LEGO Technic Excavator Construction Toy 42055

Product Information

Note: I took the pictures outside in the garden this morning so they have a nice 'warm' tone to them.) Step 8 completes the model with the cabin, railing and other small stuff. The cabin is a little too small for a minifigure.

That's the theory anyway... It's a neat mechanism and it almost works. Generally, the 2x2s always exit the machine correctly but the 1x1s often don't. This is definitely a model that benefits from a video review but they are thin on the ground on YouTube at the moment. If I wasn't hopeless with a video camera I would have had a go myself.Bags numbered six builds the business end of the machine and this is the most time consuming of the eight bags, taking around 1.5 hours.

After 225 steps and about 3.5 hours of building the chassis and lower part of the body are complete. Bags #8 add the cab, bodywork, walkways, lights and other cosmetic details. Overall, the build time for the entire model is around 7 hours.

The build – Step 2

However, we still have not finished construction... At the end of bags #7 the model is functionally complete and can be tested and I urge you to do so because if there is any debugging to be done it will be more easily achieved now. After experimenting this morning, I found a simple fix for the latter problem which doesn't solve it fully but does improve things considerably: The driveline for driving, turning and the small conveyer belt are also connected with these parts. Here it’s more obvious. The parts don’t hold tight to the axle but can slide. This allowing some wiggleroom when lowering and raising the big arm. So, how does it work? Quite cleverly as it happens, but unfortunately the mechanism is buried deep inside the machine so is impossible to photograph without a major dismantling. (Yes, I should have photo'd it before finishing it, I know...)

Unlike the other three large Technic sets released this summer, this one is not based on a real-life machine. Its design is certainly influenced by real BWEs but it looks nothing like any that I have been able to find pictures of. Take a look at some images yourself and see if you can fine one.Light Bluish Gray Electric 9V Battery Box 4 x 11 x 7 PF with Orange Switch and Dark Bluish Gray Covers It's somewhat front-heavy so there is a bit of a tilt on the body which results in the vertical frame not being exactly vertical. It doesn't seem to interfere with operation though.

Basically, as the conveyer moves an 'agitating plate' is raised when the 1x5 beams on the belt pass under its end, which then drops again once it has passed. This in turn causes three axles under the input chute, mounted at a slight angle and spaced to allow 1x1 rounds to pass through them but not the 2x2s, to move up and down/vibrate as well. The 2x2s travel on top of the axles to their exit on the left (in the photo below) while the 1x1 fall through to theirs, on the right. You can see the ends of the three axles in the picture above. Nevertheless it's a very interesting machine to construct and operate and if you have the opportunity to build it for yourself I encourage you to so do. Perhaps you'll come up with some fixes for the other issues...Relatively cheap (yes, I’m dutch). In this set the parts are about € 0.06 cent per part. In for example the Porsche this is € 0.12.
