Excavator Buckets: Wear-prone Parts and Maintenance | BONOVO

Excavators play a crucial role in engineering operations, with the bucket being a direct contact point with the ground, making its maintenance and care essential. To keep excavators in good working condition, prolong their lifespan, and enhance operational efficiency, regular inspection and maintenance of the bucket and other wear-prone parts are crucial.


Wear-prone Parts of Excavators Include:

Tires/Tracks: Frequent movement of the excavator on the job site due to excavation requirements makes tires/tracks a crucial component. However, they have a relatively short lifespan, prone to wear and tear, and require regular replacement.

Oil Seals: These are sealing components for the hydraulic oil in various excavator tanks and cylinders, vital in preventing fluid leakage and contamination. They endure high wear and tear, often leading to aging and cracking.

Brake Pads: Frequent operations in confined construction sites lead to high usage and subsequent wear and failure of brake pads.

Oil Pipes: Subject to high temperatures and pressures, the oil pipes in an excavator's hydraulic system are prone to aging and cracking, necessitating regular replacement.

Hydraulic Cylinders: Constant exposure to heavy loads during operation makes the hydraulic cylinders susceptible to wear or cracking.

Walking Gear Components: This includes axle sleeves, idlers, rollers, sprockets, and track plates. These components are vulnerable to wear and damage in harsh working conditions.

Bucket Components: Components such as the bucket teeth, lever, floor, sidewalls, and cutting edges experience significant wear due to impact and friction.

Transmission Components: Gears and shafts in reducers are prone to wear and impact due to continuous operation and varying loads.


In addition to the aforementioned parts, there are other wear-prone components in excavators, such as pivot rollers, upper and lower rails, and various pins and shafts. Regular inspection and replacement of these parts are crucial to prolonging the excavator's lifespan. Reasonable operation and maintenance practices are also key to minimizing wear and damage to these components.


I. Maintenance of the Bucket

Cleaning: It is essential to keep the bucket clean. Before any maintenance, thoroughly wash the bucket with clean water and dry it with compressed air to ensure no moisture remains. Stubborn stains can be removed with specialized cleaning agents.

Checking Bucket Teeth Wear: Bucket teeth, the primary working part, wear quickly. Regularly inspect their wear using a straightedge. Replace them promptly when their height falls below the recommended value to maintain digging and scooping efficiency.

Checking Liner Wear: The liners inside the bucket also wear due to friction. Measure their thickness with a straightedge; if it's below the recommended value, replace them to ensure the bucket's structural integrity and lifespan.

Lubrication: Regularly lubricate the bucket to ensure its internal lubrication chamber is filled with lubricant, reducing friction and wear, and enhancing efficiency. Replace the lubricant periodically to maintain lubrication effectiveness.

Inspecting Other Components: Examine the bucket's pins, bolts, and other fasteners for looseness or damage, ensuring all components are securely tightened.


Excavator buckets wear out quickly due to constant contact with abrasive materials. Regular maintenance, including cleaning, lubricating, and replacing worn parts, is key to keeping them in good condition and extending their useful life.


II. Maintenance of Wear-prone Parts

In addition to the bucket, excavators have other wear-prone parts like tires/tracks, oil seals, brake pads, oil pipes, and hydraulic cylinders. To maintain these parts, consider the following measures:

Regular Inspection: Inspect these parts for wear and aging, including cracks, deformations, etc. Record and address issues promptly.

Reasonable Usage: Follow operating procedures to avoid excessive wear and damage.

Timely Replacement: Replace severely worn or damaged parts promptly to avoid affecting the excavator's overall performance.

Cleaning and Maintenance: Regularly clean these parts, removing accumulated dust, oil, and other contaminants to maintain their cleanliness and lubrication.

Using Appropriate Lubricants: Select suitable lubricants for each component and replace them as per recommended intervals to reduce wear and friction.


In conclusion, maintaining the buckets and other wear-prone parts of excavators is crucial for ensuring their long-term stable operation. Regular inspection, cleaning, lubrication, and timely replacement of worn parts can effectively prolong the excavator's lifespan, enhance operational efficiency, and reduce maintenance costs. Additionally, training operators to improve their skills and safety awareness is essential for minimizing component damage and enhancing equipment reliability.
