zero failure rate and we’re proud to deliver 100% customer satisfaction every time.
