阅读说明：本技术 可扩展重型设备、长形拉动元件以及使用可扩展重型设备 (Expandable heavy equipment, elongated pulling element and use of expandable heavy equipment ) 是由 R·J·范德舒伊特 于 2019-01-23 设计创作，主要内容包括：一种可扩展重型设备(1),该可扩展重型设备(1)包括第一框架元件(5)、连接器(11)、至少一个长形拉动元件(14)和附加框架元件(7)。拉动元件(14)用第一联接器(31)连接到第一框架元件(5),并且用第二联接器(35)连接到附加框架元件(7)中的一个框架元件(9)。拉动元件(14)在运输状况下处于折叠状态,并且在作业状况下处于伸展状态。拉动元件(14)包括从第一联接器(31)延伸到第二联接器(35)的承载纤维(141)。拉动元件(14)包括至少一个柔性部分(43)和至少两个刚性部分(45)。柔性部分(43)具有比两个刚性部分(45)更小的弯曲刚度,并且使拉动元件(14)能够被布置成处于折叠状态。(An expandable heavy equipment (1), the expandable heavy equipment (1) comprising a first frame element (5), a connector (11), at least one elongated pulling element (14) and an additional frame element (7). The pulling element (14) is connected to the first frame element (5) with a first coupling (31) and to one of the additional frame elements (7) (9) with a second coupling (35). The pulling element (14) is in a folded state in the transport condition and in an extended state in the working condition. The pulling element (14) comprises a carrier fiber (141) extending from the first coupling (31) to the second coupling (35). The pulling element (14) comprises at least one flexible portion (43) and at least two rigid portions (45). The flexible portion (43) has a smaller bending stiffness than the two rigid portions (45) and enables the pulling element (14) to be arranged in a folded state.)
