[MOC] MAN TGS 8x4 Tow Truck

[M_longer]

After nine months of building I'd like to present my latest model.

MAN TGS 8x4 Tow Truck with OMArS 120T recovery bodywork

It is based on various trucks, mostly on this

. This gave me idea for colour scheme.

And pictures of this Volvo were also helpful.

Unlike the yellow one, which was build in a hurry for contest, this tow truck has a lot more details, like opening doors and cab interior.

Whole truck is covered with stripes of reflective foil. Three rows on sides, and additional chevrons on front and back:

OK, we have talked over external appearence, now it is time for internal mechanics. And there's lot of it inside.

Model weigths 4kg, I decided to build solid frame without suspension. Due to its mass, it would not work properly.

In the inside are:

8878 battery, 6 PF motors, 2 micromotors, 4 PF switches, one 9V switch, 5 pair PF LEDs, 3 1x4 light bricks, 4 PF extension wires, two IR receivers, 5 9V wires, 11 pneumatic cylinders, 4 small pumps, one airtank, 6 pneumatic switches and one coffe cup.

Placed like this:

Front axles are steered by Servo motor, each axle has different steering angle, achieved with different lenght of steering arms. Simple and effective.

Single XL motor is responsible for driving whole model. It has no problems with mass of the model, even when it is towing something (W900 chassis weights over 1kg).

Main double winch is driven by single Medium Motor. Its rotation is speeded up a bit to match crane arm extending speed.

The crane arm is extended by single M motor trough linear clutch. Cluth provides additional protectnion for the extending mechanism, which uses chain links instead of gear racks.

Front winch is driven by single M motor. If you would like to build one, I have made instructions for it while learning MLCad.

Side winches are placed on both outriggers. Each is driven by single micromotor. It will not pull a elephant, but it works well with light loads.

The pneumatic compressor is driven by L motor, and is using four small 5.5L pumps connected to an airtank:

Speaking about pneumatics:

Six circuits in total, all using large cylinders:

Front outriggers use two for each outrigger:

Crane arm is raised by two cylinders, wheel lift is operated by single cylinder:

Steering hatches:

Blue - arm extending, yellow - main winch:

Black - front outriggers lowering, grey - front outriggers folding, yellow - raising the lightbar, red - front winch

Back:

Blue - crane arm rasing, red - wheel lift movement, grey - rear outriggers lowering

Compressor is powered via pressure switch. The switch has small pneumatic cylinder with rubber band connected to it. When the pressure is high enough, cylinder overcome the rubber band and turn the switch off.

Lights. Front and rear LEDs are powered directly from 8878 battery. Lightbars are powered from 9V switch placed inside the cab.

Ready to work?

So let's work:

And here you can see how developing of such model looks like:

Saw the video yesterday, love all the functions Also love how smoothly the pneumatics and PF functions mix together.

[KirTech LAB]

Incredible functionality!!! I don't know what i like more - design or mechanisms - both are perfect! And presentation is very interesting too!

[D3K]

Wow, it looks packed! And also very aesthetically pleasing! Very very well done model, can't remember having seen such a level of details on a tow truck of this style, so this is refreshing!;-)

[LEGO Train 12 Volts]

You've done an awesome work! The decals are the icing on the cake!

[MajklSpajkl]

Outstanding build!!! It's amazing how everything is so "studless".I really like that you chose pneumatics over LAs .

[AndyCW]

Holy cow!! This thing is great.

I had to laugh about the other thread and your entrance into it. Poor Horace probably feels pretty bad about that.

Uhhmm, you are talking about me? If so, yes, my models are included in Sariel's new book.

Yea, I was referring to you :) -- great job, and happy that you are in Sariel's book. As I understand it, it comes out in NOV, and I already bought a copy. Hopefully it should be arriving soon.

In one word super!!!!!

Are you going to make instructions for this beautiful machine?

No idea, so far I did not have time for making instructions of Volvo. But it has a lot of pneumatic tubbing and wires, and I am not skilled enough to make them in MLCad.

Anyway, Here is how it looks without body panels:

Wires and tubbing routing:

And split to modules:
