The HAC system is a proven method for conveying materials vertically from tunneling operations to the surface.

Designed for high performance

One of the secrets to the high-performance capabilities of the HAC system is its use of pressing mechanisms. The fully-equalized pressing mechanism secures material towards the center 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, mitigating 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.

Standard, smooth surface belts allow continuous cleaning by belt scrapers or plows.  This is especially important in handling wet and sticky material.

Designed for flexibility

The HAC system is adaptable to multi-module sections using self-contained units, as well as single-run systems. In both cases, the conveyor unit may be shortened or lengthened according to the requirements of a new location.

Designed with standard idlers and rolls

The HAC system uses standard conveyor idlers and rolls for greater availability of these replacement components.
