    [MOC] Mini Off-Road Crane

    it's so cool and playble for kids nice moc!!
  3. thnaks! yes, the boom lift and extend works with string,I got the ideas from brickshelf and modified to my moc, but I thought the most difficult issue is putting motors and gear in 3 studs space. I had spent so much time to overcome the problem. you mention that variable counterweight positioning sounds awesome and challenged, i had no idea how does it work I can't wait for the final result
  4. thanks for your comment, yes, all problem are exist the 1st and 2nd are the same problem, but I think it's not serious it's all about center of gravity, in the real crane, the boom set up behind the turntable, so did my brick crane. when the boom is in the high angle, the counterweight can balance center of gravity (even with the light counterweight) on the other hand, low angle(under 70 degree) must with a heavier counterweight to balance center of gravity and unbalance center of gravity could resulting in the superstructure would't slew well in this case I had already keep some spaces to add weight in addition, the lego turntable 48452 was too small to handle the superstructure, the lego 24121 is too big to fit in 17 studs (I think we need the new turntable part) I didn't solve the problem though I had add rollers around the turntable already the 3rd problem is the chaissis problem, it driven by only 1 axle(just like u42009), to solve it is add more driven axle maybe I would build my chassis version in the future sincerely.
  5. thanks you!! thanks you!! thanks you!! thanks you!!
  6. thnaks, the video would be add later, it drive and steer like u42009 I though the counterweight size is ok, but you remind me of the idea that I can add two little counterweight on both side thanks! i wll add a video later thanks, I also like the boom, it has a better-looking and work well
  7. Hi, as a crane fans, i'm happy to introduce my lastest building GROVE GMK5250L in scale 1:20 it's a revise version to my last crane project more accurate appearance and gear functions are more effective the 6 panel boom max can reach around 140 cm after extendend, and the crane high is 165-170 cm The angle of rise can reach 82 degrees, just like the real crane the counterweight is datchable Thanks for viewing and appreciate any feedback! 07/08/2021 the video added ps the spuerstructure operating in the video is speeding x2

    [MOC] Koenigsegg Jesko

    the function of door open is amazing!! wow!! WOW!! I'm speechless
  10. @nerdsforprez thanks for your kind words, so I upload some render pictures thought it still need some tweaked the boom total max length could reach around 150~155cm Work in progress.... need a lot of works For your reference thanks and best regards
  11. I used nylon line (ex: fish line, a normal 0.5mm fish line can against 15kg weight), and it raises and lowers by gravity You can see the inside mechanics´╗┐ picture from brichshelf if you're interested
  12. there are four motor in the superstructure, both side had a M motor and a L motor the actuator and the boom both are powered by L motors (use a lot gears to increase torgue) there is no gear in the boom so that it could reach the max length around 150~155 CM as possible. unfortunately the crane was KIA by my little 3 yrs Godzilla. I have to repair and rebuild the moc. maybe I will share some pictures when it done.
  13. Thanks, crane is my favorite technic series The moc test and fail over ten times It's very challenging and fun
  14. I had the same idea, so I built my crane in 2019 base on Grove 5250L the boom I use 3->5->7 and I was happy with the result
