Review from a similar M3 Ramp Springs in Trailer Ramp Springs


Directions can be a little confusing, since I installed this on a she door, not a enclosed trailer. Left and right are painted and all was clear except on which way cable winds on drums, according to rep you wind it thru front unlike a garage door. Called to confirm because drums are labeled r and l but are reversed as your installing it,which prompted a call call. 506038


Comments
Thanks for the follow up Brandon. This system is set up so that when you are in the trailer or shed in your case looking out of the down door, the end with the black cable drum and the red winding cone should be on your left. If you are not comfortable or experienced with the installation of torsion springs, it is highly recommended that a local garage door company complete the installation.

Review from a similar M3 Ramp Springs in Trailer Ramp Springs


Yes, I know it is recommended for personnel whom have utilized a torsion spring before, but I am definitely on the stubborn side. Before I could contact my local garage door guy, I pulled this out of the box to see if I needed to make a modification. So, I shortened the bar. I then noticed that the old one had to come down. Then I happened to notice that the placement of the plate almost lined up to the old one. Two minutes later, I was too far in the installation to not finish this job myself. Total time it took me was 1hr45min. 15 of those minutes were spent unwinding the cables because I didn't read the directions to put it on with the ramp down. Other than that, it was a breeze. Customer service was also the most amazing experience ever. I called to make sure I was ordering the right part from Pace and they informed me that my trailer was to old and to go to a recommended dealer 30 minutes away. etrailers crack staff told me to go out and measure my trailer twice, to make sure it would fit. Voila, 2 minutes later, i knew I had the right part. 480071

I installed this on a heavy fold-down ramp door that I made for hauling my Jeep in an enclosed trailer. The ramp was so heavy that I couldn’t hardly lift it by myself. I bought the dual spring model because I thought I needed it, but I don’t. One spring is all I needed. I can now lift the heavy ramp door with one hand. 728987

Ask the Experts about this M-3 and Associates Trailer Ramp Springs

  • Bifold To Single Door Charmc Gooseneck Enclosed Trailer Conversion
    Depending on your dimensions, the double torsion springs fit 96 inches wide, # CB250D96SHD or the 81 inches wide, # ERS120D81 would be used. Installation requiring winding torsion springs can be very dangerous if you don't have prior experience. A local garage door company can install this system if you're not confident. A retention device for the door when it is up such as # 383200 can also be used horizontally or vertically.

  • Recommended Ramp Door Spring and Winch for Raising or Lowering
    The ramp doors will use a spring system like # CB250D96SHD. Then you can use a winch like Bulldog Winch Trailer Winch - Wire Rope - Hawse Fairlead - 3,400 lbs # BDW15017 to help raise and lower the door.

  • Can the Enclosed Ramp Spring CB250D96SHD Be Trimmed Down to 81 inches
    Yes, you could trim down the ends of the Enclosed Trailer Ramp Spring # CB250D96SHD to take it down to 80 inches minimum. If you need anything shorter, then I recommend using the 94 inch # 362SW81 instead to give you a few more inches to play with.

  • Rear Ramp Door Spring Assist Maintenance
    The Enclosed Trailer Ramp Spring # CB250D96SHD are just like garage springs. There is nothing really required to maintain them other than visual inspection and light grease on the moving parts. If they lose tension or require cable maintenance, it is recommended to have a garage door professional do the work on them due to the high tension.

  • Would Enclosed Trailer Ramp Spring # CB250D96SHD Be Rated High Enough for 92 x 74 inch Ramp
    The Enclosed Trailer Ramp Heavy Duty Spring - Dual, 96" Wide # CB250D96SHD is rated for doors up to 250 lbs. I'm confident your ramp won't weigh more than that unless you've added weight to it beyond the decking.

  • How To Choose the Correct Dual Ramp Door Spring for an Enclosed Trailer
    In order to replace the ramp door spring on your enclosed trailer you will need to measure the distance between the mounting brackets. For example, the Enclosed Trailer Ramp Heavy Duty Spring part # CB250D96SHD has mounting brackets that can be adjusted to sit 80" - 96" apart. If you have mounting brackets outside of this range then please just let me know what that is so I can make sure your get the correct replacement ramp door spring.

  • Ramp Spring Recommendation for 72 inch Wide Door that Weighs 160 lbs
    The whole assembly (96 inches wide) would be too long to trim down and still fit. I'd recommend going with the slightly smaller # 362SA7, which can be trimmed down. The spring has a capacity of 150 lbs. That means you will need to slightly support the door but it will be very minimal and will allow great assistance with operation. The # CB250D96SHD although rated for up to 250 lbs is also only able to be cut down to 80 inches. We strongly recommend having a professional overhead door...

  • Can the Enclosed Trailer Ramp Spring # CB250D96SHD Be Used to Replaced Haulmark Trailer Ramp
    The Enclosed Trailer Ramp Spring # CB250D96SHD has a 250 lb capacity and can be used on heavier trailer doors like what you have. If only one side of your spring is broke this would replace both sides. The installation instructions for this product are recommended for individuals who have experience winding torsion springs. If you have not worked with a torsion spring system before, we recommend contacting a local garage door company to install this system.

  • How to Determine Required Capacity of Trailer Ramp Torsion Spring
    On a hinged trailer ramp the hinges will carry a varying portion of the ramp weight depending on the ramp's position. When fully opened/extended the torsion spring will actually be holding more of the ramp's weight that when it is almost fully raised. In the fully vertical position more of the ramp weight is on the hinges since the ramp will be more directly over them. The M-3 Enclosed Trailer Ramp Spring # CB250D96SHD can lift 250-lbs of ramp weight. You can use a scale to weigh your...

