This is another 2-in-1 kit and it can build two different Mercedes-Benz construction toy vehicles. A large motor is included to allow some of the moving functions to work. There is also a new pneumatic part included to give a more realistic movement to the construction toy arms. It has 2793 pieces and LEGO recommend it for the 11-15 year old range however we believe it is best for the younger end of this age range.
In 1989, the LEGO pneumatic line was revamped, and a new cylinder and pump piece were introduced. The old cylinders and pumps were discontinued. The chief difference is that the new cylinder had two input valves now, which allowed both pushing and pulling without needing complex circuits involving the distribution block piece. The Generation 2 cylinders also had metal rods so that they more closely resembled real hydraulic cylinders.
The LEGO Technic fan community has always been as diverse as possible, consisting of kids building simple cars, teens assembling larger sets and adult fans creating incredibly complicated LEGO mechanisms. Designing a product that will be liked by an audience this broad sounds like a dreadful challenge, and one of the possible solutions is releasing a model bigger and heavier than any other set before. This way comes LEGO Technic 42082 Rough Terrain Crane, a gigantic model of 4057 pieces retailing for $299.99. The new crane becomes the largest LEGO Technic set to ever hit store shelves, but this larger scale is not without some potential flaws…

It would be totally unfair not to mention the brilliant design of the cab’s door. This is a sliding door made with an amazingly simple combination of short liftarms and pin connectors. When opened it slides to the back of the cab revealing the cab’s interior. A door like this is an absolutely unnecessary thing for a heavy motorised monster like this crane, but this is what makes it particularly special for the fans.
Yes, the only issue is that it is really expensive. While there is cool detail, authentic interior and genuine mirrored instructions, this might be out of the price range for many, but if you have the cash, then don’t hesitate to get your hands on one of the finest sets LEGO has ever released. Or this can make a great Christmas gift for your loved ones.
This kit, another great one for younger kids, is very lightweight and easy to carry - encouraging imaginative play with the completed model. It is very budget friendly too and is one of the cheapest LEGO Technic kits on the market. The twin-rotor helicopter measures around 4 inches high, 9 inches long and 7 inches wide when fully built. To play with it, kids simply follow the simple instructions which, according to reviews, will take most young kids a day or two.
I bought this set on its release day and I couldn’t be happier with it! Excellent write-up, and I couldn’t agree more about wishing that LEGO gave you some directions on how to test all of the gearing on such a complicated gear box before you start fully covering it up! When I got the motor installed and fired it up, nothing would move and I was not looking forward to taking apart so many pieces to find the mistake. Fortunately, I had simply forgotten to engage the upper/lower switch…once I flipped that, everything worked! Talk about a relief!
First of all I want to thank you a lot for your work with Technicopedia. It has become my primary source for Technic info, both for sets, parts and Technic development over the years. I really like your systematical approach, describing mechanisms for individual sets, as well as the description of categories and what sets and parts released each year .... Thanks again, and please keep up the good work!
W.O.W. This set is so detailed & intricate! The manual (one HUGE book!) is well made & will hold up over many builds & rebuilds. The box is gorgeous, the packaging convenient. There are lots of extra pieces, so no worries about missing something. The gears are smooth & slow, just like the real machine. Beautifully recreated, incredibly accurate, hours of building pleasure.
The Lego Group began in the workshop of Ole Kirk Christiansen (1891–1958), a carpenter from Billund, Denmark, who began making wooden toys in 1932.[7][8] In 1934, his company came to be called "Lego", derived from the Danish phrase leg godt, which means "play well". In 1947, Lego expanded to begin producing plastic toys.[9] In 1949 Lego began producing, among other new products, an early version of the now familiar interlocking bricks, calling them "Automatic Binding Bricks". These bricks were based on the Kiddicraft Self-Locking Bricks, which had been patented in the United Kingdom in 1939[10] and released in 1947. Lego had received a sample of the Kiddicraft bricks from the supplier of an injection-molding machine that it purchased.[11] The bricks, originally manufactured from cellulose acetate,[12] were a development of the traditional stackable wooden blocks of the time.[9]
At 10 inches high, 32 inches long and 7 inches wide, this is a massive construction ideal for older kids and adults. LEGO suggest it for the 11-16 year old age group. There are 2595 pieces, and it can also be rebuilt into a Mack Garbage Truck once completed. Users report spending over a week building this, so it is a great option to keep the user occupied for hours at a time. 

