Explore our industrial-grade, certified aircraft start units, deicing trucks, passenger boarding stairs, potable water service vehicles, and heavy-duty towing assets engineered for zero downtime operations.
In modern commercial and military aviation, the aircraft parked at the gate or in the maintenance hangar requires constant electrical power to run flight control computers, avionics, lighting, and environmental control systems. To prevent the wear, noise, and carbon emissions associated with running the aircraft’s Auxiliary Power Unit (APU) or main jet engines, advanced airports rely heavily on dedicated ground support equipment—specifically, Aircraft Ground Power Carts (GPUs).
Did you know? Transitioning tarmac operations from APU usage to stationary ground static power supplies reduces local carbon emissions by up to 90% and decreases localized airfield noise pollution by 20 to 30 decibels, facilitating a healthier work environment for ground crew and meeting aggressive municipal net-zero goals.
Aircraft operate on specific electrical systems. Standard utility power runs at 50Hz or 60Hz. However, modern commercial aircraft (such as the Boeing 787, Airbus A350, and regional jets) utilize lightweight components designed for 400Hz Alternating Current (AC) systems. This high frequency allows engineers to utilize significantly smaller and lighter transformers and motors within the airframe, reducing overall payload weight and fuel burn during flight.
Conversely, many military transport aircraft, smaller turboprops, helicopters, and private business jets utilize 28.5 Volts Direct Current (DC) systems. Our factory produces high-spec dual-output units capable of supplying both high-grade 400Hz AC power (typically 90kVA, 120kVA, or 180kVA configurations) and stable 28.5V DC output, ensuring full operational capability regardless of the aircraft parked on the apron.
Utilizing high-efficiency Silicon Carbide (SiC) MOSFET inverter bridges. Solid-state units provide noiseless operation, zero emissions, and require minimal maintenance due to the absence of mechanical wear parts.
Powered by Tier 4 Final/Stage V diesel engines (such as Cummins or Deutz) integrated with heavy-duty alternator assemblies. Best suited for remote runways, military deployment sites, or off-grid maintenance complexes.
Using high-capacity Lithium Iron Phosphate (LiFePO4) battery packs. These mobile energy storage units combine the zero-emission characteristics of solid-state systems with the off-grid autonomy of diesel generators.

The civil aviation sector accounts for a notable portion of global transportation emissions. While alternative sustainable aviation fuels (SAF) and hydrogen-powered engines target in-flight emissions, airports are working to eliminate ground-level emissions. The electrification of mobile ground support equipment (eGSE) has progressed from an environmental goal to a standard regulatory requirement in many regions.
Advanced airport hubs in Europe, North America, and East Asia are implementing policies to restrict or phase out internal combustion engine (ICE) ground vehicles. Consequently, purchasing managers are prioritizing electric ground power carts, battery-operated baggage tow tractors, and electric passenger boarding stairs to future-proof their operations.
BESS (Battery Energy Storage System) Integration: The newest generation of our ground power carts incorporates LFP (Lithium Iron Phosphate) battery storage arrays.
