The present invention relates to a frame (1) which is to be mounted onto a ski slope maintenance vehicle (15) having a winch (17), and which supports a jib (3) for directing a cable (21) between a reeling drum (23) of the winch (17) and a point for attaching the cable (21) for pulling the vehicle (15), wherein said frame (1) includes a deformable quadrilateral structure (5) that makes it possible to vary the height of the jib (3).
B66D 1/38 - Guiding, or otherwise ensuring winding in an orderly manner, of ropes, cables, or chains by means of guides movable relative to drum or barrel
B65H 75/42 - Cores, formers, supports, or holders for coiled, wound, or folded material, e.g. reels, spindles, bobbins, cop tubes, cans specially adapted or mounted for storing and repeatedly paying-out and re-storing lengths of material provided for particular purposes, e.g. anchored hoses, power cables involving the use of a core or former internal to, and supporting, a stored package of material mobile or transportable attached to, or forming part of, mobile tools or machines
B65H 75/00 - Storing webs, tapes, or filamentary material, e.g. on reels
B66D 1/36 - Guiding, or otherwise ensuring winding in an orderly manner, of ropes, cables, or chains
The present invention relates to a maintenance vehicle (20) for skip slopes, on which a mounting (1) for a drum (7) for reeling a cable (13) is mounted, said mounting comprising: a base (2) to be attached onto the chassis of the vehicle (20); a pivotable hinged portion (3) supporting the drum (7), the pivot pin (5) being perpendicular to the rotational axis (9) of the spool (7); and a means (11) for actuating the pivotable hinged portion (3) about the pivot pin (5), in an alternating manner, between first and second predetermined positions during the reeling of the cable (13) in order to enable the regular reeling of the cable (13) over the axial width (L) of the drum (7).
B65H 75/42 - Cores, formers, supports, or holders for coiled, wound, or folded material, e.g. reels, spindles, bobbins, cop tubes, cans specially adapted or mounted for storing and repeatedly paying-out and re-storing lengths of material provided for particular purposes, e.g. anchored hoses, power cables involving the use of a core or former internal to, and supporting, a stored package of material mobile or transportable attached to, or forming part of, mobile tools or machines
The invention relates to a vehicle for the maintenance of ski slopes, including a frame (11) for supporting a winch (9), a winch intended to be mounted on the frame and including a winding drum (17) and a winding motor (27) associated with the drum, a cable (15) to be unwound and wound around the drum by the winding motor so as to generate a compensation for the pulling torque of the vehicle, wherein said cable is made of a synthetic material.
B62D 57/04 - Vehicles characterised by having other propulsion or other ground-engaging means than wheels or endless track, alone or in addition to wheels or endless track having other than ground-engaging propulsion means, e.g. having propellers
E01H 4/02 - Working on surfaces of snow or ice in order to make them suitable for traffic or sporting purposes, e.g. by compacting snow for sporting purposes, e.g. preparation of ski trails
