Loader Comprising Arm Sections that Have a Space that Runs Along the Arm in Which Tubes or Cables are Arranged

Abstract

The present invention concerns a loader comprising two extended arms arranged parallel to each other, one end of which can be connected to a vehicle and the other end of which can be connected to a tool. At least one arm comprises a space that runs along the arm in which tubes or cables are arranged that make it possible to transport at least one of electricity, hydraulic agent and pneumatic agent, from the vehicle to the various parts of the loader or the tool and from the various parts of the loader or the tool to the vehicle.

1 . A loader comprising two extended arms arranged parallel to each other, one end of which can be connected to a vehicle and the other end of which can be connected to a tool, where at least one arm comprises a space that runs along the arm in which tubes or cables are arranged that make it possible to transport at least one of electricity, hydraulic agent and pneumatic agent, from the vehicle to the various parts of the loader or the tool and from the various parts of the loader or the tool to the vehicle  
       characterised in that 
 the arm comprises a first arm section offering a first part of the space in which the tubes or cables are arranged and that the first space part is formed by the first arm section and a beam element attached to each other.  
 
     
     
         2 . The loader according to  claim 1  in which the space is arranged inside of the arm.  
     
     
         3 . The loader according to  claim 1  in which the beam element is in contact with the lower surface of the first arm section.  
     
     
         4 . The loader according to  claim 1  in which the beam element has an open cross-section such that the space is surrounded by and is limited by the beam element and the first arm section.  
     
     
         5 . The loader according to  claim 4  in which the beam element has essentially the shape of a “C” or a “U”.  
     
     
         6 . The loader according to  claim 1  in which a second arm section offers a second part of the space in which the tubes are arranged.  
     
     
         7 . The loader according to  claim 6  in which the second arm section comprises a beam element that forms the second part of the space.  
     
     
         8 . The loader according to  claim 7  in which the second arm section comprises a beam element with a closed cross-section.  
     
     
         9 . The loader according to  claim 1  in which an extended constructional part is arranged between the two arms and connects the two arms to each other and provides stability to the loader and where a valve housing is arranged at the constructional part to which the tubes, after coming out from the arm are connected.  
     
     
         10 . The loader according to  claim 9  in which the tubes pass out from the arms through an opening directed towards the space behind the constructional part.  
     
     
         11 . The loader according to  claim 10  in which the tubes follow the rear surface of the constructional part to the valve housing.  
     
     
         12 . The loader according to  claim 9  in which at least one covering is arranged over the tubes, parts of the constructional part and the valve housing.
