  1. I have build a dump truck withe the 8258. But my problem is That the linear actuator isn't strong enouth with a down geard XL motor. Is there a diference when I use two LA's? or are there LA's who where stronger?
  2. Hi eurobrickers This is what we will talking about here: a mini scale semi dump truck based on a Mercedes Arocs 6X4 and a solid tilting bed mounted on one 3 axle trailer. This time I decided to keep it small. My son asked me for something simple this time but fun to play with. So I do. I worked hard on the design of this little set. The smaller it is hardest the design is I found. I am however quiet happy with the end result. From the front view you can see I choose a contrasted color scheme for this truck. Regular blue frame, white cab and black to simulate the plastic covers and accessories of the cab. I place light, traffic signs, rear view mirror, antenna and gyro on the top. All we need to make it look good, as in real life model. The top view show the roof treatment. This part was particularly hard to find. You have a discreet HOG, the security roof trap that opens and two small panels to finish the roof line Viewed from the back you can see I managed a space for the rear window, exhaust pipe, spare wheel and a toolbox. I do not forget the back lighting with one projector but also rear stop and traffic lights. The 5th wheel is a simple pin connection. I found another system (mechanical lock) but it doesn't match perfectly the scale of the model so I decided to remove it. But there is something more about this cab...it tilts and the doors can be opened showing the interior with two seats and steering wheel (not it is not operational ) The complete model is 36X8X11 cm. I am particulary satisfied with the proportion of the whole thing. Rear view of the trailer, same detail attention than for the tractor unit. You can see at first plan the locking system of the bed's door (simple friction pin). And here is the view of the railer once lifted. The mecha is dead simple: one linear actuator in direct link with the HOG place on a real ergonomic place. Few pieces, great playability. The trailer as also a retractable parking support with simple linkage command and lock point to assure it's stability. Here it is: But that's not all. I manage the all wheel one good ground clearance as my son play with it on it's bed (often by night ) and I realized a quiet complex pendular suspention on all axle. The system is based on Pippasseyeyoyo's one developed on his own semi dump truck. I just scale it down a little . Suspention in action. the first axle is rigid on the tractor unit So here it is...do not hesitate to comment it and any good idea to improve it is welcome. Steph.
  3. Hi! Finally, I present to you my dump trailer for Claas Xerion 5000 Trac VC, which I've built quite a long time ago and teased you with in this topic. My intention was to model a really cool looking trailer Krampe HP30 - a 3 axle offroad heavy haul trailer, which goes perfectly to Claas Xerion 5000 set. I didn't actually scale it, but scetches/blueprints on the official site were of good use. As you can see on the photo below, I made a fake front cylinder, which unfortunately doesn't exist in LEGO Technic, so I had to cheat and used a pulley system to lift this huge red bathtub. String drum located on the front of the trailer is rotated by rear PTO of the tractor. I used the fantastic Efferman's motorized remake, but an OOB 42054 model could run it too. The trailer is steered as well - BUT! - Shamefully, I've realized 1st and 3rd axle should be steered and not 2nd and 3rd like I built it. And that happened just an hour ago while editing the video! Oh well, I will have to put more effort in research next time Somehow, I missed the video explaining the steering part on YT. Steering is modelled by levers and works according to the angle between the tractor and the trailer. The 3rd axle has larger steering angle than the 2nd. As you can imagine, it has some play in it... All three axles are suspended (normal springs for 1st and 2nd axle, hard springs for the 3rd.) - I borrowed and altered axle designs from MB Arocs set. Tailgate raises automatically and is locked when the dumper is lowered. Here are some details, to make the trailer more juicy . ...and the underbelly - for those eager Technic fans, who can't do without . For the end, here's one with a little breeze and a video of course. I hope you enjoy it! You can find more photos here. Partlist and instructions here. Thank you for your attention and constructive criticism! Best regards, Miha

    [MOC] Tracked dump truck!

    Hi everyone, Here's an older MOC virtually no one has seen. It's my first fully RC model: Thanks! C&C PLEASE! BrickbyBrickTechnic
  5. Wished I posted this sooner......... When I was originally had the model normal it couldn't go over an half inch actual brick tile :(. Due to that I spent a long time modifying it to barely go through grass about as tall as the pretend sticker grill. This thing can go over an emaxx tire with its 2 not one xl motors and it had an l motor for steering (only do if your not using 3rd party tires) if using 3rd party tire use an xl motor for steering (I only had 2). I'm now building a a25E tanker to spray weed killer for me so I don't need to sweat to death. Since its super easy to detach the bed I could be able to switch the tanker and soon changed bed be swappable maybe? Picture from very first successful time. Version 1.0 instructions: http://bricksafe.com/pages/Voodu/42030-dump-truck-super-mod-instructions Video as just a quick demo of some average grass: This is what I'm building while doing Ingmar Spijkhoven 6x6 truck and stay tuned!

