Problems solved by technology

The disadvantage of the installation from the prior art exemplified here is that a large space is necessarily required for the pivoting of the top boom about a vertical axis of rotation, but such a large space is not mandatory at every location of use. space

Embodiment Construction

[0044] The principle of the folding top mounting is explained below by the description of the drawings. According to the present invention, the top of the folding is continuously guided in a hydraulic manner, which helps to reduce the probability of the fault. Further, during the transition between the transport position and the working position, the folded top is connected to the main cantilever connection through the hinge connection (bracket 41 or pivot shaft 33).

[0045] in Figure 1A The folded top 40 is visually arranged laterally from the main cantilever 30 of the mobile crane 100. Here, the folded top 40 is hung on two brackets 41, which is used to pivot the folded top 40 to 180 degrees, and place the folded top 40 onto the main cantilever 30. The main cantilever 30 is particularly a retractable main creator. The folding top 40 is also fixed to the upper side of the main cantilever 30 through the bracket 41. A pivotally coupled bracket 41 capable of realizing the main cant...

Abstract

The invention relates to a folding top hinge block for pivoting a pivotable folding top into an operating position, comprising: a base frame with removable fasteners for fixed mounting to a main boom; an adjustment cylinder , which is pivotally connected to the base frame by one of its ends; the middle frame, which is pivotally connected to the base frame at the first section, wherein the other end of the adjustment cylinder is connected to the middle frame The second section is pivotably connected, and all the pivotable connections of the intermediate frame and the adjustment cylinder have pivot axes parallel to each other, wherein the intermediate frame is pivotally connected with the steering rod, and the lockable telescopic rod is pivotable Arranged at one of the two end sections of the steering rod, the telescopic rod is pivotally connected with the base frame by its end spaced from the steering rod, and the two end sections of the steering rod The other end section is pivotally connected to the linkage assembly.

Description

Technical field [0001] The present invention relates to a folded top hinge block and a method for mounting the top of the folding. Background technique [0002] In a particular type of crane, the top cantilever is typically fixed on the roller head of the retractable main cantilever. Here, the top cantilever is usually unstretched as the main cantilever itself. Conversely, during the assembly of the crane, the top cantilever needs to be arranged onto the roller head of the main cantilever. In the working operation, the top cantilever is tilted relative to the main cantilever. [0003] From the prior art, for example, a mobile crane is known, and its top cantilever is located on the side of the main cantilever side of the horizontal arrangement. In order to arrange the top cantilever on the roller head of the main cantilever, the top cantilever is typically bolted with the roller head to pivot forward from the transport position from the vertical axis. After pivoting, the longitud...