Lego Technic system expands on the normal Lego bricks with a whole range of new bricks that offer new function and building styles. The most significant change from normal Lego is that single-stud wide bricks ('beams') have circular holes through their vertical face, positioned in-between the studs. These holes can accommodate pins, which enable two beams to be held securely together side-by-side, or hinged at an angle. The holes also act as bearings for axles, on which gears and wheels can be attached to create complex mechanisms. Stud-less beams (studs are the bumps traditionally associated with Lego parts), referred to as 'liftarms' were first introduced in 1989 and through the 1990s and 2000s and increasing number of liftarm designs have been introduced over time.

I've just seen your post on lugnet and visited your Technic site - that is quite some achievement, it must have taken a lot of work to prepare all the images, information etc! It was a real nostalgia trip for me seeing these old models, I owned a fair proportion of them at the time, and I still have them, mingled in somewhere in my collection. Seeing them on your site makes me want to dig out the instructions and have a go at building them again.  I'm looking forward to seeing  future additions to your site.
Over the years, several new pieces were introduced in this line as well. The new pump was spring based, and could only be operated by hand, which limited pneumatic power to how fast it could be manually pumped. This obviously limited the power of pneumatic circuits. So in 1992, LEGO introduced two new pieces; a small pump and a small cylinder. The small pump did not have a spring on it, and it was designed to be operated by a motor, which would allow for continuously-running pneumatic creations. As of 2011, the small pump has only appeared in one set — 8868 Air Tech Claw Rig (1992) (found on Peeron) — and a few parts sets (no longer available). A new version of the small pump was released in Lego set 8110 Unimog U400 (2011). At 2L, this pump's stroke is 1/3 longer than the old one's 1.5L, 'L' being the LEGO unit of a stud. This made it much easier to use in studless construction.
Gears have been included within Lego Technic sets since 1977 as a way of transferring rotary power, and of gearing-up or down the speed. Gears come in several sizes: 8 tooth, 16 tooth, 24 tooth and 40 tooth spur gears; 12 tooth, 20 tooth and 36 tooth double bevel gears; and 12 tooth and 20 tooth single bevel gears. The double bevel gears are cut so they can also be meshed as spur gears. There is also a 16 tooth clutch gear, and a 24 tooth friction gear that slips when a certain amount of torque is put on it to prevent motors from damaging any parts or burning themselves out.
Likewise, adults who may have spent their working careers on a research vessel can spend weekends assembling models that closely resemble the ship where they work and gain a new appreciation for how it all comes together. By finding a Technic set that aligns with pre-existing goals, hobbies, and interests, the process of building them will become even more engaging.
Technic has certainly produced a lot of large models this year. Only 5 out of the 12 sets this year are under $50. These three are the best of them all, in my opinion. The accuracy of detail in the Volvo EW160E and the CLAAS XERION, combined with their functions, make them truly great sets. Now, the BWE is indeed the largest Technic set ever by piece (it’s 7th largest overall) and probably size, and it’s my favorite of the three. Its poor performance, however, lets the model down somewhat. I think it needs 2 XL-motors, not one, for power. The Mobile Aggregate Processor works okay, though, and it looks quite cool. Sadly I will have to pass on it, in favor of many other sets this year. 🙁
It’s usually hard to find a reason to criticise the packaging of LEGO sets, but here’s something I was very confused by. Nowadays, plastic bags with pieces come in 2 different designs — one with a white stripe in the middle (new design) and the other is without it (old design). I have nothing against bags of both designs mixed in one box, but you have to be extra careful with bags #6 and #9. While old bags had a distinctive dot after the number 9, bags of the newer design don’t have one. And this is how I got a picture like this:
The first dedicated Technic motor was a 4.5 volt rounded brick (p/n 6216m) released in 1977 as part of the Expert Builder Power Pack (960-1) and Supplementary Set (870-1), this output via a small protruding axle that would rotate when the motor was powered. The motor was not geared, resulting in high-RPM, low-torque output. Gearboxes and a square casing were available. A 12 volt motor of the same physical dimensions as the 4.5 volt motor was also available in set 880-1. The 12 volt version is visually distinguishable by being black, rather than grey.
I am a newbie to Lego and wanted a challenge. I did a couple of the small Architecture sets before tackling this. I know nothing about cars. But the directions were good enough that I managed to complete this with only a few missteps and episodes of frustration. The build was very absorbing and satisfying, and I am enjoying displaying the model on my desk at work and showing it to people.
These Lego building sets are great toys!! I ordered this one next day and it came fast and on time for my son's birthday. My ten year old loves to build these!! If you have a child who likes to build things this is the toy to get. My daughters also love these so great for boys and girls!! It is a smart toy that makes kids use their hands, follow directions and exercise perseverance. It will take him a few days to get this built and definitely worth the effort.
