According to ASME B30.3, who should recommend a preventative maintenance program?

The correct answer is that the crane manufacturer should recommend a preventative maintenance program. The reason for this is that the manufacturer has specific knowledge about the design and operation of their equipment, including critical components and recommended practices for maintenance. They possess expertise based on the engineering principles that govern the crane's operation and longevity.

By providing tailored maintenance guidelines, the manufacturer helps ensure the crane operates safely and efficiently throughout its service life, reducing the risk of breakdowns or accidents caused by inadequate maintenance. While operators, inspection agencies, and site supervisors play important roles in the overall management and operation of the equipment, they rely on the manufacturer’s specifications to develop or implement effective preventive maintenance practices. Subsequently, the manufacturer’s recommendations serve as a foundation for maintaining the equipment in compliance with safety standards and operational efficiency.
