Excavators - Xuzhou Machinery Co., Ltd., Seoul Branch Chen updated design theory, increase reliability and service life. United States, Britain, Japan and other countries to promote the use of finite life design theory as an alternative to the traditional infinite life design theory and method, and accumulated fatigue damage theory, fracture mechanics, finite element method, optimization design, computer-controlled electro-hydraulic servo fatigue Test Technology, fatigue strength analysis method and other advanced technologies applied to the study of the hydraulic excavator strength, and promote the efficiency and competitiveness of high quality products. The United States made dynamic design analysis method of dynamic strength evaluation, and the creation of a theory to predict product failure and updates. Japan enacted the strength assessment procedures l hydraulic excavators member, nine positive mixer, developed the reliability of information processing systems. Under the guidance of the basic theory of the above, by means of a large number of tests, shorten the research cycle of new products, accelerated the process of upgrading the hydraulic excavator, and improve their reliability and durability. For example, the operating rate of the hydraulic excavator of 85% to 95%, the service life of over 10,000 hours. Xuzhou Machinery Co., Ltd. Branch Chen Seoul Seoul Branch Chen Qin Hongqiao is located in Xuzhou City Industrial Park, the existing production sites over 20,000 square meters, with all kinds of mechanical processing equipment more than 30 sets of testing equipment, instruments, Instrumentation is complete, and the establishment of a complete and effective quality assurance system, the company has strong qualifications. The company has a high-quality personnel, mixers, with an independent research and development capabilities, the company developed the production of loaders, skid steer loaders and supporting equipment, concrete mixers model, quality, quality, product diversification aids An enclosed-type sweepers, snow machine, hold the fork, push manure, a fork and other widely used in various industries, also Xu workers, building workers, Liugong, Long Engineering, Charlotte, Caterpillar, Doosan, Gail , Case, New Holland and other well-known manufacturers supporting the processing enterprises, and in most cities across the country to establish a dealer.

Preventive measures (1) strictly in accordance with the rules and driving essentials operation, to avoid the shift 'to fight tooth', in order to reduce the wear of gears. (2) the strict implementation of the maintenance system, strengthen the maintenance shifting device. When should shift levers Department improperly connected timely adjustments to ensure good performance shifter. (3) focus on the repair and maintenance of the self-locking mechanism, reduce the role of positioning or mis-aligned performance positioning ball, spring and fork shaft, should be repaired or replaced, the performance of self-locking self-locking mechanism is in good condition . (4) when assembling the transmission, should strictly follow the rules operate to ensure the correct transmission of each mechanical adjustment, tight set appropriately. When larger downhill side, the driver should be strictly in accordance with the downhill action essentials operate, must not illegal. _ _ Nine positive mixer mixer Chen Seoul Branch (quality businessmen) are provided by Xuzhou Machinery Co., Ltd., Seoul Branch Chen.
