This 42035 Mining Truck is one of the first new Technic sets of 2015. It is a small/medium sized set, and has a great looking design. Read on for the full review.

Be sure to check out the designer video by Markus and Milan (aka Grohl).

Box Contents

The box contains:

  • 3 x unnumbered bags of parts.
  • Sticker sheet
  • 4 x 49 x 20 Tyres.
  • Plastic wrapped instructions - 1 book for A-model and 1 book for B-model.

See the full inventory of 361 parts.

There are also digital building instructions available for this set via the free LEGO Building Instructions app. It's also nice to see printed instructions for the B-model.

Digital Instructions

The LEGO Building Instructions app currently only has 5 sets you can build, all of which are Technic, and all of which include the B-model. It didn't actually mention anything about this on the box (nor does it on 42036, I'm not sure about the other three sets). I would have thought they'd jump at the chance to promote an app to go with a set, like they have with others such as Ultra Agents.

They seem to be sticking to the smaller Technic sets, perhaps waiting to see if it pays off before investing extra effort in producing instructions for the larger models.

When building this set, I decided to use the instructions on my iPad to see how it worked. Some thoughts:

  • Lots of annoying animations when you are building sub-assemblies.
  • You can optionally display the parts callout to see what parts are in each step.
  • The standard touch screen controls apply to zoom/rotate.
  • There is some kind of bookmark button, but I couldn't figure it out.
  • It also has on screen 1:1 scale for the usual axles and beams, regardless of zoom level

Do I prefer this to printed booklets? No. Do my kids? Absolutely :) So maybe I'm just showing my age, but I like the fact that you can easily see multiple steps at once on a printed page, it gives a better sense of where everything fits in the scheme of things.


Despite this being a relatively small set, it actually contains a new part design - the 18945 Technic Panel 11x5x1 Tapered.

This part allows for a great looking angled tray in the back of the truck. The B-model makes use of them as a tapered bulldozer's shovel.


The build is pretty straightforward. It starts off with the base and the HOG steering, then the fake engine. The single piston, and engine belt look great.

The tray back is raised by turning a gear at the side, and can cleverly lock into position without falling down again. Curiously the front grill of the truck is connected via three blue 1/2 pins, but there is a hole for a fourth and actually one spare 1/2 pin. Go figure.


I think this set looks great. It is a small/medium sized Technic set at 361 parts, so doesn't come with a real lot of variety other than the new tapered panels and some of the increasingly common 3L Axle Pins.

To me, the digital building instructions seem to be an experiment on LEGO's behalf. Not quite fully investing in it, but feeling the waters to see how popular it becomes. I'm not sure if it is more or less effort to produce the instructions in the first place, but it definitely saves on printing costs.

You can now buy this set for US$29.99 or check other store prices and sales history here.

    This seems to me to be far below what I've come to expect for this price point ($29.99). And don't even mention the B-Model.

    Great review, though.

    If we refer to the scale of the model, this one piston engine would actually be the size of at least nine telephone booths and the piston itself would be larger than your typical round restaurant table for four.
    This and the painful lack of differential that makes the engine stop working if the load is uneven are the only faults of this awesome looking and affordable model in my opinion.

    There's no 1/2 pin in the fourth hole for the front grill connection because an axle protrudes halfway into the hole from behind.

    Nice review and cute set :) Not completely sold on the new panels though, they seem kind of superfluous. But hey, the more molds, the merrier, right?

      I'm not sure what to think of panels.
      They can make a model better-looking (look at 8043).
      But I also think it's not really LEGO. It's a kind of cheating: Let's use 1 big piece instead of LEGO building blocks

      I wonder why these panels show up. I can't imagine they are just designed for quite a small set where they could have had an acceptable workaround with a few beams and two asymmetric panels. So I expect some set this year where these panels do a much more fascinating job.

      BTW: I'm happy with the rectangular 5x11 yellow panel. I need one, but they are very pricey this moment.

    Looks good!
    If it had not that one-cylinder engine....
