How does an airport tractor pull a plane?
1.: the main brake braking system components using MICO products in the United States, brake adopts full hydraulic double circuit, six accumulator, caliper disc brake system; parking brake spring brake hydraulic release, acting on the gearbox output shaft.2. steering system: full hydraulic power steering. Select the front wheel, rear wheel, electric four wheel or crabbing steering mode.3. emergency electric hydraulic system: once the engine fails, the electric pump will provide emergency steering power.4. electrical system: system voltage 24V, cab use breaker protection device, generator 80A----170A.
Four self carrying hydraulic support feet.6. automatic centralized lubrication system.7. the top part of the cab is equipped with three anti-collision switch, obstacle fast reverse landing to the bottom, to prevent the cab rises against the plane.8. when the cab rises, insert safety pins to ensure the safety of the maintenance under the driver's cab.
Low brake pressure alarm.11. throttle fault alarm.12. air filter plugging alarm.13. rear drive compartment and rear console.14.PLC control system and LCD display.
The front wheel is not up, using a drag rod front landing gear and Trailer together.Trailers are special vehicles that can pull hundreds of tons of 747. Its wheels are large and the friction coefficient is high. When towing the aircraft, as long as the trailer's horsepower is greater than the static friction force and dynamic friction of the aircraft wheel, the weight of the aircraft does not matter again.In fact, the plane is not difficult to drag. The airport apron is very rigid, and the friction between the wheel and the ground is not as great as it was supposed to be. I personally push 2 planes ^_^, small aircraft CRJ200, the parking brake is loose, few people will be able to push back.
The diesel power is very large, the aircraft does not brake, the wind can blow, and the wheels of the aircraft bearings are great, roller is quite classic,The plane will slide and insert the front landing gear turn pin. After the plug, the driver will have no way to control the front wheel turn.Trailers have wheels and mops, and mops are old-fashioned. Take a closer look, the wheels of the trailer are wide, and the steel plate of the trailer is very thick, so that the weight of the trailer is very heavy. Hanging mop can be said to be a big iron knot. The runway is concrete, so it doesn't rub much.
