Used CAT 312D Excavator
✅ Detailed Description
Reliable Power & Efficiency:
The Used CAT 312D Excavator is powered by the Caterpillar C4.2 ACERT engine, delivering 67 kW of output. This engine is optimized for a balance between strong digging force and reduced fuel consumption. With a 2016 manufacture date and only 2760 working hours, this unit offers a significantly longer remaining service life compared to typical used machinery, making it a high-value asset for growing fleets.
Versatile Excavation Capability:
Equipped with a 0.52 m³ bucket and a reinforced MB-type boom, the 312D is engineered for a wide range of tasks, from foundation digging to material loading. It provides a maximum horizontal reach of 8.17 meters and a digging depth of 5.54 meters, ensuring it can handle mid-scale utility and landscaping projects with ease. The advanced hydraulic system ensures smooth, multi-function control, allowing for precise operation in sensitive environments.
Structural Durability & Comfort:
The 312D features a rugged undercarriage with 500 mm track shoes, providing excellent stability and low ground pressure for soft terrain. The operator-friendly cabin is designed with wide visibility and ergonomic controls to maintain productivity throughout long shifts. At ZW Group, we conduct rigorous technical inspections on all used CAT units, ensuring that the engine, hydraulics, and structural components meet international performance standards before export.
