Abstract:
An industrial truck having at least one hydraulic mast lift cylinder, which is connected to a hydraulic block via a hydraulic arrangement that limits a lowering speed of the mast lift cylinder. The hydraulic arrangement is formed to limit the lowering speed in a load-dependent manner to at least two maximum values. A first maximum value is given for the lowering speed at the nominal load while a second maximum value is given for the lowering speed with a load that is smaller than the nominal load, i.e., wherein the first maximum value is less than the second maximum value.
