What is the minimum diameter allowable for hoist ropes on a personnel hoist?

The minimum diameter for hoist ropes used on personnel hoists is based on safety standards and structural integrity required for lifting capacities. A diameter of 13 mm is specified as the minimum to ensure that the ropes can safely support the weight of personnel and withstand dynamic loads, wear, and environmental factors. This dimension is established through safety regulations, which consider factors like rope strength, flexibility, and resilience.

Choosing a diameter that is too small could lead to premature wear and potential failure of the rope, jeopardizing safety. Therefore, the standardization of 13 mm helps ensure that personnel hoists operate within safe limits, providing necessary strength and ensuring reliable performance over time.
