Our Sales and Service Team 62

About Megabolt Megabolt is an Australian, family owned business with a reputation for innovation, engineering excellence and after sales service in the mining and civil tunneling industries.

Megabolt is the market leader in the design, testing and manufacturing of high capacity strata support products and systems for underground coal mines, hard rock mines and civil tunneling projects.

Megabolt was incorporated in 1996 when civil engineer Warwick Hutchins and Australias most experienced mine manager Joe Hetherington combined to design a product and system with a simple philosophy to make the industry safer and more productive.

From humble beginnings in West Heidelberg, where each and every cable was made to order, Megabolt now occupies multiple world class factories with over 100 staff.

Our core suite of products now are available ex-stock and can be delivered to most sites in Australia in 1-2 days.

Megabolt is acutely aware that its reputation and industry standing has been built on its ability to listen to the challenges faced by clients and work collaboratively with them to achieve successful outcomes.

Megabolt works closely with mine site geotechnical engineers, civil tunneling designers, production personnel, consultants and contractors to design and implement products and systems to suit the mine, project or clients specific needs based on the prevailing conditions. The dynamic nature of tunnel excavation means that product parameters can vary with changing geotechnical conditions, production requirements / restrictions, timeframes and budgets.

Megabolt has supplied clients with < 100 cables for one off bespoke projects right through to many thousands of cables over the development, production and wind down cycle of a mine site or project.

Whilst Megabolts reputation has been built around engineering excellence and innovation, a significant part of the overall systems success are the ancillary services it provides such as product testing, training and the quality auditing of completed installations. Megabolt does not view itself as just a supplier of products, but rather a partner who is in for the long haul and who takes pride in seeing its products and customers succeed.

Coal Mining Products and SystemsThe name Megabolt is synonymous with the underground coal mining sector. Megabolts strata support products and systems are systematically designed into and used in most longwall mine roof and /or rib support systems in

Australasia.

Whilst Megabolt has a large range of products and systems which have been tried and tested in various geotechnical and strata conditions, we regularly work closely with individual mines, at various stage of the project life cycle to design and implement strata support products and systems that suit the prevailing conditions.

Megabolt products and systems are commonly used right from drift or adit driveage, highwall consolidation, mains development (life of mine), longwall gate roads, longwall bolt ups and specialized projects such as in seam bins, drivehead and transfer point installations and high driveage. Megabolt products are also often used in remedial situations where initial support has been inadequate or there has been a change in the strata conditions.
