Counterbalanced forklift truck, has control device cooperating with rolling drive, working drive and steering lock drive such that device executes correction intervention maintaining or increasing stability against tilting of truck

摘要

The truck has a sensor (S) to capture and transmit a physical variable to a control device (SE). The device uses specific data of truck stored on a calculation model (D). The device cooperates with a rolling drive, a working drive and a steering lock drive such that the device executes a correction intervention maintaining or increasing the stability against tilting of truck according to moving and loading state of truck. The physical variable comprises of lifting load, lifting height, lifting torque, inclination angle of mast, steering lock angle of steering axle, displacement direction, displacement speed, longitudinal acceleration and transversal acceleration and rate of yaw of the truck.
