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。 The reason for the failure of the hand-lever gourd is that there are two kinds of reasons for failure in the use of the gourd. One is the neglect of maintenance and the other is improper operation. Today, we are not saying what caused the accident, but what we should do about it. 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。 There are three common types of malfunctions that can be used in the use of handlettes: lifting chains and jumping. Hook decoupling; The brake doesn't wait. Let's take a look at how we can solve this when this happens. 一 a 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。 Hoisting and stopping of lifting chain; If the chain has this condition, it indicates that its lubrication is not done well. Strictly speaking, the lubrication of the chain should be checked before and after the operation of the handlettes, and if the lubrication is not in place, the lubricant should be applied in time. Also, in daily maintenance, you need to lubricate the lifting chain. 二 The second 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。 Hook decoupling; There is a safety tongue on the hook for protection, and there is usually no decoupling. However, when heavy wobbles occur during heavy lifting, or when the tongue is lost, it causes a decoupling failure. So, in order to avoid sudden weight suddenly from falling apart, it should be forbidden to be under heavy weights and surrounding activities. When the decoupling occurs, it is necessary to check whether the tongue of the hook or the hanger has an abnormality. 三 three 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。 Brakes; When the brake is not flexible, stop the operation in time, investigate its cause, and find a professional to solve it. Before solving the problem, it is forbidden to work with the hand-lever gourd.
