Project M- Backhoe

[ZCerberus]

First up for round 2 is the backhoe.

Like almost all construction equipment, I have noticed a very wide range of sizes of the machines. That being said, the basic design elements (like functions and locations of engines and gearboxes etc.) and relative proportions tend to remain the same.

I went with the “tractor” style shaping here with the larger back wheels, smaller front wheels and slender front engine section.

Since size is less important than proportion and function, my design decisions were based on one major factor- the bucket sizes for the front loader portion that I had available. I had a 6-wide bucket and an 8-wide bucket available. I decided to use the 6-wide and kept the 8-wide standard bucket thinking I would use the 8-wide for a proper front loader, though I ended up using a completely different bucket for the front loader. There also wasn’t a great current scoop bucket for the back arm available in the proportions I was using. The best option appeared to be the older finger hinge buckets I had from various catapults collected during my classic castle days. The scoop (and probably the entire backhoe) is perhaps a little undersized, but I think it looks pretty good overall. Since I already had an excavator, I also decided to add a little jackhammer attachment for the backhoe so it could have an additional function.

One thing I am especially pleased with is the outriggers- the design of which I carried over to another build. The big issue with the outriggers was, of course, to make them sit at an angle relative to where they connect to the machine. A Technic “triaxle” with some lift arms did the trick and as I said, I rather like the result.

Overall, I am satisfied with the shape, though I think if I ever revisit this build, I will go with the 8-wide bucket and bulk up the backhoe a bit. One aspect of the backhoe that I really appreciate is that it is fairly rugged and can withstand some punishment from my now almost 3 year old son Miles with only the bucket tending to fall off.

Nice! Very elegant!

Excellent backhoe, the outrigger design is quite clever I like the scoop piece used for the rear bucket, and the slightly tilted windshield

Well-ell! This look fantastic! I like the pneumatic stabilization legs. Good detail and great overall shape. Recognizable instantly!
