Reasons for damage of roller,China Excavator Track Roller

Because the screed on the paver is too heavy, the center of gravity of the whole machine is backward, so the rear supporting wheel of the paver is subject to the greatest stress during its operation and is easy to be damaged. After damage, the paver will rise and fall one by one while walking, and the screed will rise and fall one by one, resulting in a wavy pavement, which directly affects the flatness of the pavement. Therefore, during the operation of the paver, the distance traveled at one time should not be too long and the speed should not be too fast; The roller will generate high temperature during long and fast driving, and its lubricating oil will leak out due to dilution, resulting in damage to the roller. Once a roller is found to be damaged, it should be replaced in time, otherwise its adjacent roller will also be accelerated due to excessive stress. When replacing the roller, its wear should be taken into account. If the wear degree is small, it can be replaced alone, otherwise it should be replaced completely to avoid accelerating the wear of the new roller. The tension of the tracks on both sides should be moderate and consistent, so as to prevent the paver from jumping teeth and deviation when walking, which will affect the smoothness of the road surface; The drive wheel teeth and track shoes of the track shall be in good condition, otherwise it will cause tooth jumping and walking bumps, which will affect the smoothness of the road.China Excavator Track Roller
