[MOC] Knuckle Crane Truck RC with Pneumatic

[MrTekneex]

Hello guys!

I present to you my last Moc, fully remote controlled, with pneumatic system.

2878 pieces, 5 M-Motor and 2 Xl- motors that control the following 9 functions:

- drive

- steering

- stabilizers (one control the pump, the other control the valve)

- knuckle

- crane (raise, extension, rotation)

- dump

Other functions:

- fake v6 engine

- door with handle working

- tilt cabin

The red command of the remote control changes the function of the 3 black commands: in the first setting they controls the pump, the valve and the dump, while in the second setting they controls the crane (rotation, raising,extension).

The command of the knuckle is the same that control the drive; the function is switched when the stabilizers touch the ground.

Soon the photo with details ;)

Here the video!

Hope You'll like it!

Nice looking truck. Find the crane a bit strange but that might just be as its in the middle of the night. Looking forward to the video and more pictures :)

[rumpletump]

Cool

I like the cab and I like the dumper. I think the crane could use some panels to pimp it up and hide the beams and gears a bit more.

I too am looking forward to the video :)

I would like to see more pictures, although it looks nice so far!

Nice MOC! but i also agree that you should put more panels on the crane

[MrTekneex]

Yes, you are right about the panels. Unfortunately I had no more.

@ skriblez It 's true: The crane has this odd shape because so balances the weight

Here some pics :)

Some details

Doors open

Stabilizers

Under the dump

The pump:

The switching system (drive to knuckle using the same motors) via linear actuator

The LA that control the switching system and the valve

Some gears

The crane full extended

The infared unit and battery box

the engine

Nice Truck I like the functionality

[jantjeuh]

Nice MOC! Like the use of pneumatics for the outriggers. Have you considered using the 'Grabber Arm Claw' of 42006 for the claw? Or are they too small?

[Alasdair Ryan]

Nice truck,I think you should try and improve the crane more.

Amazing job! Do you really need a large actuator for the gear shifter?

Thank you! Yes, they probably were perfect, but I haven't them :(

Thank you very much! I think that the mini actuator don't have the necessary power to move the valve.

[jantjeuh]

Order them on Bricklink like I did? They're not that expensive :) Alternatively, buy the 42006 set - it's good!

Eh eh :) This Moc Was born from set 8258, 8275, 8110 and 8070. I promised myself to add any extra part :) (except power function) Edited September 21, 2013 by djshiver

Ehi guys!

This is the link for the video!

Awesome! Also, I meant it seems like you could just do a simple mechanical thing for the switch and valve instead of a large LA. Was that just because of not enough space for necessary gearing?

I was forced to use this system because I had to put the switch in the middle of the truck, because I had problems with the length of the wires. :)

Is there a way to get the M-motor off the end of the crane and down in the body more? It adds a lot of weight out towards the end of the crane. I'm interested in how to do this for a robot version of this we are playing with (only smaller).

Awesome truck. It sure required a lot of time for planing!

The function of the claw was the one that gave me the most problems.

In fact, my intention was not to put any motor at the end of the crane. I could not put it at the beginning of the crane because I hadn't the 32 axles (needed for trasmit the motion, because the crane can be extended).

In the body of the truck is practically impossible, because in the center of the rotating platform can pass only 2 motions (in this case raising and estension of the crane).

Maybe for your case you could just utilize the 32 axle :)

Thank you very much! Yes, between design and construction took me six months ;)

This should have been 42009, amazing job fitting all the functions in at roughly the same scale as 8258! Looks very professional, it could be a real set.

This is a huge masterpiece! :wub:

Good work!

Enjoy!
