1. During winter construction of concrete feeding and mixing trucks, it is necessary to check for icing before starting up; At the end of work, carefully remove any remaining water in the mixing drum and water supply system, turn off the water pump switch, and place the control handle in the "stop" position.
2. When the concrete loading mixer truck unloads, if it finds that the water evaporates and the slump is too low to meet the user's needs, it can add water to the drum appropriately, and then rotate at a speed of 10-14r/min for 30 revolutions before unloading, so that the concrete is fully mixed.
3. During the unloaded operation of the concrete feeding mixer truck, the mixing drum must not stop rotating to avoid local collision of the raceway and supporting wheels caused by vibration, resulting in abnormal damage to the raceway and supporting wheels.
4. The water tank of the concrete feeding mixer truck should be filled frequently as a backup. Before adding water to the water tank, it is necessary to open the vent valve to release the air inside the tank; Open the air valve during flushing, and release the gas in the water tank after flushing or when it is stopped. When parking in winter, there should be no excess water in the water tank and water supply system to prevent freezing and cracking. The water tank should only be pressurized automatically when supplying water. Do not drive the concrete loading mixer truck on the road with the pressurized water tank.
We focus on producing a series of high-performance automatic loading mixer trucks
