Explore our top-performing GSE dollies, baggage carts, and specialized airfield handling systems designed for maximum durability and efficiency.
In modern commercial and military aviation, ground operations dictate the efficiency of the entire flight schedule. A Ground Power Unit (GPU) acts as the electrical lifeline for aircraft while parked on the tarmac, loading bays, or within Maintenance, Repair, and Overhaul (MRO) hangars. By supplying continuous, stable 400Hz AC or 28.5V DC electrical currents, GPUs allow aircraft systems to remain operational without burning expensive jet fuel through the Auxiliary Power Unit (APU).
Reducing APU cycles is not merely a cost-reduction strategy; it is a regulatory imperative. Global airports are implementing strict carbon emission rules and noise mitigation mandates. The adoption of optimized Ground Power Units reduces localized CO2 emissions and tarmac noise levels, creating safer, cleaner environments for ground crews.
The aviation industry is transitioning toward electrification and smart operations. Our R&D division is actively leading this transformation with four clear technical pathways:
Replacing mechanical rotary systems with semiconductor-driven solid-state technology. Our converters utilize high-power IGBT (Insulated Gate Bipolar Transistor) modules to deliver clean, quiet, and vibration-free energy transfer at 95%+ conversion efficiency, significantly lowering maintenance costs.
Providing towable, battery-operated GPUs that eliminate localized emissions entirely. Operating quietly on the tarmac, our energy storage GPUs (ESS-GPU) support multi-aircraft turnarounds on a single charge and recharge via standard hangar utilities or solar grid connections.
Real-time telemetry tracking voltage spikes, internal battery cell temperature, output currents, and geographic coordinates. Our smart software integrates with airport management suites via secure API, enabling predictive maintenance models that prevent sudden operational failure.

Ground support operations vary greatly depending on the field of application. We develop custom Ground Power Units tailored to the specific challenges of each environment:
Manufacturing reliable GSE requires advanced logistics, strict quality assurance, and automated precision. Our state-of-the-art Chinese manufacturing facility leverages Industry 4.0 paradigms to deliver key benefits to our global partners:
By producing critical copper transformers, cabinet enclosures, and electrical distribution boards in-house, we eliminate reliance on third-party suppliers. This allows us to offer shorter manufacturing lead times and strict control over structural integrity.
Every single Ground Power Unit runs through a 100% full-load burn-in chamber for 48 consecutive hours. We simulate dynamic load steps, short circuits, high ambient humidity, and extreme heat profiles before the unit receives clearance for delivery.
From custom paint configurations to specific chassis designs matching regional tow couplers, our CAD engineers can quickly alter designs. We adapt to your requirements, delivering custom configurations in as little as 6 to 8 weeks.
Our location in China's industrial manufacturing heartland secures long-term steel, copper, and semiconductor contracts. This insulates our global clients from volatile raw material pricing fluctuations and supply bottlenecks.
