Airport Crash Tender
About this creation
That's my new MOC. It's a Airport Crash Tender, a specialized fire engine designed for use in aircraft rescue and firefighting at aerodromes. The scale is about 1:14.

It was inspired by the Magirus Super Dragon X8, but I haven't created an exact copy of it (especially in the front).

It's 8 wheels drive, moved by 4XL Motors connected to the wheels via a driveline, it has a differential per axle.

The 1st and the 2nd are steering axles via 2 PF Servo motors (one for each axle), with
different turning radius.

The suspensions system consists in 4 live axles, with an anti-roll bar for each of them to avoid the lie down on one side (like the Unimog). I added another "arm" on the 3th and 4th axles for reduce side movements.

For reproduce the right wheelbases, I built this Moc with a unusual configuration. The 1st and the 4th axles are rotated. Practically the ball joints through which passes the drive shaft, for the 2nd and the 3rd axles, are directed to the center of the vehicle, on the contrary the ball joints of the 1st and the 4th are directed to the outside of it. In addition this configuration gives a positive caster angle to the 1st axle.

The Hydro-pneumatic system consists in a L pump without the spring that sends pressurized air to 2 "lungs" (one per side). Downstream of them there is a pneumatic valve (moved by a PF M Motor) that sends the air alternatively to the 2 water tanks (also these one per side for balancing). One tank is for the main water cannon an the other is for the bumper water cannon.

The MOC has an elevated extinguishing arm moved by 2 L motors. The nozzle can move up and down and can rotate via 2 PF M Motor. Even the bumper cannon could move up and down via 1 PF M Motor.

The lightening system consist in 2 PF Led in the front and 1 in the back for the headlights. The emergency lights consist in 10 PF Led connected to 2 PF switch (5+5). Those are actioned by a PF M Motor that give the flashing effects.

I used 5 non Lego parts. The 4 tanks (for air and for water) and an SBrick.

Other non technical features are:

- Openable sliding doors (manually) that allow access to detailed interiors of the cab. It has 4 seats, the areas around the driver's seat and the firefighting system controller's seat are detailed...using a bit of fantasy, especially for the firefighting area.

- The 2 hatches between the 2nd and the 3th axle can be open and give visibility about the water level.

- Also the complete side walls, placed above the hatches just mentioned, may be opened to access and refill the water tanks.

- Above the 3rd axle there are 2 hatches on the sides and 1 on the roof for access to the battery packs.

- 5 openable grids are placed on the engine compartment in the back. 2 are on the sides, 2 in the back and one on the roof. Those grids give access to the detailed engines compartment. There are placed 2 6-inline engines (like in the Superdragon X8). Using a differential they run with the pneumatic pump and/or with the drive motors. More or less like done by Sheepo on his Peterbilt (I think). In addition there are exhausts pipes with silencers and turbochargers, air filters with some pipes and radiators on the top. Even here I used a bit of fantasy, it was hard to find specific informations.

- Hook ladder on the roof, extendable manually.

Technical description:

Length: 126 studs (100,8 cm)
Width: 27 studs (21,6 cm) (without mirrors)
Height: 37 studs (29,6 cm) (without antennas)
Weight: 7,8Kg dry, 8,3Kg with filled water tanks

PF Elements

4 XL Motors for driving.

2 Servo Motors for steering.

3 L Motors, 2 for elevate the extinguishing arm and 1 for the pump.

5 M Motors, 2 for rotate and for move up and down the nozzle on the elevated extinguishing arm, 1 for move up and down the nozzle on the bumper, 1 for the pneumatic valve and 1 for the emergency lights.

3 Switch, 1 for invert one Servo motor (in the steering system) and 2 for the emergency lights.

13 Led, 2 in the front 1 in the back 4 in the front emergency lights, 4 in the rear emergency lights and 2 on the front bumper.

2 Li-Po battery for drive and steering.

1 Battery pack for all the other functions.

5 IR receivers, 2 for drive and steering, 3 for move the water cannon and for control the pneumatic valve.

1 SBrick (not really a PF elements but...) for headlights, emergency lights and pump.

Several (I don't remember the number) extension cables. Something like 4 by 20cm and 4 by 50cm.

Quoting Ario Gaviore che lavoro... incredibile. Bellissimo. Quanto ci hai messo a realizzarlo? hai usato qualche software e avevi gia i pezzi e sei partito da li? Si puň fare praticamente tutto con questi tecnhic oramai..
Grazie! Sono partito costruendo con i pezzi che avevo ed ho comprato quelli che mi mancavano man mano che sviluppavo il mezzo. Poi ho usato un SW per fare le istruzioni.

Quoting Techine Fan Very niceŁĄThe moc is very realistic.This is my now to see one of the best moc.But I have some Suggestions.I think you can shorten the car some, minus the length of a panel, let the car looks more harmonious.Also, I am also very surprised the design of the car lamps, such loss of the switch and lamp is very big, I think it is only a matter of time before, they are one of them would be bad, you can make a little improvement, trying to improve the design or delete this design.
It's in scale, if I reduce the length of 1 panel it will be no more in scale. I don't understand what you mean about the lights and switch.

Quoting Holly Van Keuren Hey I was wondering. Do you think you could build a model of Oshkosh P-15 ARFF? (Aircraft Rescue FireFighting) truck. Just curious! Again thankyou for the potential instruction list. If its not out by Christmas thats fine :)
Well, seen the pics on google, I think that it could come out a more real MOC than mine since it's really squared. Today afternoon this MOC will come back at home, and I'll start do do the mlcad file.

Quoting Holly Van Keuren Hello I love your design for the Airport Crash Tender. It is simply amazing. My husband is an Airport Firefighter and they use these trucks everyday, one of his favorites. Would it be possible to get a copy of the instructions for the build? This would make an amazing Christmas present. Thanks for your help!
Thanks for the kind words! I'll try to do my best, but I'm not sure to be able to complete them...and even more before christmas.

Quoting Matt Bace Wow! One of the most impressive Technic builds I've seen in a long time -- not just because of its functionality, but also because it looks. The shaping of the cab is absolutely perfect. I also really like that you incorporated anti-roll bars into the axles. With so many motors, I would guess that they are almost a necessity to keep the truck from tipping over.
Thanks!! I built it very specular for balance the weight. But the anti-roll bar are however necessary

Quoting Marin Stipkovic The only thing I don't like on this beast is the exposed M-motor on top. the rest is perfect!
I agree! And I have a couple of other things that don't fully meet me. But I haven't found a better solution.:-)

Wow, i've never before seen such a perfectly built technic firetruck. Airport firetrucks are my alltime favorite rigs because of their size and power they have. I still prefer the Rosenbauer Panther, but yours looks awesome in every detail. And it's so huuuuuge. Wow, wow, wow i'm really excited and impressed. Congrats!
