The Hitachi ZAX200 support wheel is one of the important chassis components of the Hitachi ZAX200 series excavator. Here are some specific information about it: structural characteristics Wheel body: usually forged from high-strength alloy steel, processed through quenching and medium frequency quenching processes to ensure wear resistance and compressive bearing capacity, capable of withstanding the weight of excavators and the impact force during operation. Wheel axle: Generally subjected to tempering and high-frequency quenching treatment, it has stronger toughness and can ensure that it is not easily deformed or broken during long-term operation. Shaft sleeve: Double metal bushings are commonly used, which can effectively reduce the temperature inside the bore during long-term walking, reduce wear, and extend the service life of the supporting wheel. Sealing device: using Ding Qing sealing ring, high aluminum mirror floating oil seal and hyperbolic gear lubricating oil to ensure low-temperature sealing performance and low-temperature lubrication, preventing lubricating oil leakage and external impurities from entering the interior of the supporting wheel. The working principle is similar to other excavator support wheels. The Hitachi ZAX200 support wheel is installed below the excavator track. During operation, it rotates with the movement of the track, transmitting the weight of the excavator to the ground through the track. At the same time, the support wheels can also reduce the frictional resistance between the tracks and the ground to a certain extent, allowing the excavator to travel and operate smoothly.

The supporting wheel plays a role in supporting weight: it bears most of the weight of the excavator, allowing it to stand stably on different terrains and preventing the excavator from sinking into soft ground due to excessive weight. Disperse pressure: evenly distribute the weight of the excavator on the tracks to reduce local pressure between the tracks and the ground, thereby reducing track wear and damage to the ground. Ensure driving stability: During the excavator's movement, the support wheels can maintain the normal operation of the tracks, making the excavator travel more smoothly and avoiding phenomena such as shaking and deviation. Daily maintenance inspection: Before and after each use of the excavator, the supporting wheels should be inspected to check for wear, cracks, deformation, and other conditions on the wheel body. The sealing rings should be checked for integrity and oil leakage. Cleaning and maintenance: Regularly clean the soil, sand, and other impurities on the surface of the supporting wheel to prevent them from entering the interior of the supporting wheel and affecting its normal operation. At the same time, it is necessary to clean the tracks and chassis components around the support wheels to maintain a clean working environment. Lubrication and maintenance: Lubricate and maintain the supporting wheel according to the specified time and requirements, add an appropriate amount of lubricating oil, ensure good lubrication between the various components of the supporting wheel, and reduce wear. Market price: Generally ranging from over 200 yuan to over 400 yuan. For example, the support wheel suitable for Hitachi ZAX200-3 excavator sold by Quanzhou Futeng Machinery Equipment Co., Ltd. is priced at 270 yuan per piece, while the Hitachi EX200 support wheel sold by Jining Xinju Engineering Machinery Co., Ltd. is relatively expensive.
