Abstract
Described is self-propelled working machine (1) provided with organ (10) for moving a load and equipped with a safety system designed to prevent a risk of instability and comprising means (3) for detecting a position and a weight of the load and further comprising a processing unit (2) connected to said detection means (3) and in turn comprising: a checking module (21) configured for comparing the weight of the load with a reference value, selected on the basis of a position of the load; and a limiting module (22) configured for producing a limiting signal suitable for limiting the movement of the movement organ (10), following the comparison performed by the checking module. The reference value is independent of an angular position of the movement organ (10).

A self-propelled working machine (1) provided with an organ (10) for moving a load and equipped with a safety system designed to prevent a risk of instability and comprising means (3) for detecting a position and a weight of the load and further comprising a processing unit (2) connected to said detection means (3) and comprising:
- a checking module (21) configured for comparing the weight of the load with a reference value, selected on the basis of a position of the load;
- and a limiting module (22) configured for producing at least one limiting signal suitable for limiting the movement of the movement organ (10), following the comparison performed by the checking module;
- said reference value being independent of an angular position of the movement organ (10).
A operating method of a working machine (1) provided with an organ (10) for moving a load, comprising the following steps:
- detecting a position and a weight of the load;
- comparing the weight of the load with a reference value, selected on the basis of a position of the load which does not depend on the angular position of the movement organ (10);
- and
- limiting or freely allowing movement of the above-mentioned organ (10) based on the comparison performed.
