The multiplier is the power factor. The multiplier is half that; (without considering the friction force of the pulley) it only needs 1/4 force for the 4 bearing capacity. Depending on the number of pulley and the way the wire rope is worn. What the elder brother said: "there are several strands of wire rope on the hook, and the ratio is just a few". The multiplier of the double pulley is equal to one half of the steel wire branch of the sling.
The crane is hoisted by wire ropes, pulleys and hooks, and the pulley of the hook moves up and down with the hook. This is the pulley. The hook has a pulley, half the force, the multiplier is 2; There are two, the multiplier is 2X2 is equal to 4... It is. In general, two strands of wire rope are needed on each pulley, and several strands of wire are on the hooks, and the ratio is a few.
The multiplier is that the lifting weight is a multiple of the force per share of the steel wire. Example: four tons of steel wire rope will be hoisted four tons, and each share of steel wire will only force one ton, and the multiplier is four.
