Maintenance Tips for Your Fully Automatic Self-Loading Concrete Mixer Truck

Automatic self-loading concrete mixing transport truck is a precision equipment that integrates functions of material loading, metering, mixing and transportation. Maintenance is an important link for ensuring the efficient and stable operation of equipment, extending the service life of equipment, and reducing operating costs. This paper will elaborate on the point of maintenance of automatic self-loading concrete mixing truck in many aspects, so as to provide reference for equipment management personnel.

Inspection and maintenance on a daily basis

Routine inspections are a vital component of preventative maintenance, and they need to be carried out before and after each job; separating potential problems quickly and ensuring that minor faults do not become major issues.

Check hydraulic system: check whether the position of the hydraulic tank is up to the level, observe whether the hydraulic pipeline and the jointer have leaks; Pay attention to listen carefully whether the hydraulic pump acts abnormal noise. The hydraulic system is one of the important core systems of the automatic self-feeding stirring transport vehicle, and the cleanliness and oil level of the hydraulic oil directly affect the operational performance of the hydraulic system.

The electrical system can inspect whether the battery terminal is firm and has corrosion; it can also check whether the insulation layer of each electrical line is intact and whether there is damage or wear; All the indicators, gauges and control buttons should be in good condition. Electrical system stabilization is a prerequisite for the normal operation of the vehicle.

Tire inspection: The tire pressure meets the standard, and check whether the tire surface has abnormal conditions such as wear, cuts or bulging. In turn, abnormal tire states will influence the vehicle turning safety and oil saving.

Inspection of the mixing drum and discharge system: visually check whether the mixing drum has concrete residue, whether the discharge port is smooth, and whether the mixing blade has obvious wear and deformation. This residual concrete will often decrease mixing efficiency and even compromise the quality of the concrete.

Inspection of Safety Devices: Observe whether the braking system, steering system, lighting system, alarm device and other safety devices such as brake lights and warning lights are operating normally to ensure the safety of personnel and the surrounding environment.

Hydraulic system: Critical system maintenance

The hydraulic system maintenance is the important issue about the maintenance of automatic self-loading concrete mixing transporter.

Regularly replace hydraulic oil and filter: According to the requirements of the manufacturer to replace hydraulic oil and filter, to keep hydraulic oil clean, prevent impurities from wearing hydraulic components, and affecting system operation. After one period of use, change the hydraulic oil that meets the requirements of the equipment.

Maintenance and inspection on hydraulic components: Halting maintenance, frequently inspecting key components of hydraulic pumps, hydraulic motors, hydraulic cylinders, control valves, and observing whether there is abnormal vibration, noise, leakage, etc. Replacing worn or damaged seals in time to avoid leaking hydraulic oil.

Cleaning of hydraulic system: When maintained the hydraulic system, we should try avoid the sand or harmful impurity come in the system. Open or repair hydraulic components must be disassembled in a clean environment, and the oil port should be timely seal, to avoid pollution.

ITR.Subsystem = 'Electrical system'

The stable operation of electric system is a prerequisite for the automatic self-feeding stirring transport vehicle to perform its automatic function.

Maintenance of battery: regularly check the battery liquid level, maintain the surface of the battery clean, get rid of the corrosion around the terminal, apply protective agent to the terminal of the battery (apply a layer of Vaseline), to ensure that the electrical connection smooth.

Line inspection and maintenance: The fixed condition of the cable bundle should be checked frequently, so as to prevent loosening or friction damage of the insulation layer. Age-related or damaged wires must be timely replaced to avoid short circuit or open circuit failure.

Maintenance of sensor and control system: Regularly verify the working condition of the sensor to reduce the measurement deviation. Dust or dirt can affect sensor performance, so prevent it by cleaning the sensor surface. It is advisable that the control system software be updated or maintained when necessary to guarantee stable operation.

Critical system maintenance : mixing system

Concrete mixing quality and efficiency is directly related to the maintenance of mixing system.

Cleaning of mixing drum in time: When the operation is completed, the concrete residue in the mixing drum must be cleaned, cleaned with high-pressure water gun or manually cleaned in time, otherwise, after the concrete hardening, it will be difficult to remove, affect mixing efficiency and concrete quality.

Check the mixing blade and do the maintenance: regularly check the wear of the mixing blade, and timely replace seriously worn blades, to ensure the mixing effect. Verify that the gap between the blade and the cylinder wall is normal.

The driving mechanism of the mixing drum should be maintained: frequently lubricating the gears, bearing and other components of the driving mechanism of the mixing drum, reduce wear, extend the service life. Look for loose connection bolts of the drive mechanism.

Maintainance and Maintenance Schedule

Daily maintenance is just part of the project, and according to the manufacturer's requirements to formulate maintenance and maintenance plans, and strict implementation. Routine maintenance generally involves more comprehensive inspection, lubrication, tightening and replacement of wearing parts. For example, Change engine oil and filters (engine air filter, fuel filter) regularly; Lubricate the lubrication points For each moving part of the vehicle; Check and adjust the braking system and steering system of the vehicle; And a full safety check for the vehicle.

Does that work well for you? Troubleshooting and FAQs

Due to the inherent structure of fully automatic self-feeding concrete mixing truck, even if such equipment is well maintained, there are still a lot of failures during use. Device management personnel to understand the common failure types and more troubleshooting methods The common failures of hydraulic systems include oil pump damage, oil pipe leakage, control valve failure, etc. Common faults of electrical system: line short circuit, sensor failure, control unit failure, etc. The mixing system has common faults including mixing cylinder can not turn. The fault that cannot be solved by itself, maintenance should be timely, do not blindly disassemble.

conclusion

The maintenance of automatic self-loading concrete mixing truck is a systematic work, which requires the high attention and careful implementation of equipment management personnel. It can effectively ensure the good operation of the equipment through daily inspection, key system maintenance and regular maintenance, reduce the failure rate, extend the service life, improve the working efficiency and ultimately provide a strong guarantee for the smooth completion of the project. Along with this, the standard maintenance can also reduce the operation cost and improve the overall economic benefits of the equipment.
