1. The continuous operation time of operation equipment shall not exceed 8h.
2. The capacity, quality and slump of delivered concrete shall meet the concrete industry standards and requirements.
3. The water tank should be filled up frequently in case of emergency. Before adding water to the water tank, it is necessary to turn on the air valve to let off the air in the tank; when flushing, turn on the air valve, and let off the air in the water tank when flushing is finished or stopped.
