We’re happy to help you find the best option for your application.
The 315506305 bucket body is developed for the XCMG XE690DK large excavator, weighing 4420kg. It is fabricated with thick-specification wear-resistant base material and full penetration welding, with additional reinforcement at the bucket bottom, side edges, and tooth holders, suitable for extreme conditions such as mining overburden removal, heavy earthworks, and large-scale foundation construction.
The product’s connection parameters align with the XE690DK working attachment. Pin hole center distance and opening width follow OEM specifications, requiring no on-site modification during installation. The load-bearing frame is cut from thick single plates to reduce the number of splice welds and lower stress concentration risks.The front cutting edge and tooth holders are made from high-hardness wear-resistant alloy plates, capable of withstanding long-term operation in hard rock and high-abrasion formations. The internal curvature is optimized along the large bucket digging trajectory, achieving a higher fill factor and relatively lower fuel consumption per cycle.

Features & Advantages
Thick Single-Plate Frame: Main structure cut from thick steel plates to reduce splice welds and lower structural weak points.
High-Hardness Cutting Configuration: Edge plate and tooth holders made from high-hardness alloy to resist long-term erosion from hard rock and high-abrasion materials.
OEM-Level Hole Tolerance: Pin holes and opening width machined strictly to XE690DK specifications for installation accuracy.
Large Bucket Curvature Optimization: Digging path matched to material flow for higher per-cycle loading and work efficiency.
Full Penetration Critical Welds: Main stress joints use complete penetration to eliminate surface pseudo-welds and internal defects.
Unit-by-Unit Dimensional Check: Hole positions and profile verified individually to avoid batch deviations.
Heavy-Duty Adaptability: Reasonable reinforcement distribution for continuous high-intensity operations such as mining overburden removal.
