1. When the mucking loader is running with no load, the noise of the driver's operating position shall not exceed 90dB(A).
2. For the mucking loader with cable winding device, the cable winding and unwinding should be synchronized with the operation of the mucking loader.
3. After the hydraulic system reaches thermal equilibrium, the oil temperature shall not be higher than 75°C.
4. The mucking loader forwards, backwards, turns left and right, lifts and turns of the picking or excavating mechanism, the lift of the steering transport mechanism of the steering mechanism, and the movement of the scraper chain should be flexible, stable and free from jams.
5. The hydraulic circuit for the left and right steering of the mucking loader and the lowering of the boom should be equipped with a speed control device, and the operating mechanism should be flexible, accurate, convenient, and reliable, and have obvious control signs. The operating force of the joystick is:
a. It is not more than 40N to be manipulated by wrist.
b. Operate with a single arm not more than 150N.
6. The hydraulic steering mechanism of the mucking loader should have sufficient sensitivity and adjustability.
