What is the use temperature of crane rigging?

There are many types of crane rigging. In order to ensure the safety of use, each crane rigging has a temperature range, and the sling should not exceed 400 °C.


When using the crane rigging in a high temperature environment, the load should be appropriately reduced to ensure the safety of use. When the temperature is between -40 °C and 200 °C, the new load of the crane rigging and its connecting parts is 100% of the original rated load. When the temperature is between 200 °C and 300 °C, the new load of the crane rigging and its connecting parts is 90% of the original rated load. When the temperature is between 300 °C and 400 °C, the new load of the crane rigging and its connecting parts is 75% of the original rated load. It is not allowed to use when the temperature is above 400 °C.


When using, check the working condition of each moving part. If there is no card rope or rope after the crane rigging is stressed, the weight will be stuck when lifting.
