[quote=gahamby]That's all very impressive. The gin pole picks up the lift line so instead of pulling straight down the mast you have a usable angle to lift or lower the mast. I do the same thing with a tall mast support. How many people do you imagine can or will go through all the above calculations before they come up with a mast raising rig? From an engineering standpoint it's the right thing to do. Instead of all that calculation show us what the load is at the mast attachment, the turn at the gin pole, the turning block and winch for the 45' mast you raised.[/quote]
