Abstract:
A control system for a lifting device and a lifting device comprising the same are disclosed. The control system includes a control unit comprising a processor with a memory communicatively coupled to the processor and having computer readable and executable instructions. A battery is electrically coupled to the control unit in addition to at least one indicator. The processor executes the computer readable and executable instructions to: determine an operating characteristic of the lifting device and an operating time of the lifting device as the lifting device is actuated; determine an accumulated load-time parameter for the lifting device based on the operating characteristic and the operating time; store the accumulated load-time parameter in the memory of the lift control system; compare the accumulated load-time parameter to a service constant; and provide an indication the indicator that a lift structural component requires service based on the comparison.
