315 Hydraulic Excavator

315 Hydraulic Excavator

Overview

The Cat® 315 excavator offers superior performance in a compact design. Standard, easy-to-use Cat technologies boost operator efficiencies and improve jobsite productivity while a large, ergonomic cab provides a comfortable working environment. Combined with simplified maintenance points, the 315 keeps you working, quickly and efficiently.

High Performance and Productivity
  • Increase productivity by up to eight percent over the 315F.
  • Work confidently in space-restricted areas. Dig, swing, and dump within a working space of 3.96 m (12 ft 11 in).
  • Easily work on slopes and move around your jobsite with 10 percent more swing torque and 14 percent more drawbar pull.
Boost Efficiency and Productivity with Cat Technologies
  • Boost productivity up to 45 percent versus traditional grading with the standard Cat GRADE with 2D system ̶ includes indicate-only and laser capability.
  • Dig with guidance to depth, slope, and horizontal distance to grade. You can set up to four different depth and slope targets to help save time and money.
Work in Comfort in the All-New Cab
  • Increase operator productivity with an all-new, 13 percent larger cab. Comfort, Deluxe, and Premium cab options vary by region.
  • The Comfort cab is equipped with a mechanical suspension seat. The Deluxe seat is heated and air adjustable while the Premium seat is heated and cooled and adjusts automatically.
Simple to Operate
  • Start the engine with the push of a button, a Bluetooth key fob, a smartphone app, or the unique Operator ID function.
  • Program your preferred power mode and joystick settings using your operator ID. The excavator will automatically remember your selections.
  • Navigate quickly on the standard high-resolution touchscreen monitor or with the aid of the jog dial control.
Lower Maintenance Costs
  • Expect up to 30 percent less maintenance costs than the 315F.
  • Quickly check and service your machine with all daily maintenance points accessible from ground level.
  • Check the engine oil level quickly and safely from the ground. Fill and check engine oil on top of the machine with a conveniently located second dipstick.
Safety
  • Access all daily maintenance points from ground level – no need for you to climb on top of the machine.
  • The standard ROPS cab meets ISO 12117-2:2008 requirements.
  • Smaller cab pillars, larger windows, and a wider skylight hatch provide 60 percent greater vertical visibility.
High Performance and Productivity
  • Increase productivity by up to eight percent over the 315F.
  • Work confidently in space-restricted areas. Dig, swing, and dump within a working space of 3.96 m (12 ft 11 in).
  • Easily work on slopes and move around your jobsite with 10 percent more swing torque and 14 percent more drawbar pull.
  • The advanced hydraulic system provides the optimum balance of power and efficiency while giving you the control you need for precise digging requirements.
  • Smart mode meets your power needs by automatically matching engine and hydraulic power to digging conditions.
  • Get higher production in demanding applications, easier penetration into piles, and faster cycle times with Cat® Advansys™ bucket tips. Quickly change tips with a simple lug wrench instead of a hammer or special tool, improving safety and uptime.
  • Auxiliary hydraulic options give you the versatility to use a wide range of Cat attachments.
  • The Cat C3.6 engine meets U.S. EPA Tier 4 Final, EU Stage V, and Japan 2014 (Tier 4 Final) emission standards.
  • Don’t let the temperature stop you from working. The 315 has a standard high-ambient temperature capability of 52° C (125° F) without de-rate and cold-start capability of -25° C (-13° F).
Boost Efficiency and Productivity with Cat Technologies
  • Boost productivity up to 45 percent versus traditional grading with the standard Cat GRADE with 2D system ̶ includes indicate-only and laser capability.
  • Dig with guidance to depth, slope, and horizontal distance to grade. You can set up to four different depth and slope targets to help save time and money.
  • Standard 2D E-fence prevents your machine from moving outside operator-defined parameters.
  • Achieve precise load targets and increase loading efficiency with standard Cat PAYLOAD which provides on-the-go weighing and real-time estimates of your payload without swinging.
  • Combine Payload with VisionLink® and remotely manage your production targets.
  • Upgrade to Cat GRADE with Advanced 2D to create and edit grade designs with ease on a second, high-resolution 254 mm (10 in) touchscreen monitor.
  • Upgrade to Cat GRADE with 3D to create and edit designs with ease and see the front linkage’s full range of motion on a second high-resolution 254 mm (10 in) touch screen monitor. Use the machine’s onboard cell technology to quickly connect to 3D services like TCC or VRS.
  • Standard Product Link™ automatically and accurately collects data from your connected assets – any type and any brand. Information such as location, hours, fuel usage, productivity, idle time, maintenance alerts, diagnostic codes, and machine health can be viewed online through web and mobile applications.
  • Improve your accuracy and safety – Add a new Cat Tiltrotator system upgrade with factory-fit joysticks. The system allows a Tiltrotator to work with standard Cat 2D Grade and E-Fence; it uses the standard cab monitor to display the tool and engage its SecureLock™ so you don’t need spend money on an extra monitor.
Work in Comfort in the All-New Cab
  • Increase operator productivity with an all-new, 13 percent larger cab. Comfort, Deluxe, and Premium cab options vary by region.
  • The Comfort cab is equipped with a mechanical suspension seat. The Deluxe seat is heated and air adjustable while the Premium seat is heated and cooled and adjusts automatically.
  • Get in and out of the cab easier using the tip-up left console available in the deluxe and premium cabs.
  • Advanced viscous mounts reduce cab vibration.
  • Control the excavator comfortably with easy-to-reach controls all located in front of you.
  • Stow your gear with plenty of in-cab storage beneath and behind the seat, overhead, and in the consoles. A cup holder, document holder, and coat hook are also provided.

  • Program your preferred power mode and joystick settings using your operator ID. The excavator will automatically remember your selections.
  • Navigate quickly on the standard high-resolution touchscreen monitor or with the aid of the jog dial control.
  • The Cat Locator is a Bluetooth device that makes finding your attachments and other gear quick and easy. The excavator’s onboard Bluetooth reader or Cat App on your phone will locate the device automatically.
  • Save time and energy with work tool recognition. A simple shake of the attached tool confirms its identity ensuring all attachment settings are correct, so you can get to work quickly and efficiently.
  • Not sure how a function works or how to maintain your machine? Simply access the operator’s manual through the touch screen monitor.
Lower Maintenance Costs
  • Expect up to 30 percent less maintenance costs than the 315F.
