One Micro motor is about 14 Euros... Pneumatics are more realistic and have some retro appearance. To tell the truth, I was thinking about that idea for a quite some time, but at the end I think that pneumatics fits better. Thanks for your interest, Ryan! Especially with your first post with interesting ideas. I am also very much into details about mobile cranes, analyzing PDF files etc.

I would like to see this model built. Waiting for Blakbird to make one!

Thanks for your reply, For the Steering: 4 Modes are already working! I like the crab steering the most! It is surprisingly easy solution, I will shown it once I finish with the outriggers. I have some good progress with the outriggers, unfortunately I will have to use another receiver and another 2Ms, Will shown them in a few hours.

I will have to experiment with that concept, efferman! I will present my concept tomorrow. I am so into extendable outriggers right now As far as I see now, I will have to order another M and Receiver just for outriggers Ahhh, it is so good to be on a vacation, I can use full day just for my hobby!

Ok I have answered on your crane topic, it should be 5 studs max in perfect case, including vertical bracing of the outriggers side-walls. Can you explain a little bit more on how to use one channel to: 1. extend the outriggers first, then extend the pneumatics second, when preparing the crane to operate, and 2. to retract the pneumatic first and then to retract the outriggers second, when preparing the crane to leave the site.

It is easy, but make it 5 or 6 stud wide, including bracing so it wont brake when pneumatics start lifting the crane. That may not be so easy. I am going to work on it tonight, too. OK, We will meet tomorrow with the results. If we come to the good solution, then maybe we can both use it on our WIP cranes.

BOTH. Look at the picture I have provided. This concept has mechanical extension of the outriggers (via gear racks and 20tooth gears), and autovalve for pneumatics UP-DOWN. So it is RC.

I would LOVE to have realistic RC extend-able outriggers, something like this: http://www.brickshelf.com/gallery/Zoli/6x6Ginaf/gcv024.jpg But I am very fanatic here about proportions from the PDF file, which I am using as a reference, and the fact that I have only one slot available on IR Receiver, otherwise I would have to mount another Receiver... I will think about it tonight and try to build concept to see how much it will break the proportions (Truck Cab would have to go much more forward)

I am always looking for a new outriggers concept. It would be perfect if one could invent fully RC outriggers, which are compact for 1:20 scale. This is RC and, IMO, the best so far: http://www.brickshelf.com/gallery/Zoli/6x6Ginaf/gcv024.jpg

I know many of you guys just love pneumatics so I will keep them! Mechanical LEGO brick built cylinder for luffing is still inevitable, sorry...I would love to have 16 studs long Pneumatic cylinder, too.

Thanks for your reply, Yes I am aware of all the things you have mentioned, I will try to incorporate as much as the scale allow. After all this is only a 20 studs wide carrier. I am not aiming for a better crane than hers, just the best crane of all that I have build. I would like that final model would be as bear as good as her is! Thanks for your reply No, this is 100 percent new crane, with new curved cab and new axles...everything is new, built from scratch! Thanks! Thanks for the reply, Yes, I saw it, it is a nice crane that has AWD, too. Mine is a little bit bigger with 24x43 tires (20 studs wide) To build 3 axle Liebherr crane is my dream, and this was my first after dark age in 2003 (don't laugh): http://www.brickshelf.com/gallery/milanma/Liebherr/nearly_finished_2.jpg

