上海华诚二手挖掘机市场 / 2024-09-14

  In the previous issue, we introduced the important structural assemblies and accessories of excavators. Today, we will introduce the consumable parts and maintenance accessories of excavators. The large wear and tear of excavators in daily use and the wear load will bring great pressure and accessories wear. If you work in the city or the surrounding areas, if the wear is excessive, you can buy it nearby. It is convenient to replace and you can change the model. If you are far away from the city, you need to keep several consumable parts on hand to avoid unexpected delays.

  1. Bucket teeth

  The bucket teeth are installed at the front of the bucket and directly contact rocks, soil, sand and gravel. The temperature and contact wear and pressure of materials during long-term work make the bucket one of the most stressful and wear-prone accessories in the entire excavator equipment. However, it is cheap and easy to replace and install.

  2. Bucket tooth plate

  The bucket tooth plate is installed on both sides of the bucket. Its main function is to cut off the materials in the working area. The wear degree is lower than that of the bucket teeth in soil work, but the wear is aggravated or deformation and cracks are caused when working with hard objects or high pressure. It is cheap and easy to replace. Users can always keep some bucket tooth plates on hand.

  3. Tracks

  The tracks of excavators mainly support the movement of the entire excavator equipment in various environments. The wear of different types of tracks varies greatly. In soil and wetland environments, the service life does not need to be replaced for 5-10 years, but in rock or hard geological environments, the service life will be greatly shortened, and the degree of wear of different moving distances and working moving frequencies is also quite different. Moreover, corrosion wear will be further aggravated in environments such as seawater.

  4. Hydraulic oil seals

  Commonly used in cylinders and hydraulic oil pipes, hydraulic oil pipe oil seals are cheap and easy to replace. It is a very common job to replace hydraulic oil seals for oil pipes with high pressure. A complete set of oil seals can be purchased in many excavator parts stores, and the versatility of hydraulic oil seals can be used in many parts of excavators. It can be said that this is a must-buy. The oil cylinder oil seal requires professional technicians to replace the model. The oil cylinder is heavy. If the surface of the oil cylinder is worn when exposed to the working environment, it will cause great damage to the oil seal. At that time, the oil cylinder and the oil seal need to be replaced at the same time. If there is no professional technician, we do not recommend that individuals replace it. At present, it is understood that there are many accidents when replacing the hydraulic cylinder oil seal.


  5. Pins and bushings

  Mainly connected with movable joints such as booms, dippers, and buckets, they bear huge pressure in daily use and are less worn by daily grease filling. However, with working time and external environment, wear is inevitable, causing shaking of the connection parts, displacement, loss of precision of the excavator or increased abnormal noise. Daily maintenance can greatly extend the service life. Replacement is not complicated but dangerous. The entire boom or dipper needs to be dismantled and replaced. It is recommended to replace the original pins and bushings. The service life of inferior products is extreme.


  For wearing parts, Tiedou used excavator sales network provides full support. When purchasing a used excavator, we will provide 2 sets of wearing parts commonly used for the entire equipment to ensure daily use. For parts involving more dangerous parts, we provide accessories but users need to ask professional technical engineers to replace them to avoid product accidents.
