The Role of Cutting Edges on Loader Buckets

The cutting edges on loader buckets serve as the core cutting components, fulfilling key functions in the following aspects:

I. Core Function

Primary Cutting Edge

As the foremost cutting component of the bucket, the cutting edge directly penetrates material to generate initial cutting force, handling over 90% of material fragmentation tasks. In rock applications, V-shaped serrated cutting edges enhance cutting efficiency by 40%.

Load Transmission

Through the welded surface, they transmit digging resistance to the bucket's main structure. Medium-manganese alloy steel (hardness HB500+) withstands high-intensity impacts.

II. Structural Characteristics

Position Design: Located at the foremost lower end of the bucket, often featuring reserved holes for installing bucket teeth and secondary cutting edges.

Material Requirements: Utilizes wear-resistant medium-manganese alloy steel. Forging + heat treatment process enhances wear resistance by 60% compared to cast types.

III. Performance Impact

Parameter    Premium Cutting Edge Effect    Substandard Cutting Edge Risk

Operational Efficiency    Reduces digging cycle by 25%    Increases fuel consumption

Bucket Lifespan    Extends overall lifespan by 30%    Causes side plate cracking

IV. Maintenance Essentials

Inspect cutting edge thickness every 500 hours; replace if wear exceeds 5mm.

Weld surface flatness tolerance must be <3mm/entire plate to prevent stress concentration.

(Note: Select cutting edge type based on operating conditions; e.g., rock applications recommend V-shaped teeth + high-manganese steel combination.)
