Why does Crane Happen Header Phenomenon

• event Nov 12, 2016

Did you meet the phenomenon of the summit in the process of using crane. In fact a lot of people have asked this problem,it mainly has several aspects of reasons for this:

The first is restrictor itself. We all know that in the overhead cranes, restrictor plays a very important role. It is the main component to control the crane hook, and carry out the run up and down. If in the usual work we haven't check carefully, the restrictor joint will easily happen adhesion. Once this kind of phenomenon come into being, restrictor will lose its effect. It is conceivable that it will inevitably cause hidden trouble of personal and property safety .

The second is the neglect of staff operating. At the time of installation, they forget the order of the controller for the corresponding modulation, then stop contact will exist hidden trouble and happen header. If there is no problem in the installation, we should also pay attention to in the process of using. If we ignore these, that we may mistakenly put down as a rise in operation, it will also make limiter failure. If in the process, we are not to timely launch emergency driving switch, then it will appear the phenomenon of the summit.

In addition, there are two situations that also prone to header phenomenon. One is that device is used for a relatively long time. The long period of use, inevitably will be loose in the equipment parts, such as the screw on the limiter, so that the contact blocks are unable to come into contact with the stopper, which can lead to the phenomenon of the summit. The other one is the equipment has long age, when there is no regular check for it, restrictor will also has a lot of hidden trouble.
