Beginners guide to rigging.......

Basics but important

Keeping a sling or timber hitch nr above gob / cut on chogging down etc via block

so less travel for momentum to build on snatching keeping it controlled with less swing

also helps groundie/kit.

Thats not actually true, its the distance the centre of gravity ( COG) of the piece you are cutting is away from the block that that defines the amount of travel.

 

As long as you tie on between the gob and the COG then its irrelavant where you tie, as long as its not beyond the COG.

 

In fact, if you tie on as high as possible (still below the COG) then the groundie can pull in more slack as the piece goes over and that will reduce the amount of travel. GRCS works well for this.

Good stuff!!!

 

Thats really interesting and makes a lot of sense

Your right simon it is a 3:1 you count the legs at the moving blocks and i count 3...

 

I got to look again now!

I was going to write similar Rupe. You put it a lot more eloquently than me though.

 

Do you just pretension the GRCS to take any excess stretch out or do you keep cranking as it goes over?

that diagram was a 2-1

that diagram was a 2-1

 

No, its 3-1.

you count the legs of line (rope) mate, there are 2 pulleys which create a 3 legs at the moving block there for making it 3:1.....

 

 

Great post Rupe and very accurate......

[Tony Croft aka hamadryad]

but you dont count the leg you pull? surely that is your 1 and the others are the 2-1
