Ramp Door Spring Recommendation for 200 lb 90" Wide Door

Question

Question:

I need a trailer ramp door spring for a 2018 Lark cargo trailer. 20foot x 8 The trailer model VT8x20TA. The ramp door measures 90x74. Im guessing the door weighs 200lbs. It has 3/4inch plywood base. Can you tell me which ramp spring model I need to purchase?

Hey Rick, thanks for reaching out!

I'm guessing the 90" dimension is the width of your trailer door so for your application I recommend the Conventional Ramp Door Spring # M394FR because it has a 185 lb weight rating. This means that you'll still need to put a little effort into lifting the door, but you'll only be handling 15 lbs of it if your door really does weigh 200 lbs.

We have some higher rated springs but that can be dangerous since the spring can close the door by itself if it's rated higher than the door.

Our ramp door hinge selection is limited to just part #PLR1902, which can be welded in place. As for the springs, we have a bit of a selection that you can narrow down depending on the width of the ramp door and the capacity needed. For example, part…

Answer 8

I would think the 185 lb spring would work best like the part #M394FR that you referenced. 185 lbs would feel really hard to pick up off the ground so I would assume this would be right at the correct capacity to make sure your ramp is easy to pick…
