This is something I came up with after starting a build of wheeled excavator from scratch. My previous model had overcomplicated design of the chassis and used small linear actuators for arm movement which was pretty bad for a manual model due to the amount of cranking required. I also got rid of steering elements I often used in my previous builds as they are not that common anymore. The one of the arm controls use single lever for two arm movements - bucket movement and arm movement - this is made possible by differentiating the torque required for string pull with a wheel. The video shows building of the chassis and operation of this excavator arm prototype I'm planning to build a full excavator model on this, hopefully with full fledged instructions, but it'll take some time, so stay tuned if you like it. -
Hi there, Here is a MOC I have been working on during 2020. I just completed the instructions (available at Rebrickable), which was the occasion to give it the final touch. It is a one set MOC, made of only parts from the 42078 Mack Anthem. It features a wheeled excavator and a trailer: Features of the excavator: Steering with HOG from the back Manual stabilizers Front blade with mini-LA, controlled from the back 180° rotation of the turret Articulated boom, controlled from the turret (2 LA + 1 mini-LA) L6 fake engine in the turret, driven from the rear train (with differential), with a transmission going through the turret Openable cabin door and motor hood Features of the trailer: Tipping of the bed (via gear rack) In the end there are quite some parts left, but very little gears. Here are a few more detailed pictures: And a short video: Hope you will like it!
