Milan Posted October 28, 2009 Posted October 28, 2009 Hello, This is my old Backhoe, machine that I really like because of its versatility, and because it is so tricky to build in Lego, due to size limitation. It was my first creation since dark ages... Since I am working right now on new PF version of Backhoe, I want to present this first, older version. Real machine (that date version) Old BS folder with this machine HERE It has 12 pneumatic cylinders, powered bu motorized pump in controller. It has 2 motors in tractor unit. One for drive and one for steer. It is very basically built, without much attention to detail, and realism. I just aimed for JCB 3cx. Loader unit is controlled by hand controller, as well as driving the steering the tractor, while backhoe is operated via 4 switches, placed where steps should be. It has, unfortunately, wooden wheels, back then I did not have Power Puller giant wheels. It has very slow drive, but it can carry all of its weight, loader and backhoe worked well, but doubled cylinders often rotated in both directions. It was a good training for the machine I am working on now. NEW one will be RC JCB 3CX, with 8 LA's and 2 new rechargeable battery boxes, as well as RC speed remote controller, and very detailed, with Power Puller back tires, 24 studs wide. I will present it here in a few days. Quote
kondzios230 Posted October 28, 2009 Posted October 28, 2009 Very fine loader- you hide a lot of functions in not big size, but in my opinion non-lego wheels should be banned ;P kondzios230 PS:When you send me photos of your axle? Quote
Anio Posted October 28, 2009 Posted October 28, 2009 (edited) I like your MOC. Especially the mecanism with the rack (a bit like 8868) Edited October 28, 2009 by Anio Quote
Jetro Posted October 28, 2009 Posted October 28, 2009 The outside looks really nice. Some pics of the inside would be cool Quote
vmln8r Posted October 29, 2009 Posted October 29, 2009 Very cool 12 cylinders!? Impressive, can't wait to see the updated version. Quote
Paul B Technic Posted November 2, 2009 Posted November 2, 2009 I really like what you have done with this :) Quote
Milan Posted November 4, 2009 Author Posted November 4, 2009 (edited) Thanks for the comments, guys! Pictures of the inside are not possible since it is destroyed... I am very close to complete new version, which is coming together very nice, looks great and functions are working very good (that actually took most of the time). I am working at the CAD files at the moment, to show how some of the internal works. Final order should be here tomorrow, so I will finish it very soon and present it! kondzios230, you have a PM!

Jetro Posted November 4, 2009 Posted November 4, 2009 If you can do Pneumatics with LDraw, then you should have a look at the competition that's running at TechnicBRICKs (and if anyone else knows basic LDraw they might want to have a go as well) Quote
