A main boom is the central, primary lifting arm mounted on the machine's front or center, designed for heavy lifting and precise pipe positioning. A sideboom is a secondary, side-mounted attachment used primarily for stabilizing and guiding pipes during laying operations, with less lift capacity.
Perform visual inspections daily before use. Conduct thorough structural and functional inspections monthly, with non-destructive testing (e.g., magnetic particle or ultrasonic) annually or as per manufacturer guidelines (typically every 1,000-2,000 operating hours).
Minor cracks in non-critical areas may be repaired by qualified welders following OEM procedures and using approved materials, but major structural cracks or damage in high-stress zones often require boom replacement. Always consult engineering assessments and comply with safety standards.
