Can anybody tell me where to purchase rope pulleys to lift my tinnie off the
camp trailer into the garage roof when not required.
Yacht ones far too dear and the total weight is about 150kgs.
I have tried all the usual
places in
Melbourne.

Surely Bunnings have a range of pulleys suitable.

Why use pulleys at all.....some eye-bolts or screw eyes from bunnings etc may suffice. cheap pulleys are available in the same section there normally :-)

I just use a 4 legged sling attached to eyelets in the boat. Then use a chain block to lift the boat up onto a mezzanine floor in the shed. Works great and easy to manage on my own.
I also use the same chain block for the boat rack as
well as rolls of fenceing wire out of a trailer.

You say Yacht ones are too expensive.
Places like Bias Boating and Whitworths have a massive range of pulleys all different sizes and prices. Some are very expensive, but not all.
I just bought a couple from Bias for a home made crane that lifts my outboard from boat to bracket on caravan. About $9.00 each. Rated at 600 KG break load and 300 KG working load. Ronstan brand. Quit a few available below $20.
You say 9mm rope. I use Super Rope. 5mm is rated to 1,500 KG. Pretty expensive, but very good stuff.

For things like shackles, pulleys and the like, try the rigging specialists. Phone them up first before you go and tell them what you want. No affiliation, just hate getting ripped off by Bunnings.

Here is what you are after, the 9mm one (code 162027):

Bullivants should do courier to you as
well if they are not near you (about the price of fuel driving there yourself?)
or try:

Let us know how much they were, interested to hear how you go.

Thanks Norm C and Wazza
Just got my hands on a Whitworths catalogue and there are a few reasonable priced pulleys there. Tried Bullivants in Warragul rd but their stuff is a bit heavy,the bloke was very helpful. I was looking for the old rope type block and tackle we used to lift motors out with.
Thanks for your help

As another idea, we perform rescues using an extremely small and lightweight system, which we call the "haultrack" pulley system.
It consists of two Ronstan triple block pulleys (RF82 & RF343), one with a v-jam cleat, and 15m of 5-6mm "climbing cord". For around $100 this sytem has either a 6:1 or 7:1 hauling advantage (means your boat will take just over 20kg to lift), plus it takes up around 150mm (6 inches) when chock-a-block with over 2m reach when fully extended. Rated at over 500kg, it is more than adequate for most non-mechanical tasks. :-)
Ronstan RF82 - image close to actual size.
Ronstan RF343 - image close to actual size.
We left behind the old style heavy blocks years ago as their weight alone was limited some of the advantage.

:) Just realise that you will have to buy the components seperately and assemble it yourself.
There is also a trick with the reaving of the pulley system as you will find out, as you need to end up finishing the cordage at the becket. Give me a yell if you need help :-)
