Safe brake makes mining safer

0

Products that create a safer working environment are in high demand from the mining industry, and now a new ‘safe brake’ product designed by Custom Fluidpower has won a Safety Innovation Award at the 2015 Queensland Mining Industry – Health & Safety Conference, held in August outside of Brisbane, Australia.

Custom Fluidpower embraced the challenge to fix a cable problem on a coal mine shuttle car. With safety in mind, it engineered the shuttle car cable reeler with a brake apply interlock valve for a Mackay-based coal mine.

“We are delighted that one of our engineered system designs has achieved such a rewarding result, for both our client and at the 2015 product innovation awards,” said Matt Doolan, Custom Fluidpower – Mackay Branch Manager.

The custom-designed device comprised a full upgrade to the hydraulic control circuit. Custom Fluidpower designed, manufactured and installed a new hydraulic manifold to the park brake control circuits on all mine site shuttle cars.

The impressive ‘safe brake’ safety features that were incorporated into the product design include:

• The park brake becomes activated when the cable reeler motor pressure drops below 800psi – the brake can only be released by a manual override or if pressure rises above 800psi.

• A bypass valve has been installed into the circuit, allowing the park brake to be released when being towed.

• In the event that the bypass valve has been left in the towing position during normal tramming operation, the brakes will not release.
