Small jack for trailer
My car uses run flat tyres which you can still drive on once punctured so I have no jack in the boot. I carry a spare wheel on the trailer though but was wanting to come up with a simple 'rocker' jack I could fold and fix to the trailer. I imagined a triangular style unit when unfolded, which you would fit under the axle, then drive forward a little to lift up the axle in order to get the wheel off .. any ideas , or should I just get me coat ? ![big grin](https://www.rib.net/forum/images/smilies/biggrin.gif) .....

How about a small scissor jack from a car breakers yard?

Why not get a small bottle jack? They take up very little room.

I'd be wary of keeping a jack on the trailer: easy to steal and easy for others to use to steal wheels.
How about this to keep in the car: http://www.halfords.com/webapp/wcs/s...egoryId_165727
A bottle jack for £12.99.
1.5 tons should lift your size boat ('cos the need to change the tyre is sure to occur when the boat is loaded) but there's a 4 ton one also available for £4.00 more.

if you have a double axle trailer use a trailer-aid, you drive the other wheel up onto the lift and then change the other wheel, works a treat

I carry what Downhilldai suggested, a scissor jack.
But when doing bearings etc at home, it's a 3tn Trolley jack.

Yeah I see where that would be a problem depending on what surface you were on, in which case the contact feet could be made a bit more agressive to enhance the grip .. but its the sort of thing I was thinking about ![thumbs up](https://www.rib.net/forum/images/smilies/thumbs.gif) It was an old Massey Ferguson jack lift from the 30/40's that got me thinking about this

I have a small 2.5 tonne trolley jack with a detatchable handle and sits in it's own little case. It is heavy but very compact and cost about £15inc from Macro's

I have a 3 ton bottle jack. Haven't had to use it. Yet.
I would like to carry a floor jack, like Hightower, but they take up too much room in my truck.

I'm trying to get away from anything too heavy, or with bits to go wrong as I want to leave it attched to the trailer, which I tow with 2 different vehicles. I wish I had a bit more time to design one myself ![roll eyes](https://www.rib.net/forum/images/smilies/rolleyes.gif) , as manufacturing it is no problem, I've got all the gear for that. I like the idea of the easy lift one, and its alloy too so no weight. I thought about how you could stop the unit slipping on the road .. basically its a grip/slip problem with weight transfer being the key, and I think I can get around that easy enough, different base surfaces would defeat it though, ie definately not sand or a grass verge, but if your tyres humped anyway, you should be able to tow to a suitable surface

And it may/should fit inside the trailer's spare wheel.
