Abstract
A theatrical lift including a timer and an indicator light. The light indicates a need for maintenance after a predetermined amount of time passes as measured by the timer. Also, a lift, such as a theatrical lift, including an indicator, a reset switch and an indicator housing. The indicator is located on the indicator housing. The reset switch is located inside of the indicator housing. The indicator housing can be opened or partially opened to allow selective access to the reset switch. In this way, the reset switch can be easily reset by a lift maintenance technician as part of performing routine maintenance on the lift, but will not be easily reset by a lift operator as a casual matter.
