As the saying goes, mixers are repaired at three points and seven points, and maintenance is especially important. This time, we will introduce to you in detail in three parts: inspection before leaving the vehicle, maintenance during the loading and unloading process, and precautions during transportation.
The mixer truck is most afraid of the tank not turning on the road. The concrete can't be stopped for more than 2 hours, and the concrete above C40 level can't be stopped on the road. After the car starts, let the jar rotate at a low speed, check the tire tread, tire pressure, etc. around the car, check whether stones, nails or the like are stuck in the tire, and clean it in time.
Including the connecting bolts of the reducer and the tank, the fixing bolts of the reducer base, the connecting bolts, and the U-shaped bolts. Regular maintenance must be done in daily operation. Check whether the new car is loose before leaving the factory. The first tightening cycle is the first to use Weekly, follow-up inspection and tightening once a month to prevent accidents.
Including reducer gear oil, hydraulic oil in the hydraulic system, engine oil, etc., if it is missing, it will cause wear on related components and affect the overall performance of the car. It is recommended to replace it after working for 100 hours for the first time, and every 1000 hours thereafter (at least once a year).
The radiator is equivalent to the breathing system of the car. Once the "breathing" is not smooth, it will cause the engine to overheat and cause problems such as cylinder explosion. Therefore, it is necessary to regularly check and replace the filter element in daily work. It can be replaced at the same time as the maintenance of the hydraulic system. Replace the filter element when the pointer is in the red area, and replace it at least once a year.
Transmission shafts, raceways, tugs, main groove shafts, joysticks and other components should be guaranteed to be filled with butter once a month to reduce the wear of key components and thereby extend the service life.
Since most of the mixer trucks are parked in the open, there may be sundries, leaves and other debris in the tank, which will affect the quality of the concrete if not discharged.
Let the concrete be fully mixed. If necessary, add some water to make the concrete more evenly mixed and facilitate unloading.
Because the small stones scattered during loading are easy to solidify on the inside and outside of the hopper and the chute, which affects the use and appearance.
Turn must be slow. Decelerate and reduce gear ahead of time before entering the bend. Observe whether the jar is turning through the rearview mirror at any time, and adjust the speed as slowly as possible. When the road conditions are not good, the low-speed gear should be passed, the uphill gear should be reduced in advance, and the start should be smooth. At the same time, it is best to speed up the speed of the tank to prevent the concrete from flowing out. Never downhill when heavy vehicles are in neutral. When turning downhill, decelerate ahead of time and then downshift to slow down. Finally, we must pay attention to the problem of height limitation. The road conditions on the construction site are complicated, and we must be careful of trees, etc., especially to prevent the wires from being scratched.
In recent years, the commercial and mixed market has been booming, and concrete mixer trucks have become a common vehicle. At the same time, it is also one of the tools to bring considerable benefits to our customers and friends. With continuous income, maintenance and protection in daily operation is especially critical. With inspection and maintenance before leaving the car, careful maintenance during loading and unloading, and standard operation during transportation, we will be farther away from danger and closer to safety; farther away from wear and tear and closer to revenue.
