Heavy steering

When this problems appears, we can use the troubleshooting method to check its problems. There are several common reasons:

1. Check the pilot pressure value of the self loading concrete mixer when it is stopped. The normal pilot pressure value should be no less than 2.2MPA at idling speed and no higher than 5MPA at high speed. If it is abnormal, the cause of the heavy steering is that the pressure value is different.

Solution: Use a professional disassembly tool to loosen the overflow valve nut. Then if the pilot pressure value is too small, increase the pilot pressure value clockwise, if the pressure value is too small, go counterclockwise.

2. If the pilot pressure value is normal, then continue to check the pipeline connection of the self loading mixer to see if there is any leakage, whether the pipeline joint is obstructed, and whether the hydraulic cylinder has internal leakage.

The failure of driving device

The working environment of self loading mixer is harsh and it is necessary to prevent the dirty cement sand from entering the hydraulic system. The hydraulic oil should be replaced regularly according to the requirements of the user manual. Once the hydraulic oil is found to be mixed with water or sand during the inspection, it is necessary to stop the machine immediately to clean the hydraulic system and replace the hydraulic oil.

The hydraulic oil radiator of the self loading concrete mixer should be cleaned regularly to prevent the radiator from being blocked by cement. Check whether the electric fan of the radiator is running normally to prevent the hydraulic oil temperature from exceeding the standard.

The universal rotating part is the part with frequent failures. Grease should be filled on time, and the wear condition should be checked frequently. The operator should have a spare cardan shaft assembly to ensure that it can resume work within tens of minutes in the event of a failure.
