用于在自走式起重机的主悬臂上添装和拆卸附加装置的方法和装置
摘要：
本发明涉及一种用于在自走式起重机的主悬臂上、在不用辅助起重机的情况下添装和拆卸由多个单个元件构成的附加装置的方法和装置。在按照本发明的方法中，将由多个部件构成的附加装置(2)的一个部件(2.1)绕上面的回转点(C)转动地抬升到倾斜位置并且将主悬臂(1.1)的头部(1.2)与附加装置(2)的面向自走式起重机的部件(2.1)的处于倾斜位置的端部的下端能转动地栓紧。借助于提升绳索(7)将全部部件(2.1至2.7)相互间和朝向主悬臂(1.1)对准地抬升并在该位置相互间和与主悬臂栓紧。本发明还涉及一种用以实施该方法的移动装置。
摘要（英）：

The invention relates to a method and to a device for attaching and removing an additional device comprising individual elements to and from the main jib of a mobile crane using no auxiliary crane. In the method according to the invention, a partial piece (2.1) of the additional device (2) composed of partial pieces is raised into an inclined position while being rotated about an upper pivot point (C), and the head (1.2) of the main jib (1.1) is bolted to the lower end of the inclined end of the partial piece (2.1) of the additional device (2) facing the mobile crane so as to be able to rotate. Using a hoist cable (7), all partial pieces (2.1 to 2.7) are raised in alignment with respect to each other and the main jib (1.1), and are bolted to each other in this position and to the main jib. The invention furthermore relates to a displacement device for carrying out the method according to the invention.