  • Can Enclosed Trailer Ramp Spring # CB250D96SHD be Cut Down for an 88 inch Wide Ramp Door

    The installation instructions for the Ramp Spring part # CB250D96SHD are recommended for individuals who have experience winding torsion springs.

  • Availability of Enclosed Trailer Ramp Spring Like # CB250D96SHD With 300-lb Lift Capacity
    The M-3 Enclosed Trailer Ramp Spring that you referenced, part # CB250D96SHD, has a 250-lb capacity and this is the highest-rated of all such available items. If you decide to replace your ailing winch with a new one I suggest a brake winch or a worm gear winch since both of these types will prevent the ramp from free-falling. A economical brake winch is the MaxxTow Positive Lock Hand Winch # MT70176 that comes with a 25-foot strap and that has a 1000-lb capacity. For a worm gear winch...

  • 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...

    The M-3 Enclosed Trailer Ramp Spring # CB250D96SHD uses cables that will be plenty long for your application on a ramp door that is 90-inches wide x 96-inches tall. That is precisely the type of trailer installation for which this item is intended. It will work for you so long as the ramp does not weigh more than 250-lbs. The main tube is 96-inches long but it can be cut down to as short as 80 inches to fit your trailer width. It comes with mounting brackets to install it to the trailer...

  • Trailer Ramp Door Is Hard to Open and Close, Do the Torsion Springs Need to Be Replaced
    It could be that the springs are worn out and need to be replaced with either new springs or a new system such as # CB250D96SHD. Inspecting, working on, and/or installing these systems is not something you would want to do yourself because they can be dangerous (the springs are under a lot of tension). I recommend having a garage door company take a look at it to determine if anything can be done to fix the existing system or if a new system is needed.

  • Are Mounting Brackets on Enclosed Trailer Ramp Spring # CB250D96SHD Adjustable
    Yes, the mounting brackets on the Enclosed Trailer Ramp Spring, # CB250D96SHD, are adjustable so you should have no problem using the existing weld points on your trailer. Please keep in mind that the installation instructions for this product are recommended for individuals who have experience winding torsion springs. If you have not worked with a torsion spring system before, we recommend contacting a local garage door company to install this system.

  • Distance Between Strap Anchors for M3 Ramp Spring # CB250D96SHD
    You'll want to anchor the straps that the Enclosed Trailer Ramp Spring # CB250D96SHD uses on the ramp door right at about 80 inches in width. This is the distance between the reel centers of the ramp spring.

  • Could the Ramp Spring Part # CB250D96SHD Replace a Smaller Ramp Spring
    The closest ramp spring we have to what you have is the part # CB250D96SHD that you referenced which is slightly larger than your current setup but could still be made to work. It can be cut down to a minimum length of 80 inches. We strongly recommend having a professional overhead door technician install the spring for you. The spring needs to be tensioned, and if it lets loose accidentally it would fling tools at high enough velocity to easily kill someone.

  • Where Is Door Bracket Mounted When Installing Enclosed Trailer Ramp Spring CB250D96SHD
    The # CB250D96SHD is designed to work with trailer ramp doors that open from the top and when fully opened create a ramp used for loading the trailer. The brackets that are attached to the door are typically placed at the top of the door(top of door when closed). The bar that has the springs and drums attached is mounted on the header above the door in the trailer just like a garage door spring assembly. If you are not accustomed to adjusting the springs on a system like the # CB250D96SHD...

  • When Does the Spring Tighten and Loosen on an Enclosed Trailer Ramp Spring
    On a torsion spring like that on # CB250D96SHD when the door is opening downward the line is spooling out and the spring will get tighter. When the line is spooling in, closing the door, the spring will relax or get looser. As such if you have not worked with torsion springs before we strongly recommend having a professional perform the installation. A local over head door company should be able to help.

    Yes you can cut the shaft on the 96 inch wide ramp spring, # CB250D96SHD, to fit your 92 inch wide trailer. The shaft is made of steel tubing so the proper saw or power saw blade would cut through it. Be sure to get a straight cut and file down the rough spots. Regarding installation, a professional with experience should install this in your trailer. Torsion springs are under a lot of tension and can be dangerous if you do not have experience with them.

This spring is 96 inches long and should work well for you since your trailer is 8 feet (96 inches) long. For the hinge, I recommend the Continuous Hinge - Steel - 5" Wide - 96" Long # PLR844.

If you have an enclosed trailer you could use the part # CB250D96SHD as an overhead torsion spring to help lift the ramps. This is rated for 250 lbs capacity for an enclosed trailer ramp.

    The part # CB250D96SHD has a total weight of about 45 lbs. It has a lifting capacity (spring capacity) of 250 lbs. That means it can provide up to 250lbs of lifting assistance depending how you wind it.

If you have not worked with a torsion spring system before, we recommend contacting a local garage door company to install this system.

  • Can Mounting Brackets be Moved on Enclosed Trailer Ramp Spring
    It is not recommended to adjust any of the parts attached to the main tube of a spring like # CB250D96SHD because of the tension on the springs. Only a certified garage door installer should make adjustments. While it is possible to move the brackets it would be easier to just move the top L-brackets to point out instead of in or just replace them with longer L-brackets to fit the mounts you have.
