## Description

Enjoy building and operating this massive 2-in-1 Bucket Wheel Excavator construction toy, the largest LEGO Technic set to date! This awesome, meticulously detailed reproduction of a real-life mining excavator comes with a cool dark-blue and yellow color scheme and an array of authentic features and functions, including hand-railed walkways, huge tracks and a detailed cab. Switch on the included Power Functions motor and you can activate the conveyor belts, rotate the massive superstructure and maneuver the colossal machine into position. Then activate the boom to lower the gigantic, digging bucket wheel and convey the mined material to the waiting mine truck. When you feel like another building challenge, rebuild it into a Mobile Aggregate Processing Plant.

Review: A must have for Hardcore Fans - I saw this featured on YouTube before Christmas and couldn't wait to get it. After all this time checking the Tru stores I figured I was going to have to buy it online. Of course, no issues with desertcart, but paid $25 for 2 day shipping, and the carrier dropped the ball, got it in 3 days. The box is absolutely massive. Cut the seals and dump out alot of bags, and then a box. Inside the box, more bags!! Almost 3000 parts compose this model. Bags are numbered 1-8, corresponding to the phase of build. Phase 1 builds the dump truck, and contains the material for play. Phase 2 builds the frame. Phase 3 builds the tracks. Phase 4 builds the machine frame. Phase 5 builds the exit conveyor. Phase 6 builds the digger wheel. Phase 7 builds the rear of the digger and the power functions. Phase 8 builds the accessories. Built the model over 4 days. Being almost 3000 parts, I thought it would be a grueling build, but it wasn't the case. I recently built the Arocs truck, which was tedious. I just wanted to get it built. The Wheel Excavator was fast and enjoyable. I checked things as I went, seeing there are a lot of axles and gears in this set. With the motor being at the rear end of the digger frame, getting to the tracks takes a lot of mechanics. Finishing the build, I have to say it is quite impressive. However, I have to say using 1 motor for all the functions kind of was a let down. I built the Volvo loader, and it has 4 motors. There are really only 3 functions powered: tracks, wheel/conveyors, and turning the machine. Turning the machine requires the conveyors and wheel running. You can't run the tracks with anything else engaged. Raising/lowering the digger wheel is manually operated, as is rotating the discharge conveyor, which has a locking mechanism, which, from gear backlash is kinda, pointless. I realize most of this was engineered to mimick the real machine, but, being a Flagship model, I think things like the railings, the goofy rear access ladder, and the multiple gear boxes could have been reduced to add a couple more motors and some better functuality. IR remote capability like the Volvo loader would have sent this over the top. I suppose being Lego it could be reworked to add these in, but I really don't want to take apart the models I have to get the parts to do this. So, although it is completely awesome, huge, and definitely a must have for the serious Technic builder, I just feel a few small things could have made this the biggest, baddest set ever made, period.
Review: Love lego - There are some very hard part when disassembling after you played. Otherwise it is a very good Lego set, no missing pieces. Looks great! Some function does not work as expected due to the complex gearing mechanism and construction solutions.

## Questions & Answers

**Q: does it come with motors**
A: It comes with a single XL motor and the battery box to power it. It takes 6 AA batteries. The motor is in the back end of the bucket wheel's arm. Three red switches, each with a neutral and up/down position route the gearing to power to each of the functions the Bucket Wheel Excavator can perform. The single motor, depending on switches and their direction, can make the model roll very slowly forwards or backwards, slowly rotate the  arm structure 360 degrees in either clockwise or counterclockwise (while the bucket wheel and conveyor are turning), or just turn the bucket wheel and conveyors with no other function operating. The tilt of the bucket wheel is manually adjusted with a gear using two linear actuators. The lower conveyor has a gear to move it roughly 180 degrees horizontally, but has a switch to somewhat loosely lock it's position over the dump truck.

**Q: Are there instructions for the secondary model? We only received the one (3/4" thick) main booklet.**
A: Hello. As you have heard the B-Models for most LEGO Technic sets are not included with the set and are available only online. This is done for a few reasons but the most important reason is cost for the consumer. We came to a cross road many years ago and found a way to make our sets cheaper for every consumer. If we had our B-Model instructions online we could make each of our Technic sets $5-20 cheaper. Considering many consumers do not even build the B-Model this was a huge savings without actually taking anything away from the set. The LEGO Technic team has created a great app that they upload many of the B-Model instructions on called LEGO Building Instructions. Here is a quick link to the LEGO service site where all instructions are stored for all sets even B-Models: https://www.lego.com/en-us/service/buildinginstructions/search#?search&text=42055%2520Bucket%2520Wheel%2520Excavator%2520Technic

**Q: Size of package?**
A: The size is 29" x 19" x 7" All figures are in inches.

**Q: Is it rc**
A: No it is not RC.  The functions are controlled through the motor and a series of selector switches at the end opposite the buckets.

### ⭐⭐⭐⭐⭐ Seriously fun build
*by R***N on July 4, 2018*

This was a great build, even based againsy other big lego sets. There is so much detail in this set it was great. It took me about 2 weeks to put this whole set together, but I was not rushing it and was doing a little at night after work. The engineering behind this piece was also amazing, from how it turns to how the bucket scoops work. I 100% recommend this for oldrr amd more advanced builders.
