Stage 5 Half Way

This is half way through the build and the end of the first book of installation instructions. I think the basic undercarriage is finished and next we start on the crane itself. It has taken about two weeks so far, so it should be finished by the middle of November.

Half Way Point

Note the ruler to give a better feeling for the scale of the model. The red pointer will be used to select which way the crane turns. There is a similar selector on the other side that will be used to raise or lower the support legs at each corner.


Stage Four

We are now on page 284 of the build and things are getting more and more complicated. I can’t believe this will work when I’m finished.

Top View

Now the model is standing on it’s legs and the main crane turntable has been added. Click on the photo to see a bigger photo.


Engine View

The main engine has also been fitted and you can see the pistons in the V8. The white tube is the exhaust pipe.


Stage Three

This is the model at stage 3 of the build. It is 43 centimetres long and 26 centimetres wide, so getting quite big. But I am only a quarter of the way through the build.

Side View

As you can see it nearly fills our kitchen table. It is upside-down in the photo as it would normally sit on the four red pads at each corner. Click on the photo to see a bigger image.


Top View

This view shows how complicated it has been to build so far.


End View

This closer view shows how many cogs and gears are used. When it’s finished the wheels will fit on those turrets sticking out.


Stage Two

After 130 pages this is the stage 2 result. We can now get an idea of how complicated this model will be.

Stage Two

This is the top view of the crane after a week’s building. Note all the cogs!


Left End

This will be where the wheels connect and these are steerable with a differential drive.


Top View

Very complicated gearing to allow both differential drive and steering.


Lego 42082 Crane

This is a huge model of a rough terrain crane with 4057 pieces. It will take weeks, if not months, to build.

Build Manual

Here are the build instructions, all 670 pages of them!


A Start

This is after 3 pages of build instructions.


Perfect Machine

This is the perfect machine built in Lego. I built this a few years ago and then passed all the components to my daughter.

Click on the image to see the original designer’s video. The aim is to turn off the red switch.

Lots and lots of fun.
