Description

With reference to Figure 7, the human-machine interface device 18 displays a working area panel 19 with representation of a load diagram showing 20         working areas according to a side view 20 and a plan view 21. The drawings of Figure 7 are provided purely by way of example in order to understand qualitatively the operation of the system according to the invention. The expression “working area” means the definition of a safe 25 operating space, having known the load on the equipment and the type of equipment. Consequently, in the case of a new unrecognized piece of equipment 8, the working areas may be correctly displayed by recalling the previously stored functional parameters for the piece of equipment 8. Returning to Figure 7, it should be noted that the load diagram 30 comprises working areas 20, 21 define respective sub-areas 22, 23, 24 which respectively subdivide the diagram into: -     an area with permitted operations 22 (for example, displayed in green); -      an area with operations close to the permitted limit 23 (for 35 example, displayed in yellow); and -      an area with prohibited operations 24 (for example, displayed in red). In one or more embodiments, in association with the diagrams 20, 21, some operating parameters are also displayed, including: 40         -     ground reach of the load 25; -      lifting angle 26 of the telescopic arm 5; 2026204878   23 Jun 2026 -      height from the ground of the load 27; -     designation 28 of the installed equipment 8 not recognized; -      positioning point of the load 29 on the diagram with side view 20; and 5          -      positioning point of the load 30 on the diagram with plan view 21. Again with reference to the example of Figure 7, the working areas 20, 21 are displayed together with an auxiliary interaction window 31, which displays further operating conditions of the vehicle 1, including: -      summary of the operating limits of use 32 of the vehicle 1; 10          -      indication of the load values 33; and -      indication of the positioning of the load 34 Figure 8 illustrates an operating screen 35 of the human-machine interface device 18 which displays a menu for manual entry of the identification parameters necessary to identify the characteristics of an “unknown” piece of 15 connected equipment 8, useful for determining the new load diagram and the new working areas. As previously indicated, the aforesaid parameters of the new piece of equipment 8 include various characteristic parameters of the piece of equipment 8, such as, for example, the weight, the position of the center of 20 gravity, the maximum capacity and the position of the load center; further optional parameters such as, for example, a parameter expressed as a percentage reduction coefficient or as an additional safety factor. Figure 9 reports a further operating screen 36 of the human-machine interface device 18 which displays the load diagram processed on the basis of 25 the parameters previously entered and the information received from the sensors 13,14,15,16,16'. The diagrams are represented according to a side view 37 and a plan view 38. References 39,40,41,42,43 indicate different capacity ranges of the load diagram according to the side view 37 and plan view 38. 30          Of course, without prejudice to the principle of the invention, the details of construction and the embodiments can be widely varied with respect to those described and illustrated, without thereby departing from the scope of the invention as defined by the claims that follow.
