Abstract
Abstract An industrial truck has a hood normally seated on the mid portion of a frame. A counterweight has a first portion positioned adjacent a first portion of the hood and connected to the hood. A second portion of the counterweight is positioned adjacent and pivotally connected to the frame end portion for pivotal movement of the counterweight and the hood in unison and relative to the frame between a first position at which the hood is seated on the frame and a second position at which the hood is spaced from the frame. A fluid jack has first and second elements movable relative to each other with the first element being pivotally anchored to the frame end portion and the second element being pivotally connected to the counterweight. The fluid jack is of a construction sufficient for pivoting the counterweight and hood between the first and second positions.
