A multifunctional lifting vehicle (1) comprising: - a base frame (2), - a lifting assembly (5) including at least one operating arm equipped with a connection section for mounting a tool (8), - a portable radio-controlled device (12) configured for controlling the vehicle (1) from a remote position, - wherein the portable radio-controlled device (12) comprises a plurality of control elements which can be operated manually by an operator for driving relative movements and functions of the vehicle (1), - wherein the portable radio-controlled device (12) comprises at least one control display screen (19) configured and programmed to display a plurality of movements and/or functions of the vehicle (1) corresponding to respective actuations of the control elements of the radio-controlled device (12), - wherein said portable radio-controlled device (12) comprises an operating mode selector (18) for selecting a specific operating mode of the vehicle (1), from those available, according to the type of tool (8). - wherein the display screen (19) is configured and programmed to dynamically display functions and movements of the vehicle (1) responsive to respective control elements of the radio-controlled device (12), as a function of the selected operating mode and/or the control elements of the radio-controlled device (12) activated in real time. - wherein the radio-controlled device (12) is configured and programmed to display on the screen (19) a digital representation of said control elements which are available for use according to the selected operating mode and/or the stability conditions of the vehicle (1), without displaying the control elements that are non-operable due to the current operating conditions of the vehicle (1), - characterized in that , upon reaching a stability limit condition, the radio-controlled device (12) is configured and programmed to display only the control elements that allow the vehicle (1) to return to a condition with increased stability.
  2. A multifunctional lifting vehicle (1) according to any of the preceding claims, characterized in that : - said control elements comprise at least one joystick (15), - a portion of the screen (19) is constantly dedicated to a digital reproduction of the joystick (15) and its relative degrees of freedom, so as to show at said portion (19) multiple icons representing vehicle movements and functions which can be controlled by means of the joystick (15).
  3. A multifunctional lifting vehicle (1) according to claim 1, characterized in that a color is associated with each operating mode of the vehicle (1), shown on the screen (19) during the dynamic representation of the controls available.
  4. A multifunctional lifting vehicle (1) according to claim 1, characterized in that the control elements of the radio-controlled device (12) activated in a given instant are highlighted on the screen (19), so as to constantly indicate to the operator the control elements currently actuated.
  5. A multifunctional lifting vehicle (1) according to claim 2, characterized in that the digital reproduction of the joystick (15) comprises directional keys (24) in which respective icons are shown, said icons representing vehicle functions that can be controlled with the relative directional key.
  6. A multifunctional lifting vehicle (1) according to any of the preceding claims, characterized in that a main part (22) of the screen (19) is arranged to display relevant information of the selected operating mode, in particular, in association with a fork mode, a schematic representation of the vehicle (1) and related operating parameters including the height from the ground of the tool (8) and the angle of inclination of the arm with respect to the base frame (2).
  7. A multifunctional lifting vehicle (1) according to any of the preceding claims, characterized in that said screen (19) is arranged to display in all the windows relevant information for operating the device (12) and controlling the vehicle (1), including the amount of fuel contained in the vehicle tank, the battery charge of the device (12), the intensity of the transmission signal, the bubble level and the stability percentage of the vehicle (1).

Description

Field of the invention The present invention relates to a multifunctional lifting vehicle comprising a base frame,a lifting assembly including at least one operating arm equipped with a connection section for mounting a tool,a portable radio-controlled device designed to control the vehicle from a remote position,wherein the portable radio-controlled device comprises a plurality of control elements which can be operated manually by an operator for driving relative movements and functions of the vehicle. Description of the prior art Lifting vehicles of the above type may be equipped with different types of tools, such as forks, shovels, aerial platforms, etc. During operation, the load applied to the tool located at the end of the telescopic arm can vary widely. According to a technique now consolidated in the technological sector in question, the lifting vehicle may be advantageously operated remotely using a portable radio-controlled device, designed to control the vehicle from a remote position. The radio control is equipped with a plurality of control elements, such as control levers, joysticks, and/or buttons, to be operated manually to control a plurality of movements and functions of the lifting vehicle. Currently, in order to guide the user in the correct use of the remote controls, the radio control itself may bear various schematic illustrations on its front, applied for example with silk-screen printing, which show movements and/or functions of the vehicle responding to respective actuations of the control elements. However, this representation is often confusing and not very intuitive, also in relation to the fact of having to prepare different illustrations according to the different operating modes of the multifunctional vehicle. Documents US 2021/276848 A1 and US 2023/048274 A1 and US 11524879 B2 describe solutions having the characteristics indicated at the beginning of the description, in which the radio control device includes a display screen. The present invention is inspired by the desire to develop further improvements. Document US 2021/276848 A1 discloses a multifunctional lifting vehicle according to the preamble of claim 1. Object of the invention The object of the present invention is to propose a multifunctional lifting vehicle and a relative portable radio-controlled device for overcoming the problems indicated above. One object of the present invention is, therefore, to create a clear and effective display of the movements and functions that can be controlled by the radio-controlled device, according to the different operating modes of the vehicle. Summary of the invention According to the present invention, the aforesaid objectives are achieved by a lifting vehicle having the characteristics indicated in claim 1. Additional characteristics of the invention are indicated in the attached claims, which form an integral part of the disclosure administered herein in relation to the invention. Brief description of the drawings The present invention will now be described in detail with reference to the attached drawings, given purely by way of non-limiting example, wherein: Figure 1 is a schematic view of a lifting vehicle according to one embodiment;Figure 2 is an enlarged view of an example of a tool connected to the frame of the vehicle illustrated in the previous Figure,Figure 3 is a schematic view of a portable radio-controlled device according to an embodiment of the invention; andFigures 4-6 show different operating screens as an example of a command display screen included on the radio-controlled device. Detailed description of the embodiments of the invention In the following description, various specific details are illustrated aimed at a thorough understanding of examples of one or more embodiments. The embodiments may be implemented without one or more of the specific details, or with other methods, components, materials, etc. In other cases, known structures, materials or operations are not shown or described in detail to avoid obscuring various aspects of the embodiments.
