As an efficient construction equipment, self loading mixer trucks play an important role in fields such as construction and roads. Among them, the feeding arm is a key component responsible for lifting materials into the mixing tank. However, in practical use, sometimes there may be situations where the feeding arm cannot move, which directly affects the normal operation of the mixer truck. Below, I will introduce the common causes and corresponding solutions of the feeding arm failure of the self feeding mixer truck.
Common Causes Of Feeding Arm Malfunctions
- Hydraulic System Malfunction
The action of the feeding arm is usually driven by the hydraulic system. If there are leaks, oil pump damage, or hydraulic pipeline blockages in the hydraulic system, it can cause the feeding arm to malfunction.
- Electrical Control System Malfunction
The electrical control system of the mixer truck controls the action of the feeding arm. If the electrical components are damaged, the circuit contacts are poor, or there are errors in the control program, it may cause the feeding arm to be unable to move.
- Mechanical Component Damage
If the mechanical components of the feeding arm, such as bearings, gears, etc., are used for a long time or maintained improperly, they may be damaged by wear, fracture, etc., resulting in the inability of the arm to move.
- Material Blockage
During the mixing process, if the material is too viscous or contains large impurities, it may cause blockage inside the feeding arm, making it unable to move.
Solution
- Check the Hydraulic System
First, check the oil pump, hydraulic pipelines, valves, and other components of the hydraulic system to ensure that they are working properly and have no leaks. If damage or blockage is found, it should be replaced or cleaned in a timely manner.
Check the Electrical Control System
Check the wiring connections, electrical components, and control programs of the electrical control system. Ensure that the circuit connections are firm and the electrical components are undamaged, and recalibrate or update the control program to restore normal control functions.
Replace Mechanical Components
Damaged mechanical components such as bearings, gears, etc. should be replaced in a timely manner. During the replacement process, it is necessary to ensure that the model and specifications of the new components match those of the original components to ensure the normal operation of the feeding arm.
Cleaning Material Blockage
If the problem is caused by material blockage, the machine should be stopped for inspection and the blocked material should be cleaned. At the same time, attention should be paid to adjusting the material ratio and mixing process to avoid similar problems from happening again.
In addition to the specific solutions for the reasons mentioned above, it is also necessary to strengthen the daily maintenance and upkeep of the equipment. Regularly inspect all components of the equipment, promptly identify and address potential issues; At the same time, follow the user manual of the equipment to avoid malfunctions caused by misoperation.
In short, when the feeding arm of the self feeding mixer truck cannot move, the cause of the malfunction should be investigated first, and then corresponding solutions should be taken for handling. Timely maintenance and upkeep can ensure the normal operation of equipment, improve construction efficiency and quality.
