Atlas of roadheader in North heavy mine

1. I have an electronic manual

2. Search the Internet library

3. Adjust the pressure of multi way valve.

4. This problem is not clearly stated. You should talk about the model. You can analyze the model. I think the problem you mentioned may be a normal phenomenon. Some roadheader's first operation (scraper conveyor) and walking are a pump. When you drive the conveyor, it will be slow to walk because the first operation is working. If it is the problem of hydraulic control valve, I'm afraid it will show more performance! Such as walking powerless, walking slowly and a move, because the slide valve jump liquid speed up operation!
