<p>The invention relates to a safety device for a self-propelled earthmoving appliance having a hydraulic transmission with a reverser and at least one stabilizer which can serve as a support for the said appliance. According to the invention, the safety device comprises control means (23, 24, 25, 26) connecting the stabilizer control lever functionally to the valve means (60) controlling the position of the reverser, the said control means being passive when the reverser is in the neutral position and active when the reverser is not in the neutral position, in order, in the latter case, to cause a return to the neutral position automatically. Consequently, the raising of the stabilizer or stabilizers can under no circumstances cause a movement of the machine if the control lever of the reverser is not in the neutral position. The invention is used for equipping appliances of the shovel-loader type having a pair of stabilizers mounted at the rear of the chassis.</p> |
