Can Two Ramp Springs Be Used On Each Side Of Trailer Ramp

Updated 06/30/2017 | Published 06/29/2017

Question:

Is there a guideline on installing one or two ramp springs? I have a 1998 Texas trailer 20 + 5 heavy equipment trailer for moving my backhoe. The ramps weigh around 300+ lbs each. I want to install the helper springs 1 1/2 dia, but need to know if I need one or 2 springs per side. Also, what can I do to increase the height of the ramp to line it up with the dovetail when ped? Currently, there is no eccentric to raise the ramps to the dovetail height. When the ramps are lowered, they sit about 3 below the dovetail, making for a bumpy ride trying to load my tractor. Thanks so much.

If you are wanting to use ramp springs like part # RS16933LH (left hand), and part # RS16933RH (right hand), you will want to know the diameter of your trailer hinge pin. These springs are designed for 1-1/2 inch diameter pins. The springs have 2,000 lbs of torque, so they should be able to handle your 300 lb ramps with no problem. I would only use one on each ramp and see how it performs before adding a second spring.

If you send me a photo of your ramps and how they are attached to the trailer I will do some research to see if we can find out how to raise the ramp as you mentioned.
