Video Transcript for Ramp Springs Review

Speaker 1: Today, we're going to be taking a look at, and showing you how to install ramp springs for the 2000 pound torque rate for inch and a half shafts. The left hand side is part number RS16933LH, and for the right, you'll need part number RS16933RH.Now, these springs are designed to aid you in lowering and lifting these heavy ramps. If you don't have any springs installed, you know it can be quite a bit of a pain. As you're lowering your ramp down, you kind of have to be under it. You don't want to just let it drop .. Well, I guess you can, but you might cause damage to it, and vice versa.When you're trying to lift it up, you're going to lift up the entire weight.

With the springs installed, they've got a 2000 pound tension rating, so as we lower the gate, as we raise the gate, it's going to be much, much easier.Now, this is what I would call a medium/heavy duty utility type trailer. We'll also show you on a very heavy duty utility type trailer, the use of two of them for those much larger ramps, the triangulated style ramps. Those tend to be a lot heavier, so we'll show you that, as well.Just to give you an idea, however your ramp's held in place, you'll want to, of course, unsecure that, and then you'll see our ramp's going to come down much easier. It actually kind of floats there. We'll push that down.

That'll keep it closer to the ground. We can get our equipment on and off, then when it's time to shut them back up, much easier process than what you're probably used to, especially if you don't have springs, or if your current springs aren't in good working order.You can see our old spring. It's become worn, and it's not near as effective as it was. You see how that's pointing off, kind of in that rearward direction It just means it's been fatigued over time, so we're going to be able to replace it with a new spring. It's going to give us much more effect.Now, the left hand and right hand is going to determine which side of the pin you're going to be putting it on.

If you want it on the right side, you want a right hand spring, and if it's going on the left side, you're going to want your left hand spring.To ensure we get years of great service out of the ramp springs, they're made of a high quality alloy spring steel, so they're going to return to their original position for years and years.To ensure you have plenty of room, we're going to go over the specifications of the spring, just to give you an idea about the size. From outside of our spring to outside of our spring, we've got 2 1/2 inches. Inside and inside's going to be about and inch and a half. From the spring itself, to the end of each arm that sticks out, is going to be 4 inches, so you definitely want to keep that in mind, and make sure that you've got clearance for that, and also that, that spring will make contact with something within that 4 inch range.To begin your installation, you'll need to remove whatever's holding in your hinge pin. It's going to be the large inch and a half diameter pin that runs through here.

In our case, we've got a bolt and a nylon lock washer. We're going to use a 9/16 to get that removed.You also want to hang on to your hardware, because you're going to need this to put it back in. It keeps this pin from sliding in and out. You can see our old spring mounted here. We'll move our pin out, and the idea is to free that up. Now, this ramp's going to be very heavy, and when you pull that pin, it's going to want to fall down. You need somebody to give you a hand, or if you can handle it yourself, however you want to do it, just make sure, as you pull this pin, that, that doesn't fall down and hurt you.Now, we can remove that old spring, set it aside, and replace it with our new one. Now, we're going to be putting our spring on the other side. We've got an accommodation for one here or here, so it doesn't matter how you want to do it. Make sure you get it where you need it, though. Then, our gate hinge is going to go right in between there. As we install it, we can place that pin through.Now, as we replace our ramp onto the trailer, and install our pin, of course, we want to ensure that the pin passes through the middle of our spring, and we also want to make sure that the flange on the ramp goes in between the spring and the flange on our trailer.Now, to finish it up, we'll just reinstall the hardware that we removed to take that old one off.As we said, with these really heavy ramps, they look about the same as the other ones, but they're much thicker steel. It really is a problem, when it comes time to lower them. You're going to have to fight it. You're really going to have to put weight into it, and it can be slightly dangerous. If you have anything underneath there without steel toes on, you'll likely run into something. Same way, going up. Just make sure you get a good hold it.Then, you're putting yourself right underneath them, so if you we're to slip or your hand comes off, it can come back at you. Those springs are going to help us out a lot, with that situation.Now, just like before, we're pulling that pin out, although this time, we don't have any keepers to put it in, so we'll slide this one on, just like that, bring the pin in, a little further, we can get our other one put on.After we have our springs installed, there's a huge difference in the operation of our ramp. We'll go through that same process as before. You could see it actually hold my ramp there. At that point, we just need to press it down a little bit. That's going to make it much easier getting our equipment up and on it.Now, to raise it up, it takes a lot less effort, as well.Overall, our ramps are going to be much easier to use, but a big key is, they're also going to be much safer. That'll complete our look at the ramp springs.

