Can lifts be modified without permission from the manufacturer?

Modifications to lifts must be approved by the manufacturer because altering the original design can compromise safety and functionality. The manufacturer has specific knowledge about the lift's engineering and safety features, ensuring that any changes do not pose hazards to operators or passengers. Such approval typically involves written permission, ensuring that the modifications are safe and compliant with industry standards. This requirement is put in place to uphold safety regulations and maintain the operational integrity of the equipment.

The other options might imply that modifications could be made under certain situations, but this could lead to unsafe practices, as unauthorized changes might not adhere to relevant safety codes or standards. Therefore, the necessity for written permission is a critical aspect of maintaining safety and accountability in lift modifications.
