-System that provides heat on the cabin during drilling and tramming phases.

-Reduce risk of accident due to negative effect of cols ambient temperature.
-Improve operator’s comfort.


Cold temperatures have hazardous effects on humans and their ability to work well. When the body is exposed to cold temperatures, the negative effects can includes dehydration, numbness, shivering, frostbite and hypothermia. This can lead to extended reactivity time, fatigue, uncontrolled movements or loss of lucidity that increase the risk of loss of control and accident.

In order to mitigate this risk, Sandvik has developed Heating Systems for their Underground Drills equipped with cabin. The Heating Systems are able to generate sufficient heat in the cabin, even on the coldest ambient temperatures.

On D301 series, the heating system consist on a “mini boiler” fuelled by diesel (from unit diesel tank). The system is operational on both drilling and tramming modes.

On larger units, the heating system use cooling fluid from the engine cooling system to generate heat while the engine is running (tramming phases). During drilling phases, the heat is generated by electric resistance located on the AC system.

The temperature on the cabin is fully adjustable with a simple knob.
