How Canadians Build Dump trailers different.

What happens here

Shane highlights the innovative 'engineered sill design' and tubular frame of the Southland Trailer, distinguishing it from conventional cross-member designs. He explains that this design, similar to full-size dump trucks and end-dumps, significantly improves strength and reduces overall weight, allowing for a higher net payload. The trailer's Gross Vehicle Weight Rating (GVWR) is stated as 15,400 pounds, with an empty weight of 3,120 pounds, resulting in over 12,000 pounds of net payload. The presenter confirms the real-world durability based on his extensive use of Southland Trailers compared to other brands.

Goal: Explain the structural advantages of the Southland Trailer.

What they say

Hide

>> Yeah. So, they're super high on engineering. And Stan, you probably saw that when you went through their factory. They're going to start up front with a tube frame, but then what's really unique is this engineered sill design. They've got engineered beams or structure running the long way. And that is different than what you'll see on most trailers. Most are just going to have a subframe underneath the box and then crossmembers running the crossways on the box or like I said, these are going to have the engineered cell beams running the long ways on the trailer and then your hoist is connected directly to that. So like you saw when you're up in Canada, very similar to how they were done on a dump truck. Okay? Standard dump truck is exactly the same way as this. Not crossmembers on the floor. >> Well, they build on. So they they manufacture those for those. And personal experience, I own a number of dump trailers. I mean, I own actually a ton of them. And when I look at one of my other trailers, which has the cross beam design, and my Southland trailer, which I have two main dump trailers that we run pretty hardcore over all the other ones, Timmy, we have the two trailers we normally run for everything, right? >> Yep. >> Yeah. And Southland is one that we grab and go all the time, and then there's another one that we grab and go all the time. And when I look at the floor of the Southland trailer in comparison to the other trailer, there's a night and day difference. The other trailer that has the crossmembers underneath it, that trailer looks like a washboard. >> In between those crossmembers, the floor is going like that and it's dinged and dented. And what happens is now our loads when we have wet, loose, sloppy material, we go up to dump it. We're now getting that load stuck. So, not only is this floor design different because you don't see dump trucks have that crossmember design, dump trucks have this design. Our our freight liner has this design. End dumps have this design. This is the This is the design that truck companies use and it does two things. It strengthens the truck bed, but it also lightens the load. >> Yes. Yeah. Yeah. So, this trailer has a a GVWR of 15,400 lb and an empty weight of 3120 lb. So, that's giving you over 12,000 lb of net payload. And that's super important, right? That's what you're getting paid to haul is the payload, not just the empty weight of the trailer. >> It has one of…
