Abstract

The present invention concerns a loader (1) comprising two extended arms (2a, 2b) arranged parallel to each other, one end (A) of which can be connected to a vehicle and the other end (B) of which can be connected to a tool (7). At least one arm (2a, 2b) comprises a space (X1, X2) that runs along the arm in which tubes or cables (9) 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 (4, 11) of the loader or the tool (7) and from the various parts (4, 11) of the loader or the tool (7) to the vehicle.

Claims (12)

1. A loader (1) comprising two extended arms (2a, 2b) arranged parallel to each other, one end (A) of which can be connected to a vehicle and the other end (B) of which can be connected to a tool (7), where at least one arm (2a) comprises a space (X1, X2) that runs along the arm in which tubes or cables (9) 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 (4, 11) of the loader or the tool (7) and from the various parts (4, 11) of the loader or the tool (7) to the vehicle characterised in that the arm (2a) comprises a first arm section (3.1) offering a first part (X1) of the space in which the tubes or cables (9) are arranged and that the first space part (X1) is formed by the first arm section (3.1) and a beam element (3.1a) attached to each other.
2. The loader according to claim 1 in which the space (X1, X2) is arranged inside of the arm (2a, 2b).
3. The loader according to claim 1 or 2 in which the beam element (3.1a) is in contact with the lower surface (3.1b) of the first arm section.
4. The loader according to anyone of claims 1-3 in which the beam element (3.1a) has an open cross-section such that the space (X1) is surrounded by and is limited by the beam element (3.1a) and the first arm section (3.1).
5. The loader according to claim 4 in which the beam element (3.1a) has essentially the shape of a "C" or a "U".
6. The loader according to any one of claims 1-5 in which a second arm section (3.2) offers a second part (X2) of the space in which the tubes (9) are arranged.
7. The loader according to claim 6 in which the second arm section (3.2) comprises a beam element that forms the second part (X2) of the space.
8. The loader according to claim 7 in which the second arm section (3.2) comprises a beam element with a closed cross-section.
9. The loader according to any one of claims 1-8 in which an extended constructional part (10) is arranged between the two arms (2a, 2b) and connects the two arms (2a, 2b) to each other and provides stability to the loader (1) and where a valve housing (11) is arranged at the constructional part (10) to which the tubes (9), after coming out from the arm (2a, 2b), are connected.
10. The loader according to claim 9 in which the tubes (9) pass out from the arms (2a, 2b) through an opening (D) directed towards the space (10B) behind the constructional part.
11. The loader according to claim 10 in which the tubes (9) follow the rear surface (10B) of the constructional part to the valve housing (11).
12. The loader according to any one of claims 9-11 in which at least one covering (14a-14c) is arranged over the tubes (9), parts of the constructional part (10) and the valve housing (11).
