Abstract

1. Procedimento e dispositivo per impedire il ribaltamento di una gru o di un veicolo elevatore di salvataggio.2.1 Nei bloccaggi noti delle molle sui veicoli, normalmente prima dell'estrazione delle traverse di appoggio le escursioni elastiche degli assi vengono massimizzate tramite tensionamento a fune e vengono bloccate con cilindri idraulici. Valvole di bloccaggio a tenuta di pressione impediscono un cedimento di questa posizione di bloccaggio.2.2 L'invenzione sfrutta questo tipo di fissaggio delle molle affinché, nella successiva fase di appoggio, la pressione di reazione idraulica che si genera nel cilindro (6) di fissaggio delle molle e provocata dalla fase di appoggio venga utilizzata come grandezza di comando per la stabilità.3. Figura 2.1. Procedure and device to prevent the overturning of a crane or a rescue lifter. 2.1 In the known locking of the springs on the vehicles, normally before the extraction of the supporting crossbars, the elastic excursions of the axles are maximized by means of cable tension and they are locked with hydraulic cylinders. Pressure-tight locking valves prevent a failure of this locking position.2.2 The invention exploits this type of fixing of the springs so that, in the subsequent support phase, the hydraulic reaction pressure generated in the fixing cylinder (6) of the springs and caused by the support phase is used as a command variable for stability. 3. Figure 2.
