Bulldozer Air Conditioning — Performance Testing in Marikana
This page covers bulldozer air conditioning in Marikana, platinum mining belt within the Rustenburg mining belt. Measured verification of pressures, temperature split and airflow so system condition is a recorded number, not an opinion. Underground machines surfacing for planned maintenance arrive heavily dust-loaded, and surface haulage operates through long hot afternoons. Sealed, positively pressurised cabins are the difference between an operator working a full shift and a machine standing.
Bulldozers in the Rustenburg belt
Dozers building roads and shaping tips around Rustenburg have little travel-generated airflow while working in their own dust cloud. Condenser fans and shrouds therefore matter as much as coil cleanliness during a cabin cooling assessment. Track vibration also warrants checking floor boots and hose chafe points before an apparently successful refrigeration repair is signed off.
Typical specification
18 000 – 24 000 BTU/h typical cabin duty
Low ground speed means little natural airflow through the condenser while radiant heat from the engine bay and the ground is at its highest. Cabin sealing matters more here than on almost any surface machine because the dust source is directly around the operator.
Common problems in this application
- Chronic condenser fouling due to low-speed operation in dust
- High-side pressure rise and cycling on pressure switches
- Cabin seal and floor boot deterioration from track vibration
- Hose chafing against structure and guarding

FAQs
Yes. Marikana falls within our working area around Rustenburg, and attendance is arranged with your site so access, permits and induction are in place beforehand. Marikana is a concentrated platinum mining area east of Rustenburg along the N4/R104 corridor, with shaft complexes, concentrator plants and contractor laydown areas in close proximity.
