I had a small block and tackle in the garage for years, and I was going to use for pulling my trike up onto the trailer when I do my Shetland trip - of course now I finally want to use it, I can't find it anywhere.

So I wnt hunting on Ebay and found this
http://www.ebay.co.uk/itm/Rope-block-and-tackle-pulley-cargo-hoist-180kg-lifting-lift-/280853921508?pt=UK_Lifting_Moving_Equipment&hash=item416432bee4 - which is very similar.

Just want an opinion - my trike weighs 340kg, and this gear is rated for lifting 180kg. But I don't want to lift the trike, just pull it up a ramp - do you reckon this will do the job?

Easily I'd have thought, as long as you attach it to something strong that won't bend under load

Yep, will have to look at that. I'm going to look at the trailer in a week or so when the owner is back from his hols, will discuss that with him, he will have loads of ideas as he's a long time bike owner/builder/trials rider etc and ex marine as well!

What is the angle of the ramp you are pulling it up ?

I had one like that years ago, mine was a Haltrac hoist, still around somewhere.
Seem to remember I used it once, for pulling a crashed rally car onto a trailer and lt worked OK, plus pulled many engines out of cars, heaviest was an old "Essex" 3 litre V6 from a Capri which felt like it weighed a ton.
Reckon it should work fine, but won't be too quick.
Only problem I see I'd is possibly the pulling distance, as it is not designed to pull things too far.
Lifting an engine out of a car is not a long pull.
You will have to open it out a fair way before you start and try to judge the distance you have opened i it out compared to how far you will need to pull the trike.
Still reckon it should be OK though.
It looks like 5 or 6 ropes between pulleys, so it will pull 5 or 6 times the distance of the gap between the pulleys on the pulling rope.
(Am I making any sense, as it's a bloody long time sinse I did physics at school?).
As Andy says the angle of the ramp is quite critical, obviously the gentler the better with the rope being a bit lightweight.
Andy will probably work out what strength rope you need to drag the weight up a particular slope, but I forgot those sort of calculations a long time ago. Not much friction involved as obviously on wheels!

Looks cheap. Dont like it. I'll see what we have kicking about in the buckshee store at work. I'd go for something rated higher. Always overestimate never underestimate.

Don't know about the angle of the ramp yet, but that can be adjusted if necessary by getting a longer ramp..

Oh and.............

Silly question and I may have missed something, but why can't the trike drive up the ramps (x 3 obviously) under its own power, if you are taking it on a holiday trip?

Bit dodgy putting on enough power to get it up the ramp and shutting it off quick enough not to go through the front of the trailer................

How about something like this if you can fix it to the trailer?
http://www.ebay.co.uk/itm/1200LB-HAND-WINCH-BOAT-MARINE-TRAILER-65FT-MANUAL-/320581554406?pt=UK_Lifting_Moving_Equipment&hash=item4aa42650e6

I use an electric winch like this to load my K1200R Sport onto a bike trailer. It's not the best quality and is quite noisy but it makes solo loading safer and easier. Again, you need to fix it to the trailer but that shouldn't be too difficult. A YTX14 bike battery provides the power; I just keep it topped up on the charger.
