摘要： An industrial truck includes: a chassis, a mast pivotally mounted on the chassis, a lifting element for lifting a load, the lifting element being mounted on the mast in a slidable manner along the mast; a plurality of actuating units including: a lifting actuator configured to move the lifting element along the mast, a tilting actuator configured to tilt the mast with respect to the chassis, a wheel drive system for driving wheels of the industrial truck; a plurality of sensors including: a load sensor for detecting the load on the lifting element, a tilt angle sensor for detecting the tilt angle of the mast with respect to the chassis, and a height sensor for detecting the height of the lifting element with respect to the mast, a control unit configured to control the plurality of actuating units based on information detected by the plurality of sensors for achieving stability of the industrial truck during operation, wherein the control unit is configured to generate one or more control values by using a mathematical model of the industrial truck to which information detected by the plurality of sensors are inputted, the control unit being configured to control the plurality of actuating units based on the one or more control values. The industrial truck further comprises a rear axle load sensor configured to detect the load on a rear axle of the industrial truck, wherein the control unit is configured to control the operation of the industrial truck also based on a rear axle load value detected by the rear axle load sensor.

摘要： A dolly for indoor and outdoor use including a supporting frame extending along a main axis of extension and a loading platform mounted above said frame. The dolly also includes at least one steering and drive wheel coupled to the bottom of the frame and at least one pair of idle wheels coupled to the bottom of the frame and positioned symmetrically relative to the main axis of extension. The dolly also includes a control structure including a plurality of sensors configured for measuring a plurality of operating parameters of the dolly and for generating respective signals representing operating parameters and a processing unit configured to receive the representative signals and to impart a steering command to the at least one steering and drive wheel at least as a function of the representative signals.
