卡特 336D2L

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 336D2L is the flagship 37-ton long-track heavy-duty hydraulic excavator of Caterpillar’s D2 series from the United States, serving as a benchmark second-hand model widely circulated for open-pit mining and large-scale earthmoving projects worldwide. It boasts three core competitive edges: a self-developed high-torque Cat C9 ACERT six-cylinder engine, high-power energy-saving electronically controlled hydraulic system, and ultra-stable LC long wide undercarriage, which has maintained top recognition among overseas mining clients for years. It is fully compatible with high-intensity heavy-duty operations including rock stripping in open-pit mines, quarry crushing, large roadbed excavation, river dredging, large building foundation construction and heavy loading at sand and gravel yards. Complete hydraulic breaker piping is pre-installed at the factory, so the machine can be directly matched with hydraulic breakers upon delivery to handle both earthmoving and rock breaking tasks. The mechanical direct-injection C9 engine requires no urea aftertreatment, simplifying maintenance greatly. It sustains consistent power output during long-term operations in high-temperature, high-altitude and heavily dusty mine sites, and features outstanding compatibility with low-grade inferior diesel. Caterpillar runs a comprehensive global network of authorized spare parts warehouses with readily available wear parts for engines, hydraulic pumps and undercarriages, minimizing downtime caused by maintenance. The boom and stick adopt thickened wear-resistant steel plates at key stress areas and integrated robotic welding, resisting deformation and cracking under long-term frequent crushing. It stands as the top flagship heavy excavator above 30 tons preferred by overseas mining contractors and large equipment rental companies.
