Engineered for absolute reliability, precision control, and peak thermal management under extreme airport runway operations.
In modern aviation operations, ensuring flight-readiness requires complex systems. The Aircraft Ground Power Unit (GPU) delivers clean, regulated, and stable power to aircraft while parked on the tarmac. By supplying electrical output—typically 115V/200V AC at 400Hz or 28.5V DC—GPUs eliminate the need to run the aircraft's fuel-consuming Auxiliary Power Unit (APU). This lowers ground operation noise and reduces carbon emissions. Modern GPUs come in various architectures: diesel engine-driven units, solid-state static frequency converters, and emerging lithium-battery energy storage systems (ESS).
As a leading aerospace-grade GSE factory, we design custom GPUs to meet international standards (ISO 461-1/2, DFS 400, MIL-STD-704F, and IATA AHM 905/910). Whether powering regional jets or widebody commercial aircraft, our ground power solutions ensure uninterrupted power during pre-flight checks, passenger boarding, and routine maintenance.
Commercial airlines, military bases, airport operators, and MRO service providers look for specific operational and financial metrics when procuring ground power equipment.
Buyers prioritize equipment that reduces overall operating costs. Implementing highly efficient solid-state rectifiers and smart power management minimizes idle fuel consumption and reduces scheduled maintenance expenses compared to traditional rotary diesel GPUs.
Aircraft operate globally, meaning GPUs must perform reliably in sub-zero Arctic conditions and high-humidity tropical aprons. Advanced IP55/IP65 ratings, heavy-duty anti-corrosive marine paint, and thermal management systems are critical features for global operators.
Fleet operators demand modern connectivity. Our custom GPUs feature CAN-bus integration, real-time telemetry tracking (GPS/GPRS), and remote diagnostics, allowing ground crews to monitor battery health, load cycles, and fuel levels dynamically.
We design and manufacture high-performance aircraft servicing equipment to cover every operational need on the apron.
Our aircraft tank refueling trucks (CD5207GJJ, CD5580GJJ, CD5341GJJ) consist of a chassis, oil tanks, pumping systems, and control systems. They provide filtration, metering, refueling, pumping, self-circulation, and pressure control to ensure safe and efficient fuel transfer.
Heavy-duty, high-capacity mechanical handling units, including Slave Pallet Dollies, 7T Castle Pallet Dollies, New LD3 Container Dollies, and LD6 Container Dollies, designed for smooth movement on the apron.
Includes rainproof luggage carts, enclosed baggage carts, and high-durability steel airport baggage trolleys, built to protect cargo and passenger property in all weather conditions.
