LEGO Technic Multifunctional Aerodrome Tow Truck
About this creation
Hello All!

I am glad to present a scale model of non-existent Heavy Multifunctional Aerodrome Tow Truck in a technic-figure scale. The model is 77 cm long, 23 cm wide (without mirrors), 13 cm high (without exhaust), the weight is 4,45 kg. It took me about 1,5 months to create it.

Short video presentation:





The model have eight RC functions (seven useful + compressor) and manual controlled winches and lights (total 12 motors).

- moving (three XL-motors);
- independent front and rear steering (two servo-motors);
- lifting jacks (M-motor, eight pneumatic cylinders);
- cab lifting (M-motor, two pneumatic cylinders);
- front PPTO (M-motor);
- rear PTO (buggy-motor, slow output);
- winches (two L-motors);
- light (twelve LED pairs).

The transmission is very simple but rather reliable, one motor per axle with 1:3 reduction and differential gear.



There are no safety devices in winches because I want to get maximum power. So i provide a fast-unwind mechanism.



All mechanisms are covered with protective covers. The accumulators turns on/off on the top of the model.



There is a lightning switch in the rear part of the truck.



The model have lightning around the periphery.



Pneumatic is working due to four-pump compressor and RC valves.




The lifting jacks are the old-type large pneumatic cylinders mounted on the chassis.



Lifting cab function improves operator survey. It is very useful if we connect external mould-board.





The mould-board height is controlled by using PPTO.



Rear PTO is used for different attached implements. For demonstration Ive constructed an external boom-crane (the length 89 cm, width 22 cm, transportation height 19 cm, boom length 95 cm, weight 3,65 kg).







We need to connect crane to the main tow truck for lifting jacks activation.



Comfortable crane transmission creation was non-trivial task. Ive took all the controls out to the operator cab (every lever changes the direction of its own function).



Manual control allows to rotate tower (green axis), rise and extend the boom (yellow and blue axis correspondingly). At the small angles we need to rise boom with rear winch because actuators cant conduct such big load. Another cool feature of the crane is wheels hiding. It is necessary because the wheels prevent tower rotation.

Quoting Sander van Kreijl Amazing! Good job on making the monster lift, altogether 8 kilo's. Impressive.
Thanks! I like the lifting process too! Next time I should use more powerful compressor..
