Because there are so many different types of excavator buckets, it’s a good idea to consider renting one when you need it for a specific task. If you have a wide range of operations and change bucket types frequently, purchasing a used or rented bucket, careful maintenance inspections are essential to ensure its performance and safety.
1. Inspection Points
1. Welded Areas: Examine the bucket’s welded area to recognize the presence of cracks, dents or deformations, and especially the rust rings surrounding the welds, which are indicators of potential structural weaknesses.
2. Rust Assessment: Rust is a direct response to overuse or improper protection of the bucket. Evaluate the level of corrosion to determine if it is worth refurbishing or is nearing the end of its useful life.
3. Bucket Teeth Wear Condition: Bucket teeth, as critical working parts, are made of low alloy steel to withstand high intensity operations. Wear forms a sector that is still usable, but with a significant drop in efficiency. It is necessary to consider timely replacement of the tooth section or planning for overall replacement.
4. Accessibility of spare parts: The long-term use of the bucket depends on the continuous supply of wearing parts such as bucket teeth. For discontinued models, it is necessary to confirm in advance the reliability of the source of spare parts, price reasonableness and ease of procurement.
5. Matchability: Whether the bucket is leased, new or used, you need to make sure that it is a perfect match for the excavator model. Excessively heavy buckets will affect operational efficiency and even cause damage to the excavator body, therefore, before installation, you need to strictly check the compatibility of bucket size and weight with the excavator specications.
6. Functional Test: After the installation is completed, perform the opening and closing action test, check the fastening status of the bushings, pins and couplings, etc. to ensure that there is no looseness.
7. Digging Test: Examine the performance of the bucket through actual digging operation, record and compare its operating cycle time, as a basis for evaluating the efficiency of the bucket and comparing it with other buckets.
2. Selecting Excavator Bucket Size
In most construction projects, the use of a bucket significantly contributes to increased productivity by reducing the number of tooling operations required during the cycle time. Maximizing efficiency should be the primary consideration when selecting an excavator bucket size, unless there are specific size constraints on the project, such as precise trench excavation scenarios.
Decisions about bucket capacity need to be high specialized, and it is vital to ensure that it matches the excavator model. For example, it would be inappropriate to equip a 10-tonne excavator with a bucket designed for a 20-tonne class, as an oversize bucket would increase the load on the excavator, lengthening the operating cycle and in turn reducing overall efficiency and potentially jeopardizing the stability of the excavator. Therefore, the professional advice is to choose the bucket size that best suits the excavator’s specifications and operational needs without sacrificing the specific operational needs, in order to maintain and improve construction efficiency.
