Mixer truck is a kind of heavy mechanical equipment often used in engineering construction projects, and it is also one of the more common equipment in the market. If we neglect the maintenance and management of the mixer truck during its use, it is likely to aggravate the damage to the equipment in the later stage. When the loss increases, the failure rate will also increase, which will not only affect the service life of the equipment, but also bring potential safety hazards.
As the managers and users of mixing trucks, some people take up their posts after a few days of training. They lack certain post professional knowledge and equipment maintenance knowledge. When purchasing accessories and selecting accessories for installation, because the selected accessories are of poor quality, if installed on better equipment, it will reduce the efficiency of the equipment and may cause damage to the equipment for a long time.
Before starting up every day, check whether the lubricating oil on the joint surface of roller and raceway is dry, and supplement it in time to maintain good lubrication effect. Before starting the vehicle every time, check the oil level of the cooler and reducer to ensure that the oil level indication is in sight. Check the sealing condition of the hydraulic oil circuit, and keep the hydraulic system clean and sealed, so as to prevent dust particles and water from polluting the hydraulic oil of the system, causing the system to fail to work normally or damage.
Clean dirt on rollers and raceways at least once a month; Fill the roller with grease through the grease nipple on the roller. Ensure that the drive shaft is lubricated at least once a month.
High accuracy of hydraulic system components. In particular, the hydraulic pump of the mixer truck is easy to maintain, but the requirements are very high. The hydraulic oil should be replaced regularly. The filter element should be replaced at the same time after the first 500 hours of operation or at least once a year after 2000 hours. Or the engine must be stopped when changing the oil, otherwise the hydraulic system will be damaged.
It is forbidden to weld or refit the water tank at will to avoid the impact of heavy objects; Replace the water level display pipe and filter screen in time to avoid blocking and affecting the judgment of water level; Regularly check whether various valve bodies are blocked or abnormal, and lubricate them in time; When used in an environment that is likely to freeze, the water supply system must be emptied and stored to prevent pipeline icing; Regularly check the tightness of the system and apply sealant on the pipes at key parts.
In the ready-made operation of the full-automatic mixer, it may be because the site environment is complex and the site location is remote. If the mixer truck has serious problems at this time, it may delay the timely maintenance of the mixer truck and cause some damage. Moreover, some management companies do not pay enough attention to the after-sales maintenance of mixer trucks. They may not be professional enough in the later maintenance, and the maintenance measures and records are not very perfect. Therefore, in the protection and maintenance of mixer truck, we should pay attention to the cultivation of personnel quality and knowledge. When maintaining the mixer truck, do not be careless, and you must follow the relevant procedures.
