Input on bringing my dude Big Daddy Crawler (a tracked vehicle) next year

Post by AddamsonFlint » Wed Aug 01, 2018 8:41 am

Ok, first off, sad but necessary disclaimer, in the internet-age of saying whatever you feel like because of the lack of consequences:

This post is for positive input and suggestions. If you wanna sip haterade and talk smack, take that shit over to the Open Discussion page, or better yet, get the F- off of ePlaya.

I have a crawler/loader/backhoe endearingly named Big Daddy Crawler. Specifically, it's a 1976 JD 350-C, for any gearheads that care. I am thinking of turning it into a mutant vehicle next year.

DMV does allow tracked vehicles. My only concern is my grousers (the pads on the tracks), as they are slightly cleated. They aren't crazy like a dozer, and actually are specifically what one would normally want to have in a sandy environment. But obviously it's not just a sandy environment, it's the playa; and that is understandably different.

Some mutant vehicles get licensed solely as on-playa, and are not permitted on city streets. Maybe that's what he would get restricted to. Worst-case scenario, I'd have to rubber-wrap my treads. Doable, but a total pain in the ass, not to mention "not cheap."

But I thought I'd put up a post here to field any spiffy perspectives from others.

Thanks for reading,

Flint

Hey!

I suggest that you spend some quality time with the DPW folks at the big rig yard (5:30/Esp/Rod's) this year to get ALL of the dusty info (don't drool on the equipment, they hate that).

My time with MV builders leads me to believe that tracked vehicles are discouraged out there, but exceptions could be made.

I've seen a couple of tracked vehicles out there. not as heavy as yours, but tracked, none the less.
I'd imagine the big deal for DMV would be how you "mutate" it, in that it has to not look like the "original". Some exceptions have been made for very large capacity (in humans) vehicles, sort of "party barges", but even that is rare. Low as your cleats are, they'll pulverize the crust (if there is any), anywhere you go. Keeping with a slow speed, I'd not see a ton of extra dust, though it will make a lot at times.
Another concern, is leaks. I've seen few tractors, especially if "older", that don't leak. And, leaks are not ok, and there are folks out there who check, in camp and such. If you have any leaks, regardless of how small, the minimum you should consider is parking on some sort of tarp or pan.....which, given you vehicle, would be interesting, I'd imagine.
I'd love to follow you around, just to watch, point, and laugh, and the undoubtedly varied reactions you'd get, from pure hatred, to glee. Something like that would elicit so extreme responses, I'd imagine.

I also note how cute it is, that you want to tell others how to respond on or to your thread.....

good luck.

It’s not a sandy environment at all.
It’s dirt with a fragile upper crust, that your tracked rig isn’t exactly going to be easy on.
That’s the elephant in the room... that and your attitude of already knowing so much about something you know very little about.

Playa sand content defined as mineral particles greater in size than 65 micron

3%

No sand.

Clay. Dry, slick clay powder. 200 square miles of it.

Some silt too but mostly clay.

Definitely go to the BM DMV guidelines ASAP.

Tracked vehicles are non-trivial on their end.

The only tracked vehicle I can recall seeing in the past several years is this. Much different treads than yours and substantially mutated.

The contact force of a tracked vehicle with the soil is very small. Estimating for that vehicle less than 3psi. That's less than a shoe and much less than a bike or a tire vehicle. You might explain that to DMV - it's counter intuitive.

But that’s not the only thing.
The issue is turning, and how smooth or cleated the tracks are. In a straight line things are pretty peachy.

If you watch a really good excavator operator spin his machine on a surface he doesn’t want to tear up, he pushes the bucket down on the ground to lift the machine up on just the back edges of the tracks, then counter rotates them while spinning the turret to stay with it.

Just counter-rotating the tracks down flat on the ground causes a lot of scrub.

I think If the driver is good and operates carefully it would probably work out. It’s all about the operator.

As a rule, what is the price of such a device?

Honestly dude, your rig is sweet but it's probably not the right candidate for a tracked MV.

Think a shit ton of energy to get it out there, lotsa space on a trailer that could be better utilized by couches, and totally completely unnecessary to bring your own heavy equipment to Burning Man. If you really need equipment for digging trenches or holes, it can be arranged or bribed from HEAT (heavy equip and tools). As far as using the bucket as a lift? bring a ladder. Also, trying to simultaneously use a loader/back hoe for setup and covering it with enough mutation to get it licensed sounds like hell.


And if the goal was to just have a tracked MV cause treads are cool and post apocalyptic, I'd go with something that a) had flat rubber tracks to mitigate the issues mentioned above and something that could be built upon, like a flat carrier or an excavator stripped down to the swivel.

Ouch, that is some serious harsh from a pile of fucking bones. ;)

The magic is in the articulating implements on the bow and stern.

Think this as inspiration. Different device the crane and all but you gets the idea. there is potential there for the right kind of twisted engineering.

The DMV has people who know a lot about heavy equipment.

really? how does one judge energy usage at this event, by anyone? Or how they want to "Burn"?

Jeez you guys. He asked for input, I’m only trying to help.





But yeah, better listen to the old farts and disregard my discouraging words :roll: :wink:
