À propos · Caterpillar 322Aperçu
The Caterpillar 322 is a 22-tonne class hydraulic excavator producing 153 hp and fitted with a 1.07 m3 bucket, positioning it in the upper range of the 20-to-25-tonne crawler excavator segment. Built to Cat's established standards for durability and serviceability, the 322 represents a mainstream workhorse configuration suited to a broad range of earthmoving and civil applications. Its operating weight of 22,760 kg places it firmly in a segment that balances reach, lift capacity, and site mobility.
Applications typiquesLieu d'utilisation de cette machine
The 22-tonne excavator class is well matched to road construction, utility trenching, foundation excavation, and general earthmoving on medium to large civil contracts. Machines of this size are routinely deployed in quarry stripping, land clearing, and pipeline work where a balance between productivity and transport weight is required. The 1.07 m3 bucket capacity supports efficient cycle times in cohesive soils, rock-fragmented material, and bulk dig-and-dump operations.
Inspection du marché de l'occasionCe qu'il faut vérifier avant d'acheter
Before purchasing a used 22-tonne excavator in this class, inspectors should prioritise a full undercarriage assessment, as track components represent a significant portion of refurbishment cost on machines of this weight. Verify the condition of the boom, stick, and bucket pins and bushings for play and wear. Request all available service records and confirm that scheduled hydraulic filter and fluid changes have been completed. Check for hydraulic cylinder seal weeping, particularly on the boom and bucket cylinders. Examine the slew ring for backlash and uneven bearing wear. A functional check of all auxiliary hydraulic circuits is recommended if the machine is equipped with a quick-coupler or thumb. Engine oil analysis records, where available, provide useful insight into internal wear trends without requiring disassembly.

Within the 20-to-25-tonne crawler excavator segment, the Caterpillar 322 is regularly cross-shopped against the Komatsu PC210 and the Hitachi ZX225US. The PC210 sits at a slightly lower operating weight and is known for its fuel-efficiency reputation, while the ZX225US offers a reduced-tail-swing configuration that appeals to confined-site operators. The Cat 322 differentiates itself through the wider Cat dealer and parts network and the engine output of 153 hp, which matches or exceeds both competitors in gross power terms. Within the used-market price band for this model, the principal attributes that move a unit higher or lower are total recorded hours, service history documentation, machine configuration (long-reach versus standard boom, cab specification), the presence of quick-coupler systems or hydraulic thumb attachments, undercarriage wear percentage, and overall cosmetic and structural condition.
