1.人为因素引发的顶闸事故
1. Accidents of top brake caused by human factors
操作人员工作马虎，不按闸门启闭程序先检查，后操作或原操作人员因事请假，代班人员在不熟悉启闭程序和方法时，盲目操作。如将启闭方向反向，当闸门处在关闭状态时开闸，
Operators work carelessly, do not follow the gate opening and closing procedures first check, then operate or the original operator on business leave, the agent is not familiar with the opening and closing procedures and methods, blindly operate. If the direction of opening and closing is reversed, the gate will be opened when the gate is in the closed state.
电动启闭时按错按钮或人工启闭时摇反方向，把闭闸的方向误操作为开闸;有的是在闭闸时操作人员思想不集中、闸到下限位置未能即时停机，有的是螺杆的限位螺母、限位标志移位，不起限位作用。电动启闭机还会遇到供电部门在维修电器设备或供电线路时电v框格护坡模具 箱体护坡模具 华尔街铜牛 电阻柜 接地电阻柜 电缆保护接地箱 隔离墩模具 化粪池模具源相序变动，致使启闭机上的电动机改变了原运转方向导致启闭机启闭方向的改变，此时如闸门处在关闭状态时开闸，必将发生顶闸事故。
When the electric power is opened or closed, the direction of the closed gate is swing in the opposite direction when the wrong button is pressed or the manual opening and closing is misoperated as the opening of the gate; some operators are not concentrate on the idea when closing the gate, and the position of the gate to the lower limit can not be stopped immediately; some are screw limit nuts, limit signs shifted, which do not play a limiting role. Electric hoist will also encounter the phase sequence change of power supply when the power supply department maintains electrical equipment or power supply lines, which will cause the motor on the hoist to change its original operation direction and lead to the change of hoist hoist hoisting direction. At this time, if the gate is opened when the gate is closed, the jacking accident will occur.
