When cranes are working on rubber, they are typically rated at what percentage of tipping?

When cranes are working on rubber, they are typically rated at 75% of tipping. This percentage is significant because it accounts for the stability of the crane while ensuring safe operational limits. The rating reflects the maximum load that can be lifted without compromising the crane's balance and safety on rubber tires.

When cranes are used on firm ground or mats, they may be designed to handle a higher percentage because of the more stable support they receive. However, when operating on rubber, such as tires, there's a need to factor in the dynamic movement, potential for added stress, and reduced stability. Hence, 75% is a more conservative and safer threshold to prevent tipping, ensuring reliable operation while minimizing the risk of accidents.

This rating is established based on industry standards and safety protocols that consider various factors, including crane design, weight distribution, and ground conditions. Understanding this rating is crucial for operators as it impacts operational planning and safety measures when working with cranes on rubber surfaces.
