Method of operating a fork-lift truck 1 comprising the steps to; determine a hydraulic pressure signal P by means of the at least one detection device 2, wherein the hydraulic pressure signal P corresponds to an hydraulic pressure in, at least a section, of an hydraulic system of a fork-lift truck 1, transfer said hydraulic pressure signal P to an electronic load carrier unit; determine by means of the electronic load carrier unit whether the hydraulic pressure signal P adopts a value, within a predetermined value range Pval;determine by means of the electronic load carrier unit if a load carrier of the forklift truck is, at least partially, supported by an external object not being part of the forklift truck or a fixed internal object of the fork-lift truck, based on the determination whether the hydraulic pressure signal is within the predetermined value range Pval. The invention also relates to a computer program product and a fork-lift truck that can perform the method. |
