Compact Radius Compact radius design delivers top performance in tight quarters.
Compact Radius Design. The 321C LCR features a compact radius, making it ideal for working in tight areas such as: next to buildings, highway construction – limiting lane closures, logging roads and other tight areas where space is restricted. Operator Confidence. Due to the 321C LCR’s compact working envelope, operators can work in confidence that the counterweight will not swing into any object behind them, which allows the operator to concentrate on the task at hand. Working Envelope. The 321C LCR has been designed to rotate with little to none of the counterweight extending beyond its tracks, and working within its width. To further minimize the working envelope, the 321C LCR’s boom is positioned further back in the upper frame as compared to a standard excavator. This reduces the front swing radius when the boom is pulled all the way up and the stick is brought back.

Engine and Hydraulics The Cat 3066 ATAAC engine and hydraulics give the 321C LCR exceptional power, efficiency, and controllability unmatched in the industry for consistently high performance in all applications
Engine. Six cylinder turbocharged engine built for power, reliability, economy and low emissions will keep the machine up and running. The Cat 3066 ATAAC engine meets Stage II worldwide emissions requirements. Automatic Engine Control. Automatic Engine Control (AEC) with convenient one-touch command. Threestage control maximizes fuel efficiency and reduces sound levels. First stage AEC: Selected when the AEC indicator on the Multipro panel is “OFF”. If a no-load or light-load condition continues for more than 3 seconds, the AEC reduces engine speed by 100 rpm. Second stage AEC: Selected when the AEC indicator on the Multipro panel is “ON”. If a no-load or lightload condition continues for more than 3 seconds, the AEC reduces engine speed to 1300 rpm. Third stage AEC: Pressing the switch on the top of the right hand control joystick when the levers are in neutral position, reduces the engine speed to 1020 rpm. If the switch is pressed again or if a control lever is moved, the engine speed returns to its normal level. Low Sound, Low Vibration. The Cat 3066 ATAAC design improves operator comfort by reducing sound and vibration.
Electronic Control Module. The Electronic Control Module (ECM) works as the “brain” of the engine’s control system, responding quickly to operating variables to maximize engine efficiency. Fully integrated with sensors in the engine’s fuel, air, coolant, and exhaust systems, the ECM stores and relays information on conditions such as rpm, fuel consumption, and diagnostic information. Hydraulic Cross Sensing System. Improves productivity with faster implement speeds and quicker, stronger pivot turns.
Hydraulic Cylinder Snubbers. The hydraulic cylinder snubbers at rodend of boom cylinders and both ends of stick cylinder cushion shocks, reduce sound, and increase cylinder life, keeping the machine working longer. Controllability. The hydraulic system offers precise control to the 321C LCR, reducing operator fatigue, improving operator effectiveness and efficiency, which ultimately translates into enhanced performance.
Fine Swing Control. Fine swing control cushions swing start and stop for better implement control.

Structures 321C LCR structural components and undercarriage are the backbone of the machine’s durability Robotic Welding. Up to 95% of the structural welds on a Caterpillar hydraulic excavator are completed by robots. Robotic welds achieve up to three times the penetration of manual welds. Carbody Design and Track Roller Frames. X-shaped, box-section carbody provides excellent resistance to torsional bending. Robot-welded track roller frames are press-formed, pentagonal units that deliver exceptional strength and service life. Main Frame. Rugged main frame is designed for maximum durability and efficient use of materials. Undercarriage. Durable Cat undercarriage absorbs stresses and provides excellent stability. Rollers and Idlers. Sealed and lubricated track rollers, carrier rollers, and idlers provide excellent service life, that keeps the machine in the field longer. Long Undercarriage. The long (L) undercarriage maximizes stability and lift capacity. This long, wide, and sturdy undercarriage offers a very stable work platform. Booms and Sticks. 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. Reach Boom. The reach boom features an optimum design that maximizes digging envelopes. R2.9B Stick. The R2.9B stick is versatile and used in a variety of applications.

Serviceability Simplified service and maintenance save you time and money.
Extended Service Intervals. Extended service and maintenance intervals reduce service time and increase machine availability. Use of oil-free bearing extends front linkage greasing interval to 1000 hours, except in the bucket area, which has been extended to 100 hours. Ground-Level Maintenance. For operator convenience, daily maintenance areas can be easily reached from ground level. Pre-Start Monitoring System. This system allows the operator to check coolant, hydraulic oil and engine oil levels from the monitor inside the cab.
Anti-Skid “Pressed-Star” Plate. The top of the storage box and surface of the upper structure are covered with “pressed-star” plate to prevent the service person or operator from slipping during maintenance. Handrail and Steps. Larger handrails and steps make it easier for the operator to climb on and off the machine. Fan Guard. Engine radiator fan and oil cooler are completely enclosed by fine wire mesh, reducing the risk of injury. Greasing Points. A concentrated remote greasing block on the boom delivers grease to hard-to-reach locations.
Service Doors. Service doors are located on both sides of the upper structure. The doors make it easy to reach maintenance items such as the engine radiator or any hydraulic components from ground level. Openings are large and service doors latch in the full open position. Air Filter. The air filter features a doubleelement construction for superior cleaning efficiency. If the air cleaner plugs, a warning is displayed on the monitor screen inside the cab. Fuel-Water Separator. The water separator has a primary fuel filter element and is located in the radiator compartment for easy access from the ground.

Operator Station The 321C LCR operator workstation is quiet with ergonomic control placement and convenient adjustments, low lever and pedal effort, ergonomic seat design and highly efficient ventilation.
8
Cab Design. An enlarged cab with curved styling gives the operator a comfortable, spacious working environment and excellent visibility.
Skylight. The pop-up skylight provides improved upward visibility and opens easily with the assistance of a gas cylinder.
Sliding Door. The cab door slides alongside the cab and takes less space to open and close than a hinged door. This unique design allows the operator to easily get in and out of the cab when working against walls on job sites, even when attachments are added.
Windshields. The upper front windshield opens, closes, and stores below the roof of the operator with a one-touch action release system. Grips on the mid-lower portion of the front windshield assist in easy opening.
Monitor. New, compact monitor enhances viewing while displaying a variety of easy to read and understand languagebased information. Climate Control. The 321C LCR features a semi-automatic climate control with air intake system. The air conditioner is standard and adjusts temperature and flow.
Windows. The enlarged right-side window provides excellent visibility and isolates the operator from the hydraulic lines. The upper cab door window slides open, providing ventilation and allowing the operator to easily communicate with people on the work site.
