i think there is something out of scale

Are you going to make a stick configuration for a peel grab?

[olaf9198]

Looks nice but the scraphead is to big for this mainboom

Are you going to make a stick configuration for a peel grab?

this is plan B

Looks nice but the scraphead is to big for this mainboom

i think the same

[Alasdair Ryan]

Do you plan on asking for help for Instructions?

I will PM you soon with some cool ideas on how to make your digger better.

Thanks for your ideas. one of them look like my old scrapclaw but unfortunately it is too big.

btw, the stick for the peel grab is finished.

hopefully i can get a 42006 for the claw parts in the next days

[efferman]

conclusion

works fine, only the rotation of the grapple is much to fast and needs a self locking feature

[Stephen Provoost]

very well done. Do you have a detailed photo of the grapple?

Happy Newyear

Stephen

[efferman]

sure

looks good efferman

looks like it is running better than the 8043

[Pedro Antunes]

Souldnt it rotate freely? Like hanging? So that it remains always vertically alligned... or would that not be possible to achive

[efferman]

no, it should not rotate freely. unfortunately the LA is rotating the grab when it is in its end positions. or it swings out of the vertical line

edit:

now the turntable is locked by a wormgear and the speed is reduced to roundabout 30 rounds per minute

i have made a ldd model of the undercarriage. is it possible to make it with closed Track?

@ efferman: Aanchir's Lego Technic Sprocket Wheel Template should work -- here it is on this Eurobricks post :

"LDD file (includes sprocket wheel wrapped in 6 tread pieces, straight length of 12 tread pieces, and green alignment tool)

User's Guide (step-by-step instructions, including tips on avoiding snags)."

From Aanchir's Brickshelf gallery, his User's Guide says:

"Hi! I'm Aanchir, and I created this template.

This template is for building models on LDD that require part 57520 (the small sprocket wheel) and part 57518 (the tread).

To use this template:

1) Download the file

2) Remove one or more of the tread pieces that surround the sprocket wheel so that it's no longer a complete loop.

I recommend removing one of the 60-degree tread pieces so there's a horizontal tread to connect to.

3) Connect as much extra tread as you need.

A chain of horizontally-placed treads is provided for you to use or copy.

WARNING!

Clips on LDD do not like to center correctly!

There will usually be a left or right offset, which can do a lot of harm if all of your clips are offset in the same direction.

The chain of tread pieces may not be lined up at both ends!

To avoid this, use the green alignment tool included in the file.

Place new tread pieces on every other pin, then place tread pieces on the pins in-between.

The alignment tool is entirely in green so you can use the "color select" tool to select all its parts at once.

If you need to use green parts in your actual model, feel free to select the tool and change its color to something a color you will not be using.

4) Once you have the length of tread you need, you will need it to wrap it around the other wheels of your model.

ALWAYS use the hinge tool to ensure the tread is wrapped snugly around each wheel.

It may help to paint the treads TRANSPARENT so you can see how they align in the grooves.

5) Some sets and MOCs will have some "sag room" on their treads, or will have wheels that have to be rotated to align properly.

I am not yet equipped to deal with either problem, but perhaps you will find your own solution.

If the alignment goes smoothly, the last hinge rotation will make your length of tread link back up at the ends.

Congratulations! You're done!

I hope this template proves useful."

[efferman]

thank you very much david. do you know if there is an ldd part model of the PF-L motor available?

[DLuders]

Saberwing40k made a LDD File of the Lego Power Functions L-motor and Servo-motor, and posted it here. You can see how he built up the equivalent pinhole locations:

They represent Bricklink Part 99498c01, "Light Bluish Gray Electric, Motor 9V Power Functions Servo with Dark Bluish Gray Bottom".

...and Bricklink Part 99499c01, "Electric, Motor 9V Power Functions L with Dark Bluish Gray Bottom."

[efferman]

again, thank you very much

[Stephen Provoost]

Hello,

It is a very nice crane, i love grapple cranes :)

I'm trying to make it grom your photos of I may?

Can you take some photos of the piece where the yellow arm is connected to the black one?

And also how the L motor fits the 2 la's :)

Thank you very much :)

Stephen

[efferman]

iam working currently at a ldd model of the uppercarriage, so you can see the drivetrain in detail. if you want pics from the second boom LAs please look here

and here pics of the connection between first boom and stick.

[efferman]

i have finished the uppercarriage. pleas ignore green parts, because they are placeholder for the PF-L motors or skip some connection problems. the booms will follow

undercarriage with tracks

http://www.brickshel...ewithtracks.lxf

edit:

i have stripped the ldd model, to show the drivetrain of the standard functions

red= track right

green= track left

blue= shovel

yellow= stick

orange= mainboom up and down

grey= rotation

Amazing as usual Effe, I love learning from your compact designs.

[Stephen Provoost]

Thank you for the pictures.

[efferman]

today i have built just4fun a small tracked thing. has anyone a idea what could fit on top?

Edited January 12, 2013 by efferman

[Alasdair Ryan]

Is it one of those pumps you make/crash in real life?

[efferman]

no, my thought during building was a snowgroomer, but in meanwhile iam thinking i switch to build something like this
