Matters needing attention
The concrete mixer should be set in a flat position, and the front and rear axles should be padded with wood above, so that the tires can be placed very high and overhead, so as to avoid moving when starting.
Concrete mixer should prevent secondary leakage. After turning on the power supply before going to work, it must be carefully checked, and it can only be used after the empty test run is qualified. During the trial operation, check whether the speed of the mixing drum is appropriate. In general, the speed of an empty car is 2~3 revolutions faster than that of a car (after loading). If the difference is large, the ratio of the moving wheel to the driving wheel should be adjusted.
Check whether the transmission clutch and brake are flexible and reliable, whether the wire rope is damaged, whether the track pulley is in good condition, whether there are obstacles around, and the lubrication of each part.
