The goods: 1. Loads of parts!! Just too many parts in the box and the weight almost breaks the yellow LEGO vinyl bag. If you ordered it from Internet, give some praise to your delivery people. 2. It's not just many parts. This set contains loads of square frame parts and gears which are super useful in any MOC designs. If you want to dive into Technic building, this set is a MUST buy set. 3. Many functions. Rolling conveyor belts and bucket wheel operation are already worthwhile to make a contraption. This set also moves forward and backwards and the superstructure rotates. Although the bucket wheel elevation and lower conveyor part rotation are manual but it's not too hard to motorize it due to its sheer size!! 4. Although you can't mount a Minifigure, this model is actually a one of few Minifigure sized Technic models. The cockpit can contain a Minifigure if you modify the seat with a proper studded one. (This is a definite plus for anyone wants to play with!!) 5. The finished A model is a huge contraption but is actually very sturdy. You can carry this heavy contraption by holding the top part of the arch!! The bucket wheel arm itself is really sturdy as well. You can even wield it around without problem. The drawbacks. 1. Too many parts and gears: causes too much backlash and almost impossible to debug when something isn't working well. I've changed the tandem clutch wheels with 24 teeth gears to ensure smooth bucket wheel operation (see one of my pictures.) But this isn't safe especially if any mineral(or Skittles!!) stuck into some corner to hamper any motorized operation. It's gonna break rest of gears or overheat PF XL motor. 2. The backlash is severe. For example. The lower conveyor belt lock is almost invalid. Even though you engage the lock, the conveyor belt slides like +30 to -30 degrees without any serious impedance. 3. In other words, this set is super hard to make it operate properly. Although putting parts together is not hard at all(since this model doesn't have any pneumatic hoses and threads), fitting all the parts to ensure smooth operation is a great challenge. The hints on instruction manual aren't enough. You are warned!! 4. B model instruction is only available on the Internet. Browsing through hundreds of PDF pages (especially without proper index codes!!) isn't convenient at all. 5. The control panel has many functions. But the operation is kinda limited. You cannot mix any rotation with linear movement. i.e. The bucket wheel cannot rotate when the excavator is moving forward. A MOC project to work on!! Although I've pointed out as many drawbacks as pros, it's not a bad model for the size. Heck, this is the largest PF motorized Technic model (excluding fan designed MOCs) so far. Remark: You better visit Bulk Barn to play with this model properly!! Skittles!! Skittles!! more Skittles!!

As a seasoned lego builder I have an understanding how to build these Technic sets. This set is really impressive but I doesn't function as it should. The forward/reverse driving is jerky. The rotary bucket assembly jams where the 1/4 ring gears join because the ring isn't rigid enough to maintain a tight circle. The pinion gears that the bucket assembly rides on don't sit parallel to each other causing uneven load on the ring gear. I sent pictures to lego and they are sending new ring gear parts but I doubt this will fix the problem. During the assembly I made sure that all the gears were turning freely with no resistance as required for this type of set. I verified that everything was assembled correctly 3 times and still couldn't get this to work. In the pictures you can see the gear tooth spacing at the connection points of the ring gear are too wide for smooth operation.

    This thing is HUGE!!

    By Spoonegg

    from Gold Coast

    Comments about LEGO Technic Bucket Wheel Excavator (42055):

    I tossed up between this and the overpriced Porsche (42056). Even after reading some of the reviews about how slow it is, it doesn't work etc. I still choose this bad boy for the sheer size and number of parts and value for money. over 3 nights (11 hours total) this monster was complete. Now I was thinking about the other reviews when it came time to fire this beast up. KAPOW!! It lives, the bucket wheel turns perfectly along with the conveyor belt and it rotates with no issues at all. Yes, it is slow when moving forward or backwards, but so what its HUGE! The finished A model is a beast but is very sturdy. You can carry this thing by holding the top part of the arch. A couple of other things to note: The lower conveyor belt lock slides like +30 to -30 degrees. The control panel has many functions. But the operation is limited. You cannot mix any rotation with linear movement. i.e. The bucket wheel cannot rotate when the excavator is moving forward. Don’t let a few reviews put you off (I didn’t). This monster is a must have for any Technic Fan.

    Comments about LEGO Technic Bucket Wheel Excavator (42055):

    I loved this build. Especially bag 6, which is a significant number of parts to create the main excavator arm. My only disappointment was getting to the end of the build- most take too little time, an evening at best, but this model kept going and going. I have enjoyed more technical models, such as more complicated gearboxes, but the sheer size of this set more than made up for it. It was worth reading reviews where people have complained about the model not working. I took extra care with all power train components to ensure smooth, non binding operation and the model works perfectly. I'm not sure if the movement completely to scale, I almost expected it to move slower, but still it gives the real feeling of the colossal machine. It is a rare model when I am sorely tempted to get a second for the B model!

    Massive Build!

    By FourBarrel722

    from Lafayette

    Comments about LEGO Technic Bucket Wheel Excavator (42055):

    This set is both the largest in size and in piece count to any set in my current collection. I read the reviews and was a little deterred by all the comments about the motor being too weak but I decided to purchase anyway and see for myself. I'm glad I did! You have to understand one thing about this build - Don't RUSH! The trick to making everything work when you turn the power on is to make sure that once everything is together, and even during the build, that all parts are free moving and don't display a 'bind'; especially around the shovel area(s) and conveyor belt. If you can do that and put it together properly this set is sure to impress!

    Comments about LEGO Technic Bucket Wheel Excavator (42055):

    I bought this model as therapy as I have vascular dementia. I found the instructions fairly easy to follow. Shame that the instructions for the alternative build are only on line, as I found them less easy to follow for some reason, and have not started the alternative model yet.

    Got this set for Christmas and would defiantly recommend it. Very clever how it all work. I have many sets I have collected over the years and this is my favourite. Only way it could be better if it moved a bit quicker but apart from that I love it

    Comments about LEGO Technic Bucket Wheel Excavator (42055):

    Great model, lots of details and love the movements. Sadly the bucketwheel has very little power from the included motor so it can't pick up things easily and it can jam with peices stuck on the belt. Awesome and engaging build and the result looks very impressive. Even the little truck included is cool.
