The Physics of Trailer Loading Ramps

We take trailer loading ramps for granted. In other words, we just assume that a good set of ramps is going to do the job without issue. We usually don’t give any thought to how they actually work, or how they make our lives easier for that matter. If we did, we would be delving into all sorts of things related to physics.

As human beings, we are capable of using tools to do all sorts of work. Trailer loading ramps are just one example. When you understand the physics behind how these ramps work, you come to appreciate how much they enable us to do. There are plenty of loads truckers could not carry if it were not for the work done by loading ramps.

The trailer loading ramps we sell are intended for both straight flatbed trailers and those with multiple deck levels. They affix to the back of the trailer using clips to hold them in place. On the other end, wedges make the transition from ground to ramp a smooth one, allowing operators to easily drive or push cargo up onto the trailer.

The Key: Force and Distance

We will not get into all the physics of using trailer loading ramps, but we do want to cover some of the basics. The first thing to talk about is how ramps make it possible to load extremely heavy cargo on the back of a flatbed. Imagine a trailer carrying a heavy piece of construction equipment.

Without loading ramps, that piece of equipment would have to be lifted onto the trailer using a crane. Why? Because it takes a tremendous amount of force to overcome gravity when lifting an object by pulling it from above. All that dead weight requires a heavy-duty crane to get it off the ground. Furthermore, greater downward force is exerted on the object the higher it goes.

Using loading ramps still require some amount of force to get the piece of equipment onto the trailer. But rather than pulling it straight up, the operator is moving the equipment across an inclined distance. Spreading gravitational force across a surface plane at distance allows the operator to more easily overcome that force at any given point during travel. The result is less energy required to move the same object.

Other Physical Forces at Play

While the force and distance equation is the key equation for trailer loading ramps, there are other physical forces in play. For starters, you have both the potential and kinetic energy stored in the piece of equipment being loaded. That energy affects how the cargo is moved.

Kinetic energy is energy in motion. It puts increased stress on the ramps the further up the piece of equipment goes. Combined with gravitational energy, kinetic energy also puts stress on the rear of the trailer. That’s why ramps have to be firmly affixed and trailers have to be locked in position.

Potential energy is stored energy. It exists in the piece of equipment even as it is moving up the ramps. If one of the two ramps are unsteady, that potential energy could be transformed into kinetic energy, causing the piece of equipment to tip and fall off the ramp.

Rest assured that engineers work out all the physics before attempting to load a piece of heavy equipment onto a trailer. Operators know the size of the ramps they should use, how to anchor the ramps in place, and how to actually move equipment up those ramps. If it weren’t for physics, none of it would be possible.


What Does a Good Trailer Loading Ramp Kit Look Like?

Trailer loading ramps are yet another tool that flatbed truck drivers use to get cargo in place. But loading ramps for tractor-trailers are far different from the DIY ramps you might use on a small home utility trailer. They are much larger, much longer, and a lot stronger.

Mytee Products sells trailer loading ramps along with all the accessories truck drivers need to utilize them. If you are new to flatbed trucking, you might need an entire kit to start from scratch. Please note that our kits come with absolutely everything you need for loading ramp deployment. Other kits may not be as extensive as ours.

So what does a good trailer loading ramp kit look like? It contains the following:

Single Ramps

Obviously, every loading ramp kit will come with at least two single ramps; one for the left side and one for the right. Our kits come with two sets of 18″ x 96″ ramps with a capacity of 23,500 pounds. These ramps are sturdy enough to be used as load levelers for timber loads as well.

Adjustable Stands

Ramp stands provide the support underneath while loads are driven up the ramps. They are also sold in pairs; one for the left side and another for the right. Our ramp stands are adjustable from 18 to 24 inches to account for different trailer heights.

Aluminum Skid Seats

Skid seats are mounted on the back of a trailer to provide an anchor for locking ramps in place. Once locked, ramps cannot pull away from the trailer. They are also sold in pairs; one pair for the bottom deck and another for the upper deck.

Ramp Hangers

Ramp hangers make it possible to carry trailer loading ramps from one job to the next without taking up valuable space on the flatbed. They are mounted to the main trailer frame using heavy-duty bolts. The ramp hangers in our kit are double hangers, meaning there are slots for two ramps. Two sets of hangers would allow for carrying a total of four ramps; two on each side.

Ramps Stand Hangers

If you are going to carry loading ramps on the trailer, you’re going to have to carry ramp stands as well. A good trailer loading ramp kit includes one hanger for each stand. Again, these hangers are mounted on the main truck frame, either in front of or behind the ramp hangers.

Ramp Wedges

Finally, ramp wedges are fixed to the lower ends of ramps to provide a smooth transition between the ground and the ramp. This allows for smoother loading while also reducing the risk of ramp movement during loading. Most loading ramps require the use of a wedge.

Mytee Products offers flatbed truck drivers a trailer loading ramp master kit that contains all the above components along with a few extras. For example, we also include a lightweight dolly that makes moving ramps around nearly effortless. Using a dolly is a lot less strenuous than trying to carry unwieldy ramps without assistance.

Please feel free to check out our ramp kit at your earliest convenience. Our website details everything that comes in the ramp kit for your convenience. If you do not need the entire kit, we do sell individual pieces as well. Rest assured that all our loading ramps and accessories are made right here in the USA to the highest possible standards.

If you’re unsure about anything included in our ramp kit, please don’t hesitate to ask. We want you to be fully informed and completely comfortable with your purchase before you buy.
