    Mother of all Lego mobile cranes

    By itsavette

    from Toronto

    Comments about LEGO Technic Mobile Crane MK II (42009):

    What is big and yellow, highly complex, and will likely triumph over every Lego set you have in your room as a giant monolith? It's not a trick question; it's the latest 42009 Mobile Crane Mark II from Lego Technic. The Walkaround To recent date, there have been two other Lego Technic mobile cranes: #8053 in 2010, and #8421 in 2005. Arguably only 8421 (or Mark I) was truly worthy of greatness; in fact, it kickstarted a whole new generation of construction vehicle builders. In comparison however, 42009 (a.k.a MK II) completely overshadows its predecessors, both in size and overall complexity; first hint you get is when you pick up the box; packing 2,606 pieces. So yes, it's heavy. The Building Experience There are 6 (six) instruction booklets: 3 for the truck itself, 2 for the superstructure, and 1 for the crane arm. Lego has also purposely divided up all part bags per each section of the set, so making sense of 2,606 parts is a lot easier. The instructions are clear and extremely precise all the way; this is a good thing when you're dealing with a project this big, this complex and involving thousands of pieces. One thing though - and I cannot stress this enough - is pay very close attention when fitting all the modules together, particularly all the bits involving gears and axles. This is crucial to the model functioning properly in the end; in my case, I bolted two components together backwards, so the outrigger system failed to deploy. Luckily, I noticed this in time and switched the components into the correct place. As I learned, be sure to check every major assembly twice before moving onto the next page and you'll be just fine. In terms of building it though, it was one of the toughest and the most rewarding Lego Technic experience ever; and this is coming from someone who's been building Lego Technic for almost 15 years. Scale and Features Without any exaggeration, the MK II Mobile Crane is massive. Crank up the crane and extend the outriggers, and it becomes even bigger. Details are all in the right places too; opening doors on the truck and crane cabin, V8 engine, and tons of cool stickers. This is easily one of the biggest Lego Technic sets I've ever seen. The MK II's functionality is mouthwatering; 8-wheel steering system, working V8 engine with differential, deployable outriggers/arms and of course, full crane functionality with 360-degree capability. And here's the kicker: all the MK II's power functions are achieved by just one motor; which is why there are multiple gearbox controls on the crane and two on the truck to be able to manually operate all the functions. Adding more motors would of removed much of the very brilliant and well-engineered gearboxes, but it would of consequently driven up the cost of the set as well. Never thought I'd say this, but I actually prefer the gearboxes in this case; makes you feel like you're in that cabin maneuvering the controls. You'd also be surprised how much weight the crane can lift until the motor starts to struggle. That said, you can get yourself Lego's Power Functions XL-Motor, L-Motor, IR Receiver and remote control, and you can start adding more motorization to your crane, should you desire more. Conclusion As a technical challenge to your inner engineer, as a test to your skill and patience as a Lego builder, the 42009 MK II Mobile Crane is a fantastic example of what the Design Team over at Lego's Technic division can achieve when they really put their minds to it. But it's more than that. It's a brilliant toy with lots of guaranteed hours of play time for any child or adult (or childish adult) to build and enjoy over and over again.

    Big, complicated, impressive, fun

    By Kunom

    from Undisclosed

    Comments about LEGO Technic Mobile Crane MK II (42009):

    This is a really huge build, as others have said. And it makes a large, robust, impressive looking crane. A few observations: - the main build is actually pretty dense, with all the cogs and mechanisms - the crane motor unit is the most complicated on both builds, but particularly so on the main crane - so many cogs in such a small space! - the alternate build is less dense, but obviously has three parts to it, making it more fun play wise - the main crane arm can take some weight, but it is obviously not meant for heavy lifting, especially with the arm full extended. - there is a huge amount to learn, with both models, in terms of techniques, mechanisms, etc. One thing I really liked is that each model takes a different approach to the use of the crane arm and the main mechanisms are very different in both. - the complexity though was beyond me, and though I could appreciate it, my brain isn't big enough to be able to apply much that is here. I am sure others can though - these are cranes, so not meant for speeding around, but the secondary vehicle on the second build was the most fun to drive around - the most impressive thing to me on the main build was the extending legs, followed by the use of string to control the extension of the crane arm - the most impressive thing on the second build was the way the crane arm's gripper grabbed hold of the container.

