Abstract: A forward-control counterweight fork-lift truck has a liftable and tiltable load-lifting device (1), a traction drive and operating drives for the movement of the load-lifting device (1). A calculation model (D) is stored in a control device (SE), to which directly or indirectly acting sensors (S) are connected for detecting the lifting load (L), the lifting height (H), the tilting angle (WM), the load torque (M), the direction of travel (R), the driving speed (V), and the steering angle (WL). The control device (SE) is designed to determine a driving and load state (Z) based on the detected physical variables (L, H, WM, M, R, V, WL) and the stored calculation model (D) and is operatively connected to the traction drive and the operating drives. Depending on the driving and load state (Z) determined, the operating speed, starting and braking acceleration, and driving speed are each reduced.

Abstract: A forward-control counterweight fork-lift truck has a liftable and tiltable load-lifting device (1), a traction drive, operating drives, and a steering drive. A calculation model (D) based on vehicle-specific information is stored in a control device (SE). A plurality of sensors (S) detect physical variables (V, R, H, M, L, WM, WL, BL, BQ, G) relevant to the tipping behavior of the industrial truck. The control device (SE) determines a driving and load state (Z) based on the detected physical variables (V, R, H, M, L, WM, WL, BL, BQ, G) and the stored calculation model (D) and is operatively connected to the traction drive, the operating drives, and the steering drive such that, depending on the driving and load state (Z) determined, corrective interventions (K1, K2) which maintain or increase the tipping stability can be carried out.
