Abstract
A programmable control system for a crane that senses a hydraulic pressure of the lift mechanism, and controls the movements of the crane apparatus as a function of the magnitude of the hydraulic pressure. As the status conditions of the crane change, sense switches relay such information to a programmable controller and error codes are generated and presented to the operator. The control system can respond to the states of the sense switches and override wireless command inputs to the control system.
