Block and Pulley setup

Chunks

Hi,

Firstly, mods please re-locate if deemed in wrong forum, and thanks in advance.

My project:

• I'm working on my motorbike at home in the garage.
• The weight of my motorbike is 180kg (unladen).
• I want to remove the wheels and front fork of the bike.
• To do this I need to raise the bike off the floor about a half a metre (possibly a metre).
• I want to suspend it from the rafters of the bricks and mortar shed.
• I've checked the load capacity of the rafters and they would be easily able to take the weight of the bike when spread across 2 (1 would do it, but 2 to play it safe).
• I want to rig up a block and pulley system so I can put a seat under the bike using a piece of wood and have it set up like a cradle.
• This would be attached to a rope and would then be hoisted to raise the bike to the relevant height.
• I can then secure the bike from moving around using ratchets attached to the wall etc..

What I'm looking for help / input / advice on is the pulley system. I'm not too familiar with the best way to set it up and number of blocks required, pulling force required etc...

Am open to setup suggestions by those of you who would use them regularly enough for sails and maintenance etc..

Thanks.

What type of bike is it?

I have taken the forks and front wheel from my BMW K1100LT (weighs a bit more than yours - 290KG), without any need for raising the bike. Once the wheel comes off, the forks have enough clearance to come out of the yokes while the bike is on the center stand.

What I do is put a plank/ladder over the rafters, and attach a strong rachet strap from the yoke/frame to it. I then (after listening the wheel axel) ratchet up the front of the bike so it is resting on the center stand/back wheel. I then put something under the engine to support it, just in case. The wheel comes off, followed by the forks. No problem.


Sorry, I just noticed you said wheels (plural). What I would then do is keep the support on the engine, but have it just lower than the ratchet. I would then leave the ratchet off, settling the bike on the centre stand and support. Possibly use some side supports, and remove the back wheel.

I would be slow to have the bike suspended for any length of time from the rafters. Too much chance of something failing and bringing the bike, and roof down around my head.

It's an SV650. The plan going forward would also to have it suspended so I can do en engine removal etc... also so ideally I'd like to have the option to have it completely off the floor.

I have a few blocks that I'd use underneath it when suspended to take some of the load.

I was thinking about the ratchet strap idea and it seems pretty straightforward... until you get to lowering the thing back down.. Then I'd be in danger territory... unless there's a way of letting the ratchets out easily..?

I would use a chain block personally for a job like this. 1 ton would be plenty.
