I have noticed out gate gets real heavy lifting up and down all day. I have seen these and figure they will help alot. Also I can make one myself probally. If anyone has any detailed pictures or how to design one that would be great

Thanks,

I used a 150lb garage door spring, it's not enough, it helps alot but it still takes alittle effort, a 175 spring should do the ticket.

Garage door spring, 10ft of braided steel line, a tube to house it so it doesn't flop everywhere, and some form of pulley or eye bolt to run the line through at the end of the rail where the gate closes at.

I forget who it was that posted a really nice set up awhile back, they used square tubing and made little aluminum rollers for the end (just drilled 2 holes through the tube and put bolts through with small aluminum pipes over the bolts to act as rollers), he notched the center of the tube so the cable wouldn't rub, bolted it down to his rail on the trailer and bolted the cable to the gate via an eye bolt.

I also used a 150 lb garage door spring and I would go up to the next size up. Other than that... do a search and you will find plenty of pics.

How did you attach the steel cable to the spring? Just loop through and cable clamp?

SO on the other end what you secure with? 3/4 Bolts and Nuts or Threaded Rod?

Are you talking about attaching it to the trailer gate?

Pop a hole through the side of the gate and attach it to this...

Opposite end of the spring far end.

I put a large bolt through and ziptied the spring down for a temporary fix.

If you use a tube to house the spring, you would run the bolt down through the tube through the end of the spring and through the rail on the gate. Then it will hold everything down.

Yes, loop the cable around the end of spring and use "Clips and Thimble" for wire rope. They are designed for use with metal cables.

I bought 4 "sheaves" from Tractor Supply and had a machine shop make the brackets for the end of my trailer. I used pvc pipe to house the garage door springs. I used one on each side because I had a 5 foot high gate and it was very heavy. Anyway, someone ran into me and totalled my trailer 2 weeks ago. I ordered a new trailer with a suspension spring assist and took everything off my trailer so I have them for sale without the brackets because they were welded on.

Yeah thanks for the pic Tharrel saw your thread on your trailer. You came out pretty good on that deal. Except maybe the bumper.
