During construction, a rotary drilling rig should adjust the track tension according to the soil quality to cope with the differences in soil types at various construction sites. Doing so can also extend the lifespan of the machine. In soft soil, tracks and track chain links easily accumulate mud, so the tracks should be slightly looser to prevent abnormal stress on the track chain links due to mud adherence. At construction sites with pebbles, the tracks should also be adjusted to be slightly looser to prevent bending of the track pads when moving over pebbles. On firm and flat ground, it's better to adjust the tracks a bit tighter. Adjustment of track tension: If the tracks are too tight, there will be a decrease in walking speed and power. This not only leads to reduced operational efficiency but also causes abnormal wear due to excessive friction on the pins and bushings. Conversely, if the tracks are too loose, they hang slackly over the drive sprocket and idler sprockets, causing greater wear or damage. Moreover, when the slack tracks sag excessively, they may contact and damage the frame. Even with a reinforced undercarriage, incorrect adjustment can lead to unexpected failures.

When operating a rotary drilling rig, attention should also be paid to reducing wear. Idler wheels, carrier rollers, drive sprockets, and track chain links are parts that are prone to wear, but the extent of wear can vary greatly depending on whether regular checks are carried out. Therefore, a little time spent on proper maintenance can effectively control wear. Continued use in a state where some idler wheels and carrier rollers are not rotating may lead to uneven wear of the rollers and also cause wear of the track chain links. If a non-rotating roller is found, it must be repaired immediately to avoid other faults. Repeatedly walking on sloped surfaces and making sudden turns over time can cause the side of the track chain links to contact the sides of the drive sprockets and guide wheels, thereby increasing wear. Therefore, walking on slopes and making sudden turns should be avoided as much as possible. Straight-line movement and wide turns can effectively prevent wear.

Bolts and nuts should be carefully checked: Long-term operation of the machine can cause bolts and nuts to loosen due to vibrations. This is especially true for bolts and nuts on the undercarriage, which are easily affected. If the machine continues to operate with loose track plate bolts, gaps will form between the bolts and the track plates, leading to cracks in the track plates. Furthermore, the formation of gaps may enlarge the bolt holes between the tracks and the track chain links, leading to the severe consequence of being unable to tighten and necessitating the replacement of both tracks and track chain links. Therefore, bolts and nuts should be regularly checked and tightened to reduce unnecessary costs.
