CAT 320

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 320 is Caterpillar’s new-generation 22-tonne medium main hydraulic excavator, designed for full-range construction applications including earthmoving, municipal trenching, site grading, infrastructure loading and light mine stripping. Equipped with Caterpillar’s original intelligent electronically controlled hydraulic system and low-emission C4.4 engine, this machine comes factory-standard with smart features such as the 2D grade control system, payload weighing and automatic digging assist — functions that competitors in the same weight class only offer as costly optional extras. Three variants are available: standard 320, cost-effective 320GC and compact lightweight 320GX, catering to heavy-load operations, low operating cost and confined-site construction respectively. It boasts a massive global installed base with highly interchangeable spare parts and class-leading residual value, making it the most popular 20-tonne excavator for contractors and export trading worldwide.
