Premium Dollies, Transport Equipment, and Container Handling Solutions Manufactured to International Aviation Standards.
In modern commercial aviation infrastructure, the efficiency of ground operations relies on sophisticated, reliable, and standardized systems. Among these systems, the Aircraft Ground Power Unit (GPU) acts as a primary energy delivery asset. When an aircraft is parked on the apron with its main turbine engines shut down, a GPU provides stable electrical power. This electrical supply supports safety critical operations, passenger pre-boarding comfort, pre-flight system diagnostics, avionics calibration, and structural auxiliary power.
Historically, auxiliary power units (APUs) installed in aircraft tails supplied parked aircraft with electrical energy and pneumatic power. However, running an onboard APU consumes high amounts of expensive aviation turbine fuel, generates high levels of local particulate matter (PM2.5) and carbon emissions, and produces loud noise across the apron. Modern smart airports now mandate the use of land-based, ground-supported power solutions. Transitioning to dedicated ground-based 400Hz and 28.5V DC power systems allows operators to lower fuel consumption, improve safety, and control emissions.
Aviation ground power must meet strict technical specifications. Unlike domestic grid distribution systems running at 50Hz or 60Hz, standard aircraft operate on high-frequency 400Hz AC power systems. This design reduces the weight of aircraft generators and magnetic components like transformers and motors. GPU manufacturers design power supplies that convert municipal 50Hz/60Hz grid power, or mechanical diesel engine rotations, into stable 400Hz AC power or 28.5V DC power.
Quality GPU units must maintain clean electrical output to prevent damage to sensitive avionics. The output sine wave must show less than 2% Total Harmonic Distortion (THD) under balanced linear loads, and individual harmonics should not exceed 1.5%. Voltage regulation must remain within ±1% from zero load up to a 100% load change, with recovery times under 10 milliseconds. Dynamic load testing ensures that sudden connections of large inductive loads, such as cabin air conditioning compressors, do not destabilize the system.
Modern apron logistics require more than just power supply units. The speed and safety of turnaround operations depend on various mechanical assets designed to transport, service, and supply the aircraft.

The aviation sector is undergoing a major shift. Airports worldwide are committing to net-zero carbon goals. The International Air Transport Association (IATA) and the Airport Council International (ACI) have set target timelines to reduce emissions from ground handling equipment.
Because diesel emissions on the apron impact worker health and contribute to city-level smog, major airport hubs are converting their ground fleets to electric power. Ground Power Units (GPUs) are at the forefront of this change. Replacing diesel-powered generators with solid-state or battery-powered ground power units helps reduce local carbon footprints and lowers operating costs. Solid-state frequency converters operate at up to 95% efficiency, while diesel-driven units typically reach only 30% to 35% thermal efficiency. This efficiency difference helps reduce fuel and maintenance costs.
Many airports now restrict auxiliary power unit (APU) run times to less than 10 minutes post-arrival. This restriction requires immediate connection to ground power and air conditioning services. Meeting these regulations requires high-capacity static power systems and reliable ground support equipment like high-tensile dollies and baggage systems.
As a ground support equipment manufacturer, we offer comprehensive OEM and ODM services. Customizing GSE requires detailed knowledge of structural engineering, metallurgy, electrical conversion, and automation. Our design process ensures that each piece of equipment is tailored to the client's operational environment.
We build our dollies, luggage carts, and vehicle frames with high-tensile structural steel (like Q355B). Welded assemblies are hot-dip galvanized to protect them from corrosion caused by weather and runway de-icing chemicals. Cable management lines use high-grade polyurethane jackets to resist abrasion, oil, and ozone exposure.
For electrical systems, our solid-state frequency converters are built with isolated gate bipolar transistors (IGBTs) from leading manufacturers. Multi-processor control units monitor system performance and safety features. Standard protection functions include overcurrent shutdown, phase loss prevention, temperature monitoring, and overload limits. Our designs prioritize safety, longevity, and ease of maintenance.
