Abstract
The present invention concerns a loader comprising two arm constructions (2a, 2b) arranged parallel to each other, and which in turn constitute extended arm sections (3, 3a) and parallel struts (7) arranged above the extended arm sections (3, 3a). The invention is characterised in that each parallel strut (7) is constituted by an extended beam construction with an open cross-section demonstrating a longitudinal opening (Y) directed towards the arm section (3, 3a).
Claims (7)
1. A loader comprising two arm constructions (2a, 2b) arranged parallel to each other, and which in turn comprise extended arm sections (3, 3a) and parallel struts (7) arranged above the extended arm sections (3, 3a) characterised in that each parallel strut (7) is constituted by an extended beam construction with an open cross-section demonstrating a longitudinal opening (Y) directed towards the arm section (3, 3a).
2. The loader according to claim 1 in which the parallel strut (7) sits astride the arm section (3, 3a).
3. The loader according to claim 1 or 2 in which the parallel strut (7) comprises two side sections (7.1, 7.2) and a central section (7.3).
4. The loader according to claim 3 in which the two side sections (7.1, 7.2) of the parallel strut (7.1, 7.2) extend downwards a certain extent (Z) on each side of the arm section (3, 3a) and in which the central part (7.3) is located above the arm section (3, 3a).
5. The loader according to any one of the preceding claims in which a space (X) is limited by the parallel strut (7, 7.1, 7.2, 7.3) and the arm section (3, 3a).
6. The loader according to any one of the preceding claims in which the parallel strut (7) is principally C-shaped or U-shaped when seen in a section transverse to the direction of extension of the parallel strut.
7. The loader according to any one of the preceding claims in which the parallel strut (7) demonstrates a bent form along its longitudinal direction (L).
