Excavators - Xuzhou Machinery Co., Ltd., Seoul Branch Chen 'jump stop' Cause (4) External sudden load changes due to the nature of the excavator and machine design their own reason, sudden changes in the external load will cause its transmission ' hop gear '. When the road surface uneven, machines for downhill driving or improper driving route leaving the outside load changes suddenly, this sudden change in load through the wheel, the drive shaft of the transmission gear in the ring gear, so gear gear due to the axial thrust and disengaged, causing the transmission 'jump stop'. (5) improper operation excavator on a slope with (especially downhill driving), if the improper operation will lead to the transmission 'skip-shift'. Xuzhou Branch Chen Seoul Machinery Co., Ltd. - ditching machine ditching machine is an efficient and practical means new chain opener. The main from the power system, deceleration system, the chain of transmission and sub-soil system. Diesel belt after passing through the rotation to the clutch, drive walk gearbox, drive shaft, rear axle to achieve linear motion chain-type trenching machine forward or backward.
