Lift control systems for lifting devices and lifting devices comprising the same

A lifting device for raising and lowering a payload coupled to the lifting device, the lifting device comprising:

• a lift mast mechanically coupled to a base at a first end of the lift mast, wherein the base comprises a pair of base legs pivotally attached to a cross support such that the pair of base legs are pivotable with respect to the lift mast;
• a lift arm pivotally coupled to the lift mast at a second end of the lift mast;
• a lift actuator mechanically coupled to the lift mast and the lift arm, wherein actuation of the lift actuator raises or lowers the lift arm relative to the base;
• a base actuator mechanically coupled to the base legs, wherein actuation of the base actuator pivots the base legs with respect to the lift mast;
• a lift control system communicatively coupled to the lift actuator and the base actuator, the lift control system comprising:
• a control unit comprising a processor and a memory having computer readable and executable instructions, wherein the processor executes the computer readable and executable instructions to:
• determine at least one 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 at least one operating characteristic and the operating time;
• compare the accumulated load-time parameter to a service constant;
• and
• provide an indication that a lift structural component or a lift electrical component requires service based on the comparison of the accumulated load-time parameter to the service constant.

A method for operating a lifting device comprising a lift actuator for raising and lowering a load coupled to the lifting device, the method comprising:

• determining an operating characteristic of the lift actuator as the lift actuator is actuated;
• determining an operating time of the lift actuator as the lift actuator is actuated;
• determining an accumulated load-time parameter for the lift actuator based on the operating characteristic and the operating time;
• comparing the accumulated load-time parameter to a service constant indicative of a structural component requiring service;
• and
• activating an indicator when the accumulated load-time parameter is greater than the service constant.
