  1. First if all I totally forgot to post this model here on the forum, guess better late than never Now to explain a bit about the motives behind this model before I go into specific details. Counter on my youtube channel was nearing 10.000 so I wanted to make something trully special. I was not sure what kind of a model I want to make, a sportscar, offroader, construction machine, so the decision came to MAKE ALL AT ONCE. The model would also incoporate ideas from the last decade of Lego technic product to go along with my 10 years on youtube. Starting with the design, the front end is heavily inspired by 42083 and 41999. Notice the front wheels are from 42056. The first motorized function is adjustable front suspension inspired by 8297: The front end can raise by 3 centiemetrs to allow the model to negotiate rough terrain. Continuing towards the cab, which was inspired by 41999, we can pop up the hood to find a green colored 10 cylinder engine inspred by 42030: Cab doors are inspired by the doors from 42069, which open at the angle. Opening the doors you can find a full interrior with two adjustable seats andworking steering wheel: In the center of the cab there is a gearbox which movel lineary to switch between 3+R gears using a special mechanism. This emchanisem translates the sliding action into usable inputs for the gearbox: Going further back, there is a section holding the battery box and, orange lever and utensils on the left side. I will explain the function of the orange lever later. On the opposite, right side there are 2 M motors powering all the motorized functions. Notice the mysterious red lever which is used for switching motorized functions. Notice the pump used to power the pneumatic functions. There are also two electric switches to reverse the two driving M motors. If we continue towards the back, we can see there is a pair of linear actuators used to manipulate the container. The red lever switches power from one of the M motor between the adjustable front suspension and linear actuators. But not only can the linear actuators tilt the container, but they can also pick up and load the entire thing. To switch between tilting or picking up, the orange lever is used to lock the individual segments of the lifting arm. This function is inspired by 8052. The arm can reach out and pick up the container with ease: If we continue and look at the photo of the back side you may notice a PTO output along with a strange mechanism with rubber bands: Same motor that powers adjustable front suspension, linear actuators also powers the PTO output via 24 tooth clutch gear. Notice that the PTO output uses a CV joint in order to slide the axles into it without friction. The rubber band mechanism is used to hold the rear attachment. This was inspired by 8110 and 42054. Here is a sum up the functions of the model so far: 1. Motorized functions Adjustable font suspension Tilting of the container Picking up and lifting of the container Pneumatic compressor and storage provided by two air tanks powered rear PTO 2. Manual functions: 10 cylinder engine powered via rear wheels through a 3+R gearbox 3+R gearbox Steering controlled by steering wheels inside the cab AND the light on the right side of the roof Openable doors Openable hood Adjutstable seats Independent front suspension Solid live axle assembly in the rear - inspired by 42043 Features: Both front axles are at a positive cats angle, allwing the fat Porsche wheels to self-center Due to the immense weight, each rear solid axle is supported by 4 yellow very hard springs The 3+R gearbox is derived from my diagonal gearbox featured in the Dominator TRS Due to its framed design the gearbox provides a very rigid backbone to the model A 5 tubed exhaust seemed appropriate for the 10 cylinder engine I hope this photo helps you understand all the functions and features a bit better. Each color of the model's chassis represents a different module. Next we will look at the rear attachment built for this model. The attachment is multifunctional, combining linear actuators, pneumatics and 4-way switchbox to actuate all the functions: In total the attachemnt features following functions powered by a PTO via 4-way switchbox: Extension of the control arms via small actuators and a lever mechanism Lowering of the control arms via large actuators - inspried by 42009 Rotation of the arm Spooling up a winch which allows the arm to be used as a crane arm - inspired by 8258 Additionally there are 4 pneumatic function powered by the compressor and air stored in the two pneumatic tanks on the truck itself: Raising of the primary arm joint Raising of the secondary arm joint Tilting of the showel - inspired by 8043 Closure of the blue pneumatic claws - inspired by 8110 Some intersting facts about this attachment module: All of the penumatic functions + rope of the winch pass through the turntable. Rotation of the turntable is limited to some 350 degrees to avoid all those tubes and rope tangling up The structure of the arm with diagonal arms is inspired by crane arms Frictionless 8 tooth gears allow the white 16L axles to slide with ease while powering the two large actuators used for support legs The 4-way switchbox is one of my most complex and sense assemblies and it took me 2 days to design with support of LDD. Winch uses a friction pin to keep the rope from unloading when the winch function is off. The blue claw uses rubber bricks for better grip Combining the main model with the atatchment resluts in a model which weighs around 5 kilograms and is over a meter long! Some facts about the design, and build of the model: The whole model took me over 2 months to design and built, biggest challenging being the gearbox, container arm and rear attachment switchbox. A lot of care was placed into keeping all the functions working reliably with a limited power source (M motor) and safely with no gears skipping or breaking. The model uses around 16 universal and 3 CV joints to transfer the power to the suspension lifting mechanism, PTO, both steering sytsems and drive axles. Each rear axle is capable of supporting the whole model's weight, the weak point are the Power Puller tyres which sag quite a lot, especially on the third axle. Thanks to it's stiff gearbox, this model has one of the stiffest central frames I ever built allowing the model to be easily picked up by diagonal front and rear wheel without excessive flex. Gas canisters and first aid from 42069 are featured on this model The hood ornament is a bunny from a Lego Friends set This is my first model to use the white pneumatic air tanks for it's intended purpose. The model is covered with glow in the dark parts close to its edges, so its visible at night - useful when you are wandering around your building area at night A photo of the mashup's total of 8 glow in the dark bionicle claw/eye pieces: You can see the model in action in the following feature video: Finally I would like to thank you for reading through this massive post and for helping me reach 10.000 subscribers.
