HIGH-TEMPERATURE EFFECT ON OPERATION RISK OF LIFT CABLES
As a result of the steel cable security rating, it is essential to determine that the nature, value, and quantity of defects will not exceed the critical reject limits while in operation. The high-temperature impact results in uneven wire heating in the cable operation activity. It leads to the cabl...

| description | As a result of the steel cable security rating, it is essential to determine that the nature, value, and quantity of defects will not exceed the critical reject limits while in operation. The high-temperature impact results in uneven wire heating in the cable operation activity. It leads to the cable deflected mode change, and, consequently, the accident risk grows. On the increase of heating temperature to 370 °С, steel cables need to be rejected, even without waviness in them. The risk of rope break is dramatized by the fact that the steel cable technology, including those with the mechanical core, admits irregularities (various strand length). While in operation, short strands are overloaded, and the long ones are underloaded which results in the waviness origination. For higher safety of the lift cables under the high-temperature conditions (at temperatures above 370 °С), the algorithm considering the degradation risk in the steel cable, and special cable structures with indicator wires are offered for application. |
