1. Premium Used CAT 312D: Fully Inspected, Proven Platform The CAT 312D is one of 's most successful 12-ton models, prized for its robust build quality and straightforward maintenance. This premium used unit has passed a comprehensive multi-point inspection including engine compression test, hydraulic pressure verification, and undercarriage wear measurement with full video documentation provided.
2. Cat C4.2 Engine: 70kW for Demanding Mid-Size Work The 4.2-liter Cat C4.2 diesel delivers 70kW at 2,200rpm — ample power for foundation excavation, utility trenching up to 4 meters deep, and loading dump trucks on mid-size construction sites. Its mechanical fuel injection system is field-serviceable, reducing dependence on specialized diagnostic equipment in remote locations.
3. 12-Ton Stability: Solid Platform for Attachment Versatility With a 12,300kg operating mass and wide-gauge undercarriage, the 312D provides a stable base for heavy attachment work including hydraulic hammer operation, rock breaking, and scrap handling. The 0.52m³ bucket balances cycle speed with material volume for efficient trenching and bulk excavation.
4. Global Parts Availability: Never Wait for Critical Components As a high-volume Cat model, the 312D benefits from extensive parts inventory at Cat dealers worldwide. Filters, hoses, track components, and engine parts are typically available off-the-shelf. CE and EPA certified with 24/7 multilingual technical support and 48-hour warranty parts dispatch.
