Frequently Asked Questions / What kind of loads will your finished cattle guard support?

We engineer our Cattle Guards backed with P.E. certification. Each is sealed with an HS-20 load rating or 32,000 pounds per axle. To put that in perspective a loaded 120 HP John Deere weighs about 12,000 pounds. Which is only 6 to 7,000 pounds over the rear axle.

Can it support a loaded semi?

Whatever the DOT allows on the highways these cattle guards can handle. The DOT limits the weight of a standard 5-axle tractor trailer on interstate highways to 80,000 lbs. (20,000 lbs over a single axle, 34,000 over dual axles). An ‘economical’ cattle guard would collapse under these stresses. Which is why we only offer HS-20 rated cattle guards.
