The HAC system is a proven method for conveying materials 90° vertically from tunnelling operations to the surface.
Designed for high performance
One of the secrets to the high-performance capabilities of the HAC system is in its use of pressing components. The fully equalized pressing mechanisms secure materials towards the centre of the belt while gently, but effectively, sealing the belt edges together.
During operation, the conveyed material remains sealed between the carrying and cover belts, decreasing the potential for spillage along the conveyor length.
The pressing mechanism does not confront the material; instead, it conforms to the surface shapes using soft, gentle pressure. This helps ensure both the preservation of the conveyed material and the conveying system.
Another performance feature is the use of standard, smooth surface belts. These allow continuous cleaning by belt scrapers or plows, ensuring high throughput of wet and sticky materials.
Designed for flexibility
The HAC system is adaptable to multi-module sections using self-contained units, as well as single-run systems. In the both cases, the conveyor unit may be shortened or lengthened or the conveying angle may be altered according to the requirements of a new location.
Designed for ease of maintenance
The HAC system uses standard conveyor idlers and rolls, ensuring that component replacement is quick and easy.
