Hi to everybody!
Yes I know, it's been a while since the last time.
Many things changed in my life in the last years, and between family, work, and maybe the lawsuit against Mould King, I lost a bit the passion and time for build new MOC.
But I'm still here, alive, and I wasn't exactly still.
So here my last creation, an Heavy Duty Tractor Truck.

Heavy Duty Tractor Truck

I started building this truck about 2 year ago and it was finished around February, just in time to show it at MEI 2024.

The truck has 4x8 drive with a virtual differential, since it uses 4XL PF motors connected to a single wheel each (3rd and 4th axle) and they are not interconnected. one of them also control a fake V8 engine.

The suspensions are independent for the 1st and 2nd axle, and the 2nd can be rised or lowered whit a pneumatic system.
The 3rd and 4th axles have pendular axles.

3 PF Servo motors control the steering, which have different turning radius between the axles and it have a working steering wheel.

There are 4 remote controlled functions (other than drive and steering).
3 of them are electro-pneumatic:
- Activate or deactivate the pneumatic compressor.
- Rising or lowering the second axle.
- Locking or unlocking the fifth wheel.
The 4th is only electrical, via a PF M Motor is possible to activate the windshield whipers.

The pneumatic sistem feeds even the tilting cab system, which can be activated manually, the suspended seats and the outlet to an hypotetical trailer (even this manually operated).
The cab is suspended and it has openable doors and them have handels and locking system.
As well, the front grid is openable. This give the access to the radiator and the refrigerant and whipers fluid tanks.

I used 2 BuWizz to give some juice to the truck.

I hope you enjoy it!

For the Administrators: Sorry If I broke some rules, I'm starting to get old!

It would take me two lifetimes to do something with half the parts, great job. I guess all the new frames will have been useful for your kind of MOCs.
