[TC27] Crane Tipper
Thirdwigg posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I have not been building much in the last couple of months, so another Eurobricks Technic contest was just the invitation I needed to start a new project. While I'm not opposed to using the 49.5mm tires in a creative way like a tractor or construction machine, I have two trucks that have been sitting on my queue for about two years. Since neither has gone anywhere, I thought now might be the time to explore if they have any merits to continue. At the risk of making the same mistake I did with TC22 where I focused on two builds and couldn't easily decide on which MOC to submit, I am going to try this approach again. At least this time, they will have significant similarities and identical subassemblies. Crane Tipper This truck has been on my workbench for about a year after I found this picture, so I took the truck down and started working on it. After a quick draft, below is what I have (I know the rear tires are not right. I'm limited on my tire parts right now). It's straightforward design with RWD, front engine and steering, a tipper bed, and a center folding crane. The crane will be the limiting factor on this build, so I'll spend more time on that next. Below is a simple draft of the crane folding mechanism, but I'm not sure how I can make it work with the large gear rack and mount. After a little more building last night, I was able to rebuild the full chassis, in a way that will connect with the other truck. Hooklift Truck A hooklift truck is the second idea which uses 6 wheels, and is modeled after this truck I found a number of years ago. The truck will use the same front end as the tipper, but will have six wheels, and will have a hook lift on the rear. Front and rear steering will bookend the center drive wheel which will drive the front motor. Below is the first draft (again, sorry about the wheels). I think I am able to keep the same front chassis and cab between the two trucks. Right now the current headache is the hook lift mechanism. I would like to have the two function hook lift and bed tilt function, but it's causing some issues. I'll keep at it, and see what I can come up with. Below is the second draft to see if I can integrate the same front end for both trucks and steering needs. So far, it seems like I can. We'll see where this goes. Both trucks have some challening aspects, so I may just follow the path of least resistance. If both finish, I'll be happy to have two new MOCs. In the meantime, it's good to be building again. -
I finally did it, I've built a Volvo. It took me little more than a month to design, collect parts and build it, which is pretty short for my standards, I usually take (or loose) more time to fully complete a MOC of these proportions. The scale is, roughly, 1/20 and it has some functional features. Using LEGO power functions the vehicle can drive, steer, lift its 2nd drive axle, flash its beacon lights and operate the hooklift system. To be perfectly honest, not all of its features work the way I wanted them to work. The chassis was a bit small to incorporate all of these functions. I may design a new chassis at some point (more of that below) For me the highlight of this model is the cab really, getting the proportions of an FH right was a challenge, I had to make many compromises, choose the lesser of two evils. Of all truck brands, the Volvo just has the most complex design to replicate in the brick. But that is of course because a Volvo is the most pretty truck of them all after all. As I am employed at Volvo Trucks I simply had to build Volvo’s flagship. When Covid is over, I’ll drive it around the office landscape :). You may have noticed, the cab is not a square box, I spent a lot of time figuring out how to best approach the silhouette of the FH cab. It gets slightly more narrow higher up. The chassis is packed, I had to fit the battery box and two receivers in the cab, which is one of the reasons why there's no interior. Now, I'm sure some of you will most certainly have some suspicions about the feasibility of my hooklift system here... And they would be right! To be honest, the hooklift doesn't work all that well, lifting a container is a bit too much. It was only after I had completed the chassis that I learned about some sort of quality problem with those linear actuators I've used. But I think the fact that the very short leverage to rotate the hooklift may also have something to do with it. That of course was a consequence of the limited stroke of these actuators. This calls for the new longer actuators! ... However, that means I'll have to completely redesign the chassis... I have a couple of WIP pictures that I may share later. I hope you like it!

I am living in the Ruhr Area and would like to present you my new MOC as homage to my home city , the MAN TGS "Feuerwehr Bochum" That's the real truck Functions of the MOC: Drive: 2 PF-L Steering: 1 PF servo Lift: 1 PF-L on 2 long LA Lock & Arm: 1 PF-M The emergency lights including control is from www.BrickTec-lights.de and the sound module from www.rc-beluchtenungen.de It is controlled by 2 SBricks and the electricity comes from the LEGO accu box. The chassis and kinematics come from Efferman, it was only converted to the new LA and got a technic robe and the cabin is inspired by TheItalianBrick 's TGS 8x8. -
Mercedes Actros 3248 Hooklift
swissbagger posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello This will be my first post to showing one of my moc: Mercedes Actros 3248 Hooklift. I know a lot of people know this model, from my pictures on Brickshelf. I finished building this moc in early 2010, so it is 6 years old. Yes its very late to post here, but i think better late then never. The truck ist pf-remote controlled with 4 functions: - Drive by one PF-XL Motor to the rear wheels (2-Axle) - Steering by one old-style 9V-Motor (2838c01), second axle with transmission 16:20 - Hooklift powered by one PF-XL Motor - Boom look for tipping - loading / unloading controlled by one micro-motor (the eletric-cable can be changed for electric trailers or additional equipment There are also some manually fuctiones / features: - Two-speed transmission with gear ratio 1 : 1 or 1 : 3 - PF-lights in front and 9V-flashing lights on the roof working when the battery-box "on" - Openable doors by the drivers-cabine - Openable doors in backside by all three containers Scale from this model is 1 : 17. There are some more pictures in my brickshelf-gallery here: http://www.brickshel...?m=swissbagger1 And also one video on my youtube-channel: Feel free for your comments Kind regards Beat Schuler (Swissbagger)
