| MEASURING DIAMETERS OF WIRE ROPE |
 |
| REEL CAPACITY CALCULATION |
| The following formula is a genereal guide to establish the approximate length of rope that will fit onto a reel or drum. This formula is based on a uniform wind with the same quantity of wraps per layer. |
 |
The formula is : (A + D) x A x B
x K = L A = Depth of outside edge of the flange to the drum B = Width of drum between flanges D = Drum Diameter K = The constant for the rope diameter (see table below) L = The length of rope in feet |
| The formula below uses the following reel and wire
dimensions. A = 10",B = 20",D = 18", the wire rope diameter is 1/2" so K = 0.925 |
|
| would be
calculated as follows (10 + 18) x 10 x 20 x 0.925 = 5,180 ft. |
