What is one of the key specifications for the strength of an elevator rope indicated on the rope tag?

The breaking load is a crucial specification for the strength of an elevator rope as indicated on the rope tag. This measurement represents the maximum amount of weight or force that the rope can withstand before failing. It is essential for ensuring the safety and reliability of the elevator system, as the breaking load must exceed the maximum anticipated load during operation, including any dynamic forces experienced during use.

Understanding the breaking load helps elevator technicians and engineers assess if the rope is suitable for the specific application and if it meets safety standards. This specification also plays a vital role in maintenance and inspections, where the condition of the rope is evaluated against its breaking load to determine if it needs replacement or other action to maintain safety.

The other specifications, such as thickness, weight, and number of strands, are important as well but do not directly convey the rope's ability to handle loads under operational conditions the way breaking load does.