    Waited forever

    By GazzaSinkers

    from Sydney

    Comments about LEGO Technic Mobile Crane MK II (42009):

    I have never waited in anticipation so much of getting a Lego set since I was a kid in the 70's and getting sets 855 (crane) and 853 (Big Car). When I received the box the first thing to note is the sheer scale that awaits you...and then it gets better. Make sure you allow about 18-24 hours build time for this one! After sorting the bags (great idea) and opening No.1 you realize this is not going to be a walk in the park, like sets of old. The size of the truck base and the turning it around, and over, makes it fun seeing how the things will work from different angles. The No. 2 section is by far the most tricky if you haven't had a set with the switching system of levers before, I had and knew what I was doing, but newer Lego users may need a bit of help here. No. 3, the boom...great to see a 2 stage boom which moves so smoothly. I was very impressed. Overall I think this is the most impressive models in Lego Technic history. It sits well with my 9396 Helicopter and is a must for any serious Lego builder

      Well worth the money

      By Annihilator001

      from Grovetown

      Comments about LEGO Technic Mobile Crane MK II (42009):

      I found the build to be average for difficulty. Sure there were areas some what challenging but for the most part pretty straight forward. The model is pretty impressive. The whole model seem to be nothing but a big transfer case of gears. The whole time you are building the model it seems you are putting together gears. But with that said the functions that it can do from only one motor is pretty impressive :) The over all build was one of the better models I put together. I like the fact the stabilizer arms actually bare the weight of the vehicle when fully deployed. I never ran into problems with the gears having to large of gaps everything seems to be just right and the clutches in the system work. I think one motor in plenty for the crane. What would be cool though is if there was a remote control for the driving of the truck since the steering already well geared with all the turn wheels and it already geared for 2 drive wheels.

      First Technic Set-FUN Build

      By korFINN

      from Undisclosed

      Comments about LEGO Technic Mobile Crane MK II (42009):

      This was my first Technic purchase, and it was a good one. I had been hesitating getting into Technic, and can't say I am that I am in yet. However, Mobile Crane MKII just could not be passed up. It was quite challenging, but very fun to build. There were a couple of things I did wrong, but was able to figure them out, without too much dis-assembly. Would highly recommend this build to anyone.

      This Is The Best LEGO Technic Set Ever!!!!!!!!

      By Sailorcam297

      from Undisclosed

      Comments about LEGO Technic Mobile Crane MK II (42009):

      This the best lego set I have ever built and used. When I first heard that this was going to be a challenging build I didn't believe that it provide such a challenge. I think that would have made this set even better is if the crane's steering, driving and the physical crane were remote controlled.

      Biggest yet

      By Bigkid1002

      from Peterborough

      Comments about LEGO Technic Mobile Crane MK II (42009):

      This model is huge when complete, anyone thinking it can't be worth the price is very wrong. You have to take care with the instructions as there is plenty of scope for errors. The power functions are generally impressive, the only slight disappointment is the speed when lowering the outriggers, this takes quite a while. Sometimes the model seems to struggle with the outriggers, this may be as a result of the length of the rods used to transfer power. Given the size of this kit maybe it could have done with two motors, although I appreciate this would have increased the cost further. Overall this is a great Technic set and a massive improvement over previous crane models. I'd be happy to recommend this crane to anyone and for the size and functionality I think it represents good value for money.

      Fantastic product - best Lego I've ever had!

      By fishsponge

      from Undisclosed

      Comments about LEGO Technic Mobile Crane MK II (42009):

      This product was fantastic - I haven't played with Lego for years, then browsed the Lego web site and saw this and SO wanted it, so I was then given it for Christmas! It took me about 2 days to build it (16-18 hours in total), but that's because I was also doing a time-lapse photography of me building it, so if you search YouTube for "fishsponge lego" you'll find my two time-lapse videos of me building this fantastic crane! Thank you Lego for creating this!!
