Pushback tractor is a truck used to push the planes around the terminals to avoid damaged caused by picked up debris from the ground by the planes' engines. These vehicles are low profiled and very heavy (up to 55 tons or more). Companies which produce these vehicles insist on using them to pushing the planes all the way to airstrip to save air petrol and to reduce pollution. Refer to google for more information.

Tech sheet:

Length: 325 mm
Width: 115 mm
Height: 100 mm

Weight: 916 g

Speed: 0,16 m/s
Turning radius: 600 mm

I used following power functions' parts.

2x PF Medium
3x PF Light
1x Cable 200 mm
1x PF IR (Both channels occupied)
1x New type battery box

I build this truck when I had seen some photos of the airfields. I also wanted to use my new white bricks and take a break from telehandler project.

Functions:

The vehicles is driven by rear axle only. Steering is performed by medium motor with double reduction.

Appearance:

MOC is very simple but I tried to make it look as nice as possible. I don't have many white bricks though but I hope you will enjoy it. Check the gallery!

I like that building style...with tiles and curves!
Windshield is great.
I don't like that vehicles, I was thinking about building one, but they just don't work for me!
I am glad to see you build it.
Did you base your design on specific tractor model?

Now you just have to build appropriate scale plane :tongue:

I don't know. These are the only 4 wheels I have so I can't even make a trailer.

Very nice and functional MOC. I like the fact that it is so smooth and that you managed to put the motors in this compact vehicle.
Great work!

Looks great. I always liked the appearance of these pushbacks in real life, and your model captures the look very well.

That's one excellent model! Nicely compact, great detailing and finish.

Now build a plane to fit it :P

It's really nice. I've seen those before at the airport. I left you a comment and 5 rating on your youtube vid. :)

I was curious, did you setup center steering so that it can drive straight?

Unfortunately not. It would have been perfect if I had micromotor but I had to use the medium motor for steering with double reduction thus resulting in no free space for centering the steering. I would have been able to add a  3 piston engine dummy also :(

Thanks for the comments! I'm right now coming to an end with 11 motors Telehandler!

I am disassembling the truck today and I will share photos of interiors with you guys:)
