RopeDrumCount rope selection and drum planning for safe and smooth lifting. It calculates rope tension so you know the force the rope must handle. You can estimate breaking strength and check the safety factor to avoid risky choices. The app helps choose a suitable rope diameter and shows stretch or elongation under load. It also calculates rope weight per meter, which matters for long lifts and reeving. For drum design and setup, it calculates rope drum capacity and how many rope layers can fit. Fleet angle and bending ratio (D/d) are included to reduce wear and improve rope life. In short, it helps you pick the right rope and confirm the drum arrangement with clear numbers.
