The bucket assembly is typically made of high-strength abrasion-resistant steel, such as AR400 or Hardox grades. The material grade is often specified as Hardox 450–500 HBW, with tensile strength of 1250–1600 MPa. These materials are chosen to withstand the abrasive conditions of underground mining.
The rated capacity is typically 1.5–4.0 m³, as per ISO 7546. The exact capacity must be matched to the loader class and material density. Always confirm the specific capacity with the manufacturer for your application.
The operating pressure is typically 1.0–1.6 MPa. This pressure is necessary for the hydraulic cylinders to penetrate, curl, lift, and dump the bucket. Verify the exact pressure requirement with the loader's hydraulic system specifications.
Weld quality is critical for high-stress weldments. The standard for full penetration welds on critical joints is ISO 5817-B. When procuring, request documentation or inspection reports confirming compliance with this standard. Always verify with the manufacturer or supplier.
