Heavy Equipment Air Conditioning by Machine Class
Every machine class fails differently. These profiles document the components, failure modes and service strategies specific to each.
Interactive HVAC service points
Hover or tap the marked points on each machine to reveal the serviced components.
Haul Trucks
Large-capacity haulage units running continuous cycles in high-ambient pit conditions with severe dust and vibration exposure.
- Condenser fouling from pit dust reducing heat rejection
- Hose fatigue from sustained chassis vibration
- Cab pressurisation loss allowing dust ingress
Excavators
Hydraulic excavators with tight engine bays, high radiant heat and continuous slewing loads on refrigerant lines.
- Radiant heat load from hydraulic systems
- Slew-induced line stress and leaks
- Restricted access for condenser cleaning
Bulldozers
Dozers operating in extreme dust and heat with heavy shock loading through the cab structure.
- Shock loading on compressor mounts
- Rapid filter blockage in fine material
- Cab seal degradation
Loaders
Front-end loaders in short high-frequency duty cycles with constant articulation across HVAC service lines.
- Articulation wear on flexible lines
- High idle-heat soak in cabs
- Frequent door cycling increasing cooling load
Drill Rigs
Surface and underground drill rigs where cab air quality is a direct health control against airborne silica.
- Silica-laden air requiring high-grade filtration
- Long stationary duty in direct sun
- Vibration from percussive drilling
Mining Vehicles
LDVs, personnel carriers and supervisor vehicles requiring high-volume, fast-turnaround AC servicing.
- Large fleet volumes with limited release windows
- Mixed makes and inconsistent parts holding
- Corrosion in wash-down environments
Earthmoving Equipment
Graders, scrapers and ADTs across civil and mining earthworks with long travel distances between service points.
- Remote breakdown locations
- Mixed-age fleets with legacy systems
- Component obsolescence
Mobile Plant
Mobile crushers, screens and support plant with operator cabins and electrical enclosures needing active cooling.
- Combined cab and panel cooling demand
- Heavy particulate loading on coils
- Frequent relocation disrupting service schedules
