What must be present in the cab of the crane at all times?

The requirement for having an operator manual and a load-rating plate present in the cab of the crane at all times is crucial for the safe and efficient operation of the equipment.

The operator manual provides essential information about the crane's operation, safety protocols, and maintenance guidelines. It serves as a reference for the operator to ensure that they are following correct procedures during lifting operations, which directly impacts safety on the job site.

The load-rating plate, on the other hand, specifies the maximum load capacity for the crane and important configurations for its safe use. This information is vital for preventing overloading, which can lead to accidents, equipment failure, and potential harm to personnel nearby.

Having both these items readily available in the crane cab is a standard safety practice, as it ensures that operators can quickly access critical information to make informed decisions.

In contrast, personal belongings, advertising materials, and tool sets do not serve this operational safety purpose in the same way, making them less essential to have in the cab while operating the crane.
