Loader shovel teeth wear out quickly? Proper use can extend their life by 50%?

Working angle: Is 30°~45° the golden range?

Many operators are accustomed to inserting the shovel teeth vertically into the material, thinking that this will "go deep into the soil and load quickly", but in fact, this operation will cause the shovel teeth to bear too much impact. A case of a mining construction team shows that when the angle between the shovel teeth and the ground is maintained at 30°~45°, the insertion resistance can be reduced by 30% and the wear rate can be reduced by 40%. This is because the tilt angle allows the shovel teeth to be evenly stressed and avoids concentrated loads on a single tooth. It is recommended that when loading hard materials (such as iron ore and granite), the angle can be slightly larger (40°~45°) to reduce instantaneous impact; when loading loose materials (such as sand and coal), the angle can be slightly smaller (30°~35°) to improve loading efficiency.

Material screening: Should different shovel teeth be selected for different materials?

"Using one shovel tooth to the end" is a misunderstanding of many construction teams. In fact, the tooth shape and hardness of the shovel teeth need to match the material characteristics. For example, for steel bars and concrete blocks in construction waste, wear-resistant shovel teeth with reinforcement should be selected, with a hardness of HRC55 or above, which can resist cutting by sharp objects; and for agricultural bulk loading, arc-shaped shallow-tooth shovel teeth are more suitable, which can reduce material adhesion and reduce energy consumption.

Daily maintenance: Can a few simple steps save thousands of yuan?

Many people ignore the daily inspection of shovel teeth and replace them until they break. In fact, small problems will accelerate wear if not handled in time. It is recommended to spend 3 minutes to check before each operation: ① Whether the connecting bolts between the shovel teeth and the bucket are loose. If there is an abnormal sound, tighten them immediately; ② Whether the shovel tooth edge is curled, and slight curling can be repaired by grinding with an angle grinder; ③ Whether there is a crack at the root of the shovel tooth. If a crack is found, it needs to be replaced in time to avoid safety accidents caused by breakage.

These seemingly subtle operating skills and maintenance details are actually the key to extending the life of the shovel teeth and improving construction efficiency. From adjusting a perfect working angle, to matching the shovel teeth for different materials, to the 3-minute detailed inspection before each operation, each step is a vivid interpretation of "30% equipment, 70% maintenance".

You know, reducing unnecessary wear means one less downtime for replacement; avoiding a break caused by improper maintenance saves additional maintenance costs and safety risks. For operators, incorporating these skills into daily life can not only make the shovel teeth more "durable", but also experience the efficiency and peace of mind of the tacit cooperation between people and equipment in day-to-day operations. After all, if the shovel teeth can "hold" for one more day, the construction progress will be more guaranteed, and the income in your pocket will be more substantial.
