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.
