Kladovec Posted April 17, 2018 Posted April 17, 2018 Hi, there. I´ve made something in LDD - dual retracting/extending outriggers for GMK6400? I´ve made it for nonsuspension version. It is compatible with it. But there are several cons: - in retracted position 1 stud wider - overall 1 stud higher - less rigid in extended position - five stud more in lenght - it will be problem with cables, which are routed through it in central section Pros: - six stud wider in extended position - bit closer to original crane Hope you like it.

emielroumen Posted April 17, 2018 Posted April 17, 2018 I did build the version without suspension and would be interested to see how your outriggers look in the finished model. Can you post pictures or make some renders? Quote

emielroumen Posted April 19, 2018 Posted April 19, 2018 Nice renders! Might get the parts together to build the sbrick version again with these changes. Quote

Kladovec Posted June 18, 2018 Posted June 18, 2018 (edited) Hi there once again, finally finished MKIII with dual outriggers, efferman´s actuator and superstructure. It´s really big crane when extended. I´m not 100% satisfied with it, there is much work to do with it. I have to improve lateral stability when boom is extended - some wheels or something, Driving and steering is much better with these improved version, than with suspended one. But with ballast on carrier is drivning and steering on its limit, better without it. http://www.brickshelf.com/gallery/Kladovec/gmk6400/img_20180618_162813_small.jpg http://www.brickshelf.com/gallery/Kladovec/gmk6400/img_20180618_164922_small.jpg More pics on my brickshelf gallery. Hope you like it. Edited June 19, 2018 by Kladovec Quote
Milan Posted June 18, 2018 Posted June 18, 2018 Guys, do not quote pictures on the same page. @Kladovec please resize your photos to EB's max allowed size. Quote
catdoit Posted June 20, 2018 Posted June 20, 2018 (edited) I tried to build GMK6400 using LDD according to gmk6400_1.2.pdf, which is the version full suspension on all axles. But one of the problems I encountered was that there was a brick on the top of the beam, which limited the upward movement of the beam. I was wondering if the shock absorber could work properly? The other thing is that the version I'm currently recommending without suspension, but I still want a perfect version with full suspension on all axles, bigger wheels, more reliable features. But I'm new to lego, and it's going to take me a long time to try. (sorry for my english) Edited June 28, 2018 by catdoit Quote
Saberwing40k Posted June 20, 2018 Posted June 20, 2018 The problem you're having is that the digital file does not actually show the suspension at rest, which would have the beams angled downwards. As shown in the files, the suspension is bottomed out, and can not be compressed any farther, but in practice this just limits travel. Quote
catdoit Posted June 20, 2018 Posted June 20, 2018 Thanks Saberwing40k. I still don't quite understand what you mean, maybe is LDD cannot reflect the actual situation, but so all right, I can bold use of the existing design before, and change some parts. Quote
afol1969 Posted June 21, 2018 Posted June 21, 2018 Hi all, It's glad to see that the grove crane still has some popularity. I'd now some time to create a quick'n dirty instruction from effermans' superstructure. Until now I could not build it to test the functions, because lack of parts. So it's possible that the instructions can have some errors. In the Ldraw file I have included the Lego actuator from motomatt, but could not integrate it in the instructions, it needs some modifications in the superstructure. So feel free to use and modify the instructions I made: https://bricksafe.com/files/afol1969/Instructions/efferman grove6400 superstructure.mpd https://bricksafe.com/files/afol1969/Instructions/efferman grove6400 superstructure.pdf Greetings Alex Quote
Kladovec Posted June 22, 2018 Posted June 22, 2018 Thanks Alex for BI. As I said, several problems has appeared. Some fixed, some remained. Lateral stability improved with added wedge wheels on both side of superstructure. Because of XL motor behind turntable, I cannot add another one on the back. Another problem has appeared - slipping 8t gear for turning superstructure. I think that´s becouse my custom heavy iron counterweight. But without it boom leans forward. Last issue is with powering effe´s actuator. With only one 20t gear for pivot point is not enough for lifting heavy boom, always slipping (at least my one). I must use two gears against each other - but when it´s going up it cracks sometimes. Little headache. Quote
JDL1967 Posted June 22, 2018 Posted June 22, 2018 (edited) In 2015 i build this crane. I posted pictures of it which are on page 17 and 18. I also added the axle on the front back then, to attache the hook. Now 3 years later, i want to build it once again. But i have seen that there are lot of mod's now. So i hope someone can tell me where i can get the total newest instructions of the whole crane, and the up to date partslist. Tnx.. Edited June 22, 2018 by JDL1967 Quote
afol1969 Posted June 26, 2018 Posted June 26, 2018 Hi, JDL1967, The latest instructions I've made was the version without suspensions an the boom modified with Firgelli actuators. Because of the big file size I've zipped the PDF file. You'll find it here for download: https://www.bricksafe.com/files/afol1969/Instructions/Grove6400-MKIII_1.1.7z And here is also the LDRAW file: https://www.bricksafe.com/files/afol1969/Instructions/GMK6400-Mk3_Firgelli.mpd The Part list you find in the instructions. Greetings Alex Quote

There are some mistakes but no big issues. Except in Step 10 the lbg Technic pin with Stop Bush collided with the black gear. I used a black pin instead. Currently modifying the superstructure to fit the actuator from motomatt. Quote

Hi, dunes, Yes, I've seen the error. Should be a simple black pin. Maybe there are more errors. It would be fine if you can update the Ldraw file with motomatt's actuator included: So I can make updated instructions and hope that I finally have all the parts to build the construction to find out the right building steps. Greetings Alex Quote
dunes Posted July 13, 2018 Posted July 13, 2018 (edited) Hey guys any tips on how to prevent the worm gears to slip over. Tried different mounting points on the boom and also build a different version of actuator. but still slip on the worm gear. If I help the boom to raise over a certain height then its not a problem.

Kladovec Posted July 15, 2018 Posted July 15, 2018 Hi, I make short video of my GMK crane. https://www.youtube.com/watch?v=cqdl2zl8zk0 Enjoy, hope you like it. Quote
Aleh Posted July 16, 2018 Posted July 16, 2018 It seems from the video your Y-arrangement does nothing. Hope my version of it helps. https://rebrickable.com/mocs/MOC-5740/OleJka/grove-gmk6400-mobile-crane-suspended-extended-lifting-capability/#comments Look - boom is bend the opposite side even! Better quality pictures are on bricksave. Quote
Kladovec Posted July 16, 2018 Posted July 16, 2018 It´s not correctly visible on video, but there is two Technic reel at the begining of the boom with locking mechanism. And you can tighten the rope at any lenght of the boom. When fully extended, this rope give me another 5 cm in height, with boom bend to the opposite side. Quote
catdoit Posted September 14, 2018 Posted September 14, 2018 (edited) I have finished the full suspension version with efferman‘s larger boom and actuonix linear actuator and some litter change. Thanks all designers ! Edited September 14, 2018 by catdoit Quote
