The engine is designed for high torque rise at middle rpm, a feature that is especially beneficial for heavy-duty use.
This three-stage control features a convenient one-touch command, maximizes fuel efficiency and reduces sound levels.
The oil level gauge, oil filter, fuel filter and priming pump are located on the right side of the upper structure for easy maintenance. The engine oil filter and fuel filter change intervals have been extended.
Eight balance, one-piece, forged crankshaft enhances balance and decreases vibration and is induction hardened to improve abrasion resistance.
Heat resistant aluminum alloy pistons have a short compression height, reducing weight and improving efficiency.
The 3046T engine has the best fuel consumption in this class of diesel engines. It features improved thermal efficiency and reduced friction resistance between piston and liners.
Air intake heating is standard on the 315C for easier cold starts.
The 315C hydraulic system was designed to provide a high level of efficiency. With all major components located close together, shorter tubes and lines are needed, resulting in less friction loss in the lines and reduced pressure drops.
Improves productivity with faster implement speeds and quicker, stronger pivot turns.
For simpler operation, work mode and power mode switches have been eliminated. Instead, the automatic boom and swing priority function selects the best mode, based on joystick movement.
Three types of stackable valves and one independent valve are available on the 315C and attached directly to the main control valve. Up to two stackable valves can be used in combination with the main control valve to provide a variety of different functions.
The 315C uses a boom and stick regeneration circuit to save energy during boom-down and stick-in operation.
The hydraulic system offers precise control to the 315C, reducing operator fatigue, improving operator effectiveness and efficiency, which ultimately translates into enhanced performance.
The auxiliary hydraulic valve is standard on the 315C for use with optional hydraulic circuits.
Hydraulic cylinder snubbers at the rod-end of boom cylinders and both ends of the stick cylinders cushion shocks, reduce sound and increase cylinder life.
The 315C 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 to deliver exceptional strength and service life.
Sealed and lubricated track rollers, carrier rollers and idlers provide excellent service life, keeping the machine in the field longer.
The rugged main frame is designed for maximum durability and efficient use of materials.
New grease lubricated seals protect the track link and deliver long track link pin and bushing inner wear life.
Automatic speed selection enables the machine to automatically change up and down from high and low speeds in a smooth, controlled manner.
An idler guard, which is integral to the track roller frame, is standard. This guard helps maintain track alignment while traveling or working on slopes.
Front linkage variations on the 315C allow for the use of one boom, three sticks and two bucket-types (excavation and heavy-duty rock). Using these combinations improves the general-purpose versatility of the 315C by suiting it to a diverse range of applications.
The boom on the 315C is designed to provide maximum digging capability. Caterpillar booms are manufactured with high-tensile steel for upper, lower and side plates and are robot welded for consistent quality.
Three sticks are available on the 315C. The customer's working envelope and bucket capacity needs determine their stick choice.
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.
High tensile strength steel is used in high-stress areas for excellent wear and shock resistance. The side plates are tapered to prevent contact of the bucket sidewalls during trenching operations.
The bucket linkage on the 315C includes the bucket cylinder, idler link and power links.
All 300 family excavator buckets are equipped with a bucket flop adjustment mechanism which allows the operator or serviceman to reduce the side play at the bucket to stick-nose connection.
New bearing technology has extended the front linkage greasing intervals for all bearings.
The 315C operator work station is quiet with ergonomic control placement and convenient adjustments, low lever and pedal effort, ergonomic seat design and highly efficient ventilation.
New, compact monitor enhances viewing while displaying a variety of easy-to-read and understand language-based information.
For simpler operation, work mode and power mode switches have been eliminated. Instead, the automatic boom and swing priority function selects the best mode, based on joystick movement.
Five hydraulic pump flows can be preset on the monitor, eliminating the need to adjust the flow every time a tool is changed and instantly providing the operator with the correct amount of flow for each tool. This feature is available with certain optional auxiliary hydraulic configurations.
Redesigned cab layout emphasizes simplicity and ease of use. Right-hand wall and console provides easy access to all switches, dials and controls.
A large rubber-covered footrest at the side of the travel pedals allows the foot to easily grip the pedal. The travel lever stroke and force have been enhanced to improve the 315C's fine controllability, making the machine easier to operate.
A new seat with a two-tone color offers two types of cushions - soft and firm - for operator comfort. The reclining knob is located at the right-side of the seat for easier reclining adjustment.
Fully automatic climate control adjusts temperature and flow and determines which air outlet is best in each situation.
A large polycarbonate skylight delivers excellent natural lighting and good ventilation. Standard sliding sunshade protects from direct sunlight.
The 315C cab is newly designed using asymmetrical steel tubing for improved resistance to fatigue and vibration. Falling Object Guard System (FOGS) may be bolted-on directly to the cab.
The cab shell is attached to the frame with improved viscous mounts, reducing vibration and sound.
With continuous and intermittent modes, the wiper is positioned on the right cab pillar to further improve the operator's viewing area.
The engine hood has been lowered, improving the operator's rear viewing area.
The upper front windshield opens, closes and stores on the roof above the operator. Grips on the mid-lower part of the front windshield make opening easy.
The lower front windshield glass features a rounded design that maximizes downward viewing. The windshield can be removed and stored at the left rear of the cab.
315C service and maintenance intervals have been extended to reduce machine service time and increase machine availability.
The left rear service door allows easy access to the engine radiator and the oil cooler. 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.
The design and layout of the 315C was made with the service technician in mind. Many service locations are easily accessible at ground level allowing critical maintenance to get done quickly and efficiently.
The oil cooler swings out horizontally for excellent cleaning.
A service door on the right side of the upper structure allows ground-level access to the pump and pilot filter.
The hydraulic return filter, a capsule filter, is situated inside the hydraulic tank but is easily accessed from outside the tank. This filter prevents contaminants from entering the system when hydraulic oil is changed, keeping the operation clean.
Anti-skid punched-star plate covers the top of the storage box and upper structure to prevent slipping during maintenance. The plate can be removed for cleaning.
Engine can be accessed from the upper structure or from under the machine. The engine and pump compartment are separated by a steel wall.
Larger handrails and steps assist operator in climbing on and off machine.
Grease lubricated seals protect the track link and deliver long track link pin and bushing inner wear life.
Engine radiator fan is completely enclosed by fine wire mesh, reducing the risk of an accident.
A concentrated remote greasing block on the boom delivers grease to hard-to-reach locations.
