Excavator  Undercarriage PartsSK200 Carrier Roller Upper Roller

  Drag sprocket function: the carrier roller is used to reduce the track sag between the idler and the drive sprocket, and support the track loose edge from the drive sprocket, and when the track in the engagement is tightened, it is used to guide the track to disengage from the mesh, when installing a drag sprocket, it should not be placed in the middle of the wheel base, but closer to the drive sprocket. It is worth noting that if the diameter of the e-mail sprocket is too small, there is a possibility that the track will slip along the e-tramp rim, which will grind out a "light plane" according to the wear of the e-mail rim, which will cause the e-chainer to stop rotating.

  Drag sprocket installation arrangement: when the drag sprocket is installed on the excavator, a single arm support is adopted, and the support block is heightened, so that the space below is increased, and the obstruction of silt and stones is avoided when walking, and the wear between the track section and the reducer bearing is also avoided, and the passability of walking is improved.
