低净空钢丝绳电动葫芦广泛的应用于一下矿山、工厂等地方，都安装有断火限位器，可根据客户的具体使用需要来进行调整，虽然断火限位器是有一定的作用的在安全方面，但是也有一些弊端，如果遇到断火限位器出现故障了，我们该如何解决呢，本文主要介绍一下钢丝绳电动葫芦系列产品的解决方法。
，严禁斜拉。因为斜拽是因为导航线向一侧倾斜，可能会使导航线折断而受损。
第二，为了防止不受限制的位置变更，经过适当的调整后，限制火灾发生的装置的上限和下限将被固定在原位。
第三、5条线路，b级是共同线路，puthy road侧面的端子接近AC以上的liz接触器，如果接触器AC以上的端子掉下这个位置，反方向的情况下，升降机插在刹车断裂上时，电嘴仍能向上，但不能向下。与此相反，当羽绒服到达屏蔽铆钉时，电荷杆仍然可以向下但无法向上(图1)。
第四. 断路器的正常电流选择要比电荷启动电流大1.5倍以上。
第五，为此改善电弧呼应控制，增加主电源接触器。电葫芦控制盒里没有主电源接触器。控制方向盘的紧急停止开关控制电源切断，但接触器，粘贴问题没有保护效果。添加主电源接触器后，控制方向盘的紧急停止开关控制其切断，可有效防止上山接触器无法分离而发生的事故。另外，根据tsgq 7015-2008起重机的定时检查规则，增加了相控时序保护装置。
First, cable-stayed suspension is strictly prohibited. Because the oblique pulling is because navigation line leans to one side, which may cause navigation line to break and be damaged.
Second, in order to prevent unrestricted position change, the upper limit and lower limit of the device for limiting fire occurrence will be fixed in place after appropriate adjustment.
For 3 or 5 lines, Class B is a common line. The terminal on the side of puthy road is close to the liz contactor above AC. If the terminal above AC of contactor falls off this position, in the opposite direction, when the elevator is inserted on the brake fracture, the electric nozzle can still be upward, but not downward. On the contrary, when the down jacket reaches the shielding rivet, the charge rod can still be downward but cannot be upward (fig. 1).
4. The normal current selection of circuit breaker is 1.5 times larger than the charge starting current.
Fifth, to improve arc echo control and add main power contactors. There is no main power contactor in the electric hoist control box. The emergency stop switch that controls the steering wheel controls the power cut-off, but the contactor and sticking problem have no protective effect. After the main power contactor is added, the emergency stop switch that controls the steering wheel controls its cut-off, which can effectively prevent the accident that the uphill contactor cannot be separated. In addition, according to the timing inspection rules of tsgq 7015-2008 crane, a phase control timing protection device is added.
