Caterpillar heavy duty excavator bucket for Caterpillar Tracked excavator

All Cat/Caterpillar digging buckets/heavy duty rock buckets/dredge buckets are built to withstand harsh working conditions, greatly reducing maintenance costs and extending service life.Whether you choose our OEM-spec line or our performance aftermarket series, every bucket carries a 12-month structural warranty against manufacturing defects in material and workmanship. We provide full traceability—from steel mill certificates (EN 10204 3.1) to welding procedure specifications (WPS). Using genuine OEM-designed buckets from our factory also helps you avoid potential warranty disputes with your machine’s original manufacturer, as we strictly follow SAE and ISO dimensional standards for all pin-to-pin distances and mounting interfaces.

From raw material cutting, precision welding to heat treatment and surface spraying,strict quality control is implemented for every production process. Double anti-rust paint coating protects buckets from rust during long-distance sea transportation.

In rock quarries and demolition sites, buckets face constant shock loading from falling boulders and hydraulic hammering. Our buckets are fabricated with double-walled construction at stress points (heel and side plate junctions) and reinforced with ribbed gussets. All critical welds are performed by certified welders and undergo non-destructive testing (NDT) to guarantee zero porosity or cracking. We also offer a full-wrap heel guard that deflects impact energy away from the bucket’s back plate—a common failure point in competitor products.
