Posted October 19, 201410 yr Based on Liebherr HS 875 HD. More information and pictures: http://www.designer-...dragline_cc.htm. Another stunning beauty from Han.. I'll be building this one myself for sure. Some details from the page linked above: Length for transport, only A-frame + boom foot: 65 cm Height superstructure: 18 cm Width undercarriage: 21 cm Length boom (3 sections): 92 cm Height with raised boom (3 sections): 98 cm Boom angle range: -10 till 80 degrees Weight: 2,7 kg (including 2 battery boxes) Lifting capability:250 gram (safe range for full PF operations) max 500 gram (heavy stress on PF operations) PF elements used: 5x PF M-motors2 motors for Swing 1 motor to Lift/Lower the boom 2 motors for decoupling the drums - Free fall mechanism [*]2x PF L-motors (Crawl) [*]2x PF XL-motors (Wind/Unwind two drum winches) [*]4x IR-Receivers (2 motors being connected to the same output) [*]2x PF Battery Boxes (1x Rechargeable; 1x AA cells) Edited January 31, 201510 yr by jantjeuh
October 19, 201410 yr I've seen it, but I don't know how to get pictures and links posted, but I've heared more people complaning about this. Can somebody tell me how to do this the right way?
October 19, 201410 yr Thats a rather funky looking crane, Again its the same story with the good old technic turntable not being the best for such an application
October 19, 201410 yr All his MOCs are awesome, in my opinion he builds with the perfect balance to have playable MOCs, I like his tracked machines.
October 19, 201410 yr Author Thats a rather funky looking crane Looks pretty close to the real thing: I like the BAM colours, very vibrant :) Better than boring standard construction yellow. Edited October 19, 201410 yr by jantjeuh
October 21, 201410 yr Stupid AT&T. I can't see the pictures or link!!!!!!!!! Might I suggest you change your Internet provider, I had trouble using those idiots too. They responded to me that "the internet provider hosting Designer-Hans' website has spam security issues". So we as customers can't connect to a Lego Toy website? I have since ( over a year ago ) changed to Verizon, no troubles at all. :thumbup: Edited October 21, 201410 yr by ritztoys
January 31, 201510 yr I wonder if it was possible to use less motors Edited January 31, 201510 yr by Omikron
January 31, 201510 yr 9 motors will drain 2 battery boxes VERY fast. So in terms of playability it is not the best decision. If I understand correct from the render some of the double motors are used in a symmetric way to gain double torque/speed on the same function. I would rather prefer using gearing and some asymmetry in the design than an extra motor. Edited January 31, 201510 yr by Omikron
January 31, 201510 yr I don't think you could remove any motors,the main body looks crammed. Edited January 31, 201510 yr by Alasdair Ryan
January 31, 201510 yr I can confirm that. A) the turntable is positioned right in the render. DBG sides needs to be on top. B) batteries do not drawn the rechargeable box very fast. On birthday parties the crane was in operation by kids many hrs without recharging. And, the recharging the rechargable box is done fast, much much faster then the AA batteries rechargeable. Ditching motors... Don't think so. Asymmetrical motor setup for the drivetrain will result in a 'twisted axle' (the one with the worm gears) for slewing. And, the motors for the freefall system do not run frequently. Althought. One could argue to skip the freefall system, then the motor count is 7.
February 1, 201510 yr Oh, I see how it works now. The whole "tower" is spinning around the turn table. Was that made to increase stability and to lower the stress on the turn table? Edited February 1, 201510 yr by Omikron