LIEBHERR LTM 1050 WIP I have always been a great fan of Mobile Cranes, particularly from Liebherr. There are quite a few Crane models which I have built so far, but every one of them had some major flaws, or just not enough functions. This is LTM 1050, relatively new mobile crane from Liebherr. The LTM 1050-3.1 has been designed as an economical taxi crane. The biparted swing-away jib and a large portion of the ballast are included in its 12 t axle load. The innovative crane cab provides an ergonomic working area with an optimised heating and air-conditioning system. The active rear-axle steering and pneumatic disc brakes increase safety and efficiency in travel mode. My goal is to create The Ultimate Mobile Crane, Technic inside, and Model Team outside, which could stand next to Jennifer Clark's great Demag AC-50: http://www.jenniferclarkbass.com/lego/images/ac50_1/ac50_1_threequarters_lrg.jpg Her model has all functions as mine, but her has only front wheel steering, and only backs wheels drive, and limited suspension. I don't want to use any non-LEGO parts, and I want to make ultimate axles, chassis and drivetrain, thin LEGO built luffing cylinder, and more...which will include: 6x6x6 All wheel drive All wheel steer - 4 steer Modes All wheel suspension RC Drive RC steer RC Outrigger Deploy RC Outrigger Up-Down RC rotate Superstructure RC Boom Luff RC Boom Telescope RC Hoist 4 steer modes: -normal - all axles steer to achieve minimum turning radii -crab - all axles steer the same -no swerve on back - only front axle steer -no swerve on front- only back axles steer Modes remotely controlled, I will use large 24x43 tires, they are perfect size for this model (regarding both proportions and aesthetics) Modeled after PDF from Liebherr site, exact Lego replica in 1/16 - width 20 studs And yes...it will have Pneumatic outriggers, remotely controlled. WIP OK, progress so far includes: chassis, outrigger boxes, axles, truck cabin and crane cabin and boom: I will post new progress as I build, and explained properly each segment of the build. Next is installing two XLs for driving, and its gears... Comments are welcomed.

Regarding steering: On Mobile cranes there are often multiple steering modes, in Liebherr cranes for example there are up to 5 different steering modes. Three modes are most common: 1 Front wheel steer (for road use). 2 All wheel steer (for best manoeuvrability). 3 Crab steer (for sideways motion).

Nice! Now we wait for you to do the same modification on 8043 excavator

Is there a difference between "Normal steering" and "Small turning cycles" as you described. I mean, it has two steering modes, not three, right?

Just search Mixer in BS. Here are the best results, aside from Bosman ofc: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=391918 http://www.brickshelf.com/cgi-bin/gallery.cgi?f=409802 http://www.brickshelf.com/cgi-bin/gallery.cgi?f=425043 Mixer (drum) is extremely hard to make, according to Bosman's experience. Read about it on his site.

Here is how this U joint works for me in a 3 kg Scania, tried it with a crane mounted on a back, cca 5kg total, it worked:

Because it is too large for the Excavator this size, and this smaller bucket has better movement range. Great MOD, Jurgen!

Awesome recreation of the Tumbler! It is extremely sharp-shaped vehicle and you managed to build it correctly!

Welcome to Eurobricks!

tomacwhite said... Slewing Incredibly slow and a loud draining sound from the motor as it struggles to rotate. Movement is slow Left track Works OK Right track Incredibly slow and laggy, with a draining sound from the motor Main arm (dual actuators) Raising: So slow it virtually doesn't move. You have to help it with your hand, then it works perfectly. Lowering: Works OK Central arm Raising: Again, incredibly slow with a loud draining noise coming from the motor as it struggles to lift the arm Lowering: OK Bucket Fine in both directions I built the same size excavator, with same, M motor powering this function, and it works flawlesly, It has enough power to push or pull the entire 3kg excavator on a kitchen table. M Motor is connected directly to the LA, it doesn't have any gears between them, so maybe there could be a problem. Also important, I am using new 7.2V 8878 battery. For the main arm, again direct connection between 2 Ms and 2 LAs, and I guess it works perfect..it can lift 430gr leather slipper (then M's started to slow down a bit) and on a half way starts tipping the whole body over. Ok...I am using 2 Ms, instead of one, but my arm is much heavier, and it can lift good amount of weight. Just trying to help comparing these two similar excavators.

Welcome! These ships are really something! Wow!

Welcome! Fenders are nice, so is the shape of the bodywork...nice use of the parts, there are very few gaps on the body (which somebody likes when it is a Technic car, I dont) Overall, pretty nice!

Happy Birthday, guys! Have a great time!

Welcome! Have fun!
