Some of the owners of self-feeding mixer trucks who come into the site for maintenance when encountering problems will inevitably be the enemy. Today, Xiao Bian has compiled a super practical list of common failures of mixing trucks. There is always one that can be used.
1. The radiator does not turn or does not stop
Check whether the radiator fuse is damaged; If yes, replace the fuse;
Check whether the radiator temperature control sensor plug is damaged; If yes, replace the temperature control sensor plug;
Check whether the radiator fan motor is damaged; If yes, replace the motor;
Check the circuit for open circuit or virtual connection. If yes, check and replace the circuit.
2. Can body rotation is weak
Check the hydraulic oil status to see if the oil is too dirty;
The accelerator cable is too loose;
Check the hydraulic oil level. If the oil level is low, add hydraulic oil to the specified level;
Check whether the hydraulic pump pressure is too low.
3. Abnormal noise of tugboat
Check the maintenance of the tugboat and check whether there are sundries on the tugboat and track surface;
Check whether there is a gap between the tugboat and the rail, and adjust the relevant angle between the tugboat and the rail surface;
Check whether the internal bearing is damaged;
Lack of butter.
4. Mixing drum does not rotate
Check whether the safety pin of the controlled valve of the hydraulic pump is broken;
The ball stud of the connecting rod of the manual control valve is loose or missing;
Check whether the hydraulic oil is seriously insufficient;
The filter element is blocked and the oil absorption is not smooth;
The reducer is damaged;
The hydraulic pump is damaged;
The hydraulic motor is damaged.
5. Rear joystick weight
The pull rod bracket is lack of grease;
Check whether the ball joint is loose.
6. Indoor controller handle operation is heavy
Check whether the cable of indoor controller is stuck and whether the angle is too large;
Check whether the cable sheath is worn;
Check whether the limit nut is loose.
The inspection points of common failures of practical mixer trucks are explained in six aspects. If you have any questions, please come to our website http://www.zkzsljbc.com Ask!
