FAQ
Q1: What soil classifications is this bucket suitable for?
A1: It effectively handles CL, CH, SC soil types per USCS classification, and moderately weathered rock (UCS up to 40 MPa).
Q2: Can it be used with non-Kelly drive rigs?
A2: While optimized for Kelly systems, adapter kits for certain rotary drive heads are available upon request.
Q3: What is the lead time for custom diameters?
A3: Standard sizes ship in 7 days; custom diameters require 15-25 days based on complexity.
Q4: How are wear parts replaced in the field?
A4: Cutting teeth use bolt-on replacement; wear plates feature welded-on design with field-weldable options.
Q5: Is the bucket suitable for continuous flight auger (CFA) rigs?
A5: No, this model is specifically engineered for Kelly bar driven rotary drilling applications.
Q6: Do you provide tooth sharpening services?
A6: We offer recommended carbide tip refurbishment partners but don't perform direct sharpening services.
Q7: What documentation accompanies the product?
A7: Each bucket ships with material certification, dimensional drawings, and load test reports.
Q8: Can it handle boulder layers?
A8: While effective in gravel/cobble layers, dedicated rock buckets are recommended for frequent boulder penetration.
