The invention discloses a cantilever crane system for an arch frame vehicle. The cantilever crane system comprises a telescopic arm and a mounting base mounted on a chassis of the arch frame vehicle,the telescopic arm is mounted on the mounting base through a transition arm, the two ends of the transition arm are a first end and a second end correspondingly, the first end is hinged to the mounting base, the telescopic arm is hinged to the second end, a first telescopic oil cylinder used for driving the transition arm to rotate relative to the mounting base is hinged between the mounting baseand the transition arm, and a second telescopic oil cylinder used for driving the telescopic arm to rotate relative to the transition arm is hinged between the transition arm and the telescopic arm; and arrangement conditions required to be met by hinge points among the transition arm, the telescopic arm, the mounting base, the first telescopic oil cylinder and the second telescopic oil cylinder are arranged. The cantilever crane system has the advantages of being simple and compact in structure, low in cost, good in safety, high in application flexibility, wide in application range and the like.

    本发明公开了一种用于拱架车的臂架系统,包括伸缩臂和安装在拱架车底盘上的安装座,伸缩臂通过过渡臂安装在安装座上,过渡臂的两端分别为第一端和第二端,第一端与安装座铰接,伸缩臂与第二端铰接,安装座与过渡臂之间铰接安装有用于驱动过渡臂相对于安装座转动的第一伸缩油缸,过渡臂与伸缩臂之间铰接安装有用于驱动伸缩臂相对于过渡臂转动的第二伸缩油缸;并设置了过渡臂、伸缩臂、安装座、第一伸缩油缸和第二伸缩油缸相互之间的铰接点所需满足的布置条件。本发明具有结构简单紧凑、成本低、安全性好、运用灵活性高、适用范围广等优点。
