Abstract (en)
A lifting vehicle (1) comprises a mobile lifting arm (3), first measuring means (16) for measuring at least one working parameter of the arm (3) and a control device (13) receiving an input signal (SJ) and configured for deriving the value of the natural frequency of vibration of the arm (3) as a function of the load and of the working range and for determining a control signal (SV) for actuating the arm (3). In particular, the signal (SV) is defined at least partially by the convolution of the input signal (SJ) with a plurality of pulses having a time delay between one another and an amplitude defined as a function at least of the first natural frequency.
