General requirements. The overall structure of the aircraft garbage receiving vehicle is generally classified, including the car body and the lifting device, the platform, the stabilizing device and the walking portion.

In the section of the car body and the lifting device, in order to increase the safety of the maintenance and maintenance of the staff, a pole or other reliable safety device for preventing the falling of the car body is provided. In addition, according to the requirement that there should be no sewage in the ground in the airport, measures to prevent the sewage from dripping to the ground should be added.

In the platform section, the requirements for the carrying capacity of the platform are added, that is, the uniform load of ≥160kg. This value is estimated by the quality of one person plus one bag of goods, and the platform is added according to the MH/T6016-1999 aircraft food vehicle standard. The telescopic platform) has an overload capacity, that is, after 1.25 times the rated load, the sinking amount (elastic deformation) of the foremost edge is ≤50mm. The front end of the platform shall be provided with anti-collision hose. When the telescopic platform is fully retracted in the horizontal direction, there shall be no parts and other obstacles within the range of at least 300 mm directly below the docking area of the platform. This clause can prevent other parts of the aircraft garbage receiving vehicle from rubbing the aircraft during the docking process, and the 300mm limit is also to prevent the operator from observing the view when docking the aircraft.

Stabilizing device. Aircraft garbage receiving vehicles are high-altitude vehicles. In order to increase their stability, special installation stabilizers are proposed. When retracting and moving, the work should be smooth and accurate, without creeping, chattering, impact, etc., and the stabilizers should have locks. Stop function. At the same time, the aircraft garbage receiving vehicle should be in the fully stowed state when the vehicle is in driving state, and its maximum displacement should not be >5mm. This clause is based on the requirements of QC/T52 to prevent stabilizing devices from accidentally falling during driving.

Walking part. As part of the chassis, the standard first requires that the axle load cannot be overloaded, and the load rate of the steering shaft and the drive shaft axle load must comply with GB7258. The standard requirements for constant-speed driving fuel consumption, maximum vehicle speed, acceleration performance, and taxi performance are not subject to standard limits, but should meet design requirements. At the same time, the safety of the aircraft garbage receiving vehicle when docking the aircraft requires stable driving at low speed (≤5km/h), and it should be stable and shock-free at low speed.

Environmental requirements. This clause is formulated in accordance with national energy conservation and emission reduction requirements, so mandatory requirements have been established for emissions and noise of civil aviation ground equipment.

safety equipment. This focus has clearly defined several potential risk factors, increasing the requirements for reflective markings to increase their visibility during nighttime work and to prevent collisions with other vehicles due to light. In addition, the standard also increases the interlocking function between driving and work.

Control device. In order to prevent the operator from misoperation and the aircraft garbage receiving vehicle from malfunctioning during driving and operation, the operator can find and take effective measures at the first time.

Hydraulic system. This adds to the requirements for hydraulic cylinders, tubes and fittings.

Emergency device. This item is designed to reset the vehicle and remove it from the scene when the vehicle fails to travel or work. The vehicle should be equipped with at least one manual or electric emergency device.

stability. This item is based on the general requirements of ENl915-2:2001 Aviation Ground Support Equipment Part II: Stability and strength requirements, calculation and test methods, requiring aircraft garbage receiving vehicles to be in the worst case conditions and 1.2 times anti-tip torque When tipping the moment, it should withstand a wind speed of ≥75km/h. The worst case condition is that the stabilizer is lowered, the car is unloaded and lifted to the highest, and the boarding platform is fully extended.

reliability. The operation and driving reliability test items were proposed for the operating mechanism and the traveling mechanism of the aircraft garbage receiving vehicle, and the reliability test requirements were clarified.
