A control system for a liftcrane powered by a closed loop hydraulic system. In a liftcrane that includes controls by which an operator can run the liftcrane and mechanical subsystems each powered by a closed loop hydraulic system having a pump and an actuator, the present invention provides a controller responsive to the controls and connected to the mechanical subsystems, and further in which the controller is capable of running a routine for controlling said mechanical subsystems to define operation of the liftcrane.
