What should be monitored during a crane operation to ensure safety and effectiveness?

Monitoring load weight and crane stability during crane operation is crucial for ensuring both safety and effectiveness. The load weight must be kept within the crane's rated capacity to prevent overloading, which can lead to mechanical failure or tipping. This involves checking the load's weight before lifting and continuously monitoring it during the operation.

Crane stability is also essential, as various factors such as ground conditions, load position, and dynamic forces during lifting can affect the crane's ability to remain upright. By monitoring the stability, operators can make informed decisions, adjust their lifting strategies, and apply counterbalancing measures as needed.

In contrast, focusing exclusively on weather conditions, operator skill level, or equipment age does not provide a comprehensive approach to crane safety. While these factors are important, they do not directly address the immediate operational risks associated with the load being lifted and the conditions under which the crane is operating. Therefore, assessing both load weight and crane stability is vital to maintaining a safe working environment on a job site.
