How To Properly Maintain The Crawler Mucking Loader?

(1) Keep the crawler mucking loader guide wheel centered

The misalignment of the crawler mucking loader guide wheel has a serious impact on other parts of the walking mechanism, so adjusting the gap between the crawler mucking loader guide wheel guide plate and the crawler is the main point of extending the life of the crawler mucking loader. When adjusting, use the gasket between the guide plate and the bearing to correct it. If the gap is large, remove the gasket; if the gap is small, increase the gasket. The standard gap is 0.5 to 1.0mm, and the allowable gap is 3.0mm.

(2) Turn the crawler mucking loader crawler pin and pin sleeve at the appropriate time

During the wear of the track pins and pin sleeves, the track pitch is gradually extended, resulting in poor meshing between the drive wheel and the pin sleeve, resulting in damage to the pin sleeve and abnormal wear of the tooth surfaces of the drive wheels, which can cause snakes, flaps, and impacts. Greatly shorten the life of the walking mechanism. When the pitch cannot be restored by adjusting the tension, the track pins and pin sleeves need to be turned over to obtain the correct track pitch. At the scene, there are two kinds of moments that determine the turning of the track pin and the pin sleeve; one method is to check the time when the track pitch is extended by 3mm; the other method is to check the time when the outer diameter of the pin sleeve is worn by 3mm.

(3) crawler mucking loader

When the bolt of the crawler mucking loader is loose, it is easy to be broken or lost, which causes a series of failures. The daily inspection and maintenance should check the following bolts: mounting bolts for track rollers and idlers, mounting bolts for driving gear teeth, track plate mounting bolts, track roller guard plate mounting bolts, diagonal brace head mounting bolts. Refer to the manual of each crawler mucking loader model for the tightening torque of the main bolts.
