What category of safety devices affects the safe load lifting and handling capabilities of equipment?

Operational safety devices are specifically designed to monitor and enhance the safe load lifting and handling capabilities of equipment. These devices include features such as load limiters, pressure sensors, and other mechanisms that ensure that the crane operates within its specified limits. By doing so, they actively prevent the equipment from exceeding its safe load capacity, which is critical for ensuring the safety of both the operators and surrounding personnel.

Emergency safety devices, while important for addressing sudden failures or hazardous conditions, do not have a direct role in the day-to-day lifting and handling operations. General safety devices may include a range of equipment that promotes overall safety, but they are not specifically targeted at load management. Preventive safety devices may refer to systems that help avoid accidents, yet they typically do not focus specifically on lifting capabilities in the same manner as operational devices.
