Performance self-locking mechanism to prevent the transmission of decline 'jump stop', sales of second-hand excavator recovered the excavator in the transmission of Ⅱ, Ⅲ gear and Ⅳ, Ⅴ shift fork shaft side cover hole and Ⅰ, reverse gear Jun'an has played the role of self-locking ball and spring in the fork. When starting positioning self-locking effect of the elastic spring weakened or broken, the self-locking performance self-locking mechanism will decline until it disappears, used excavators recycling factory, resulting in transmission 'jump stop'. Meanwhile, the recovery of used excavator recess businesses, locate the ball, or if the fork shaft wear and tear, Hefei used excavators recovery, also can cause transmission 'skip-shift'. Hydraulic Excavator General by the working device, the upper body and lower body composed of three parts. According to its structure and purpose can be divided into: Crawler, tire type, walker, hydraulic, semi-hydraulic, full swing, non-full rotation, general-purpose, special type, articulated, telescopic boom and other types. Working device is a direct means to complete the mining task. It consists of the boom, arm and bucket three parts hinged together. In order to meet the various needs of different construction operations, the hydraulic excavator can be equipped with a variety of work equipment, such as digging, lifting, loading, smooth, clamps, dozer, hammer, auger drilling and other work tools. Guizhou used excavators recovered, Kim Ho used excavators, used excavators recovered transactions provided by the Shanghai Used Construction Machinery Co., Ltd. Jin Hao. Guizhou used excavators recovered, Kim Ho used excavators, used excavators recovered transaction is Shanghai Jin Hao Used Construction Machinery Co.
