Enhanced comfort, operation and visibility
The ergonomically designed operator station is spacious, quiet and comfortable, assuring high productivity during a long work day. All switches are located on the right-hand console for convenient access.Monitor
The monitor is a full color 400×234 pixels Liquid Crystal Display (LCD) graphic display. The monitor angle can be adjusted to minimize sun glare and has the capability of displaying information in Chinese and twenty-six other languages.Joystick Control
Low effort, pilot operated joystick controls are designed to match the operator’s natural wrist and arm position for maximum comfort and minimum fatigue.Seat
The standard suspension seat provides a variety of adjustments to suit the operator’s size and weight including fore/aft, height and weight. Wide adjustable armrests and a retractable seat belt are also included.Console
The consoles feature a simple, functional design to reduce operator fatigue, ease of switch operation and excellent visibility. Both consoles have attached armrests with height adjustments.Cab Exterior
The cab shell features thick steel tubing along the bottom perimeter of the cab, improving resistance to fatigue and vibration.Cab Mounts
The cab shell is attached to the frame with viscous rubber cab mounts, which dampen vibrations and sound levels while enhancing operator comfort.Windows
To maximize visibility, all glass is affixed directly to the cab, eliminating window frames. The upper front windshield opens, closes and stores on the roof above the operator with a one-touch action release system.Wipers
Pillar-mounted wipers increase the operator’s viewing area and offer continuous and intermittent modes.
Delivering the most work per liter/gallon of fuel consumed
The Cat C4.2 engine with ACERT Technology optimizes performance and meets U.S. EPA Tier 3 and EU Stage IIIA regulations. In conjunction with integrated electronics, ACERT Technology reduces emissions during the combustion process by using advanced technology in the air and fuel systems. The Cat C4.2 engine delivers exceptional power, allowing more hydraulic pressure to drive productivity and reduce your cost per ton of material moved.Automatic Engine Control and Fuel Delivery
A two-stage control with one-touch command maximizes fuel efficiency and reduces sound levels. Fuel delivery is managed by the ADEM™ A4 Engine Controller for the best performance per liter (gallon) of fuel used. Flexible fuel mapping allows the engine to respond quickly to varying application needs.Crankshaft and Pistons
A forged, one-piece, induction hardened crankshaft enhances balance, decreases vibration and improves abrasion resistance. Heat resistant, aluminum alloy pistons have a short compression height for greater efficiency and longer life.Economy Mode
Available as standard, economy mode allows you to balance the demands of performance and fuel economy while maintaining the breakout forces and lift capacity enjoyed at standard power.
Low effort and precise control for highly efficient performance
Outstanding Performance Boom and Stick Regeneration Circuit
The 313D hydraulic system is designed for high efficiency and performance. Auxiliary hydraulic and electrical lines are routed to the boom foot making installation of hydraulic circuits much easier. This compact design utilizes short tubes and lines, reducing friction and pressure drops, resulting in a more efficient use of power.
- Hydraulic snubbers at the rod end of the boom cylinders and both ends of the stick cylinders cushion shock, reduce sound and increase cylinder life.
- Flow is reduced to a minimum when controls are in neutral to reduce fuel consumption and extend component life.
- Electronic Under Speed Control electronically adjusts pump output to not exceed engine power, preventing the need to reserve engine power to avoid engine stalls.
- Hydraulic Cross-Sensing System uses two hydraulic pumps up to 100 percent of engine power under all operating conditions, improving productivity with faster implement speeds and quicker, stronger pivot turns.
The boom and stick regeneration circuit saves energy during boom-down and stick-in operation, increasing efficiency and lowering operating costs.Easy Operation
Work mode and power mode switches have been eliminated making full power available at all times. Operators do not need to learn different modes, an automatic boom and swing priority function automatically selects the best mode based on joystick movement.
Undercarriage and Structures
Strong, stable and easy to maneuver
Caterpillar uses advanced engineering and software to analyze all structures, creating a durable, reliable machine for the toughest applications. More than 70 percent of the structural welds are robotic and achieve additional penetration over manual welds. These structural components and undercarriage are the backbone of the machine’s durability.Carbody Design
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.Grease Lubricated Track
Grease lubricated track seals protect the track link and deliver long track link pin and bushing inner wear.Travel Motors
Travel motors with automatic speed selection let the 313D automatically change up and down from high and low speeds in a smooth, controlled manner.
Reliable, durable and versatile
Built for performance and long service life, Cat booms and sticks are welded, box-section structures with thick multi-plate high strength steel fabrications. Service intervals are extended with self-lubricating bearings that resist corrosion and galling for superior durability.Heavy Duty Stick
A 2.5 m heavy duty stick has additional plates, new forged parts and welded joints for increased durability, digging force and lifting capability.Boom
A 4.65 m one-piece, heavy duty boom features parts made from a new forging pattern and additional, thicker plates. A light attached to the left side offers improved visibility in dark and low-light conditions.
More options for more work
Cat Buckets and Cat Ground Engaging Tools (GET) are designed and matched to the machine ensuring optimal performance and fuel consumption. They are built to Caterpillar specifications guaranteeing quality and durability, whatever the application.General Duty Buckets
General Duty buckets have been designed for machines digging in low-impact, moderately abrasive materials such as dirt, loam, gravel and clay.Severe Duty Buckets
Severe duty are best suited to highly abrasive applications such as shot rock and granite.
Service and Maintenance
Simplified service and maintenance features save you time and money
Ground Level Service
The design and layout of the 313D was made with the service technician in mind. Many service locations are easily accessible at ground level allowing service and maintenance to get completed quickly and efficiently.Pump Compartment
A service door on the right side of the upper structure allows ground-level access to the pump, pilot filter, drain filter, and the engine oil filter.Radiator Compartment
The left service door allows easy access to the engine radiator, oil cooler, air-to-air-after-cooler, water separator and 3rd fuel filter. A reserve tank and drain cock are attached to the radiator for simplified maintenance. The air filter features a double-element construction for superior cleaning efficiency. When the air cleaner plugs, a warning is displayed on the monitor screen inside the cab.Capsule Filter
The hydraulic return filter, a capsule filter, is situated outside the hydraulic tank. This filter prevents contaminants from entering the system when hydraulic oil is changed and keeps the operation clean.Greasing Points
A concentrated remote greasing block on the boom delivers grease to hard-to-reach locations on the front.Fan Guard
Engine radiator fan is completely enclosed by fine wire mesh, reducing the risk of an accident.Anti-Skid Plate
Anti-skid plate covers top of storage box and upper structure to prevent slipping during maintenance.Diagnostics and Monitoring
The 313D is equipped with S∙O∙SSM sampling ports and hydraulic test ports for the hydraulic system, engine oil, and for coolant. A test connection for the Cat Electronic Technician (Cat ET) service tool is located behind the cab.Extended Service Interval
313D service and maintenance intervals have been extended to reduce machine service time and increase machine availability.
