Customer Question

I want to make trailer ramps out of 2" x 12" douglas fur and then add aluminum channel to each end of each ramp. The ramps would be 60" long. I want to push up a 4,000# ***** roller or drive my 4,000# ***** up the ramps. The height trailer is 15" to ground.
What section of Aluminum channel will allow me to do this safely.

DearCustomerI do not have any pictures. If I did take a picture it would show a utility trailer that is 10" long on an axle rated at 3,500#. the trailer is flat. I have used 2 planks of douglas fur with a steel lip bolted on one end of each plank. The steel lip sits on the edge of the trailer. The other end of the planks are on the ground. The difference between the ground and the bed of the trailer is 14". The length of the douglas fur planks are 60". I would like to support the douglas fur planks so they will reliably hold 4,000#. I have thought of placing aluminum channel over each running length edge. Or bolt a 3" Aluminum I=beam on the bottom of each plank and it would run the length of the beam. I like the aluminum channel idea best. How thick do the channel walls have to be to accomplish this or what is the lbs./foot of the channel that will accomplish this.Chuck Vierthaler
