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.

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

Ask the Experts about this Redline Enclosed Trailer Parts
Do you have a question about this Enclosed Trailer Part?


  • 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...
    view full answer...

  • 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...
    view full answer...

  • Recommended Ramp Springs for Heavy Horse Trailer Ramp
  • If your ramp is really heavy, you can use the 2K springs like # RS16933LH and # RS16933RH for the matching set. These will be the strongest option we carry. If you just need some assistance in lifting a ramp that is up to 160 lbs, you can use the enclosed trailer ramp spring like # ERS160D96. This spring is similar to a garage door spring and it is recommended to have a garage door tech help with winding these torsion springs.
    view full answer...

  • 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.
    view full answer...

  • Big Tex Trailer Ramp Replacement Springs
  • We only carry the springs for those heavy duty style ramps. For the springs we have the Ramp Spring - 2K Torque for 1-1/2" Shaft - left hand # RS16933LH and corresponding right hand # RS16933RH. The other parts will need to be either straightened or replaced and custom welded into place.
    view full answer...

  • 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.

  • 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. 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 would be a better option. We...

  • Availability of Enclosed Trailer Hinge Ramp Springs
  • I do believe we have the springs that you are looking for, but they are not part of a kit. We have a left, # RS16933LH, and a right, # RS16933RH. These springs are for a 1-1/2 inch diameter shaft. They will need to be welded into place with the two arms facing down and flat against the trailer and door surfaces. Each spring is rated for 2,000 pounds torque to help with lifting and lowering ramp doors on trailers.

  • Can Ramp Spring # RS16933RH Be Mounted in Center of Ramp
  • Yes, if you wanted to install the ramp spring part # RS16933RH in the center of a ramp it would work in that orientation. I attached a picture that shows a ramp with the springs mounted more towards the center.

  • What is Actual Torque Rating for Redline Ramps Springs # RS16933LH and # RS16933RH
  • The Redline Ramp Spring you referenced, part # RS16933LH, and the matching right-hand spring, part # RS16933RH, are intended primarily for use on equipment trailers, such as those used to transport a skid loader for example, not for utility-type trailers. These springs have an inside coil diameter of approximately 1-1/2-inches (and are intended for a 1-1/2-inch shaft). The wire diameter as measured with a digital caliper is 0.465 inches. I checked the Redline catalog and with my contact...

  • Recommended Small Ramp Door Lift Assist
  • For your steel stairs on your ramp, I recommend the Enclosed Trailer Ramp Spring - Single, 66" Wide # ERS80S66. This can be trimmed down to 45 inches but no shorter. That would limit you to one cable for your ramp but it gives you some lifting assistance. You can shorten the spring for a customized system with two cables. These springs operate like garage door springs, so having installation assistance from a professional would be wise to avoid injury. This system is about 9.5 kg before...

  • 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...

  • 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...

  • Ramp Lift Springs for a Trailer with a 7 Foot Long and 2 Foot Wide Steel Ramp
  • If your 7-foot long and 2 foot wide ramp is heavy enough then you would use ramp springs such as # RS16933LH and # RS16933RH. But each of these springs produces 2,000 foot pounds of torque so they may be way too strong for your ramp. If you can tell me how much the ramp weighs I can determine if these springs would be a good fit. Based on the material and size I am willing to say the ramp is probably too light for this type of spring. Another option that could work for you is the trailer...

  • Replacement Trailer Ramp Springs
  • We have several hinge pins like # HP412G that I have linked for you, but it sounds like you need actual springs. We have some heavy duty ramp springs like # RS16933RH and # RS16933LH if you happen to have a heavy duty equipment trailer like what they haul tractors and other large equipment on. For an open utility trailer you may be able to use a tailgate assist like # RA-27C. Or for an enclosed trailer we have springs that are similar to garage door systems. I have linked those as well....

  • Recommended Ramp Door Spring for 6x12 Enclosed Trailer
  • 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 enclosed 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 hinge pin and requires...

  • Recommended Ramp Springs For Heavy Equipment Trailer
  • The Redline Ramp Spring like part # RS16933RH and part # RS16933LH will help with lifting the ramps you said you are building for your trailer. I would recommend 1 spring for each ramp. These springs are made of steel alloy, these springs provide approximately 90 degrees of deflection and are designed to help lift a ramp with 2,000 pounds of torque.