Very pleased with my order, I have ordered twice from etrailer and both orders were shipped quickly and the products were just as described. I would recommend ordering from this company and will do so again when the need arises. 252694

These ramp springs really took the work out of raising and lowering my heavy 3 fold ramps needed for a more long and level approach to our 10 ton trailer. I always looked for help when needing to raise them, now I can almost do it with one hand. It took a little work installing them because the old system had to be rebuilt somewhat. I kept the same 1" pins and used a 1 1/16" ID X 1 1/2" OD sleeve for the springs to work on. They were well worth my time. I`d rate this an excellent product. 359609

My 16 ft mower trailer is loaded with tools from the shop rebuild so I have been having to use my 20 ft implement trailer to haul my sub compact tractor on when mowing the in-laws yard. The ramps are very heavy which was never a problem for occasional use but doing it multiple times a week was getting old so I went looking for a solution. These springs were easy to install and made all the difference in the world. The trailer is now much more user friendly. Wish I had bought them years ago. 806788

I have purchased this same item in the past without any problems. Naturally I thought I would purchase the same item again. They are easy to install and if I need to preload the spring (I usually have slight pressure on the spring when the ramp is straight up) I do this by welding the right size diameter pipe or rod under the tail of the spring. This works fine.. I have already painted them black and ready to pop them on. I would highly recommend the springs for any tailgate or ramp installation. Might also say the package arrived in four days. 760700

  • Recommended Gate/Ramp Assist and Hinge for Trailer Build
    The 2K Torque Ramp Spring # RS16933RH is an industrial strength spring. It is designed for up to 90 degrees of deflection, but most people by hand can cause no deflection at all. It is designed to be used with the LH # RS16933LH, and is for heavy ramps or doors like in the attached photo. I would assume it is too strong for your application based on your wording. You may want to consider a different style spring like the Enclosed Trailer Ramp Spring - Dual Spring, 81" Wide # ERS120D81...

    Choosing a ramp spring for your shed door requires you to know the weight and size of the ramp to ensure the cable is long enough and that the system has the required lifting capacity. A system like the 81-inch dual-spring # ERS120D81 has a 120-lb capacity. All ramp springs can be seen on the included link.

  • Ramp Spring Recommendation for Rear Ramp of Toy Hauler
    You could install a ramp spring like the part # ERS160D96 at the top of your ramp opening to assist the ramp in lifting and lowering. That part number is for a 96 inch wide assembly but if you needed a smaller one we have the part # ERS120D81 which is 81 inches wide. These are torsion spring style assists that would need to be wound by a professional.

  • Replacement Ramp Springs for Horse Trailer
    Horse trailers are enclosed, but they usually don't use the enclosed trailer ramp springs for the safety of the horses. They use smaller versions of our heavy-duty ramp springs. Unfortunately, we only carry the heavy-duty versions at this time, meant for heavy-duty steel ramps like those on equipment trailers or car haulers.

  • Ramp Springs Compatible With 1982 Circle J 2-Horse Trailer
    I have a couple solutions for you, but we don't carry the exact springs you are referring to. I recommend the Ramp Spring - 2K Torque for 1-1/2" Shaft - Right Hand # RS16933RH and Left Hand # RS16933LH. These springs are 11 inches long and have a 1-1/2 inch shaft and are 2-1/2 inches wide. The inner diameter of the coil is 1-1/2 inches. Another option is to use the Enclosed Trailer Ramp Spring - Dual Spring, 81" Wide # ERS120D81. I've attached a photo with all of the measurements...

