Winch calculationEMCE

The effective drum radius used in this calculation is the distance between the centreline of the active rope layer and the centreline of the drum. For winches with only one layer of rope this is a constant factor. For winches with multiple layers the distance is a variable and depends on the amount of rope wound on the drum.

Apr 24 2017 · The larger pulley has then taken up 2πR of line from supporting the load. The smaller pulley has rotated in the same direction letting out 2πr of line to the load. So the load rises 2πR-2πr. The mechanical advantage is the distance pulled divided by the distance lifted or 2πR/(2πR-2πr) = R/(R-r). Note that if the radii differ by only 2

Differential pulleyWikipedia

A differential pulley also called "Weston differential pulley" sometimes "chain hoist" or colloquially "chain fall" is used to manually lift very heavy objects like car engines is operated by pulling upon the slack section of a continuous chain that wraps around pulleys. The relative size of two connected pulleys determines the maximum weight that can be lifted by hand.
