What percent of tipping are most crawler crane's load charts based on?

Most crawler crane load charts are generally based on a tipping allowance of 75%. This percentage is a standard safety factor that accounts for dynamic conditions that may occur during lifting operations. Tipping refers to the crane's stability and involves calculations to ensure that the crane will not tip over while lifting a load.

The load chart provides critical information about the crane's capability under various conditions and emphasizes the importance of maintaining a safe working margin. By basing the load chart on a 75% tipping criteria, operators ensure there is an adequate buffer for safety, taking into account factors such as boom angle, the radius of the load, and the weight of the load itself. This practice helps prevent overloading the crane and minimizes the risk of accidents during operation.

In this context, other percentages, such as 50%, 80%, or 85%, would not accurately reflect the standard practices used in the industry for crawler cranes, as 75% strikes the right balance between safety and operational efficiency.
