Our camper trailer came with a standard 120mm
solid jockey wheel which is very useless on sand or loose dirt with
a fully loaded trailer as it tends to sink in the ground. I wanted
to buy one of those inflatable big jockey wheels which are 250mm and
wide footprint, perfect for that kind of terrain, but at $130 a pop
was a bit expensive so I decided to make my own…even better a twin
jockey wheel, like the ones you see in heavy caravans.
When I tried to buy a pair of wheels they were
$48 each, but at the same shop they had a trolley with identical
wheels for only $25…a no brainer!!! I bought the trolley for $25, a
180mm M16 galvanised bolt and some washers for $8. A total of $33. A
lot less than the price of one wheel.
First I removed the bolt holding the existing
wheel and cut a piece of gal pipe the same length as the existing
gap to give the new setup some strength by not allowing the vertical
supports to bend with lateral forces. I you have a welder you could
weld the pipe to the supports which will give you the ultimate
strength. I do not own one, so no welding on this prototype.
I drilled a 2mm hole at the end of the bolt to
allow a retaining pin to hold the new axle in place. You could also
use the existing trolley axle and just trim it down.
Inserted the new wheel and bolt through the
spacer and put another wheel on the other side, a washer and
finishing up with a retainer pin to secure the assembly (as a matter
of fact, I did put two pins at 90 degrees angle, an overkill but you
can never be too cautious!!!)
As there are two wheels with a maximum load of
180kg each, they do not even feel the weight of the trailer…
