Problems solved by technology

[0005] In the case of heavy-duty climbing, the car is in a low-gear running state, and it is usually easy to lose gear due to the overload of the gearbox, which poses a great safety hazard
The normally open low-grade solenoid valve solves the out-of-gear problem, but using the low-grade solenoid valve to normally open at this time will cause the solenoid valve to overheat, which will cause fatal damage to the self-life of the solenoid valve
