concrete mixer Precautions

1, the hydraulic system pressure should be consistent with the operating instructions shall not be adjusted. Hydraulic oil and fuel oil shall comply with the original requirements.
2, Stationary conacrete plant, before mixing tube drained residual water and debris. During transport to keep the rotation, to prevent segregation of concrete. Concrete mixer truck access to the site and unloading should be preceded by the mixing drum at full speed to 14-18 rev / min rotation for 1-2 minutes, then invert discharge. Reversal, you should not turn the mixing tube parked.
3, the ambient temperature is above +25 degrees Celsius, from the loading, transport, unloading duration to not more than 60 minutes, the ambient temperature is lower than +25 degrees Celsius, batch mixing plant not exceed 90 minutes.
4, winter construction, you should make sure: check before starting the icing; work when mixed carefully excluded from the barrel and residual water within the water supply system, turn off the pump switch, the control handle to the "stop" position.
5, after unloading at the construction site, immediately rinse with a hose that comes mixer into the hopper, the hopper, discharge chute, etc., adhere to the clear and concrete sludge throughout the body. In return mixing station on the way, mixing tube should inject 150 --- 200L water to clean the cylinder wall and the blade bonded concrete residue.
