At 4057 parts, 42082 Rough Terrain Crane has the most parts of any Technic set. You will probably need to set aside a few evenings to compete this Goliath model.
Read on as I complete my review and offer my overall opinion of this huge set.
New and rare parts
I have taken a more detailed analysis of the parts inventory for this set. While there are no new parts, there are two parts in a new colour and several rare parts.
Parts in new colours:
Rare parts that appear in four or less sets:
- Technic Panel Curved 7 x 3 with 2 Pin Holes through Panel Surface - Dark Stone Grey, 2 sets
- Technic Panel 3 X 11 x 1 - Red, 2 sets
- Technic I Beam 3 x 5 Thick [90° Offset Centre Beam Holes] - Red, 3 sets
- Technic Axle and Pin Connector Toggle Joint Smooth - White, 3 sets
- Wheel 56 x 36 Technic Racing Medium with 6 Pin Holes - Red, 4 sets
- Technic Beam 3 x 3 T-Shape - Red, 4 sets
The full inventory can be seen at Rebrickable.
Build Step 9
Build step 9 assembles the frame of the crane's superstructure and contains the main gearbox that controls whether the Power Functions drives the chassis options or the boom options.
Note that there is a grey ball with cross axle on the gear lever but this will later be hidden under the panelling.
Build Step 10
The Power Functions components are added to the superstructure in build step 10. The battery box acts as the crane's counterweight.
I used a figure-of-eight knot to anchor the string to the winch.
Build Step 11
The extendable, red boom and hook is assembled in build step 11.
Here is a view of these components prior to attachment to the superstructure.
And this is what the model looks like when the boom is connected. A figure-of-eight was used again to the anchor the string to the end of the boom.
There is a clever rope guide laying the string onto the winch.
Build Step 12
The motor and gearbox covers are assembled in build step 12.
Build Step 13
The model is completed in build step 13. Here is the cab.
The model comes with four prefabricated grey panels that joins together to build a roofless cabin.
I have applied the stickers to the completed model.
The crane cab has a non-functional lever to the right of the steering wheel and also a fire extinguisher is located in a bracket behind the cab.
The door has a clever way of pivoting open.
I believe that OK Lifting Services acknowledges Olav Kroigaard as the LEGO designer for this set.
Olav Kroigaard started [working for LEGO] in September 1987 as a LEGO Technic designer. After 12 years [he] changed to LEGO System and designed LEGO Sports, CREATOR, Batman, Spider-Man, and other LEGO licensed lines.
When the crane is slewed to the side the exposed V8 engine can be seen.
Throughout the model are small safety stickers that warns people not to get their hands or bodies caught in the exposed gearing. I am not sure whether they represent real-world safety stickers or they are there to warn young people not to get their small fingers caught.
Either way, the stickers provided the same function.
OK branding has been added to the engine and the white oil filter has a sticker.
The rubber tyre at the rear operates the four-wheel steering.
Whether this is a draw back or not, all the Power Functions are driven by one L Motor housed in the crane superstructure. As a result, there needs to be some clever gearing to enable you to operate each particular powered feature. There are four gearboxes in this model: two in the crane superstructure and two in the chassis.
The switch on the battery box has been modified so that polarity can only be switched one way.
The principle gearbox is on the top-left of the crane superstructure. This determines whether power is directed to the chassis (left) or the boom (right). Earlier you saw that the gear lever had a grey ball with cross axle. Here you can see that the lever is controlled using a red selector.
The boom gearbox has three options: boom up/down, boom extended/retracted, and winch hoist/lower.
I cannot figure out why there are two rubber bands just next to the battery box. They do not perform any function.
Edit: It would seem that the rubber bands provide friction to the hoist and boom-extension functions when these options are disengaged.
Down on the chassis are two gearboxes. The gearbox on the left-hand side operates the slew ring. There is also a small locker for a toolbox and set of tools.
On the right-hand side of the chassis is the gearbox for the outriggers. A locker contains a box of rigging chains. It is possible to extend/retract the outriggers while the crane is slewing.
There are a few really great features. One of the best designed features is the rope guide just above the winch.
The two grey wheels slide back and forth on the 5M axles and this effectively, and neatly, lays the rope onto the winch.
The outriggers are really strong and could lift the crane clear of the ground. However, configured the way they are, they do not lift the wheels up because they are too short.
The outriggers need the four 6x6 pads under their feet otherwise the outriggers won't reach the ground.
The outriggers are very slow to deploy. The price paid for their strength in being capable of lifting the model clear of the ground is that the gearing down of this feature makes it incredibly slow.
In the real world, deploying outriggers is very slow; however, I'm expecting this slow feature will be frustrating to some people.
You can see the detailed wheel hub here.
The drive train for the Power Functions to the chassis goes through two sets of small 12-toothed bevelled gears. Here are the bevelled gears above the slew ring.
And here is the bevelled gears immediately below the slew ring (this sub-assembly is upside down in the photo).
I just hope these small bevelled gears are up to the task they are put to.
This set includes lots of red Technic parts in the crane superstructure. Some of these parts are rare and will appeal to Technic and Mindstorms enthusiasts.
While not specified in the instructions, the chains used to lift the grey pre-fabricated panels can also be utilised to secure the hook.
The boom does not lower down to a horizontal position. This is the lowest it goes.
I wanted to view this crane alongside 42009 Mobile Crane Mk II.
Admittedly, 42009 Mobile Crane Mk II's boom is not fully extended - it has been displayed at quite a few LEGO shows and the mid boom section has jammed - this image shows the sheer size of 42082 Rough Terrain Crane against the yellow crane from 2013. It is refreshing to have a modern Technic crane that is not yellow.
Finally, here's a bird's-eye-view of the crane. I needed to rig a special backdrop as the model would not fit on my regular photographic backdrop.
I have enjoyed building this model. Having the parts separated into numbered bags made the building process straight forward and ensured that the eventual building outcome was error free.
This is a solid, sturdy crane and the Power Functions operate easily and smoothly. However, they operate a bit slow due significant gearing down.
40 Years of Technic Cranes
I saw a post made a few hours ago by a friend of mine that made the connection between 42082 Rough Terrain Crane and the original Technical crane set of 1978 - 855 Mobile Crane. The post implied that 42082 Rough Terrain Crane celebrates 40 years of Technic cranes.
Here is my 855 Mobile Crane that I received on my twelfth birthday. For sentimental reasons, it is truly one of my favourite Technic sets of-all-time.
You can see how far Technic has developed in forty years.
