For each crane, where are guidelines and instructions for installing various boom attachments and components found?

The correct option is the manufacturer’s handbook. This document serves as a comprehensive source of information specific to the crane being used, including guidelines and instructions for installing various boom attachments and components. It provides detailed specifications and installation procedures, ensuring that users follow the correct processes as intended by the manufacturer.

The operator's safety manual, while important for outlining safety procedures and operational guidelines, does not typically contain in-depth installation instructions for attachments. Instead, it focuses more on safety practices while operating the crane.

The maintenance log is primarily used for recording maintenance activities and tracking the maintenance history of the crane, rather than providing installation instructions.

The safety protocols document encompasses safety measures but may not include specific technical details regarding the installation of boom attachments and components. Therefore, the manufacturer’s handbook is the most relevant resource for this purpose.
