For a residential platform lift, the governor shall set at a maximum speed of __________.

For a residential platform lift, the maximum speed setting for the governor is specified as 75 feet per minute (fpm). This speed limit is established to ensure the safety and usability of the lift within residential settings, where users may include individuals with mobility challenges.

A governor is a crucial safety device that monitors the speed of the lift and will activate in the event that the lift exceeds this designated speed, preventing potentially dangerous situations such as free-fall or uncontrolled descent. Setting this speed at 75 fpm strikes a balance between efficient operation and safety for users, allowing them to ascend or descend at a manageable pace.

In residential installations, where the focus is on accommodating the needs of individuals, 75 fpm is considered an optimal and safe operating speed. The other options, while representing plausible speeds, exceed the established limit for residential platform lifts and would not meet the safety standards necessary for this application.
