Extra large wheel chock

[uscarry45]

Several times I have needed to keep a very large tractor from rolling while working on it. I am able to find wheel chocks for semi trucks but nothing larger. I would like to find or build a extra large wheel chock. I have used blocks in the past but they are very heavy and not easily transported to the field. Anyone built anything or aware of one’s I could buy? The tires I am looking to chock are about 50” in diameter

Real good on size - looks expensive for what it is but may have to buck up and buy

You could make the outer trapezoid frame from 2x12 and glue and screw ¾ or 1 in plywood for the sides to that. Paint green, red, or orange.

for 250 a piece I would make some out of a piece of firewood instead lol

I think if I was going to make one I'd use aluminum to cut the weight.

I’ve got the drawings for chocks for up to KC-135 size aircraft at the house. Will post it when I get home in the morning.

You can search for chocks for off-highway haul trucks, but I don't think you will like the price-

I think I would be ok with a light weight here, and I would(and always am) a little skeptical with the very light chocks.

Some wood and of you want them to last forever coat them in some epoxy/fiberglass resin

... I have used blocks in the past but they are very heavy ...

What are you considering up be very heavy? I've made wheel chocks from a few layers of 2x cut to the right shape. I've welded up triangular "space frames" in whatever size was needed. I've also stood plywood triangles on edge layered up to give the width I wanted. The lightest was the steel. The coolest was the plywood. The simplest was the 2x. All were pretty easy to build.

What I have been using are pieces cut off large beams 10x10“ and 12x12” probably 16” long. They are big enough where it takes two hands to move and I am sure they are 20-30lbs each. I am sure if I made them angled it would cut the weight in half.
really appreciate all the replies. I think it’s ridiculous to pay 400.00 for something I can make and work equally as well

I shoved a brake rotor in front of a rear tires on a juice brake brinks truck I dropped st the dealership cause they couldn’t come up with any chocks. It seemed to work atleast till I left the parking lot!

I've usually used a log, but we had a ton to pick from with logging equipment repairs.

"Large airplane chocks" are what came to mind, and whaddya know, cvairwerks had drawings!

For a tractor, I'd build something similar out of the largest hunks of wood I could find, stacked and lagged together if you're using lumber, or chainsawed out of logs. Since access to the back of the wheel is more difficult with a tractor, the rope tying them together in the back would have to be left out.

If you'll be using them on soft surfaces much, maybe screw cleats to the bottom?

Also, if things are getting ridiculously heavy, maybe a wheel at one end, placed off the ground such that when you pick up the other end you can roll it around like a wheelbarrow.

Back when I helped out on the farm, we usually used assorted logs. A log with a handy stub of a large branch sticking out so it wouldn't roll was especially prized.

We also had large hunks of lumber lying around for cribbing and chocking. It's a good use for stuff too rough to use for construction.

Need to make a few different sized sets for various aircraft I'm around. Just happened, that a friend had the drawing in some of his research stuff.
