Post-Assembly Inspections
Before the equipment can be used, it must be inspected by a qualified person to ensure it is configured in accord with manufacturer equipment criteria.
The qualified person may be the A/D director. Where manufacturer equipment criteria are unavailable, a qualified person must:
- Determine if a registered professional engineer (RPE) familiar with the type of equipment involved is needed to develop criteria for the equipment configuration (If an RPE is not needed, the employer must ensure the criteria are developed by a qualified person; if an RPE is needed, the employer must ensure they are developed by an RPE).
- Determine if the equipment meets these criteria before the equipment is used.
Pre- and Post-Erection Inspection of Tower Cranes
Prior to being erected, tower crane components must be inspected for damage or excessive wear by a qualified person. The qualified person must pay particular attention to components difficult to inspect thoroughly during shift inspections.
If a qualified person determines a component is damaged or worn to the extent it would create a safety hazard if used on the crane, the component must not be erected on the crane. If the damaged or worn component is repaired and, upon re-inspection by a qualified person, is no longer a safety hazard, the component may be erected on the crane. If the qualified person determines, though not presently a safety hazard, the component needs to be monitored, the employer must ensure the component is checked in the monthly inspections. Any such determination must be documented, and the documentation must be available to any individual who conducts a monthly inspection.
In addition to the other requirements listed above for post-assembly inspections, the following requirements must be met:
- A load test using certified weights, or scaled weights using a certified scale with a current certificate of calibration, must be conducted after each erection.
- A load test must be conducted in accord with the manufacturer's instructions when available. Where these instructions are unavailable, the test must be conducted in accord with written load test procedures developed by a registered professional engineer familiar with the type of equipment involved.
