The high angle conveyor (HAC) system is a proven method for conveying materials 90° 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 in its use of pressing components. The fully equalized pressing mechanisms secure materials 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, 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 uses self-contained units, which can be efficiently used to create multi-module conveying systems. In addition, the HAC system can be used in single-run systems using externally anchored HACs.

In the both cases, the conveyor unit may be shortened or lengthened or the conveying angle may be altered based on the location’s requirements.

Designed for ease of maintenance

The HAC system uses standard conveyor idlers and rolls, ensuring that component replacement is quick and easy.
