[TC22] Compact tracked loader (finished, added more pictures and a video)

[Appie]

I saw this contest yesterday and as it happens I just started working on a MOC that fits. 

It will have 4 motors: 2 for drive, 1 for lift and 1 for tilt. 

The colour scheme plan so far is white with yellow. Above the hub will be the cabine. 

I am also planning to make attachments that are easy to switch: bucket, forklift and blade (currently testing the forklift in the picture), so the little fella will have more to do than just hauling dirt.

Without attachments it's less than 4000 cubic studs, with the biggest attachment it will be about 6500 cubic studs.

That could be very interesting. I'll follow this one with interest.

Nice to cram all those RC-functions in such small model! It's going to be a nice contest !

[Jurss]

That will be really compact motorised loader.

Looks cool! Excited to see where this goes.

[Appie]

Thanks all.

Current situation:

Finished the forklift setup and started working a bit on the bodywork. The grey axle sticking out on top will function as a way to turn on the hub so I can place a chair above the actual hub button. Next 2 things on agenda will be the loader attachment and trying to improve the position of the motor that handles the lifting which is currently sitting asymmetrical at the rear of the unit.

At first I thought I would cover that part with bodywork anyway, but now I am not so sure.

That looks great so far. I will be interested to see what it looks like when it is finished.

In fact real loaders of this type, mostly have some kind of extension at rear. Also "arms" are connected to chasis just behind the tracks.

Good point. I'll see what I can do to extend the arms backwards while maintaining the angle over the tracks in lowered position (the LA following the same line as the tracks pleases me esthetically).

I think due to the motors and gears, I won't be able to have the "dead space" (aka empty space above the bonnet) at the rear behind the cab and the mounting points of the arms like most real ones do.

Managed to put the connection point of the arm further back and up.

This is also gave me the space to put the m-motor below it and an added bonus of 3 studs more elevation on the arm

Also finished the bucket attachment, which was possible to make in a similar style as the forklift attachment.

The model is nearly finished.

 

The light in the middle on top functions as a turn-on button for the hub.

 

The MOC is also "Technic-fig compatible"

Left to do:

- Make an attachment for the blade

- Make improvements based on feedback provided here

- Make a video and some better photo's.

Front looks really cool with the cab and technic fig. I'm wondering about the back - isn't there any way to fit those two motors for the arms in somehow more compact way? Same thing is bugging me in my model that I'd want to have the rear lower than the cab as in real life loaders, but the drive for tilt is cumbersome.

I tried finding a way since Jurss mentioned it, but since it needs a wormgear for the tilt, which takes space to brace, the options became very limited. The only option I saw was to sacrifice the cab, which I chose not to.

Of the 7 studs behind the "hub power button", 6 studs are the motors, of which the tilt motor is resting on the hub, so I can't lower it further. The lift motor is resting on the drive motor for one of the tracks, so also can't be lowered. Placing them horizontally would have meant sacrificing the cab or making the model longer to accommodate the gears.

Made a video and some pictures for the finished model

 

Technic fig compatible :)

The light on top of the cab functions as a Power ON button for the hub's button located below the seat.

Three different attachments: loader, dozer and forklift attachments

 

 

 

 

Easy access to replace batteries:

Size of the model with the largest attachement is 7410 cubic studs (I rounded the height upwards to 19 studs, instead of using 18.5 studs).

Thanks for watching

Very nice movement and travel of the arm, very playable, congratulations on a great MOC.

Cool, looks fun to play with! 

[Appie]

Thanks guys

[1gor]

That should be official control+ set

[Thirdwigg]

Great job finishing the build. It functions well, and I like the white and yellow. The proportions give it a 8235 feel, which is great. 

[Maaboo the Witch]

Another model that uses the 42061 bucket. Hoping TLG see this and realize how many vehicles can use it.

[Appie]

Thanks everybody

Glad you like that as well. It was one of my favorite sets as a kid and couldn't help but think of it when I made this.
