1. What is the Heavy Duty Rock Bucket and what is it used for?

The Heavy Duty Rock Bucket is an excavator attachment designed for digging and loading in high-abrasion environments such as rock, quarrying, mining and heavy construction. It is a reinforced bucket engineered for high-intensity work and long service life.

2. What materials are used to manufacture this rock bucket?

Standard construction uses Q345B plus NM400 wear steel. Hardox 400/500 is also available. The design includes strengthened bottom plates, side protective plates, wear strips and wear blocks for improved abrasion resistance.

3. Which excavators is this bucket compatible with?

The bucket is intended for crawler excavators and is available for machines in ranges such as 20 ton, 35 ton and 45 ton. Compatibility depends on the excavator arm pin size, center distance and linkage — provide your excavator model and pin dimensions when ordering for a precise fit.

4. What are the main dimensions and capacities?

Typical bucket capacities range from 2.4 to 3.4 m3 (3.1–4.4 yd3). Width is listed at 1676 mm. Attachment weight is typically around 1500 kg, though final weight depends on size and material choices.

5. Are teeth and adapters included with the bucket?

Buckets can be supplied with original or domestic adapters and teeth. Confirm your preference (OEM-style or local alternative) when placing the order.

6. What certifications and quality assurances does the product have?

The product line has been certified to SAE, SGS and ISO9001 standards and has passed national authoritative monitoring and machinery tests. Video outgoing inspection and test reports can be provided.

7. What warranty and after-sales support are offered?

The bucket carries a 1-year quality guarantee. Core components (as specified) have a 6-month warranty. After-sales support is provided online; wear items such as teeth and cutting edges are typically excluded from standard warranty coverage.

8. What is the lead time and how is the bucket packaged?

Standard lead time is 10–15 days. Units are packed on wooden pallets or in wooden cases for export shipping.

Yes. OEM/ODM support is available. You can customize dimensions, material (e.g., Hardox options), color and mounting interface — provide specifications or drawings when requesting a quote.

11. Does the bucket include hydraulic components like cylinders or pumps?

No. The attachment is a mechanical bucket. Hydraulic components listed as OEM are for reference to excavator systems; hydraulic pumps, valves and cylinders remain part of the excavator and are not supplied with the bucket.

12. What maintenance is recommended to extend bucket life?

Regularly inspect and replace wear parts (teeth, adapters, cutting edges, wear strips/blocks). Keep mounting pins and bushings greased, check for cracks and weld integrity, and avoid using the bucket as a pry bar. Timely replacement of worn components greatly extends service life.

13. What applications is this heavy-duty rock bucket best suited for?

It is suited for rock digging, quarry loading, mining operations, heavy civil construction and other high-abrasion environments where reinforced wear protection and high bearing capacity are required.

To place an order, provide your excavator make/model, operating weight, pin diameter and center distance, desired bucket capacity or dimensions, material preference and any special requirements. A sales representative will confirm compatibility, lead time and price.

15. What spare parts and replacement wear items are available?

Common spare parts include teeth, adapters, cutting edges, wear strips, bushings and pins. Specify the bucket model and serial or key dimensions so we can supply correct replacement parts.
