How calculate how many turns of cable you will need on drum for cage and skip to move up and down by 500m
You must know the diameter of the drum. If it is d meters, then you will need
500 / πd
turns
Yes
If the winch drum has a diameter of 6cm,calculate how far the cage will drop for each single rotation of the drum.use the formula:c=2πr
Please help me

To calculate the number of turns of cable needed on a drum for a cage or skip to move up and down by a certain distance, you need to know the following information:
1. Diameter of the drum (D): Measure the diameter (in meters) of the drum on which the cable is wound.
2. Diameter of the cable (d): Measure the diameter (in meters) of the cable itself.
3. Length of cable required for one complete turn: This is equal to the circumference of the drum, which can be calculated using the formula: circumference = π * D.
4. Total distance to be traveled by the cage or skip (T): In this case, it is 500 meters.
To calculate the number of turns, you can use the formula:
Number of turns = T / (circumference + d)
Let's break it down with an example:
Suppose the drum diameter (D) is 2 meters and the cable diameter (d) is 0.1 meters. This gives us a circumference of the drum:
Circumference = π * D = 3.14 * 2 = 6.28 meters
Using the formula, we can calculate the number of turns:
Number of turns = 500 / (6.28 + 0.1) ≈ 500 / 6.38 ≈ 78.31 turns
Therefore, you would need approximately 78 turns of cable on the drum for the cage or skip to move up and down by 500 meters.
Please note that this calculation assumes that the cable wraps tightly and neatly on the drum without any overlapping or gaps.
