As a special truck for concrete transportation, the mixer truck is very important for daily maintenance. Therefore, to ensure the service life of the mixer truck, maintenance work must be done. If the maintenance and maintenance of the mixer is not in place, it will affect the performance and life of the mixer. The following Xiaobian explains to you about some knowledge about the maintenance and maintenance of the mixer.
1. First of all, for the newly purchased vehicles, the first use of about 50 hours, on the inspection of the bolt fastening situation. Including the tank head and reducer connection bolts, reducer base and the front connection bolts, tug base Connection bolts with the frame, connecting bolts for the subframe and the girder, etc. It is necessary to ensure regular inspections once a month.
2. Check whether the lubricant on the surface of the supporting roller and the raceway is dry before driving every day. It should be added in time to maintain a good lubrication effect. Check the oil level of the cooler and the reducer before the vehicle is started to ensure the oil level indicator. In the visual range; check the sealing condition of the hydraulic oil circuit, keep the hydraulic system clean and sealed, so as not to contaminate the system hydraulic oil with dust particles and moisture, resulting in the system can not work or damage.
3, at least once a month to clear the dirt on the roller and roller; through the nozzle on the roller, inject grease into the roller. Ensure that the drive shaft lubrication at least once a month.
4. The hydraulic system components have high precision. Especially the hydraulic pump of the mixer truck is easy to maintain, but it is very demanding. The hydraulic oil should be replaced periodically and run for 500 hours for the first time. After 2000 hours or at least once a year, the filter element should be replaced at the same time. When changing oil, the engine must be stopped, otherwise the hydraulic system will be damaged.
5. It is forbidden to arbitrarily weld and change the water tank to avoid heavy object impact; the water level display pipe and the filter should be replaced in time to avoid clogging, affecting the water level judgment; constantly check whether the various valve bodies are blocked or abnormal, and perform lubrication in time. In the environment where there is a possibility of ice formation, the water supply system must be drained to prevent the pipeline from freezing. Frequently check the system's tightness. The key part is to apply sealant to the pipeline.
Instructions for using the mixer truck:
First, before starting, you should carefully inspect the various parts of the mechanical system and confirm that it is good enough to start.
Second, before starting, the stirring lever should be placed in the "neutral" position.
Third, after the start, the stirring lever should be placed in the "unloading" position and the water in the cylinder should be drained.
Fourth, when loading, stirring rod should be placed in the "loading" position.
5. Before transport, the unloading tank must be fixed in the “traveling†position to prevent swinging.
6. When operating the joystick, stop at the “neutral†position before moving to the next position.
7. Do a good job of civilized construction. Excess materials in the barrel must not be allowed to fall. After the unloading, the mixing drum, feed trough, idler and other parts must be cleaned.
8. When the person enters the barrel to clear the agglomeration, the vehicle shall be turned off, the key of the switch shall be removed, and the peripherals shall be monitored.
Mixer car use matters needing attention
1. The pressure of the hydraulic system shall comply with the provisions in the instruction manual and shall not be arbitrarily adjusted. The oil quality and quantity of hydraulic oil should meet the original requirements.
2. Before the concrete mixer is loaded, the remaining water and debris in the mixing container should be drained. During the transportation, it should be kept turning to prevent the concrete from segregating. Before the Concrete Mixer Truck arrives at the site and unloads, it should first make the mixing drum rotate at 14-18 rpm for 1-2 minutes, and then reverse unloading. Before reversing, the mixer should be stopped without turning.
3. The ambient temperature is higher than +25 degrees Celsius. The duration of time from loading, transporting, and unloading shall not exceed 60 minutes. The ambient temperature shall be less than +25 degrees Celsius. The above time shall not exceed 90 minutes.
4. During winter construction, it should be ensured that: Check whether ice is formed before starting the machine; Carefully exclude residual water in the mixing bowl and the water supply system, turn off the water pump switch, and place the control handle in the “stop†position.
5. After the unloading at the construction site is completed, the hoppers, hoppers, unloading chutes, etc., shall be flushed with the hose provided with the mixer immediately to remove the sludge and concrete adhering to the vehicle body. On the way back to the mixing station, 150-200L of water should be injected into the mixing drum to clean the concrete residue on the wall and the blades.
6. After the end of each day's work, the driver shall be responsible for injecting fresh water into the mixing drum and rotating it at a high speed (14-18 rpm) for 5-10 minutes, and then drain the water to ensure that the drum is clean. When using high-pressure water to clean all parts of the mixer, care should be taken to avoid parts such as instruments and joysticks. The distance between the pressure water nozzle and the body paint surface must not be less than 40 cm.
7. When clearing the inside and outside of the mixing drum and the residual concrete slag pieces, and when the mechanics enter the drum for inspection and welding repair work, the vehicle engine must be shut down to stop the mixer drum completely from turning. During the work of the mechanics entering the cylinder, it must be ensured that the inside of the mixing cylinder is well ventilated, the air is fresh, there is no natural gas and no harmful dust, and the oxygen supply is sufficient (no pure oxygen must be used). The operator must have good insulation protection when operating in the barrel using a power tool.
8. When working, do not put your hand into the rotating mixing drum. Never stick your hand into the main discharge chute and lengthen the connecting part of the discharge chute to avoid accidents.
9. Check the wear condition of the mixing blades regularly and repair and renew them in time.
10. Implement all relevant safety practices. Concrete mixer truck drivers must undergo professional training.
