Hello all, I would like to present my latest creation, a Liebherr ECB flat top tower crane. Since the advent of the lunar earth sun orbit technic set, I saw immediate use of the base wheels and the grey rings. I always wanted to do a tower crane but never got around to do it. So now it became a reality. I did had to order a load of liftarms to make the the tower, and I ordered the 3X19 frames in dark blue grey. The build went rather smoothly, and resulted in a compact and more or less stable design, also using of a substantial amount of ballast weight in the base of the crane and in the boom counter ballast. Only the tensioning of the trolley wires was a real pain, also to make the system small enough to fit in the boom. It's still not quite perfect, but I'm happy with it. The crane measures 110cm in height and 135cm total length, the crane uses 2 transverse L-motors and 1 m-motor, and a powered up battery box. Example of the real crane My rendition: some close-ups: The Boom can be more or less easily dissassembled into 3 pieces, as well as the tower, and the counter boom can also easily dissassemble The counter ballast box has also 300g of bearing balls and the box is free hanging and easily removable with a mobile crane The grey boxes contain each 400g of small bearing balls as ballast. Rigidity of the tower is a bit of a problem, it suffers from a lot of torsion when the crane is slewing, the whole boom assembly is quite heavy. The cam half liftarm pieces allow for precise levelling of the boom Some small videos: Hope you liked it, comments are always welcome greetings -
Hello everyone, this model of a Tower Crane is made only with 1166 pieces and controlled with either smart device or physical remote. In order to all functions of that model, you get a complete overview in this article how to build and how to control this crane. You can find instructions here if you're interested in building this model. Summary of Functions & Features remote controlled with PoweredUp 2-way-gearbox to select between functions motorized hook, trolley and 360° crane rotation Hub with batteries as counterweight modular building with extendable tower Minifigure scale to fit City layouts openable cabin 83cm superstructure length 70cm tower height Impressions Electronic components The crane uses the newest PoweredUp electronics to power all the functions. In order to remotely control this model, a physical remote pad is not mandatory because the crane is also controllable with optional smart device and PoweredUp app. Shaped with some system pieces, the PoweredUp 2-port hub with batteries included fits perfectly as counterweight and is easily replaceable. Simply turn on the hub by finger press and connect them to either PoweredUp app or physical remote to let the fun begin. The official set 76112 Batman RC Batmobile offers all electronic PoweredUp components they are needed to control this Tower Crane. Trains (60197, 60198, 60336, 60337) from the City theme are also nice and welcome starting packs for electronics, because they all include one PoweredUp hub and a physical remote pad, which then requires only 2 additional medium motors. Controlling the crane Heart of the design and probably the most interesting part building this model is the controllable gearbox behind the cabin. Where motor A controls the movement of the trolley, the functions of motor B are selected through gearbox. The following configurations are possible when playing with this crane and two motors together: Motor A - Motor B Trolley - Hook Trolley - neutral Trolley - 360° rotation For the crane it is very important to have a neutral position for rotating the superstructure. In case this function is unselected, the crane can freely rotate and prevent from falling. This is a feature that can be also seen on real Tower Cranes. All functions are secured with clutch gears to prevent damage. The winch for the hook has also a safety mechanism included. This holds the cargo even when the function is unselected. Controlling the crane is thinkable easy. In the PoweredUp app it just requires a profile with two slider - one for motor A and one for motor B. That means that this crane is controllable with a custom profile or even with the available one from Batmobile. Keep in mind that controlling the model does not require a smart device by using the physical remote pad. Building the crane Splitted in separately parts, building this Tower Crane feels like constructing the real thing. Official strings (part 37597, 56823) are used in this model that are widely used with many lengths in other Technic sets. Of course you can use any other strings you want. The crane uses a modular building style where each part of the tower fits to each other. The inventory includes all parts that are required to build exactly one middle section, but it is still possible to omit and to create a crane with a lower height of the tower. Furthermore the height of the tower can be extended by replicating a middle section stacked to each other. A higher tower then requires a longer string for the hook for sure. The following inventory shows only the parts they are needed to build one more middle section: Made with Minifigure The cabin can be opened to put a Minifure (without hair or hat) inside. Since this Tower Crane is made in Minifigure scale, it matches perfectly each layout with Trains or Construction vehicles also in the City theme. Instructions Premium instructions for this model consists of 283 pages with high quality images and building steps very close to the Lego Technic ones. The instructions helps alot on how to connect strings and wires correctly. Following are some example pages to show the quality of instructions: Goal with this model was to create a Tower Crane that is not that big and expensive and buildable for everyone. Tons of hours are spent to experience with balancing and stability. The end result is pretty neat, the crane works just perfect but dont expect too heavy loads on it. The model fits all standards for easy building and color-coded components. If you're interested in building this model, you can buy instructions here and support me and my future work. Have fun with this Remote Controlled Tower Crane. Follow me on Instagram for updates and news -
Hello! After a few months of hiatus, some updates from my town :) Here we are the latest update of my construction site, with a more realistic tower crane, partially insipired by set #7905. Enjoy the pictures and I hope you'll like!

I have been working on a mostly rc tower crane for a few weeks (I don't have much time to build). And I wanted to show some progress. Because I couldn't shrink the size of my pictures I have them visible on my website. http://legomonkeyman.weebly.com/work-in-progress.html Hope you like it.

I am doing something I have never done before. A few days ago I started the 42042 A model again, but from a new set I had stashed. I built bags 1 and 2 and started bag 3. That means I had the driving base and gearbox completely built. Long story short, I decided (don't ask why) to build the B model instead. I took apart the gearbox and any bag 3 additions, but left the driving base alone, assuming that the driving base is the same for the A and B models. i have carefully gone through the instructions and the driving base appears to be identical for both the A and B models, so I sorted bags 4 with bags 2 and 3 and will start the assembly of the tower. My question is.... is the driving base actually the same for the A and B model? Or will I have to make changes to it? i have a few days of assembly on the tower base before I need to join the tower to the driving base and I would appreciate it if someone can confirm or deny that the driving bade is the same. Any response will be much appreciated. Andy D

Hello all!!! I want to show my funny MOC - Tower Crane Mk II (the first Tower Crane is a history now :) It has four RC functions (four M-motors) and it is telescopic! Its normal height is 145 cm. But it can rise himself up to 210 cm! For the counterweight i used three battery boxes with batteries Video: Thanks for watching!!!
