Abstract
A crane control system and method which automatically de-rates the maximum capacity of the crane when the boom is located in a first zone located on one side of the truck or in a second zone located on the opposite side of the truck. The control system de-rates the crane without input from the crane operator. The control system may use an inductive proximity sensor located on the base of the boom to locate stationary steel targets located around the base of the boom. The targets approximate the outer ranges of the first and second zones.
