My car trasporter trailer project with pics

Autoflock Motorsport - 5/5/15 at 09:59 AM

Well I managed to get a bare trailer chassis off a user on here ho lived not far from me. A lot of stuff was included with the trailer so it only needed bolting together and a few lights, brakes, ramps etc adding. Here is how I got on:
sorting the brakes and preparing the lights

Light mounting plates welded on

now to sort and the drums

Had to remove the hitch to re arrange the brake compensator mechanism

Compensator done

Lick of paint with help from her in doors

Folded some cheq plate to make the ramps

Some more steel

Ramps storage

Lights starting to work

All done

This is intended as helpful advice, and not as criticism. I do hope that you take it as it is intended.

Hi.

When a car sits on a trailer all the weight is on the front and the back, and the strain is in the centre. Think see saw.

The chassis needs to be deeper and stronger in the middle so the trailer doesn't break its back. My Alko chassis does
just this, in fact that's why there are chassis mount holes in your axles that you haven't used.

IMHO you should either add an inverted angle, tapered off to nothing at the front & back; or, add 3 smaller angles
bolted to the axle plates and bolted or welded to the main angle at the front & back. ( see pic )
Possibly add short upright joiners.

This mod IMHO will double the strength of the trailer for little extra weight.

Paul,

You are absolutely correct and I spent quite a while designing the trailer and ran through a few different designs. What you see here was the most simple construction that I came up with and i did calculations to verify the loading on the sections in order to get rid of the extra bracing.

Its not perfect by any means but it is however fit for purpose, just avoid pot holes!!!

With that in mind there is absolutely no problem adding the bracing in at a later date if there is a little creep.

Now that's a scary way to drive a trailer.....
Bit tough to swerve to avoid a pothole with a loaded trailer!

I'd just add the strengthening rather than drive constantly thinking it'll be fine if I miss the potholes, but each to their own I guess....

Good luck!

Thats very helpful, will be adding in some steel as per your drawing over the next few weeks time permitting.

If it helps, a pic of my Alko bare chassis.

I borrowed the wheels just to get it home. Now fitted with 10 x 185's.

My axles look very similar to yours.
