Abstract

A simulation system for telehandlers that are equipped with a movable operating arm designed to lift and move loads, and stabilisers that include a plurality of movable stabilising arms. An acquisition module is configured to receive at least functional parameters relating to operating conditions of the stabilising arms. A calculation module is configured to determine a potential stability condition as a function of the operating parameters. And an output module is configured to provide an operator with information representing the condition of potential stability.

First claim

The invention claimed is:

1. A simulation system for telehandlers equipped with a movable operating arm, designed to lift and move loads and stabilisers, comprising a plurality of movable stabilising arms, said system comprising electronic processing means which include:
an acquisition module configured to receive at least functional parameters relating to operating conditions of said stabilising arms;
wherein said acquisition module is set up to receive at least one functional parameter concerning a position where it is possible to place a load;

a calculation module configured for determining at least one potential stability condition, as a function of said operating parameters;
wherein said calculation module is configured to determine whether the telehandler would be potentially stable if said load is located in said position and, in that case, determine a lifting angle and a length of the arm suitable to allow the load to be located in the above-mentioned position; and
an output module configured to provide an operator with information representing said condition of potential stability.

2. The system according to claim 1 , wherein said acquisition module is set up to receive a plurality of functional parameters relative to arrangements of the respective stabilising arms.

3. The system according to claim 1 , wherein the acquisition module is set up to receive at least one functional parameter relative to said load.

4. The system according to claim 1 , used with a telehandler comprising a movable carriage on wheels on which is located a rotary turret which has the operating arm, wherein the above-mentioned acquisition module is set up for receiving at least one functional parameter relative to the angular position of said turret.

5. The system according to claim 1 , wherein the acquisition module is set up to receive a functional parameter relative to a height at which said load can be positioned and a functional parameter concerning a relative distance at which the load can be positioned.

6. The system according to claim 1 , wherein the calculation module-P is configured to determine maximum load values, as a function of possible positions in which it can be positioned by the arm, corresponding to a potential stability of the telehandler.

7. The system according to claim 1 , wherein the calculation module comprises a first moment module configured to determine a stabilising moment of the telehandler as a function of said operating parameters, a second moment module to determine a tipping moment as a function of the above-mentioned operating parameters and a comparison module to check if the ratio between said stabilising moment and said tipping moment is greater than or equal to or less than a predetermined safety factor.

8. The system according to claim 1 , wherein said output module is configured for producing display signals, as a function of the potential stability condition, of said angle and of said length determined by the calculation module and designed to generate, using display means, graphical indices representing said stability condition, said angle and said length.

9. The system according to claim 6 , wherein the output module is configured for producing display signals, as a function of the determinations of the calculation module, designed to produce, using display means, graphical indices representing said maximum load values for respective possible positions in which the load can be carried in conditions of stability of the telehandler.

10. The system according to claim 1 , comprising a user interface connected to or integrated with the processing means and configured for the insertion or the selection of said functional parameters by an operator and for the representation, for use by the operator, of graphical indices associated with the conditions of potential stability determined by the calculation module.

11. The system according to claim 1 , wherein the processing means include a control module configured to generate a control signal designed to automatically move the arm to the position associated with the length and the angle determined by the calculation module and corresponding to the destination position of the load.

12. The system according to claim 11 , wherein the control module is designed to generate said control signal following receipt of an enabling signal produced on a command which can be actuated by an operator.
