Flat mouth mixer truck is a special type of vehicle used to transport concrete from the mixing plant to the construction site, and its mixing system requires long-term operation to maintain the freshness of the concrete. In order to ensure the long-term operation of the flat mixing truck and avoid strikes or losses caused by equipment failures, daily maintenance and upkeep operations are crucial. Here is the maintenance and upkeep guide for a flat mixer truck:

1. Regularly check and clean the mixing bucket

Cleaning the mixing bucket: After each transportation of concrete, the mixing bucket should be cleaned immediately. Long term accumulation of concrete in the mixing bucket can lead to concrete clumping, affecting the mixing process and possibly damaging the mixing bucket. Capable of using specialized high-pressure water guns and cleaning equipment to remove concrete residues from the mixing drum.

Cleaning cycle: It is recommended to thoroughly clean every 1-2 days or after each use to prevent the concrete from drying and adhering to the bucket wall. If the construction site is particularly messy or the concrete is particularly viscous, cleaning should be done more frequently.

Precautions during cleaning: Be careful of the internal components of the mixing bucket during cleaning to avoid high-pressure water spraying onto the electrical and hydraulic systems, causing damage.

2. View and maintain the hydraulic system

Hydraulic oil inspection: Regularly check the hydraulic oil level in the hydraulic system to ensure that the oil level meets the requirements. If the oil level is too low, it may cause unstable operation of the hydraulic system, affecting the operation function of the mixer truck.

Replacing hydraulic oil: Long term use of hydraulic oil can lead to contamination and oxidation, reducing the efficiency of the hydraulic system. It is recommended to replace hydraulic oil according to the frequency of use and the manufacturer's recommended cycle, usually every 6 months or 1000 hours.

Check the hydraulic pipelines: Check the pipelines, joints, and sealing rings of the hydraulic system for leakage, aging, or damage, and replace them if necessary to avoid hydraulic oil leakage.

Cleaning hydraulic filter: Regularly clean the filter element of the hydraulic system to avoid filter blockage, which may affect the movement of hydraulic oil and the normal operation of the system.

3. Check and maintain the engine

Regularly replace engine oil: Engine oil should be checked and replaced regularly. Generally, the engine oil needs to be replaced after every 1000-2000 hours of operation. The use of high-quality engine oil can effectively protect the engine and reduce wear and tear.

Air filter: The air filter needs to be cleaned or replaced regularly, especially in construction environments with high levels of dust. Dirty and clogged air filters can affect the engine's air intake, reduce engine power, and increase fuel consumption.

Fuel system inspection: Check if the fuel lines, pumps, and injectors are functioning properly to ensure proper fuel supply. Regularly replace the fuel filter to prevent impurities from entering the engine and causing damage.

Cooling system maintenance: Check the coolant level to ensure that there is no water leakage in the cooling system. If there is a lack or leakage of coolant, it may cause the engine to overheat and affect its operational function.

4. Check the brake system

Brake fluid inspection: Brake fluid needs to be checked regularly to ensure the normal operation of the brake system. Brake fluid should be maintained at the appropriate level and free of impurities. If the liquid level is too low, it should be added in a timely manner and checked for leaks.

Brake pad and brake disc inspection: Regularly check the wear condition of the brake pads to ensure that the thickness of the brake pads meets the requirements. When the brake pads are excessively worn, they should be replaced immediately to avoid affecting the braking effect.

Brake system testing: Conduct brake efficiency testing to ensure that the brake system responds sensitively and has strong braking force. Especially after long-term operation or in high-temperature environments, the brake system may experience a decline in function, which requires special attention.

5. Check the tires and wheels

Tire pressure: Regularly check the tire pressure to ensure that each tire is inflated to the manufacturer's recommended specification value. Excessive or insufficient tire pressure can affect the stability and control function of the vehicle.

Tire wear: Check the wear condition of the tire, especially the tread and sidewall, to ensure that there are no severe cracks, bulges, or other damages. Tires with severe wear and tear should be replaced in a timely manner.

Wheel hub inspection: Regularly inspect the wheel hub for cracks or deformations to ensure its firmness and integrity.

6. Check and maintain the electrical system

Battery inspection: Regularly check the voltage and liquid level of the battery to ensure that there is no leakage. Check if the battery connector is loose and remove any corrosive substances from the battery connector to ensure the normal operation of the battery.

Lighting and signal system: Check whether all electrical equipment such as lights, signal lights, and speakers are working properly to ensure safe travel.

Electrical circuit inspection: Check whether the electrical circuits and connectors are loose, aged, or broken, especially the electrical components controlled and operated by the hydraulic system, to ensure normal operation.

7. Maintenance of chassis and suspension system

Suspension system inspection: Regularly inspect the tension springs, shock absorbers, bearings, and other components of the suspension system to ensure that they are free of cracks, looseness, and wear. Especially in a chaotic construction environment, the suspension system is under significant pressure, so its operational status should be given special attention.

Chassis cleaning and smoothness: Adhere to chassis cleaning, especially the various components of the axles, steering system, and drive system, to avoid soil and sand entering and affecting the operation of the components. Regularly smooth the various moving parts of the chassis to reduce wear and extend its service life.

8. Regularly check the emission system

Exhaust system inspection: Check for leaks, corrosion, and other issues in the exhaust pipes. Blockage or leakage of the exhaust system can lead to a decrease in engine power, increased fuel consumption, and even affect environmental regulations.

Emission monitoring: For mixing trucks that comply with environmental regulations, the emission system should be regularly tested to ensure that the emissions comply with local environmental regulations.

9. Vehicle inspection and maintenance

Vehicle inspection: Regularly conduct a comprehensive inspection of the entire vehicle, checking whether the body, cab, doors and windows, exterior, etc. are intact. Ensure that all fasteners, bolts, hinges, and other components are securely fastened to prevent malfunctions or safety hazards caused by looseness.

Smooth all moving parts: Timely smooth key components such as transmission shaft, steering system, brake system, hydraulic system, etc., reduce wear and ensure smooth operation.

10. Avoid excessive loading

Load management: Overloading during transportation of flat mixer trucks can add burden to components such as the body, chassis, and tires, increase wear and tear, and lead to mechanical failures. Therefore, overloading operations should be avoided to ensure that the vehicle's carrying capacity is within a safe range.
