The invention discloses a monitoring method for single-point or single-side hooking of container through lifting appliance or container carried by lifting appliance during container lifting. A gantrycrane is included, the lifting appliance is arranged on the gantry crane, four spin locks are arranged on the lower surface of the lifting appliance, an angle sensor is arranged on the upper surface of a lifting appliance or a lifting appliance upper frame, and the angle sensor is connected with a controller. The controller is connected with a driving device for controlling the gantry crane. The angle sensor detects the angle of the lifting appliance or the lifting appliance upper frame and judges whether the lifting appliance conducts single-point or single-side hooking on the container belowthe lifting appliance or not or whether the container grabbed by the lifting appliance conducts single-point or single-side hooking on the container piled on the ground or not. The sensor is adoptedfor detection, so that it is sufficiently guaranteed that the gantry crane can stop working and give an alarm in the hoisting process of the gantry crane even if the lifting appliance is hooked with the container below the lifting appliance in a single-point or single-side mode or the container grabbed by the lifting appliance is hooked with the ground stockpiling container in a single-point or single-side mode, and an accident of smashing the ground stockpiling container or hooking an adjacent column-position container is avoided.
本发明公开了集装箱起吊时吊具或吊具所带集装箱单点或单侧勾连集装箱的监控方法,包括龙门吊,龙门吊上设有吊具,吊具的下表面设有四个旋锁,吊具或吊具上架上表面设有角度传感器,角度传感器连接有控制器,控制器连接有控制龙门吊的驱动装置;角度传感器检测吊具或吊具上架的角度,判断吊具是否存在单点或单侧勾连吊具下方的集装箱,或吊具所抓集装箱是否存在单点或单侧勾连地面堆存的集装箱。采用上述传感器进行检测,充分保证了龙门吊起吊过程中,即便存在吊具单点或单侧勾连吊具下方的集装箱,或吊具所抓集装箱是否存在单点或单侧勾连地面堆存的集装箱,龙门吊会暂停工作并报警,避免砸地面堆存箱或勾相邻列位箱的事故发生。
