What percentage of the maximum permissible load should the hoist wire rope be wound when installing on a tower crane?

When installing the hoist wire rope on a tower crane, it's recommended that the rope be wound to a percentage of the maximum permissible load to ensure proper functioning and safety. Winding the rope to 10% of the maximum permissible load allows for adequate clearance to prevent any risk of the rope tangling or compromising its integrity during operation. This percentage also aids in ensuring that the crane operates efficiently, maintaining a balance between load handling and safety margins.

A lower percentage, such as 5%, may not provide sufficient operating performance or risk mitigation. Higher percentages like 15% or 20% could lead to unnecessary stress on the hoist mechanism and compromise both safety and operational efficiency. The 10% standard aligns with safety guidelines in the industry, promoting a safer working environment while also ensuring that the equipment functions as intended.
