A telescopic lift arm (1) for a self-propelled operating machine (10) is described, comprising at least three tubular elements (21, 22, 23, 24, 25, 26) having gradually decreasing cross-sections and being telescopically connected to one another to define a support structure, the support structure is designed to move between a stowed configuration, in which one of the tubular elements (21, 22, 23, 24, 25, 26) inserts the tubular element into the other tubular element, and an elongated configuration, in which at least two tubular elements are partially withdrawn. The arm (1) comprises actuation means (5) associated with the tubular elements (21, 22, 23, 24, 25, 26) and configured for actuating at least two tubular elements to pull them out independently of one another and at different speeds.

    描述了一种用于自推进式操作机器(10)的伸缩式提升臂(1),该伸缩式提升臂包括至少三个管状元件(21,22,23,24,25,26),该至少三个管状元件具有的截面逐个减小并且至少三个管状元件伸缩地连接到彼此以限定支撑结构,该支撑结构设计成在收起构造与伸长构造之间移动,在该收起构造中,这些管状元件(21,22,23,24,25,26)中的一个插管状元件入另一个管状元件中,在该伸长构造中,至少两个管状元件被部分地抽出。臂(1)包括致动装置(5),该致动装置与管状元件(21,22,23,24,25,26)相关联,并且配置成用于致动至少两个管状元件,以将该两个管状元件彼此独立地且以不同的速度拉出。
