    摘要: A mobile telescopic crane (1) has a telescopic jib (9) with at least three sub-jibs (16 to 18). Each of the sub-jibs (16 to 18) is constructed from at least two sub-jib portions (19 to 27) so as to be telescopic in a longitudinal direction (L). Sub-jib portions (19 to 27), which are spaced apart from one another transversely to the longitudinal direction (L), each form a jib portion (11 to 13) with at least one flexurally rigid connecting element (28 to 31). Respectively adjacent jib portions (11 to 13) can be locked mechanically in relation to one another in the longitudinal direction (L). Such a construction of the jib (9) easily provides for an increase in carrying loads as a result of the second moment of area of the jib (9) being increased.

    摘要: A mobile telescopic crane (1) has a telescopic jib (9) with at least four sub-jibs (16 to 19). Each of the sub-jibs (16 to 19) is constructed from at least two sub-jib portions (20 to 31) so as to be telescopic in a longitudinal direction (L). Sub-jib portions (20 to 31) which are spaced apart from one another transversely to the longitudinal direction (L) each form a jib portion (11 to 13) along with at least one flexurally rigid connecting element (32 to 35). Such a construction of the jib (9) easily provides for an increase in carrying loads as a result of the second moment of area of the jib (9) being increased.

    摘要翻译: 移动伸缩式起重机(1)具有带至少四个副臂(16至19)的伸缩臂(9)。 各副支架(16〜19)由至少两个副臂部(20〜31)构成,以便在长度方向(L)上可伸缩。 相对于纵向方向(L)横向彼此间隔开的副臂部分(20至31)每个与至少一个抗挠刚性连接元件(32至35)一起形成臂部分(11至13)。 由于副臂(9)的第二矩区域增加,吊臂(9)的这种结构容易增加载荷。
