An increase by more than 10% in the rated speed or capacity of the load carrying unit is classified as what?

An increase by more than 10% in the rated speed or capacity of the load-carrying unit is classified as a major alteration because it significantly changes the operational characteristics and performance of the elevating device. Major alterations require extensive evaluation, re-certification, and possibly re-engineering to ensure safety and compliance with regulatory standards. This type of modification can affect the structural integrity, operational limits, and safety systems of the equipment, necessitating a thorough review by qualified professionals to mitigate any risks associated with the change.

In contrast, minor alterations typically involve adjustments or changes that do not significantly impact safety or performance. Routine maintenance consists of regular checks and servicing that ensure the device operates within its original specifications. Compliance issues would relate to failures to meet existing regulations or standards but do not inherently imply a change in capacity or speed. Therefore, the classification as a major alteration underscores the importance of maintaining strict standards when making significant adjustments to elevating devices.
