Prior to starting the machine, the system checks for low engine oil, hydraulic oil and engine coolant fluid levels and warns the operator through a color Liquid Crystal Display (LCD) monitor. The LCD monitor displays vital operating and performance information, in 29 different languages, for operator convenience.
The 314D provides a new cab design that allows a Falling Object Guard System (FOGS) or front windshield screen to be bolted directly to the cab, at the factory or in the field, enabling the machine to meet specifications and job site requirements. The cab shell is attached to the frame with viscous rubber cab mounts that dampen vibrations and sound levels to enhance operator comfort.
An optional Machine Security System (MSS) utilizes a programmable key, deterring theft, vandalism and unauthorized usage. MSS uses electronically coded keys selected by the customer to limit usage by individuals or time parameters.
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.
A two-stage control and one-touch low idle button maximize fuel efficiency and reduce 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.
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.
Accessible through the in-cab monitor, 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.
The boom and stick electronic regeneration circuit saves energy during boom-down and stick-in operation, increasing efficiency and lowering operating costs.
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.
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.
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. Idler and center guards (standard for LC option) are available to help maintain track alignment when traveling or working on slopes.
Track links are assembled and sealed with grease to decrease internal bushing wear and increase life by as much as 25 percent, when compared to dry seal undercarriages.
Travel motors with automatic speed selection let the 314D automatically change up and down from high and low speeds in a smooth, controlled manner.
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.
The boom is designed for maximum digging capability and is robotic welded to ensure consistent quality. This allows excellent all-around versatility and a large working envelope.
Three stick options are available to meet your application needs and increase performance and productivity. A new 2.8 m (9'2") intermediate stick is available to provide long reach and increased digging and lifting capability.
Caterpillar offers a variety of work tools, including hammers, thumbs, grapples, multi-processors, shears, pulverizers and vibratory compactors to fit your application needs. Additionally, a wide range of buckets are available to optimize machine performance. Auxiliary hydraulic and electrical lines are routed to the boom foot for easier installation of auxiliary hydraulic circuits, therefore reducing time, parts and cost required to add a work tool.
An optional hydraulic pin grabber coupler is available to pick up a wide variety of buckets and work tools without having to leave the cab, thus maximizing productivity.
The shorter tail swing and tighter front swing radius allow the operator to work safer and more efficiently on space restricted or congested job sites, focusing more on the work at hand and less on counterweight clearance.
The 314D CR/314D LCR features a compact radius design which makes it ideal for working in space restricted conditions such as close to buildings, against walls/fences/embankments, wooded residential lots, road contruction - limiting lane closures, logging roads or just generally "crowded" job sites. This is not just a "city" machine. The tail swing radius is just 1.48 m (4'10") with the standard counterweight as compared to 2.14 m (7'0") on the Cat 312D. When rotated 90 degrees and working over the side, a minimal amount of counterweight extends beyond the track width: 185 mm (7") of overhang with 600 mm (24") track shoes and standard counterweight. At the end of the day, there is significantly reduced risk of damage to the machine and any job site obstacles which equates to lower operating costs, better resale value, increased safety and more operator comfort.
Due to the 314D CR/314D LCR compact working envelope, operators can work confidently knowing that the counterweight will not swing into objects behind them.
The cab on the 314D CR/314D LCR is a comfortable place to work, with low sound levels, good viewing area and convenient access to the switches and controls. The 314D CR/314D LCR cab offers many of the same amenities and options found on the cab of the Cat 312D.
To further minimize the working envelope, the boom is repositioned more towards the center of the machine compared to a standard excavator. This reduces the front swing radius when the boom is pulled all the way up and the stick brought in completely.
Equipped with S·O·SSM sampling ports and test ports for hydraulics, engine oil and coolant for quick diagnostics. A test connection for the Cat Electronic Technician (Cat ET) service tool is now located in the cab, behind the seat.
A double-layered filter core in the radial seal air filter gives more efficient filtration. A warning is displayed on the monitor when dust accumulates above a preset level. This filter is conveniently located in the compartment behind the cab. An optional pre-cleaner is also available to extend filter life and reduce maintenance costs.
Capsule-type, hydraulic return filter is accessible from outside the tank and prevents contaminants from entering the system when changing the hydraulic oil.
Removable screens are located in front of the radiator and hydraulic cooler, reducing cleaning time and effort.
