Abstract

According to embodiments, a method for operating a lifting device monitoring with a control unit, monitoring current supplied to the lift actuator when the lift actuator is actuated; discontinuing the current supplied to the lift actuator when the current exceeds a current threshold value; determining an accumulated number of overload stops based on the current supplied to the lift actuator; determining at least one operating characteristic of the lifting device and an operating time of the lifting device as the lifting device is actuated; determining an accumulated load-time parameter for the lifting device based on the at least one operating characteristic and the operating time; and uploading, with a transceiver, at least one of the accumulated number of overload stops and the accumulated load-time parameter to at least one of the computer, the network, and the data storage device.
