Technic Rough Terrain Crane 42082 Building Kit (4,057 Pieces)

Awesome LEGO project. This was my first Technics build. I’ve had LEGOs when I was a kid, but never anything like this. The instructions are well done. Full page just for 1 step in some cases. With all that extra page space, they could have made the blue area with the parts breakdown a little larger. Sometimes it’s hard to see the difference between 2 tiny black pieces or even grey ones that look a little bit black in the picture. I knew this had a lot of tiny pieces, so put a border around my table using 3/16 weather strip tape. Then used double sided tape on the surface of the table for knolling the pieces, which really was the best part of the build. I spent about an hour or so each night working and taking my time, double checking and sometimes triple checking each step, but unfortunately somewhere along the way, I missed something. The crane doesn’t rotate under its own power. Switching the turntable switch to clockwise or counterclockwise doesn’t engage the rotating mechanism. If u manually turn the gears on the bottom of the crane with the switch engaged it does turn all the gears back to the motor. Set the switch to neutral and the gears disengage from the motor and give less resistance. So somewhere around step 105, you should verify that flipping one of the 2 levers on the bottom assembly should engage the top black gear and turntable. Mine didn’t do anything, I just assumed that a later step would engage the 360 degree rotation, rather than just spinning freely. Maybe they could add some verbage to the instruction manual to check for proper assembly and movement at certain steps, since the whole manual is just pictures. I’m not sure if there is an easy way to fix this without taking the whole thing apart, back to step one, which is the assembly of the crane rotation. Oh well, still a fun build. Kept me entertained for several weeks. I highly recommend building one if you have the means, it is a little pricey for something to just sit on the shelf. It would have been nice to see this as remote control and drive it around the house. I would have enjoyed that more, but I knew that it wasn’t before I started.

This being a Lego Techic, I was expecting it to be operable from the Lego app on my smart phone. Not so. All the functions do work, but you have to manually select them by shifting different levers on the transmission, which is a marvel in itself. So many gears and shafts make for a very complicated build. Driving and steering are hand powered only. It does make for an impressive display piece.

I bought this for myself, an...older...person, as my first Technic set. I am about 2/3 of the way through it and it does not disappoint. A few hours each weekend with a cup of coffee during the a morning session and an adult beverage during the evening session. What a great kit. Even better than old models I made as a kid, but with more movable parts and no dizzying glue to stink up the house. Take your time. Study every page and compare it to what you have before moving on. The diagrams are amazingly accurate and I have caught myself in an error a couple of times (usually during the evening sessions :) ) before moving on. Pay SPECIAL attention to the pages that do not show how to place new pieces; they show something that needs adjustment before moving on, often adjusting things that you added hours or days ago and probably forgot about. Bottom line: If this is your thing, buy it. I've bought a few Technic and Expert Lego kits as a result.

It was a good challenge for my 11 year old who is pretty good with legos. We are having trouble getting the crane to go up and down vertically. I don’t see an issue with the gears but will need to take apart and check it out. There are a lot of moving parts which he did like. It was fun and very well made. Still feel it’s pricey but worth watching it being assembled.

This is a great lego set. It was fun to assemble, but had a few frustrating parts. What you get: The box it comes in is very large - roughly 3 feet wide, 2 feet high by maybe 8 inches deep. When I got it, the normal seals on the box were undone so I was worried someone might have gotten into it or gotten one of those 'renewed' (i.e. returned) items. When I opened the box I was a little confused. There were packages with numbers on them, some with multiple bags per number. However they started at #6. There was also a big white box that was inside as well, that I found the remaining bags of legos along with a sticker sheet and 2 manuals each about a half inch thick. Both for the main crane design, not the mobile pile driver you can also build. In all the numbers on the bags were 1 - 13, and each number had between 1 to 4 bags with the same number. In a lot of the main bags, inside had smaller bags of legos. I got the 'standard' packaging, which like normal Amazon packaging where the regular lego box comes inside a brown cardboard box. I don't know what the overbox might be, but I figured it's not worth the $7 or so extra. Here is my prospective, as an adult building this set. I had a folding table I built it on, it will take a while to build so you don't want to build in a place you have to share or put it away all the time. I worked on one number set at a time. For each bag, including the smaller bags in the bigger bags, I put the contents into their own plastic bowl. I think I had up to 6 bowls at the most at one time. Often each bag would have it's own kind of legos so keeping them separate helps finding the pieces you need. Each set took between 30 mins to 2 hours to complete. It took me about 17 hours to fully assemble. For the most part the instructions were decent. There are no words, just pictures. The crane comes with a motor in the top section that using a series of levers, powers 5 functions. In the top section: raise and lower the hook (which is really just a block with nubs to loop chains on), extend (in and out) the boom, and raise and lower the boom. In the bottom section: rotate the top section, raise / lower the stabilizers. You can't really test things to see if you got the power functions right until towards the end. After I got it complete I found the top section rotation didn't work. It took me about 4 additional hours to figure out what was wrong (a missed axle connecting piece in the gearbox which is built at the very start) and to fix it. It is extremely difficult to get into the insides where the gears are, I had to do a combination of disassembly and bending that it wasn't meant to do. The instructions also don't indicate in any what what gears and pieces do; the area I needed to fix didn't have good visuals in the instructions, so it's very hard to troubleshoot. Also as you put the ends of the set on with the stabilizers, the instructions don't tell you that you need to have them all aligned, even front and back as all 4 are controlled by one switch. Once again, this set is not made to easily take apart to fix something. All assembled, it is pretty big. From the top of the extended boom to the ground is 40 inches. When fully lowered, the boom still has a little upward angle. The battery pack takes 6 AA batteries.

Caveat: I am half-way through the process of building this (spending ~1 hour per week for 1.5 months). I highly recommend this set for the enjoyable build process, the educational aspects of seeing and manipulating the mechanisms, and the quality of the parts. Nearly every time I sit down to work on it, I find something else that pleasantly surprises me, whether with how different components combine so smoothly, or with how helpful it can be to build and play with a mechanism to understand how it works. I have had no missing parts so far, and every part has been well made, fitting together like it should. I have tried to work on the set with my 5 and 7 year old children, but they tend to get bored quickly, so this set is probably better suited to older children or adults.

Es el segundo lego technic que armo y esta brutal, las imágenes en internet no le hacen justicia, es más grande de lo que aparenta, la construcción es muy divertida (toma alrededor de 15hrs armarlo) y una vez terminado las funciones que tiene son muy buenas, muy recomendado

Super entretenido. Uno de los mejores modelos Lego

I highly recommend this crane. At over 4K pieces, this is a great value compared to both higher and lower priced sets. You get a lot in this package. The finished crane looks fantastic. I purchased this for my 8 year old son. He’s built a number of technic sets in the past (rally car, mobile crane). He was ready to step up to a more advanced set. He worked on it for 4 days with minimal supervision. A few minor errors were easily fixed. Just make sure you double check every few steps. Everything works! It is a fun building experience and you feel a sense of accomplishment when it’s complete. This thing is big!

Great Lego set. Lots of detail pieces (There’s even a storage tray for the dolly pads) and looks great in my collection. I have the Powered Volvo loader and the older powered excavator and this was far easier to align the gears and motor so that it operates smoothly. Very fun to build
