These 'Transformers' on the apron

Hydrogen fuel luggage tractor

The 'Hercules' on the apron

In 2021, China Eastern Airlines successfully developed the first hydrogen powered luggage tractor for civil aviation, filling the gap in the field of new fuel cells. The vehicle relies on a pure electric chassis as the carrier. In order to improve the safety and power of the self-made chassis, the drive motor control system of the precision tractor is also optimized, with a maximum traction capacity of 25 tons. The entire vehicle is equipped with cold and warm air conditioning, allowing the driver to always maintain a comfortable temperature for towing operations, without being affected by external environmental temperatures.

This car is equipped with front axle leaf springs and independent suspension with cylindrical shock absorbers, as well as other hardware such as dual track front disc and rear drum brakes. The side of the car body is equipped with a micro motion docking device with independent performance for easy traction operation.

Hydrogen powered aircraft water vehicle

The porter of nature

This is an aircraft water tanker designed to replenish all the domestic water for passengers on the flight. It adopts the first domestic hydrogen fuel exclusive chassis structure, and can travel over 300 kilometers with just 5 minutes of hydrogen refueling, which is both convenient and environmentally friendly.

A large capacity carriage can carry several tons of water, which usually appears next to the plane after all passengers have left the plane. Drinking water is transported to the plane's clean water tank through a slender pipe. The water supply system is located at the rear of the vehicle, and the entire water tank is made of stainless steel plate. It adopts a high-power water pump, with a water flow rate of up to 180 liters per minute and adjustable water pressure, suitable for different water pressure requirements of various aircraft. In addition, it is equipped with an electric heating device for insulation, and there is no pressure in low temperature environments in winter.

Dongdong has very strict standards for supplying clean water for aircraft, and the water quality will also be regularly tested by authoritative institutions. Everyone can use it with confidence

Machine safety system

Unmanned driving

To take a closer look, China Eastern Airlines has developed and manufactured various special vehicles such as passenger boarding cars, passenger boarding cars with limited mobility, and aviation food trucks.

Aviation food truck

This car not only has safety and environmental protection, but also has strong load-bearing capacity. It uses a scissor fork structure for lifting and delivering meals, and the platform can rise up to 5.8 meters. It is suitable for various models such as 320, 330, 737, 777, etc.

The carriage can be lifted up in parallel through a hydraulic device, connected to the aircraft cabin door, and then the handcart containing food can be pushed into the cabin. Equipped with foot support grounding around to maintain vehicle stability, delicious meals can be delivered smoothly even in strong winds of level eight.

Boarding bus for passengers with limited mobility

Boarding bus for passengers with limited mobility-205075km/h

The car body is equipped with a square carriage, which is equipped with equipment for fixing disabled wheelchairs to prevent wheelchairs from slipping on the side. It is an "accessible" passage for boarding, making it convenient to park at a distant station. Without a bridge, disabled passengers, wheelchair passengers, and critically ill stretcher passengers can be transported onto the plane.

Its front end is similar to a regular truck, but the chassis is equipped with a "retractable" escalator. By adjusting the height of the escalator, it can adapt to different models. The larger the model, the steeper the slope. This car is suitable for various medium to large aircraft models such as 737 and 777 with cabin threshold heights ranging from two4 meters to 5.8 meters. It can ensure that passengers and staff from far away positions can get on and off the plane anytime and anywhere according to the parking conditions of the aircraft.
