The invention relates to the field of engineering machinery, and discloses a cantilever crane control system and engineering machinery, the cantilever crane control system comprises a cantilever crane hydraulic circuit, a main oil inlet valve, a posture detection device, a cantilever crane control mechanism and a processing device, the arm support control mechanism comprises a control handle, a contact switch provided with a first trigger piece and a trigger device provided with a first contact, and the control handle can drive the first trigger piece to make contact with the first contact, so that the contact switch sends out a first trigger signal; the processing equipment is electrically connected with the arm support hydraulic circuit, the main oil inlet valve, the posture detection equipment and the contact switch, and is configured to control the arm support to generate posture change towards the forward inclination direction when a first trigger signal is received and the posture of the arm support accords with a preset safety posture; and when the first trigger signal is received and the posture of the boom does not conform to the preset safety posture, the main oil inlet valve is controlled to be closed. The boom control system is simple in arrangement and low in cost, amplitude limiting failure can be effectively avoided, and operation safety is improved.
本申请涉及工程机械领域,公开了一种臂架控制系统和工程机械,该臂架控制系统包括臂架液压回路、总进油阀、姿态检测设备、臂架操纵机构以及处理设备,其中,臂架操纵机构包括操纵手柄、设有第一触发件的触点开关和设有第一触点的触发装置,操纵手柄能够带动第一触发件与第一触点接触,使得触点开关发出第一触发信号;处理设备与臂架液压回路、总进油阀、姿态检测设备和触点开关电连接,且配置为:在接收到第一触发信号且臂架姿态符合预设安全姿态时控制臂架朝着前倾方向产生姿态变化;在接收到第一触发信号且臂架姿态不符合预设安全姿态时控制总进油阀关闭。本申请的臂架控制系统布置简单且成本较低,能够有效避免限幅失效,提高作业安全性。
