As a highly mechanized engineering equipment, mini excavator maintenance is very important. Reasonable maintenance can extend the service life of equipment and improve work efficiency. Below I will introduce in detail the maintenance methods of small excavators:
Regular inspection and maintenance Maintenance of a mini excavator requires regular comprehensive inspections. It mainly includes the following aspects:
(1) Check the working status of each component: including the normal operation of the engine, hydraulic system, traveling system, electrical system and other components, and deal with any problems in a timely manner.
(2) Check the oil level: Regularly check the levels of engine oil, hydraulic oil, transmission oil and other oils, and replenish them in time to avoid malfunctions caused by low oil levels.
(3) Cleaning and maintenance: Clean the surface of the machine regularly to remove accumulated soil and debris to avoid corrosion. At the same time, check the lubrication condition of each component and add lubricating grease appropriately.
(4) Fastener inspection: Carefully check whether the bolts, nuts and other fasteners at each connection part are loose and tighten them in time.
(5) Filter cleaning: Clean oil, air and other filters regularly to ensure the cleanliness of equipment operation.
Regular maintenance and repairs In order to ensure the working efficiency and service life of small excavators, regular overhaul and repairs are required, which mainly include:
(1) Regular overhaul: According to the manufacturer's recommended cycle, such as an overhaul every year or every two years, replace key parts. Overhaul can effectively extend the service life of equipment.
(2) Regular maintenance: According to the requirements of the maintenance manual, such as performing minor maintenance every 50-100 hours, checking the operation of each part, adjusting the tightness, etc.
(3) Repair and maintenance: During daily use, once a problem is discovered, repair and maintenance must be carried out in time. Including replacement of worn parts, repair of faults, etc.
In addition to regular maintenance, rational use and operation are also the key to extending the service life of small excavators:
(1) Reasonable use according to operating requirements: Do not exceed the load-bearing capacity and operating range of the equipment and avoid overload operation.
(2) Pay attention to the working environment: Try to avoid working in harsh environments, such as mud, high temperatures, strong winds and other extreme conditions.
(3) Reasonable operation: Operate by experienced operators, abide by safe operating procedures, and avoid sudden braking, sharp turns, etc.
(4) Shut down and rest: After a long period of operation, the machine should be shut down and rest appropriately, and then restart after the engine and hydraulic system have cooled down.
Professional maintenance and repair For some highly professional maintenance and repair work, it is best to be completed by a professional repair station authorized by the manufacturer, such as engine overhaul, hydraulic system repair, etc. This can not only ensure the quality of repairs, but also obtain relevant warranty services.
In general, the maintenance of small excavators needs to start from multiple levels such as daily inspection, regular maintenance, and rational use. Only in this way can the service life of the equipment be maximized and work efficiency and safety improved. If you have any questions, please feel free to consult professionals.
