Abstract

The invention relates to a handling machine ( 1 ) comprising:
a rotating chassis; a lifting arm ( 7 ); a first assembly comprising a device for storing electrical energy ( 9 ); a second assembly comprising a fuel cell ( 10 ) which is connected to the device for storing electrical energy ( 9 ) via a connecting circuit ( 35 ); and a third assembly comprising at least one tank ( 11 );

wherein one of the first, the second and the third assemblies is fixed to one of the lower and upper structures ( 2, 3 ) and the two others of the first, second and third assemblies are fixed to the other of the lower and upper structures ( 2, 3 );

First claim

1 . Handling machine ( 1 ) comprising:
a chassis comprising a lower structure ( 2 ) and an upper structure ( 3 ) rotatably mounted on the lower structure ( 2 ) about a vertical axis; a lifting arm ( 7 ) which is movably mounted on the upper structure ( 3 ); a first assembly comprising a device for storing electrical energy ( 9 ), a second assembly comprising a fuel cell ( 10 ) which is configured to generate electrical energy designed to be stored in the device for storing electrical energy ( 9 ), said fuel cell ( 10 ) being electrically connected to the device for storing electrical energy ( 9 ) via a connecting circuit ( 35 ); and a third assembly comprising at least one tank ( 11 ) designed to contain hydrogen and connected to the fuel cell ( 10 ) via a supply line ( 18 ) in order to supply it with hydrogen;
said supply line ( 18 ) comprising a pressure controller ( 19 ), an upstream portion ( 20 ) connecting the tank ( 11 ) and the pressure controller ( 19 ) and a downstream portion ( 21 ) connecting the pressure controller ( 19 ) and the fuel cell ( 10 ),
wherein one of the first, the second and the third assemblies is fixed to one of the lower and upper structures ( 2 , 3 ) and the two others of the first, second and third assemblies are fixed to the other of the lower and upper structures ( 2 , 3 );
wherein the pressure controller ( 19 ) and the upstream portion ( 20 ) of the supply line ( 18 ) are fixed to that of the lower ( 2 ) and upper structures ( 3 ) to which the third assembly is fixed; and wherein the handling machine ( 1 ) comprises a rotating joint ( 25 ) connecting the lower structure ( 2 ) and the upper structure ( 3 ), the downstream portion ( 21 ) of the supply line ( 18 ) passing through said rotating joint ( 25 ) when the second assembly and the third assembly are respectively fixed to one another of the lower and upper structures ( 2 , 3 ) and/or the connecting circuit ( 35 ) passing through said rotating joint ( 25 ) when the second assembly and the first assembly are respectively fixed to one and the other of the lower and upper structures ( 2 , 3 ).

2 . The handling machine ( 1 ) as claimed in claim 1 , wherein one of the first, the second and the third assemblies is fixed to the upper structure ( 3 ) and the two others of the first, second and third assemblies are fixed to the lower structure ( 2 ) and housed in a first box and a second box of said lower structure ( 2 ).

3 . The handling machine ( 1 ) as claimed in claim 2 , wherein the first box and the second box are formed in the lower structure ( 2 ) on either side of a longitudinal median plane of the handling machine ( 1 ).

4 . The handling machine ( 1 ) as claimed in claim 2 or 3 , comprising a driver's cab ( 6 ) mounted on the upper structure ( 3 ) and wherein that of the first, second and third assemblies which is fixed to the upper structure ( 3 ) and said driver's cab ( 6 ) are positioned on either side of the lifting arm ( 7 ).

5 . The handling machine ( 1 ) as claimed in any one of claims 2 to 4 , wherein the first assembly, the second assembly and the connecting circuit ( 35 ) are fixed to the lower structure ( 2 ), the third assembly, the pressure controller ( 19 ) and the upstream portion ( 20 ) of the supply line ( 18 ) being fixed to the upper structure ( 3 ) and the downstream portion ( 21 ) of the supply line ( 18 ) passing via the rotating joint ( 25 ).

6 . The handling machine ( 1 ) as claimed in any one of claims 2 to 4 , wherein the first assembly, the third assembly, the pressure controller ( 19 ) and the upstream portion ( 20 ) of the supply line ( 18 ) are fixed to the lower structure ( 2 ), the second assembly being fixed to the upper structure ( 3 ) and wherein the downstream portion ( 21 ) of the supply line ( 18 ) and the connecting circuit ( 35 ) pass via the rotating joint ( 25 ).

7 . The handling machine ( 1 ) as claimed in any one of claims 2 to 4 , wherein the second assembly, the third assembly and the supply line ( 18 ) are fixed to the lower structure ( 2 ), the first assembly being fixed to the upper structure ( 3 ) and the connecting circuit ( 35 ) passing via the rotating joint ( 25 ).

8 . The handling machine ( 1 ) as claimed in claim 1 , wherein one of the first, the second and the third assemblies is fixed to the lower structure ( 2 ) and the two others of the first, second and third assemblies are fixed to the upper structure ( 3 ) and housed in a first box and a second box of said upper structure ( 3 ).

9 . The handling machine ( 1 ) as claimed in claim 8 , wherein the first box and the second box are formed in the upper structure ( 2 ) on either side of the lifting arm ( 7 ).

10 . The handling machine ( 1 ) as claimed in claim 8 or 9 , wherein the first assembly, the third assembly, the pressure controller ( 19 ) and the upstream portion ( 20 ) of the supply line ( 18 ) are fixed to the upper structure ( 3 ), the second assembly being fixed to the lower structure ( 2 ) and wherein the downstream portion ( 21 ) of the supply line ( 18 ) and the connecting circuit ( 35 ) pass via the rotating joint ( 25 ).

11 . The handling machine ( 1 ) as claimed in claim 8 or 9 , wherein the first assembly, the second assembly and the connecting circuit ( 35 ) are fixed to the upper structure ( 3 ), wherein the third assembly, the pressure controller ( 19 ) and the upstream portion ( 20 ) of the supply line ( 18 ) are fixed to the lower structure ( 2 ), the downstream portion ( 21 ) of the supply line ( 18 ) passing via the rotating joint ( 25 ).