  2. 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?
  3. Edit: I completed the build. The 14th post in this thread has my comments on the build and how I re-colored some parts of the truck. As many of you know, for years I have been bemoaning selling my 8258's. Well I finally figured out a way to build the truck! I searched and searched for a good price (I was not going to pay $450 +) or someone to trade some stuff for an 8258, no luck! A couple of weeks ago while fiddling around on BaseBrick I found that I have most of the parts to build it! Wow, I can build the Crane Truck! I was only short a few parts (less than $20 on BrickLink), so off to get them... I now have all I need to build it, not all the absolute colors (a few different colors) but for me the 8258 is more about the build experience and the function. I am now pulling the parts from my collection of loose parts, tomorrow I build. A question I have is the necessity of all the modifications recommended by Designer Han at: modifications.htm There are 3 modifications he considers "critical" There are 3 modifications he considers "for improved playability" And 2 modifications for "looks" I am considering (strongly) the 3 he considers "critical" and the 3 he considers "for improved playability" and I really don't care about the 2 for "looks" iI am asking you to put your "way back hats" on and try to remember some of this stuff. My question is... Which of these modifications would you do if you were interested more in function than form? Thanks, Andy D
  4. As I am a big fan of Quattro & Co., I allways wanted to upgrade my models with AWD. For christmas my wife gave me the 8258 Crane Truck and - as most of you - I think that this was a milestone in the Lego Technic Flagship era. So after finishing it I immediatly started to think about the possibilities of upgrading this excellent set with 8x8 and other improvements. Here you can see now my progress so far: Added double wheels in the back added second driven axle in the back (as developed by BS-user arachnid) added most of the improvements of Designer-Han added opening doors added (first?) center differential added the first driven front axle See here the first impressions of my changes. ..... ...... . In the moment I think about adding a second center diff between the two front axles, but I am not quite sure, if that is neccessary for the playablity (torsion in the drive train and thus rubbing tires). I will test that. Updates will be posted here soon.
  5. I am working on some MODs for my 42043, so I build a copy of the front and rear axle of the Arocs and made a new chassis around them. In order to get a feeling for the correct proportions, I placed the 8258 cabine, front outrigger module and crane on this chassis and this is the result: Note that this is a mock-up, so none of the functions are connected to anything at the moment. What do you think, is this something worth pursuing? Should I focus on modding my 42043 or continue with this 8258 derivative? If so, what should its cargo be?
  6. Hi all, want to show to you my MOC. It is not yet final result, but it will not be much different from what you see here. The trailer will be ready soon. thank you.
  7. Hi everyone, today I am going to present to you my most recent MOC, it's an inverted trike with an old design, and motorized with RC and servo-motor. I built it to improve the way how a small RC takes curves at high speed and accelerates. So it has two wheels on the front, with drive and steering and a single wheel on the back. It also has full independant suspension. I'll make a video soon, just need to find the time :)

  9. Hi guys I decided to modify my 8258. First i added some of Designer Han's modifications. Then, I extended the truck by adding a 3rd axle to the end. The overall length of the truck got increased to 2 feet because of this. Next I moved onto the crane. I took out the string and added it to a removable winch at the rear of the truck. Then, i extended the crane. This took some time and many tries because the crane could not take the weight of the extension. Because of the extension the crane can reach a max height of 3 feet and can extend sideways 2 feet. I also added many cosmetic things like opening doors and a closed roof Fully extended With the unimog for size comparision Winch out Hope you like it! Please give me suggestions for improvement. More photos can be found on my Bricksafe account Also sorry for the bad pics. I was using my smartphone for them
  10. Good morning (at least in Europe ;-), i have a problem with the 8258: This picture (not mine) shows the crane completey folded, ie. the third arm section (the extractable one) is parallel to the middle arm section when the third arm and the second LA is completely retracted... The situation with my current build is different: if the second LA is completely extracted then the middle and the third arm sections make a almost straight line, and when completey retracted it is NOT parallel (as in the picture shown) but stays in an angle of about 30 degree or so... I have checked the instructions step by step but have not found any mistake... so: anybody out there with an idea what can be wrong? Thanks a lot in advance!
