Crane having a toolless removable battery and progressive function control

A crane having progressive function control comprising:

• a crane including at least three wheels and a crane boom, the crane boom is pivotally retained on the crane;
• an electronic control device including a boom reduction algorithm;
• a load sensor, a boom angle sensor and a boom length sensor are connected to said electronic control device;
• and
• a boom angle joy stick is connected to said electronic control device, said boom reduction algorithm receives input from said load sensor, said boom angle sensor and said boom length sensor, said boom reduction algorithm provides a boom reduction factor, said boom reduction factor reduces a maximum travel value of the crane, wherein a drive speed, acceleration or deceleration requested by said boom angle joy stick is retarded by said boom reduction algorithm, if the motion requested by said boom angle joy stick is greater than a maximum travel value.
