Hi PA - just wondering if you read post 18? here is part of it:-
It should be noted that these kilogram values do not mean you will get exactly that result if you were to set the drag on reel to that pull pressure. There is a thing called "static load" and "dynamic load".
These hooks are tested with static load ie gradually applied load where a dynamic load is suddenly applied ie a bucket weighing say 10kg if dropped a short distance will have an equivalent static load of more than 20kg at impact.
Of course the stretch of line and flex of rod will compensate for sudden impact loading to some extent.
A rough guide to sudden impact versus gradual load would be about 2 to 1 or 2.5 to 1. That is if the test showed 20kg to "failure" I would pretty safely expect to get my drag to work okay and the hook to stay in shape at 20/2=10kg or 20/2.5=8kg. When we design a crane for lifting weights we use a safety factor of 3 but that is a bit more about life and death than here running a load closer to failure as long as it is "fit for purpose".
The weights used were a combination in the bucket of lead, pavers and water and each load applied was rechecked and verified for accuracy. Max "static load" I could achieve was 65kg which should equate to just over 30kg of drag pressure.
Hope you find the tests and comments above useful and informative.
