I believe that for a veteran driver with many years of truck experience, some simple faults in the car can be dealt with only by moving his fingers. But there are also some drivers who encounter problems when they encounter problems with the mixer, and they will inevitably be taken advantage of by entering the factory for maintenance. Today, Mixer Common has compiled a super practical checklist of common failures of mixer trucks, and there is always one that can come in handy.
Common faults of mixer truck
(1) The radiator does not turn or turns non-stop
Check whether the radiator insurance is damaged; if so, you need to replace the fuse;
Check whether the temperature control sensor plug of the radiator is damaged; if so, you need to replace the temperature control sensor plug;
Check whether the radiator fan motor is damaged; if so, replace the motor;
Check whether the line is open or virtual, if so, check and replace the line.
(2) Weak rotation of the tank
Check the condition of hydraulic oil, whether the oil is too dirty;
The throttle cable is too loose;
Check the amount of hydraulic oil. If the oil level is low, add hydraulic oil to the specified oil level;
Check whether the hydraulic pump pressure is too low.
(3) Abnormal sound of tugboat
Check the maintenance of the tug, check the tug and track surface for debris;
Check whether there is a gap between the tug and the track, and adjust the relative angle between the tug and the track;
Check whether the internal bearing is damaged;
Lack of butter.
(4) The mixing drum does not rotate
Check whether the safety pin of the controlled valve of the hydraulic pump is broken;
The ball head bolt of the manual valve connecting the tie rod is loose or lost;
Check whether the hydraulic oil is seriously insufficient;
The filter element is clogged and the oil absorption is not smooth;
The reducer is damaged;
The hydraulic pump is damaged;
The hydraulic motor is damaged.
(5) The rear joystick is heavy
Lack of butter on the rod bracket;
Whether the connecting ball is loose.
(6) The indoor controller handle operation is heavy
Check whether the indoor controller cable is stuck and the angle is too large;
Check whether the cable sheath is worn or not;
Check whether the limit nut is loose.
(7) Abnormal sound of hydraulic pump
Check whether the hydraulic oil is dirty and whether the radiator needle has changed. If it is close to the red area, please replace the hydraulic oil and filter immediately;
Check whether the hydraulic oil tank is short of oil;
Check if there is air in the system, hold the high-pressure oil pipe with your hand to check if there is intermittent tremor, if there is tremor, give up processing;
Check if the oil inlet pipe is blocked;
If the internal leakage of the oil pump is too large, repair it;
Check if the hydraulic system charge relief valve is blocked, remove it and check.
(8) Abnormal noise of reducer
Check whether the bolts between the main plate and the tank flange are loose;
Check whether the main plate bearing of the reducer is damaged or has intermittent noise;
Check whether the reducer is abnormal due to lack of oil, and if it is missing, supplement it;
Check whether the output shaft gear is broken;
Check whether the reducer is deteriorated and replace it.
(9) Abnormal sound of drive shaft
Check whether the connecting bolts at both ends of the drive shaft are loose;
Check whether the installation angle of the drive shaft is too large;
Check whether the spline and universal joint bearings lack grease lubrication.
(10) The mixing drum can only run in one direction
Check whether the high pressure relief valve is blocked;
Check whether the shuttle valve is stuck.
(11) The flushing waterway cannot be used
Check whether the air pressure is sufficient;
Check whether the water tank is leaking.
The above is all about the common faults of the mixer truck. When the mixer truck encounters problems, you can refer to the corresponding solutions to solve it.
