Lifting 5.4 Tornado off trailer

[Bigmuz7]

I want to sort out the rollers on my trailer and want to lift the boat off, and place it in the corner of my shop whilst I undertake repairs, currently the tubes are flat, theres only a central jockey on her and a YAM 75, I have loads of webbing straps, about 5" wide I can put under the hull and plenty of power to lift her off, should I pump up the tubes first ?, or will they deform too much ... or would it put too much strain on the edges of the hull when I lift if I didnt ?

Worst case I could push it off, but that involves faffing about with loads of protection on the concrete floor .. I dont have any lifting spreader bars or anything, but plenty of height , so the straps wont be pulled together when the load comes on.

What do you guys think ?

This rib should not be too heavy to push, I did push my Humber 5m on the floor once! What you should do is to put a carpet (buy some thick carpets before pushing the boat) and then you can even move the boat in your shop easily without damaging the hull.

I would not inflate the tubes...

Why not build acouple of wooden trestles/bunks to put her on while she's off the trailer?

I had some time a go a similar problem, to get the SR of the trailer.
I built this" http://rib.net/forum/showthread.php?...ghlight=cradle ", did not take long time. Can be used again case needed.

I used only the trailer winch and elbow grease to get here of the trailer and on to the "cradle". Fastened the stern with a rope and "dragged "the trailer away to keep it in position on the cradle when sliding down from the trailer. With one or two helping hand don't think rope is needed.

Would keep air in the tubes, guess the hull is stiffer that way?

I used to lift the 6.5m off with of 5t ratchet straps and a trolley jack under the planing pad.

Can you not use the winch and put it down on to some tyres? Pull the strap right out, around the axle and back up to the bow eye and winch away. If the rollers are OK you can drop it on to some tyres, it's easiest to have the trailer on the tow hitch if possible.

Thats the problem its the rollers , or their retaining washers that are the problem, I only just got it back on last time

Arr.... I hope thy Agric shed builder factored in a 6m RIB when designing the roof/support loading


Dont worry chaps It'll come off one way or t'other, just didnt want to crush the hull at a weak point at the sides , dont think theres that much weight in it anyway but it aint a new boat, and the glass might be a bit more brittle at the edges

Snow loading I think they call it.
