The walking part of the excavator is composed of supporting sprockets, track rollers, Carrier roller Idler and track links, etc. After running for a certain period of time, these parts will wear to a certain extent. However, if you want to maintain it on a daily basis, as long as you spend a little time for proper maintenance, you can avoid the “major operation of the excavator leg” in the future. Save you considerable repair money and avoid delays caused by repairs.
The first point: If you repeatedly walk on the inclined ground for a long time and turn suddenly, the side of the rail link will come into contact with the side of the driving wheel and the guide wheel, thereby increasing the degree of wear. Therefore, walking on sloped terrain and sudden turns should be avoided as much as possible. Straight line travel and big turns, can effectively prevent wear.
The second point: if some carrier rollers and support rollers cannot be used for continuous use, it may cause the rollers to be misaligned, and may also cause the wear of the rail links. If an inoperable roller is found, it must be repaired immediately! In this way, other failures can be avoided.
The third point: the rollers, the mounting bolts of the chain rollers, the track shoe bolts, the driving wheel mounting bolts, the walking piping bolts, etc., because the machine is easy to loosen due to vibration after a long time of work. For example, if the machine continues to run with the track shoe bolts loose, it may even cause a gap between the track shoe and the bolt, which can lead to cracks in the track shoe. Moreover, the generation of clearance may also enlarge the bolt holes between the crawler belt and the rail link, resulting in the serious consequence that the crawler belt and the rail chain link cannot be tightened and must be replaced. Therefore, bolts and nuts should be inspected and tightened regularly to reduce unnecessary maintenance costs.
