  • There are recommended groove diameters-to-cable diameter ratios for each cable construction. Most flexible cables, such as a 7×49 construction suggest a 15x ratio to maximize life. As stranding constructions simplify, the ratios increase. For instance, 7×19 wire rope has a 25x ratio, while 7×7 cables have a 40x ratio.

  • To determine the extension of fatigue life for a 3/4” wire rope using a 22.5” diameter sheave versus a 12” diameter sheave: Ratio B = 22.5” (sheave diameter) 3/4” (wire rope diameter) = 30 Ratio B = 12” (sheave diameter) 3/4” (wire rope diameter) = 16

  • Styles 2-4, 6, and 7. Mount these pulleys to a flat surface to assist with horizontal pulling or to guide a rope. Pulleys with two grooves are for use where multiple pulleys move a single load, such as block and tackle systems. They require about half the force of a single-groove pulley to move the same load.

    Generally, the wire rope-to-sheave size ratio should be 12:1 in order to hold the wire properly while under load. Know your numbers. Because a snatchblock can cut the direct pull load in half, choose a rigging pulley that has a rating of double the pull of the winch you"ll be using with it.

  • 2021/3/24 · In my case the rope will not see loads greater than 300lbs. Rope will probably be 3/16ths or 1/4 inch diameter. 5" and 6"-ish pulleys are recommended; I’d prefer to use 4".

  • The recommended clearances are 1.5 mm up to rope diameter of 28 mm and 3 mm for rope diameter above 28 mm. The groove diameter of the pulley or sheave should always be larger then actual diameter of the rope. But if the groove diameter is too large the rope will tend to flatten and if it is too small pinching or rope will take place.
