What type of alteration is typically required for the addition of advanced safety features?

The addition of advanced safety features generally constitutes a major alteration because it significantly impacts the functionality and safety of the elevating device. Major alterations often involve extensive modifications that can include changes to electrical systems, structural components, or safety mechanisms, which may require new design approvals, inspections, and possibly updates to compliance with current safety standards and regulations. This level of alteration is not just an update but often involves a comprehensive assessment to ensure the overall safety and operability of the device.

Minor alterations, in contrast, typically involve less significant changes that do not greatly affect the overall operation or safety protocols of the machinery. These could include cosmetic updates or non-structural changes that maintain the same safety standards. Improvement alterations might imply enhancements to existing components but do not necessarily require as extensive a review process.

The distinction lies in the extent and impact of the changes ultimately required to meet the newly implemented safety features.
