This series product winch structure type has the characteristics of compact, light weight, very light, beautiful and generous appearance design, and has the characteristics of good safety factor, high efficiency, large starting torque, good reliability of low speed, low noise, reliable practical operation, etc.. Application scope:
1. Rescue and road clearance;
2. Construction machinery; 3. Mining machinery; 4. Forestry division;
5. Oil industry
Frequency conversion winch frequency conversion governor common fault, also common fault line, management procedures generally no problem, you can not change, maintenance is no problem. The hydraulic station, not the hydraulic pump, except for the burning of the pump, what is the problem of the hydraulic station is the problem of the valve, for example, the valve burned, or the adjustment of the position must be adjusted, the oil pipeline is leaking or blocked. That article usually won't break unless it's broken. In short, if you want to fix this thing, you need to know the schematics.
Mine winch to use direct current, ac cutting resistor, ac frequency conversion type cutting resistor winch hydraulic station pressure regulation are all the same. At present, most of the pressure regulating methods of winch are hydraulic push rod proportional valve. That is, the electronic control system comes out of a control voltage or current to the proportional valve, the control voltage (flow) and the pressure of the system software is basically linear, the greater the voltage (flow), the greater the working pressure of the hydraulic station.
