The invention relates to the technical field of engineering equipment, and provides an overhead working truck working range limiting method and device and a controller, and the method comprises the steps that the working range of an overhead working truck is determined in real time; under the condition that the working amplitude is larger than a preset amplitude limiting value, the overhead working truck is controlled to enter a limiting state, and under the limiting state, the overhead working truck cannot be controlled to execute telescopic arm stretching, telescopic arm variable amplitude falling and rotary table rotating actions; under the condition that it is determined that the first-stage forced switch starting instruction is received, the limiting state of the overhead working truck is relieved; and when it is monitored that the working amplitude increment of the overhead working truck is larger than the first preset threshold value and/or it is monitored that the overhead working truck receives the remote control signal, the first-stage forced switch is turned off, and the overhead working truck is controlled to enter the limiting state again. According to the technical scheme, after the working amplitude exceeds the limit, limiting over-amplitude work can be carried out under the condition that working safety is considered.
本发明涉及工程设备技术领域,提供一种高空作业车工作幅度限制方法、装置和控制器,该方法包括:实时确定高空作业车的工作幅度;在工作幅度大于预设限幅值的情况下,控制高空作业车进入限制状态,限制状态下无法控制高空作业车执行伸出伸缩臂、伸缩臂变幅落及转台旋转动作;在确定接收到一级强制开关开启指令的情况下,解除高空作业车的限制状态;在监控到高空作业车的工作幅度增量大于第一预设阈值和/或在监控到高空作业车接收到遥控控制信号的情况下,关闭一级强制开关,再次控制高空作业车进入限制状态。本技术方案在工作幅度超限后,在考虑工作安全的情况下还可以进行限制超幅做工。
