Abstract
In an embodiment, a crane including a hoisting (i.e., load-lifting) mechanism is provided with a variable-speed load-dependent control system and method for operating functions of the crane. An exemplary control system includes an actuator subsystem for performing at least one function of the crane, a sensor for detecting the magnitude of the load lifted by the hoisting mechanism and a controller that communicates with the sensor, wherein, relative to a load signal from the sensor, the controller transmits a speed signal to vary an operating speed of at least one actuator of the actuator subsystem.
