Hoist has the following situation should immediately stop:

卷扬机设备虽不算娇贵的机器，但由于工作时长、使用年年限较长、操作不当等原因往往容易出现一些常见的故障。有的时候工程项目比较赶，所以即使出现了一些异常，很多操作人员也不会立即停机进行检修，等到工作告一段落在检查。这个无可厚非，但是如果您的卷扬机出现了以下故障，那就必须立即停机进行检查了。

The equipment is not a delicate machine, but because of the working hours, the use of years longer, improper operation and other reasons are often prone to some common fault. Compared to catch some project, so even if there are some exceptions, many operators will not immediately shut down for maintenance, when the work ended in check. This no ground for blame, but if your hoist appeared the following fault, it must immediately stop check.

1、控制电器故障

1, control the electrical fault

控制电器关键部件出现问题时，往往伴随着很大的异常噪音、对于这种情况要多听多看，不同部位的故障导致的噪音是有区别的，要根据故障所在部位采取不同的措施，在熟悉之后，分辨故障所在部位易如反掌。

Control key parts electrical appliances when problems arise, often accompanied by abnormal noise, great for this situation to hear and see more, leading to failure in different parts of the noise is different, different measures should be taken according to the fault location, fault in the familiar, resolution in location.

2、减速器故障

2, reducer fault

如果是减速器部分出了故障，要立刻停机操作，检查电机是否遵守了使用规则，使用前是否按说明添加、以及及时更换润滑油，或者轴承磨损严重等等情况，要对症下药，及时维修，减少意外情况的发生。有时一些小的故障往往会引发大的问题。

If the speed reducer is part of the fault, should immediately stop operation, check the motor's compliance with the rules for use, according to the instructions before use is added, and the timely replacement of oil, or bearing wear serious and so on, to an antidote against the disease, timely repair, reduce the occurrence of accidental circumstances. Sometimes some small failures often cause big problems.

3、电机故障

3, the motor fault

电机运行中出现响声时，应立即停止操作，然后检查电机各部位是否有损坏现象、是否单相运转、轴心错位等种种现象都会导致有异常响声。检查产品时，要多听多看，可以利用或根据故障响声特点，确定发出响声位置，寻找和检修故障。完整的检修有助于设备的保养和高效工作。

Noise appears in running motor, should immediately stop the operation, and then check all parts of motor is damaged phenomenon, whether single phase operation, axial dislocation phenomena will lead to abnormal noise. Check the product, to hear and see more, can use or according to the fault noise characteristics, determine the sound position, finding and troubleshooting. Complete maintenance contribute to the maintenance of equipment and efficient work.
