"What's That Coming Over the Hill? Is It A Monster?" Well, YES IT IS! Wow, that's a big MOC! You can easily clean up the debris from the "Brick Truck Trials" with this loader! I like the X-16 engine, air compressor, and valve actuator setup -- all easily accessible with the hinged access panels. Great job, and thanks for sharing the pictures and video!
Wow, a MOC wheel loader so big that the Power Puller wheels look tiny. I never thought I would see such a thing!
This is a fine piece of work. The front bucket is truly enormous. You could entire official Technic models in that thing with room to spare. The X-16 engine is really a nice, original touch. I imagine you spent a lot of time on this. I'd love to see some more images of the X-16 including the crankshaft arrangment so I can imagine how it would look in motion.
It is interesting that you combined pneumatics and linear actuators not only in the same model, but used both on the main bucket controls. This should give you some good insight into comparisions. What do you feel are the relative strengths and weaknesses of these two options based on your use of them here?
Comparing pneumatics to LA's, i would say, pneumatics are stronger in this case, because compressor pumps with combination with new tighter tubes generate a lot of force. Linear actuators on the other hand are more rigid, because there is practically no flexible parts unlike compressed air in pneumatics. The problem with using 2 LA's to perform same function is in desynchronisation when stalled. Because no two LA's are same, clutch from one may kick in sooner than other, causing skewing. Pneumatics are self-regulating in that manner. A negative aspect of pneumatics is jerkyness, which is especially evident when lowering ehavy objects. Thats why i used a special air escape sytem, that limits aiflow out of cylinders, when the bucket is lowering. All in all, i think pneumatics are good when you are tight on space for mechanisms, or need longer reaches by combining 2 cylinders. LA's are good for operations, where precision, ireversebility and sturdyness are needed.
i spent arround a week building the model from scratch, improvising all the way. The hardest bit was making the bucket tilting mechanisem strong enough, yet able to allow high degree of tilting.
