The monitor and service life from these important is a full-color graphical display that components. pg. 7 allows the operator to understand the machine information easily. Overall, the new cab provides a comfortable environment for the operator. pg.
Reduced Radius The Caterpillar 320D LRR is designed for high maneuverability in confined spaces. Comfort. The cab of the 320D LRR is the same full-sized cab with all the amenities and attachments found on the cab of the 320D L. Reduced Radius. The tail swing of this machine has been reduced where the back end of the machine won’t extend beyond the length of the tracks. The tail swing is just 2.0 m (6'7") as compared to the 2.75 m (9'0") on the 320D.
C6.4 with ACERT™ Technology The Cat® C6.4 gives the 320D LRR exceptional power and fuel efficiency, unmatched in the industry, for consistently high performance in all applications. Cat C6.4. The Cat C6.4 with ACERT™ Technology introduces a series of evolutionary, incremental improvements that provide breakthrough engine technology. The building blocks of ACERT Technology are fuel delivery, air management and electronic control. ACERT Technology optimizes engine performance while meeting U.S.
Hydraulics Cat® hydraulics deliver power and precise control to keep material moving. Heavy Lift. The 320D LRR features the addition of a heavy lift, which increases system pressure to 36 000 kPa (5,220 psi), giving even more lift capacity over the front. Heavy Lift is activated by depressing the soft switch on the right hand console. As the pressure increases, the engine speed is reduced, which allows better control while lifting objects. Pilot System.
Structures 320D LRR is designed to handle the most rugged operating conditions, while providing long life and value. Robust Undercarriage. A solid foundation built tough to absorb the stresses of everyday work. • Rollers and idlers are sealed and lubricated to extend service life. • Track links are assembled and sealed with grease to decrease internal bushing wear and increase life by as much as 25%, when compared to dry seal undercarriages.
Operator Comfort Caterpillar offers the most intuitive and easy to operate excavators while providing great all around visibility and exceptional operator comfort.
Operator Station. The layout of the interior has been redesigned to maximize operator comfort and reduce operator fatigue. • Frequently used switches have been relocated for easier access. • Consoles and armrests have been redesigned for better comfort and adjustability. • More seat options – choose from the standard mechanical suspension seat, or the optional air suspension seat with heater. Both provide excellent comfort. Standard Cab Equipment.
Booms, Sticks and Bucket Linkages Built for Performance and long service life, Caterpillar® booms and sticks are large, welded, box-section structures with thick, multi-plate fabrications in high stress areas. Bucket Linkage. The power link improves durability, increases machine-lifting capability in key positions and is easier to use than compared to the previous power link. Lifting from the power link lift eye gives you the optimum lift performance.
Work Tools – Attachments The 320D LRR has an extensive selection of work tools to optimize machine performance. Wide Variety of Work Tools.
Versatility A wide variety of optional factory-installed attachments are available to enhance performance and improve job site management. Product Link.
