The invention discloses a cantilever crane device of an insulating overhead working truck. The cantilever crane device comprises a lower arm part provided with an upper base knuckle arm and an upper telescopic arm, an upper arm part provided with a base knuckle arm and a basic telescopic arm, and a cantilever crane state monitoring device. The cantilever crane device can realize independent stretching of the upper arm part and the lower arm part and can monitor the state of a cantilever crane in real time. The operation height is higher under the condition of the same length size of the wholevehicle, and the state of the cantilever crane is monitored in real time, so that an insulating operation platform can be prevented from moving to a dangerous operation area to cause a whole vehicle tipping accident, the operation stability of the whole vehicle is ensured, and meanwhile, self-damage collision of cantilever crane parts due to misoperation is prevented; and potential safety hazardsof a working truck are reduced.
本发明公开了一种绝缘高空作业车的臂架装置,包括设有上基础节臂和上伸缩臂的下臂部分、设有基础节臂和基础伸缩臂的上臂部分以及臂架状态监测装置,其可实现上臂部分、下臂部分单独伸缩,并且可以实时监测到臂架状态,进而实现在相同整车长度尺寸下,作业高度更高,并通过实时监测臂架状态,可以防止绝缘作业平台运动至危险作业区域发生整车倾翻事故,保证整车作业的稳定性,同时防止由于误操作发生臂架部分出现自损碰撞,从而降低作业车的安全隐患。
