Embodiments of a personnel basket for attachment to a crane boom include folding sidewall sections; a rear wall connected to the sidewall sections; a front wall in pivotal connection to one of the folding sidewall sections; a floor in pivotal relation to the rear wall; a stalk integral to the rear wall and including a boom connection; and a cam or stop that transmits floor loads to the stalk. Because of the pivotal relationships, the personnel basket is moveable or foldable in a connected or assembled condition between a deployed (unfolded) state and a folded (fully collapsed) state. When in the deployed and folded states, the walls and floor remain connected to the personnel basket, the walls sharing a same orientation, the floor pivoting toward and away from the rear wall between a horizontal and vertical orientation.

Foldable personnel basket for a crane

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.
