Shuttle Cars Air Conditioning and HVAC Repairs

HVAC systems on shuttle cars

Compact operator station cooling and ventilation where an enclosed station is fitted. Repetitive short travel cycles in confined headings with dust generated at both loading and discharge points.

Common faults we find on shuttle cars

• Duct blockage
• Fan failure
• Weak cooling
• Connector corrosion

Diagnostic process

• Operator interview and fault confirmation with the machine running under load
• Visual inspection of condenser, belts, hoses, wiring and cabin filters
• High and low side pressure testing against the manufacturer's specification
• Electronic leak detection, dye tracing or nitrogen pressure testing where required
• Electrical fault finding on clutches, relays, pressure switches and control modules
• Written findings, parts list and repair recommendation before work proceeds

Repair approach

• Correct recovery of refrigerant before any component is opened
• Compressor, condenser, evaporator, drier, valve, blower and harness repairs or replacement
• System flushing and drier replacement after contamination or compressor failure
• Vacuum, leak hold test, charge by weight and oil balance to specification
• Function test across the full temperature range with cabin outlet readings recorded

Preventative maintenance recommendations

Duct and fan inspection, filter renewal and wiring checks at each service.
