If a crane is modified and re-rated, who must check it thoroughly?

A certified inspector
An experienced operator
A qualified engineer
A maintenance technician

The correct answer is: A qualified engineer

In the context of modifying and re-rating a crane, it is essential that a qualified engineer conducts a thorough check. This is because a qualified engineer possesses the necessary knowledge and expertise to understand the structural integrity and operational parameters of the crane after modifications. They are trained to assess whether the modifications comply with safety standards and regulations, thereby ensuring that the crane can safely handle the specified load capacity. The engineer will evaluate the design, materials, and functionality of the modifications, which are critical to maintaining safety and efficiency in its operation. While other roles, such as a certified inspector or an experienced operator, play important parts in the overall safety and operational delivery of crane usage, only a qualified engineer can provide the technical assessment required for the adjustments made to a crane's structure and load rating. This level of scrutiny helps prevent failures that might arise from incompatibility or inadequacy in the modified components of the crane.
