卡特 320D2L

Standard and Optional Buckets Standard Bucket: Typically equipped with a standard backhoe bucket with a capacity of approximately 1.4 - 1.6 m³, suitable for general earthmoving and excavation. Optional Range: Depending on working conditions, buckets of various capacities can be fitted, ranging from 0.64 m³ to 1.75 m³, to handle everything from light materials to heavy-load mining operations. Hydraulic Breaker One of the most common attachments. Used for breaking hard rock, concrete pavements, or for secondary crushing in mining operations. Hydraulic Scrap Grapple / Grab Used in scrap steel processing, timber handling, or waste sorting. Replaces the bucket to achieve grabbing and loading functions. Rock Cutter / Trencher Used to cut narrow, straight trenches in hard rock. Commonly used for slope trimming or pipeline installation.

The Cat 320D2L is a 20-ton medium crawler excavator with an extended undercarriage, where the suffix "L" stands for longer and wider track frame. It is powered by a mechanical direct-injection Cat C7.1 engine that tolerates low-quality diesel fuel, making it highly suitable for remote construction sites and regions with poor fuel standards. Its newly optimized load-sensing hydraulic system balances powerful digging performance and fuel efficiency, cutting fuel consumption by approximately 8% compared to previous generations. The extended undercarriage significantly boosts machine stability, preventing tail lifting during heavy loading operations on muddy ground and quarries.
