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 at least 2-1/2 inches of space between the ramp and trailer. At this time, the ramps springs, # RS16933LH (left hand) and # RS16933RH (right hand) are the only size that our manufacturer offers.

Since you have an enclosed trailer, you may be interested in our overhead torsion spring systems. We carry double and single torsion springs. The double torsion springs have a cable for each side of the door and a single torsion spring has one cable. The double torsion springs are available in 96 inches wide, # CB250D96SHD, and 81 inches wide, # ERS120D81.

Keep in mind that installation of this product is recommended for individuals who have experience winding torsion springs. If you have not worked with a torsion spring system before, we strongly recommend contacting a local garage door company to install this system. The torque involved in winding the spring can be extremely dangerous.

Your door is a little too narrow for the spring you mentioned but we do have a solution that is the correct size with the part #CB250D96SHD which has a 250 lb weight capacity and is for ramp doors that are between 80 and 96 inches in width.

Answer 5

For a 200 lb trailer ramp door we have the Conventional Ramp Door Spring part #362SA8HD which would work great as it has a 230 lb capacity. You'd need to have a professional wind it for you but it would easily work great for a 200 lb trailer ramp…

Answer 6

To test the weight of your ramp door, you will want to get the door all the way down to the ground and then on a scale of some kind (a bathroom scale can be used for this if it's the only thing available). This will be when the door is at its…

Answer 9

The spring with the black cable drum should always be mounted to your LEFT, standing on the inside of the trailer looking out. This is very important for proper operation. Dual spring systems, like #ERS160D96, have a red-coned and a black-coned…

Answer 10

Hey David, I am not totally sure which two springs you are comparing but just because a dual spring torsion ramp door spring like the part #ERS160D96 has two springs doesn't always mean it has more capacity than a single spring. The springs can…
