To calculate the load capacity of a single-rope lift, you need to consider several factors including the strength of the rope, the diameter of the rope, the angle of the lift, and the safety factor. The basic formula involves determining the maximum load the rope can bear based on its material properties and construction, which is then adjusted by the safety factor to account for dynamic loads and potential wear. The formula might look something like this: Load Capacity = (Tensile Strength of Rope 脳 Area of Rope Cross-Section 脳 Safety Factor) / (Cosine of Angle of Incline). It's important to consult with engineering standards and the lift manufacturer's specifications for precise calculations.
