The CAEL 66" Extreme-Duty Skeleton Digging Bucket is engineered for heavy-duty sifting, trenching, material separation, land clearing, and large-scale excavation projects. Designed for 30–40 ton class excavators, this attachment is built to deliver aggressive digging and penetration while allowing unwanted soil and smaller material to pass through during excavation.

Constructed with reinforced T1 structural steel and AR400 wear-resistant components, the CAEL Extreme-Duty Skeleton Bucket is designed for demanding pipeline, construction, and excavation applications where strength, durability, and material separation are essential.

Applications

The CAEL Extreme-Duty Skeleton Digging Bucket is ideal for pipeline excavation, heavy-duty trenching, land clearing, rock separation, root removal, and mixed-ground excavation.

Its open-frame design allows loose soil and smaller material to fall through while retaining larger rocks, roots, and debris. This helps reduce retained load and improve excavation efficiency while maintaining strong breakout performance.

Suitable for:

• Heavy-duty trenching
• Pipeline excavation
• Rocky soil excavation
• Rock and debris separation
• Root removal
• Land clearing
• Mixed-ground excavation
• Large-scale construction projects

Built for Extreme-Duty Conditions

The bucket is constructed with reinforced T1 structural steel and AR400 wear-resistant steel in high-impact and high-wear areas, including the ribs and cutting edges.

Replaceable pin-on teeth make servicing easier while helping maintain aggressive digging performance. The robust rib construction provides increased structural strength and is designed to withstand significant impact, abrasion, and demanding excavation conditions.

Compatible With

• WBM 300 Wedge Coupler
• Caterpillar 336 – 90/100 mm Pins
