Alimak Hek are most often associated with construction and port applications – but many mines, both above- and underground, use Alimak Hek lifts in pelletising plants, smelters, concentrators, and other ore processing plants.
The wire hoist lifts are highly suitable for carrying heavy loads at relatively fast speeds and is the primary means of vertical access for men and materials in an underground mine. Alimak rack and pinion elevators are ideally suited for providing secondary and emergency vertical access required by mine safety regulations.
Alimak elevators are also used to provide a simple and economical means of connecting different levels further out in the tunnel system and for transporting men and material between the levels and the stopes. The elevator can be installed easily, and the cost is moderate because no machine room is needed.
At crushing plants, where the operator has to control feeders, bins, conveyors, etc., which are installed at different levels, the Alimak elevator may offer the best solution for rapid movement between levels.
Alimak Hek also supports the construction of mining facilities with temporary vertical access solutions.
Boliden’s Aitik copper mine, in northern Sweden, has no less than seven Alimak Hek elevators working at both the pit, crushing and concentration plants.
