BENEFITS AND FEATURES

Hydraulic System Hydraulic system pressure from the two hydraulic pump system delivers terrific digging performance and productivity.

Pilot System An independent pilot pump enables smooth, precise control for the front linkage, swing, and travel operations.

Hydraulic Cylinder Snubbers Snubbers are located at the rod-end of the boom cylinders and both ends of the stick cylinders to cushion shocks while reducing sound levels and extending component life.

Hydraulic Activation Control Lever With the hydraulic activation lever in the neutral position, all front linkage, swing, and travel functions are isolated.

Component Layout The hydraulic system and component locations have been designed to provide a high level of system efficiency. The main pumps, control valves, and hydraulic tank are located close together to allow for shorter tubes and lines between components, reducing friction loss and pressure drops.

Hydraulic Cross-Sensing System The hydraulic cross-sensing system utilizes each of two hydraulic pumps to 100 percent of engine power under all operating conditions. This improves productivity with faster implement speeds and quicker, stronger pivot turns.

Auxiliary Hydraulic Valve Control circuits are available as attachments to improve versatility. They allow operation of pressure tools.

Heavy duty structural components and high wide undercarriage are the backbone of the machine’s durability.

BENEFITS AND FEATURES

Robotic Welding Up to 95% of the structural welds on a Cat Excavator are completed by robots. Robotic welds achieve over three times the penetration of manual welds.

Long, Heavy-Duty, High-Wide (HDHW) Undercarriage The HDHW undercarriage maximizes stability and lift capacity over the front and side, compared to a standard long undercarriage. The higher ground clearance is ideal in rocky environments, bringing the carbody and upperframe in safer high position. The durable X-shaped box-section carbody absorbs stresses, and provides excellent resistance to torsional bending. Robot-welded track roller frames are press-formed, pentagonal units to deliver exceptional strength and service life.

Rollers and Idlers Sealed and lubricated track rollers, carrier rollers, and idlers provide excellent service life, to keep the machine in the field longer.

Tracks The 340D2 L track links are assembled and sealed with grease to decrease internal bushing wear, reduce travel noise and extend service life lowering operating costs.

Counterweights The 6.25 mt and 8.45 mt counterweights are bolted directly to the main frame for extra rigidity. The 8.45 mt HD counterweight makes a better choice for heavy lifting applications that require additional machine stability, especially with Mass Excavation front parts.
