The present invention relates to a device pertaining to vehicle cranes, preferably cranes of the type which are arranged on lorries and by means of which pulp wood/timber is loaded onto the lorry and/or associated trailer. The crane comprises an essentially vertically disposed pillar 1, which can be rotated both anti- clockwise and clockwise relative to a central position. The crane further comprises pressure hoses 15,16 and return hoses 16,15 for hydraulic oil. First sections of the hoses 15,16 at the lower part of the pillar 1 are intended to perform motions in the horizontal plane beneath platforms arranged in the crane whenever the pillar is rotated and second sections of the hoses 15,16 at a higher level have an essentially vertical extent close up to the pillar. Smooth and simple hose traction is thereby obtained, together with a simultaneous reduction in the mechanical wear on the hoses. <IMAGE> |
