Abstract: Provided is a construction machine including an engine, a hydraulic pump with a supercharger, and a hydraulic actuator, being capable of attaining both of a quick rise of engine speed and an operation of the hydraulic actuator during the rise of the engine speed. The construction machine further includes a supercharging pressure detector to detect a supercharging pressure of the supercharger and a controller to control absorption torque of the hydraulic pump, namely, pump torque. Until engine speed of the engine reaches target engine speed, the controller calculates target pump torque from a predetermined relationship between engine no-load speed and the target pump torque, corrects the target pump torque so as to make it smaller as the detected supercharging pressure is lower, and limits actual pump torque to the corrected target pump torque, until engine speed reaches target engine speed from engine speed lower than the target engine speed.

Abstract: An industrial vehicle has a frame, a lift arm, a working Implement, a front link, a rear link and a lift cylinder. The lift arm has a front end. The working implement is mounted to the front end of the lift arm. The front link is pivotally connected at one end to the lift arm and at the other end to the frame at a first connecting position. The rear link is pivotally connected at one end to the lift arm and at the other end to the frame at a second connecting position. The lift cylinder is pivotally connected at one end to the lift arm and at the other end to the frame at a third connecting position. The first connecting position, the second connecting position and the third connecting position are located at substantially the same level.
