Abstract (en)

A boom (1') comprising at least three telescopic boom sections, a first transmission member (10) and a second transmission member (20). The respective transmission member is arranged inside the boom sections and has a first point fixed in relation to an inner boom section and a second point fixed in relation to an outer boom section. A first pulley (13) is arranged to act on the first transmission member so as to displace the outer boom section outwards in relation to an intermediate boom section when the intermediate boom section is displaced outwards in relation to the inner boom section under the effect of an actuating member (6). A second pulley (23) is arranged to act on the second transmission member so as to displace the outer boom section inwards in relation to the intermediate boom section when the intermediate boom section is displaced inwards in relation to the inner boom section under the effect of the actuating member.
