Abstract (en)
A telescopic boom (2), for a crane (4), comprising a main section (6) and at least a first telescopic boom section (8). The first telescopic boom section (8) is telescopically mounted in the main section (6) and axially movable in relation to the main section (6). The main section (6) is structured to be mounted to a crane boom (10) of said crane (4), to be articulated around a first horizontal axis A1 in relation to said crane boom (10). The telescopic boom (2) further comprises an elongated connecting arrangement (12) comprising a set of hoses for supply of hydraulic oil, said connecting arrangement (12) is routed from a first point (14) located on the inside of the main section (6), between an inner surface (16) of the main section (6) and an outer surface (18) of the first telescopic boom section (8), to a second point (20) located on the inside of the first telescopic boom section (8), by a guiding arrangement (22) provided at a first end (24) of the first telescopic boom section (8). The guiding arrangement (22) comprises a first roller member (26) and a second roller member (28), and is mounted such that said first roller member (26) is arranged in relation to a first side (30) of the first end (24) of the first telescopic boom section (8), and said second roller member (28) is arranged in relation to a second side (32), opposite to the first side (30), of the first end (24) of the first telescopic boom section (8), and wherein said first and the second roller members are mounted to have their axes A2 of rotation parallel to each other and essentially perpendicular to said first horizontal axis A1 to guide the connecting arrangement (12) from/to between said inner surface (16) of the main section (6) and said outer surface (18) of the first telescopic boom section (8) to/from the inside of the first telescopic boom section (8).
