Mine Winch's performance is very good, so its application in the market is also very extensive. Many users choose the Dispatch Winch when purchasing a winch, but they must operate according to the requirements when using it, otherwise it is easy to malfunction. In particular, the protection system of the winch is prone to problems, but the problem is usually the cause of the brake. Just replace it in time, you can.
There is a problem with Mine Winch, they are all found on the protection system. For example, brake shoe protection issues, safety circuits disappear, you have to change the brakes, other similar, but electrical components and hydraulic station components, which may be wrong, but not a big mistake, you must understand the system to be repaired. The deceleration point is on the depth indicator. Change the position of the upper and lower deceleration points and the travel switch.
Dispatch Winch, inverter fault, line fault, control program is generally no problem, can not be replaced, protection is no problem. The hydraulic station is not a hydraulic pump. In addition to the problem of the combustion pump, the problem with the hydraulic station is also a problem with the valve. For example, the valve is burned, or the adjustment position needs to be adjusted, and the tubing is leaking or blocked. Generally speaking, things will not be bad except for the bad parts. In short, if you want to solve this problem, you must understand the schematic.
Mine Winch's Dispatch Winch uses DC, AC cutting resistance, and the AC variable-frequency cutting resistance winch is the same. At present, the winch pressure adjustment method mainly uses an electro-hydraulic proportional valve for pressure regulation. That is, the electronic control system sends a control voltage or current to the proportional valve, and the control voltage (flow) is substantially linear with the system pressure. The greater the voltage (flow), the greater the pressure at the hydraulic station.
