Heavy-duty, powerful and fuel-saving – the new CAT® 326 D2

The new Cat® 326 D2 hydraulic excavator combines high productivity, versatility and low operating costs with exceptional reliability. With a maximum operating weight of 26.345 t, the 326 D2 uses the Cat C 7.1 engine, which is rated at 140 kW (ISO 9249). It meets exhaust emissions equivalent to U.S. EPA Tier 2, EU Stage II, and China Tier 2 emission regulations and is equipped with a three-stage fuel-filtration system for optimum protection of fuel-delivery components. Premium features include cross-sensing hydraulics for greater efficiency, robust major structures for long-term durability, ergonomic cab for increased productivity, and simplified routine maintenance for reduced operating costs.

The 326 D2 pilot-operated hydraulic system provides 35 MPa main ­pressure and flow rates as great as 494 L/min for optimum hydraulic power in difficult applications. Dual main pumps continuously utilize 100 % of engine power. Regeneration valves in the boom-down and stick-in circuits speed cycles reduce hydraulic flow requirements and conserve fuel, while cylinder snubbers cushion shock in these circuits. Auxiliary hydraulic valve sections allow adding high- and medium-pressure circuits for work tools.

Depending on the region, the excavator is available with a standard undercarriage, designated the 326 D2, or a long undercarriage, designated the 326 D2 L. The massive, X-shaped, box-section carbody provides resistance to stress as it transfers working forces from the rugged upper mainframe to the high-strength track-roller frames. Structural welds are 95 % robotic, achieving three times the penetration of manual welds.

Also depending on the region, both the standard 5.9-meter reach boom and heavy-duty 5.9-meter reach boom have two stick options (2.95 m, 2.5 m) to tailor the front linkage to the task, and a mass-excavation 5.3-meter boom with its mass 2.5-meter stick deliver superior digging forces and permit the use of a larger bucket. In addition, a Super Long Reach front linkage features a 10.2-meter boom and 7.85-meter stick. Thus, the maximum digging depth is 6.4–14.590 m and maximum reach at ground level ranges from 9.74–18.3 m.

An ergonomically designed cab features low-effort joysticks, large glass areas to enhance all-around visibility, automatic bi-level air conditioner with defroster. The full-color LCD monitor is 40 % larger compared with the previous monitor and has enhanced resolution and serves as the display for an available rearview camera system. For operator convenience, joystick consoles are adjustable and viscous-rubber mounts between the cab and frame minimize sound and vibration.

To enhance serviceability, filter- and fluid-change intervals are displayed on the main menu of the monitor, and most routine service points are located at ground level. An easy-access, remote-greasing block on the boom delivers lubrication to difficult-to-reach components. SOS (Scheduled Oil Sampling) ports allow technicians to collect reliable samples of hydraulic oil, engine oil and coolant for analysis, and the ­Caterpillar Electronic Technician service tool is conveniently connected behind the cab.

Product availability may vary according to regions of the world.