  • Choosing the Correct Ramp Springs for Enclosed Cargo Trailer
    The springs you mentioned are designed for use on ramps that you'd typically see on a heavy equipment trailer. They're way too stiff to be used on a trailer door. The correct springs for your application will depend on what you are using the ramp for and the width of the trailer. The Ramp Springs you are asking about are best used for heavyweight steel doors on a horse trailer or for an enclosed car trailer. If one man can lift the ramp, a more lightweight option like a torsion spring...

  • 1990 Kingston Trailer Ramp Lift Assist Options
    We have a couple options for trailer ramps springs. The first one will work great if your ramp rides on a 1-1/2 inch shaft. For that you would want the Ramp Spring - 2K Torque for 1-1/2" Shaft - RH # RS16933RH or # RS16933LH. Or we have ramp springs like the Enclosed Trailer Ramp Spring - Dual, 81" Wide # ERS120D81, this spring installs like a garage door spring. There is a lot of tension, so you want to make sure it is installed by someone who knows how to compress these springs...

  • Trailer Ramp Spring for 1-1/2 Inch Diameter Shaft
    We do not have springs for 1-3/4 inch shafts. But for a 1-1/2 inch shaft you can use spring # RS16933RH for the right side or # RS16933LH for the left side. These are meant to be welded on at the straight parts of the springs. Other than these two springs we do not have any others for a 1-1/2 inch or any for 1-3/4 inch shafts.

    We do not carry the spring only for torsion springs on trailer doors. But we do carry the replacement assembly. I have included a link to the options for you to the right. Springs # RS16933LH or # RS16933RH would not work since they are designed for very heavy duty trailer ramps.

    Ramp spring # RS16933RH is designed for heavy duty equipment trailers and it is rated for 2K torque rating. The matching left side is # RS16933LH. For light duty trailers these springs would be way too strong. We do have other options such as # ERS120D81 designed for enclosed trailers. These springs come in a few different lengths from 66 inches wide to 96 inches wide and can be trimmed a little on the ends to fit in between sizes. For open utility trailers I recommend the Rack'em...

  • Ramp Door Spring Recommendation for a 5x8 Enclosed Trailer
    What I recommend for your enclosed trailer is a ramp spring such as # 362SA6 which is 66 inches wide. This is similar to a garage door spring and as such it is recommended to have someone with experience installing garage door torsion springs perform the installation. The spring will not take up the total weight of the door but will assist with 80 pounds of it which is the max capacity of the spring.

  • Ramp Springs for the Front and Rear of a Snowmobile Trailer
    For the rear opening I recommend using enclosed trailer ramp spring # ERS120D81. It has a capacity of 120 pounds. And for the rear I recommend # 362SA6 which has a 120 pound capacity. Professional installation by someone with torsion spring installation (like a garage door company) is recommended because working with these types of springs can be dangerous. You would not be able to use a spring such as # RS16933RH because it produces 2,000 pounds of torque. This would require a very...

These are rated for 2,000 ft/lbs and will do a good job at helping you lift your ramps. I would try checking to see what your current springs are rated for as well.

All ramps springs are shown on the linked page. The installation instructions for this product are recommended for individuals who have experience winding torsion springs.

  • Choosing/Sizing the Correct Trailer Ramp Spring for a Ramp Door
    When selecting ramp springs for a trailer ramp, you will want to know the diameter of your hinge pin and how much space you have available in the hinge. A typical horse trailer or utility trailer ramp uses 3/4 inch hinge pins and would require two ramp springs with a 3/4 inch inner diameter. The ramp springs that we carry fit 1-1/2 inch diameter hinge pins and are designed for use with heavy-duty steel ramps like those on equipment trailers or car haulers. The spring slips over the...

  • Recommended Hinges And Ramp Assist For Steel Ramp
    For your ramp, I recommend a hinge like the Ramp Door Hinge - Steel # PLR1902 or the Dump Door Hinge - Steel # PLR1904-Z. Both of these have a built in zerk grease fitting. Then you can use springs like # RS16933RH and # RS16933LH. If you want further help in lifting and lowering, I recommend the Rack'Em Double Barrel Utility Trailer Tailgate Lift Assist w/ Chain - 200 lbs # RA-27C that can be used on either side or both.
