TRACKED VEHICLE OR THE LIKE WITH INDEPENDENT CONTROL OF THE PROPELLING AND STEERING BODIES ON BOTH SIDES OF THE VEHICLE, FOR TRANSPORT AND HANDLING WORK

摘要

P TRACKS 1A, 1B OF A HYDRAULIC SHOVEL CAN BE INDIVIDUALLY CONTROLLED BY TWO LEVERS 9A AND 9B ACTING ON DISTRIBUTORS VA, VB. A PARALLEL-SERIES 8 DISTRIBUTOR ALLOWS TO SWITCH FROM A SLOW MARKET TO A FAST MARKET AND REVERSE. THE INVENTION PROVIDES A SWITCHING MECHANISM 13, COMBINED WITH A FAST-WALKING PEDAL 10, THE DISTRIBUTOR 8 AND THE CONTROL LEVERS 9A, 9B, FOR THE AUTOMATIC REDUCTION OF THE SPEED OF THE VEHICLE AT THE BEGINNING OF EVERY CHANGE OF STEERING, IF THE PEDAL 10 IS PRESSED, AND FOR ITS AUTOMATIC ACCELERATION AFTER THE CHANGE OF DIRECTION. THE RISK OF TILTING THE VEHICLE AS A RESULT OF FORGETTING TO RETROGRADER ARE THUS ELIMINATED AND DRIVING IS CONSIDERABLY EASIER. /P
