Crawler excavators are relatively widely used, characterized by large traction force, low ground contact pressure (generally 0.04-0.15Mpa), good stability, and good off-road performance and climbing performance. It is widely used in occasions with poor working conditions, according to the general rental standard crawler excavator on the ground; if the load capacity of the ground is strong and the ground is uneven, the narrow track type excavator should be leased; if When the load capacity of the ground station in the working condition is poor and the soil is loose, the excavator with extended crawler track and widened crawler pads should be rented; if it is constructed in a swamp, a dedicated crawler excavator for swamp should be rented. Note, however, that the longer the track, the wider the track shoe is, the better. Storage shelves, FAG bearings, Swedish SKF bearings, NSK bearings, Tianjin reducers, linear guide track shoes that are too long and wide will wear faster, and the support wheels, guide wheels and drive wheels will also be subjected to frequent external force impacts too early Damage; Similarly, machines with too short tracks and narrow track shoes that work under unsuitable conditions can also cause premature damage. Excavators with different walking methods have different operation skills.
