The airport self-propelled multi-purpose vehicle is a device designed specifically for airport ground support operations. It integrates multiple functions and can flexibly complete multiple tasks. The following is a detailed introduction to it:
structural characteristics
- chassisUsually, a sturdy and durable special chassis is used, which has good maneuverability and stability to adapt to the complex ground environment and frequent operational needs of airports. Some vehicles are equipped with four-wheel drive or all wheel steering systems to improve driving and steering performance under different operating conditions.
- power systemDiesel engines are often used as power sources to provide sufficient power output to meet the energy needs of vehicles during various operations such as traction and lifting. Some new vehicles are also adopting electric or hybrid power systems to reduce exhaust emissions and achieve green and environmentally friendly operations.
- Multi functional homework deviceAccording to different job requirements, various replaceable or adjustable job devices are equipped, such as lifting platforms, traction devices, cargo handling platforms, etc. These devices are controlled through hydraulic, electric, and other methods to quickly and accurately switch functions.
- Driving control systemEquipped with a user-friendly driving control interface, it is convenient for drivers to operate various functions. Some vehicles are also equipped with electronic assistance systems, such as reversing cameras and automatic obstacle avoidance systems, to improve the safety and convenience of operations.
working principle
- Driving principleTaking diesel engines as an example, the engine burns diesel to generate power, which is transmitted to the wheels through the transmission system to drive the vehicle. Electric or hybrid vehicles use stored electrical energy from batteries to drive their wheels through electric motors.
- Working principleWhen different tasks need to be performed, operators activate the corresponding hydraulic or electric devices through the control panel or remote control system on the vehicle. For example, when using the lifting platform function, the hydraulic pump starts and delivers hydraulic oil to the hydraulic cylinder, pushing the lifting platform up or down; During traction operations, the traction device is mechanically connected to the towed equipment, and the vehicle provides traction force to complete the traction task.
Application scenarios
- Aircraft service guaranteeProvide refueling, water addition, catering and other services for the aircraft, and deliver personnel and supplies to the corresponding positions on the aircraft through the landing platform; It can also tow the aircraft to move within the airport, making it convenient for the aircraft to dock at designated positions or enter maintenance areas.
- Cargo handling, loading and unloadingIn the airport cargo area, it is used for handling and loading/unloading goods, transferring goods from ground transport vehicles to aircraft cargo holds, or vice versa. Its cargo handling platform can flexibly adjust its height to adapt to the height of different vehicles and aircraft cargo holds.
- Airport facility maintenanceWhen carrying out facility maintenance operations in airport runways, taxiways, and other areas, utilize the vehicle's takeoff and landing functions to facilitate the maintenance and replacement of lighting, signage, and other facilities by staff.
advantage
- Multi-functional integrationA vehicle can achieve multiple functions, reducing the types and quantities of equipment required for airport ground support operations, lowering equipment procurement and management costs, and improving operational efficiency.
- High flexibilityBeing able to quickly move and switch job functions in different areas of the airport, adapting to the busy and changing work environment of the airport, and responding to various security needs in a timely manner.
- Good safetyEquipped with various safety devices and auxiliary systems, it ensures the safety of vehicles during driving and operation, reduces the probability of accidents, and protects personnel and equipment safety.
limitation
- relatively high costDue to the integration of multiple functions and technologies, the procurement cost of self-propelled multi-purpose vehicles at airports is relatively high. In addition, later maintenance also requires technical personnel and equipment, and the maintenance cost is not low.
- High operational requirementsOperators need to be familiar with the operation methods and safety regulations of various functions of the vehicle, and need to undergo specialized training before they can take up their posts, which increases the cost of human training and management difficulty.
