Red Seal Mobile Crane Operator Practice Exam

The overload protection system is designed specifically to prevent a crane from lifting beyond its rated capacity. This system continually monitors the load weight and the position of the crane's boom. If the load exceeds the predefined limits, the system activates, triggering alarms or engaging automatic safety measures to halt operation. This ensures the crane operates within safe parameters, protecting the equipment, personnel, and surrounding environment from the dangers of overloading.

Other systems, such as the alert system or weight distribution mechanisms, may contribute to overall crane safety and stability, but they do not specifically prevent overload scenarios. The engine throttle control impacts the crane's operational speed but does not influence the lifting capacity directly. The primary function of the overload protection system is crucial in maintaining safe lifting practices by actively monitoring and managing the load weight during operations.
