卡特 320 D

Cat C6.4 ACERT electronically controlled six-cylinder engine offers a faster power response and more stable fuel consumption compared to the 320C mechanical pump; it meets the national standard II emission standards without a DPF. Ordinary diesel fuel can be used on construction sites, and there is a large supply of spare parts in the market. The hydraulic system pressure has been increased to 35 MPa, resulting in superior digging force and crushing power compared to the 320C. It comes with an oil return regeneration system, faster circulation speed, and higher efficiency for loading earthwork. The 320D L extended chassis is the mainstream in the market. It has a larger ground contact area for the tracks, making it less prone to getting stuck in muddy or soft ground. The weight is thicker, and it offers better stability when lifting heavy objects and during long-term crushing. The thickened box-shaped large arms and the integrated X-shaped frame provide better fatigue resistance and less prone to weld cracks. There is an extremely large second-hand circulation volume, and its value retention rate is top among 20-ton old model machines. The combined fuel consumption is 10-13 liters per hour, suitable for all working conditions such as earthwork, mining, municipal demolition, river dredging, and heavy-load infrastructure construction.
