Abstract
A crane having progressive function control preferably includes the crane, an electronic control device, a load sensor, a boom angle sensor, a boom length sensor, and a steering angle sensor. The load sensor measures a load on the crane boom. The boom angle sensor measures an angle of the crane boom. The boom length sensor measures a length of the crane boom. The steering angle sensor measures an angle of the rear wheel. The load sensor, boom angle sensor, boom length sensor and steering angle sensor are read by the electronic control device. The electronic control device receives inputs from a drive joy stick, a boom angle joy stick and a boom extension joy stick. The electronic control device includes a drive reduction algorithm and a boom reduction algorithm. The algorithms are used to retard inputs from the drive joy stick, boom angle joy stick and boom extension joy stick.
