Huck C50L Lockbolt fulfills 10 years of crushing demands

The introduction of a new fastening system on quarrying machinery in 1995 has led to a decade of successful business between two manufacturing companies in the UK and France.

Metso Minerals, part of the Metso Corporation, is the global market leader in the supply of equipment, service and process solutions to industries including quarrying and aggregates production, mining and minerals processing, construction and civil engineering, recycling and waste management. Although their headquarters are in Tampere, Finland the offices and plant in Macon, southern France employ 400 people and manufacture approximately 700 crushing and grading machines per year for markets in Europe and Africa. The operation also carries out crucial design-and-test engineering decisions affecting Metso’s factories worldwide.

Alcoa Fastening Systems Ltd (AFS), with Huck® fasteners as their primary brand, engineer high-quality, high-performance fastening systems serving a variety of applications predominantly in the truck, trailer, commercial vehicle body builder, auto and railcar markets. Although based in Telford (England) they have a dedicated commercial sales team and well established distribution network throughout France and the rest of Europe.

Jean-Claude Berthet, purchaser at Metso Minerals explains why the decision to use C50L has been so successful: "We originally fastened parts of the machinery together using a nut and bolt mechanism but when in 1995 customer requirements dictated that the speed of our machinery needed to increase, we had to look at alternative options. Using the C50L has not only allowed for faster rubble processing and grading on larger machines with high fatigue loads, but the increased vibration resistance provided by the system has led to a reduction in maintenance time. In addition, C50L Lockbolts fit precisely into our new laser drilled holes."

Allan Binstead, commercial director for AFS, said: "The Metso Minerals story is a good example of why the Lockbolt was first invented by Lou Huck – to eliminate the dangers caused by fastening systems unable to tolerate extreme vibration conditions. The C50L has passed the test over the past ten years and I’m sure it will continue to do so long into the future."
