motorised jockey wheels

The motorised wheels need a fair bit of weight sitting on them to drive a van up an incline.

The other type with a ribbed roller running on two of the van main wheels work better for that type of work.

A friend tried both before he settled on the ones that drive the main van wheels.

Johno,

I agree with Notso (this could only happen in Australia):

I used an easy mover type jockey wheel to get my 16ft Jayco out of my driveway and it will work but only on a very slight incline. The lack of weight over the jockey wheel is the problem.

Johno - I'm not sure what % of incline or gradient you are talking about - but remember, if you're driving a van up an incline, you need to have a pretty sizeable weight of device driving it.
If you used a motorised wheel, and it lost traction, and the van took off, you have no control then whatsoever, as regards where it goes.

As a result, full control when pushing the van up that incline, is what you're seeking - and that can only be done by a push device (or vehicle) that nearly approximates the weight of the van.
The alternative is to set a solid pull point in the garage floor or wall, and attach and use a portable electric winch to pull the van up the incline.

I have a 2000lb electric winch that I carry around in an old Army ammo box for pulling disabled items onto my tiltable tandem car-carrying trailer.
I have an attachment point on the front of the trailer where I sling the winch from, to pull disabled equipment (that can still roll) onto the trailer.
It works a treat, and it can pull a 2 tonne vehicle easily up a 30 degree incline.

I would never consider pushing a heavy item up an incline with anything less than something at least around 2/3rds the weight of the item I'm trying to push.

Cheers, Ron.

Johno,
Have a look at this lifting winch. It could be used for pulling. Radio control, auto locking and the pull ratio could be multiplied by the use of extra sheaves.

You would just need a backup safety brake man ready if things turned pear shaped.

I posted a review of one type on the MySwag forum:

Another diy design is posted later in the thread which may be more suitable to you application.

I have a 4 wheel boat trailer that I have to manoeuvre into a small carport which also requires a 90 degree turn . I purchased a 'Parkit 360m' [I think there were 3 sizes]
It connects directly onto the trailer ball, it is driven by a 12v electric motor, driving 2 large rubber wheels . To complete the 90 degree turn I place 2 'Hydraulic vehicle Positioning Jacks' under the back tyres and it turns easily .
I biggest problem I have with the PARKIT is that it is 'fiddly' to connect to the ball of the trailer - [ I might need more practice !]. There is a Parkit importer in Melbourne- there was website with more details
