卡特 330 B

Cat 3306TA is a six-cylinder large-displacement mechanical direct injection intercooled engine with a 10.5L capacity. It has extremely strong low-speed torque. It is a pure mechanical pump without after-treatment and is suitable for low-quality diesel at construction sites. It has a large inventory of spare parts and low maintenance costs. The high-flow 245L/min hydraulic system has strong digging force and crushing power. It is equipped with a dual-path crushing hammer oil circuit and is compatible with large crushing hammers, heavy-duty grabbers, and spiral drills. The 330BL extended chassis is the mainstream in the market. The ground contact area of the tracks is larger, making it less likely to get stuck in muddy or soft mining land. The counterweight is heavy, ensuring stable operation during hoisting and heavy-duty crushing. The heavy-duty box-shaped large arm and an overall strengthened X-shaped frame are used. It is resistant to fatigue in heavy mining conditions and the weld seams are less likely to crack. There is a large second-hand circulation volume and a high preservation rate. The combined fuel consumption is 14–18L/h, suitable for large earthwork, mining, infrastructure heavy-duty, river dredging, and large-scale demolition projects.
