Thanks for the reply.
Still trying to get my head aropund this.
The wrench say's it is good for 625 ft/lbs.
So would that be:
(3.04 x 2.2)=6.69lb per 25.4x12=304.8ft :: 2,039.12lb/ft, making the wrench less that 1.3 of the required power ?
I have a manual brake winch with a 320mm handle that simply turns a shaft to operate the winch, either up or down.
The specifications state that 19kg of hand force is required to operate the winch(assume it refers to max load applied).
If i was to remove the handle and use an impact wrench...
