Check the use of the elevator, let's take a look with the editor below!
In the use of machinery such as aerial lifts, there must be more precautions in use. These precautions not only help to improve the effect of safe use, but also extend the life of the aerial platform lift truck. Here, we are talking about the electrical inspections of aerial lifts before they are used.
When doing electrical inspection, it is necessary to install two standard sections using lifting equipment before commissioning. After the standard sections have been installed and debugged, perform the following debugging. 1. When using a ground resistance tester to measure the steel structure of an aerial platform truck, or when using a metal casing of an electrical device for ground resistance processing, one of the data we should pay attention to is that the ground resistance should not be exceeded. only when it is used within such a range of normal use, can the grounding resistance play a more normal use effect. 2. If we use a 500V megohmmeter to measure the motor and the electrical resistance to ground of the electrical components, the normal value used must be in. once it exceeds this use standard, there will be problems with the use of electrical equipment, shortening high-altitude operations. The service life of the lift truck. 3. For the control switches used on aerial lifts, during inspection, the doors on each hanging cage should be opened, so that once the protection switch of the broken rope, or the upper and lower limit switches and limit switches can be played, Good use effect. Later, the electrical inspection of the aerial lift, whether before or during the use of the aerial lift, must be properly checked to ensure the normal use of the aerial lift.
