Abstract:
Overhead lifts with control systems are disclosed. The overhead lifts may include a lift actuator communicatively coupled to a control system. The control system may include a control unit comprising a processor and a memory having computer readable and executable instructions and at least one port for communicatively coupling the control unit to at least one of a computer, a network, and a data storage device. The processor executes the computer readable and executable instructions to: determine at least one operating characteristic of the overhead lift and an operating time of the overhead lift as the overhead lift is actuated; determine an accumulated load-time parameter for the overhead lift based on the at least one operating characteristic and the operating time; and provide an indication that a component of the overhead lift requires service based on the comparison of the accumulated load-time parameter to a service constant.
