Expert Answers about M-3

  • Recommended Ramp Door Spring for 7 Foot Wide Ramp
  • For your 7 foot wide ramp door, I recommend the Enclosed Trailer Ramp Spring - Dual Spring, 81" Wide # ERS120D81. This will give you a dual spring assembly capable of lifting 120 lbs, so you would need to give a little assistance in raising and lowering. Another option is to use the Enclosed Trailer Ramp Spring - Dual, 96" Wide # ERS160D96 which you will cut to length and has a capacity of 160 lbs.

  • Recommendation for Enclosed Trailer Ramp Springs for a 7 Foot by 14 Foot Enclosed Trailer
  • The system that will probably work best for you is the Enclosed Trailer Ramp Spring - Dual, 81 Inches Wide, # ERS120D81. I went out to the warehouse and measured the distance between the mounting brackets. It is 64-1/2 inches from bolt hole center on one bracket to bolt hole center on the other bracket. The overall length is 81 inches. Since you have a 7 foot (84 inch) wide trailer, the 81 inch assembly should be a good fit. An assembly that measures 96 inches wide will be too long to...

  • Will Adding Enclosed Trailer Ramp Spring ERS160D96 Double the Lifting Strength of My Trailer Door

If you determine that the double spring system is too large, then I...

  • Recommended Ramp Door Spring for 8 Foot Wide Enclosed Trailer
  • You'll want to choose a spring that's the same width as the ramp door. I'm afraid that the # ERS120D81 you mentioned would be too narrow. You'd want to use # ERS160D96, which is 96 inches wide. You'll have to take about 2 inches off each side of the pipe, but this would be your best bet. We HIGHLY recommend having the spring installed by somebody who's experienced with torsion springs. Tensioning the spring is a dangerous job that shouldn't be undertaken by somebody who's not familiar...

  • 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.

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...

  • Could the Ramp Spring Part # ERS160D96 Replace a Smaller Ramp Spring
  • The closest ramp spring we have to what you have is the part # ERS160D96 that you referenced which is slightly larger than your current setup but could still be made to work. 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.

  • Can the 96 Inch Wide Enclosed Trailer Ramp Spring be Trimmed to Fit a 92 Inch Wide Trailer
  • Yes you can cut the shaft on the 96 inch wide ramp spring, # ERS160D96, 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.

  • 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 # ERS160D96 can lift 160-lbs of ramp weight. You can use a scale to weigh your...
