手扳葫芦若在使用时发生故障，其原因无外乎有两种，其一是疏于维护，其二便是操作不当。今天，我们不是来说造成事故原因的，而是来分析出现故障后，我们应该怎么解决。

Lever hoist if failure occurs when using, its reason into two categories, one is to neglect, second is improper operation. Today, we are not causing the cause of the accident, but rather to analyze failure, we should how to solve.

手扳葫芦在使用时，常见性的故障有三种，它们分别是：起重链条卡阻、跳动；吊钩脱钩；刹车不灵等。下面便让我们来看下当出现这种情况时，我们应如何来解决。

Lever hoist in use, there are three kinds of common fault, they respectively are: lifting chain jam, beat; Hook decoupling; Brakes, etc. Then let's look at the below when this happens, we should how to solve.

一起重链条卡阻、跳动；起重链条若出现这种状况，则表明它的润滑工作没有做好。严格来说，在使用手扳葫芦工作的前后，都需要检查链条的润滑，如若润滑不到位，则需及时涂抹润滑油。还有，在日常的维护工作中，也需要对起重链条做好润滑处理。

Heavy chain jam, beat together; Lifting chain, if appear this kind of situation, indicates its lubrication didn't work well. Strictly speaking, in the use of lever hoist before and after work, need to check the chain lubrication, if the lubrication is not in place, is the grease in a timely manner. Also, in the daily maintenance work, also need to keep the lubrication of lifting chain processing.

二吊钩脱钩；吊钩上有安全舌片进行保护，一般不会出现脱钩现象。然而当在吊重时出现剧烈的晃动，或舌片丢失时，则会造成脱钩故障。所以，为了避免突然重物突然脱钩自坠造成危险，应禁止任何人在重物下面及周围活动。当出现脱钩时，需检查吊钩的舌片或吊装具是否出现了异常。

Second hook decoupling; Have safety hook tongue, general won't appear of decoupling. However, when there was a severe shaking in hoisting, or loss of tongue, can cause decoupling fault. So, in order to avoid sudden dangerous decoupling from the pendant, suddenly the weight should be no one under the weights and the surrounding activity. When a decoupling, need to check the tongue or lifting hook appeared abnormal.

三刹车不灵；刹车不灵活时，应及时停止操作，究其原因，并找专业的人士解决。在为解决前，禁止使用手扳葫芦工作。

Three bad brakes; When the brake is not flexible, should in time to stop operation, investigate its reason, and find the professionals to solve. Before to solve the problem, it is prohibited to use lever hoist.
