What is the recommended limit for capacities when a crane is on rubber?

When operating a crane on rubber, it is crucial to ensure the safety and stability of the equipment. The recommended limit for capacities is set at 75%. This guideline is established to account for various factors affecting the crane's stability when it is operating on a mobile surface, such as tires on rubber, which can result in a higher possibility of tipping or instability compared to a crane that is set on a more stable foundation, like outriggers or a solid ground.

Staying within this capacity limit helps maintain a safety margin to prevent accidents that could occur due to overloading. It ensures that the crane operates within a range that can accommodate potential shifts in weight distribution and dynamic loads that occur while lifting or moving materials. This understanding is vital for any operator to guarantee safe practice and effective operation.
