[SEL] Tandem Trailer

[Bob Jacobs]

Me again Andy,

On the ramps,  I used  1" diamater Drill rod attached to a bracket on each
end and welded on the back of the trailer end to end 
}----------{}----------{    something like that, with a piece of pipe cut to
the width of the ramp and welded to the ramp slid over the drill rod. 
Proved to be infinately adjustable from only a couple inches between them to
almost the full width of the trailer.  There's a couple downfalls to this
method.  If the trailer is fully loaded you end up transporting it with the
ramps sticking straight up in the air and catching all the wind,  sucks the
ole' fuel milage way down, but if you can figure it out you can hinge the
ramps in the middle and fold them up as you prepare to stow them on the
trailer deck.  

The next trailer I build I'll use a similar method for the ramps, but rather
than welding them to the mounting brackets I think I'll drill and tap the
ends of the drill rod so that I can still have them secure but also be able
to remove the ramps from time to time as needed.

Hello All, I remember a while back, there was talk about Tandem Trailers.
I'm in the process of building one, and I need some help with the
configuration of the spring hangers and a method/style of a tailgate. The
springs I've seen, some are hanging down and some are up on the shackle
side, with the spring shackle in the up position it looks like the rocker
will hit the spring, the way I'm inclined to do it is have the spring
hanging down from the rocker, and the shackle plates angled back, so when
the weight comes off ( i.e. going over a bump) the axle, the shackle will
hang straight down and won't flip over above the rocker? Also where to mount
the Rocker mount in the centre of the main frame or just back of-centre, I
think the idea is to have a positive weight on the draw bar, if I have the
rocker mount in the centre of the frame, won't the weight of the draw bar
(and spare wheel) give it the correct positive weight I need? The Tailgate,
I'd like to incorporate a ramp in it as well, so it will be fairly long, or
high when in the up position, how would I do the hinges? I don't have an
idea on this one, I was going to build the trailer, and then work out what
to do. This trailer is going to be use for my engines and/or a Section Car
(Speeder) or would it be simpler to just have two ramps, but how do I attach
them to the end of the trailer easily? to take the different widths of the
Engine trolleys. Any help would be great.