    [MOC] Dump Truck 8x8

    Hi to everybody! It's been a while from my last MOC...a year and 1 day to be precise ..well, how some of you already knew, the last year I bought and refurbished a home and that involved much of my free time. Now that the home is almost finished (I doubt that it ever will), a baby is coming ...that's mean that I'm planning to do instructions, but I don't know when. Now, that's my new MOC. It's a Dump truck 8x8. The scale is about 1:11. It was inspired by the Iveco Trakker (more than anything else to derive the dimensions), but the front grid ended to be more a beheaded batman logo. It's 8 wheels drive, moved by 4XL Motors connected to the wheels via a driveline, it has a differential per axle. 2 XL Motors drive the 1st and the 2nd axle and the other 2 drive the 3rd and 4th axles. This allow to have a virtual central diff and stress a bit less the drivetrain since the torque is splitted. A fake 6-inline engine is connected to the driveline of the 1st and 2nd axles. The 1st and the 2nd are steering axles via 2 PF Servo motors (one for each axle), with different turning radius and working steering wheel. The suspensions system consists in 4 live axles. Shock absorbers for the 1st and 2nd axles, with an anti-roll bar for the 1st axle, leaf springs for the 3rd and 4th. The Pneumatic system consists in 2 small pump driven by an L motor, that provide compressed air for tilting the cab, elevate the bed and to an hypothetical trailer. The lightening system consist in 4 PF Led, 2 in the front and 2 in the back for the headlights (and 2 extension wires). In the back there is a connector where is possible to connect lights of a trailer. There is even a winch in the front moved by an L Motor. It uses 2 SBrick that control everything, with the exeption of tilting the cab and providing compressed air to the trailer, that are actuated manually. It has openable doors (manually) that allow access to detailed interiors of the cab and it has a trailer coupling. The truck itself is built to be a base for several future MOC/MOD. In fact, tipping bed system a part, everything is contained in the chassis or in the side tanks. Weight and dimensions: Length: 93 studs (74.4 cm) Width: 29 studs (23.2 cm) (without mirrors) Height: 42 studs (33.6 cm) (without antennas) Weight: 6 Kg PF elements: 4 XL Motors for drive. 3 Servo Motors, 2 for steering and 1 for the tipping bed pneumatic valve. 2 L Motors, 1 for the pneumatic pump and 1 for the winch. 4 Led, 2 in the front and 2 in the back. 2 Li-Po battery. 2 SBrick. 4 20cm extension cables. 1 50cm extension cables. Pneumatic elements: 3 new long pneumatic cylinders 2 new small pneumatic pumps 3 pneumatic valves 2 M pneumatic cylinders A video is coming soon For more pics see: https://www.flickr.c...157667401525315 I hope you like it!
  7. Hi Guys, I would like to share my 8x8 medium dump truck with you. The target was to create 8x8 dump truck with 4 differencials in compact size with good driving abilities. It drives quite well, but due to large amount of gears, even XL motor have some trubles (wont stop, but you can hear little bit) while steering/climbing, but I'm happy with result, even view could be better. Some info: Propulsion: 8x8 by PF XL Steering: 8x4 by PF Servo (different angle for second axle) 1 Differencial for each axle Dumping by 1 M motor. No suspension, but thanks to flexible body, it can go well over obstacle. Opanable doors I'm sorry for really bad quality pictures, will upload short video soon. What do you think?
  8. My first creation, a European three axle dump truck. It uses 2 XL motors for drive, a servo for steering, L for dump and M for winch. I have decided to use 3 small turntables to create 2 pendular solid axles in the rear. I am happy with the result as this is not meant for heavy offroad use. It does the job nicely. No front drive, but oh well, goals for next model. I am very happy with the looks and color scheme and am hoping to find a good reaction from the community any questions about model I am happy to answer! Thanks for viewing!

  9. Based on 2013 Volvo FH16 6x4 its equiepted with ampliroll or hook lift system [media]http://www.youtube.com/watch?v=Bx8kawBn1Io[/media] Features: 1 M motor for steering 1 XL motor for drive 1 M motor and 1 linear actuator for the sliding/locking mechanism 2 Recievers 1 Standard battery pack 1 Flat bed 1 Wood log carrier 1 Open dump body? (i dont know how to call it) And openable doors Some more info: It uses 2 linear actuators for the jib but in order to make it work i needed to get more range so i used 2 tipper scissor style mechanisms to achive it. The sliding/locking mechanism uses a 12t to 24t because the jib flexes at the middle and its only got 2 fixed points this also means that it can only be powered when the jib is in the lower position something that real trucks use to prevent the jib from being accidentaly disengaged when its at the tipping position which could cause damage cause the body would fall down. The rear pendular suspension is achived by meshing a 12t to 20t gear so that they can rotate at the mesh (this is something i saw Zblj do in his videos) Things that can be improved: The rear chasis flexes cause it only uses 2 beams at the rear where the wheels are connected The linear actuators are too slow specially the sliding cause it uses a worm gear but i didnt have more room for other thing Since i build it i was told that in the real ones the 2 parts of the jib when they are in the hook position the jib has a contac point and then both of them move together so that the lenght of the point where it pivots to the point of the hook changes to have more power in the initial part of the lift http://www.brickshel...ry.cgi?f=527652

    Dumptrailer

    I made a dumptrailer (not yet finished) for the truck i've copied from Jaap. (Very nice truck btw). It uses 1 m-motor for the legs and 1 m-motor for the linear actuators. I must fix the lifting of the bed because it's a little bit heavy. hope you like it. Stephen
