Slowbee Posted August 29, 2011 Share Nope - to pully number 3. It's got a rope-securing nobbin in front of the pully itself (you can see it on the bottom end of the pic) That's the exact reason that I stipulated that type of pully instead of a normal one. Makes it far neater, and it's secure. It's pulling against itself, which also makes it easier to hoist uuummmm can you draw for us da picta ? like Mr Zaskar ?

Zaskar09 Posted August 29, 2011 Share uuummmm can you draw for us da picta ? like Mr Zaskar ? The rope end at point A just goes back to the pulley attached to the ceiling (closest to A). . . if I'm understanding Cpt correctly Link to comment Share on other sites More sharing options...
Captain Fastbastard Mayhem Posted August 29, 2011 Share Zaskar - that's using more pullies and rope than you need to... this is my proposal. the one end of the rope ties to the eyelet at the bottom of the right hand side pully. LHS pully is a 2-wheel variety. Easiest option, and no wastage of rope. You can tie off the other end on the bike itself, so the whole thing takes up less space than the bike itself...

Captain Fastbastard Mayhem Posted August 29, 2011 Share more simplistic, with directionality and anchor points to show where/how to secure it...# Link to comment Share on other sites More sharing options...
Zaskar09 Posted August 29, 2011 Share I totally agree, that would work. The more pulleys you add however (though more costly) the easier it is to hoist. Not knowing Chubba or his missus, raising the bike to the ceiling and then tying the rope to the bike itself might be a bit high. Might just be me, I'm a shorty. But your right, yours would be cheaper. Link to comment Share on other sites More sharing options...

But your right, yours would be cheaper. Ja, with 2 rollers each side (the LHS effectively has 2 rollers due to the tie-off on the bottom of the pully) the load is effectively halved. So for a 14kg bike, your wife would be lifting 7kg. Link to comment Share on other sites More sharing options...

Zaskar09 Posted August 29, 2011 Share Turns out the pulleys are a bit more expensive than I thought and I couldn't find any suitable hooks for under R60 a piece (went to 4 different stores). Maybe you guys have more luck with the pulleys at the coast, I don't know of any sailing stores in PTA. But I've figured out a way to build it for under R100. I'll build and test it tonight and then post pictures. Link to comment Share on other sites More sharing options...

MTBmofo Posted August 29, 2011 Share Un-rated carabiners bought at a hardware store cost about R10, more than strong enough. Is it not possilbe to bang two pulleys into the roof and and run two independant lines from the bike up to pulley and down to tie-off point? THe weight of the bike is shared between each pulley, no mechanical advantage, but it will work. Cheap and easy! Link to comment Share on other sites More sharing options...
