Controls The right and left joystick (1) consoles can be adjusted to meet individual preferences improving operator comfort and productivity during the course of a day With the touch of a button one-touch idle reduces engine speed to help save fuel touch it again or move the joystick and the machine returns to normal operating level

Monitor The 312E is equipped with a 7 LCD (Liquid Crystal Display) monitor (2) that is 40 bigger than the previous modelrsquos with higher resolution for better visibility In addition to an improved keypad and added functionality itrsquos programmable to provide information in a choice of 44 languages to support todayrsquos diverse workforce

An ldquoEngine Idle Shutdownrdquo setting accessible through the monitor allows owners and operators to specify how long the machine should idle before shutting down the engine which can save significant amounts of fuel

The image of the rearview camera is displayed directly on the monitor which will help keep you focused on the job at hand

Power Supply Two 12-volt power supply sockets are located near key storage areas for charging electronic devices such as an MP3 player and cell phone

Storage Storage spaces are located in the front rear and side consoles A dedicated space near the auxiliary power supply holds MP3 players and cell phones The drink holder accommodates large mugs with handles and a shelf behind the seat stores large lunch or toolboxes

Automatic Climate Control The climate control system features five air outlets with positive filtered ventilation which makes working in the heat and cold much more pleasant

4

Hydraulics Power to move more dirt rock and debris with speed and precision

Main Control Valve and Auxiliary Valves The 312E uses a high-pressure system to tackle the toughest of work in short order The machine features a highly effi cient and simple main control valve to improve fuel consumption it also allows for greater tool versatility

Electric Boom Regeneration System The 312E regenerates the flow of oil from the head end of the boom cylinder to the rod end of the boom cylinder during a boom down operation to save energy which helps improve fuel efficiency It is optimized for any dial speed setting being used by the operator which results in less pressure loss for higher controllability more productivity and lower operating costs

5

Structures amp Undercarriage Built to work in rugged environments

Frame The upper frame includes reinforced mountings to support the Roll-Over Protective Structure (ROPS) cab the lower frame is reinforced to increase component durability

Undercarriage Long undercarriage supports various work applications The track rollers are a double solid-pin-type design to improve reliability compared to the single solid-pin-type design A segmented two-piece guiding guard is now offered to help maintain track alignment and improve performance in multiple applications

Counterweight Built with an integrated rearview camera housing the counterweight comes with integrated links to enable easy removal for maintenance or shipping

6

Front Linkage Made for high stress and long service life

Booms and Sticks The 312E is offered with a reach boom and three stick configurations R25 m (82) R28 m (92) and R30 m (910) Also a new thumb-ready stick with factory brackets and structural reinforcement to attach a Cat hydraulic thumb to the machine is an available option Each boom and stick is built with internal baffle plates for added durability and each undergoes ultrasound inspection to ensure weld quality and reliability

Reach configuration balances digging force and bucket capacity It covers all applications this size of machine was designed to take on such as digging loading trenching and working with hydraulic tools

Large box-section structures with thick multi-plate fabrications castings and forgings are used in high-stress areas such as the boom nose boom foot boom cylinder and stick foot to improve durability Also the front linkage pinsrsquo inner bearing surfaces are welded with a self-lubricated bearing used to extend service intervals and increase uptime

Quick Couplers Quick couplers allow one person to change work tools in seconds for maximum performance and flexibility on a job site One machine can move rapidly from task to task and a fleet of similarly equipped machines can share a common work tool inventory

Cat Center-Locktrade Pin Grabber Coupler Center-Lock is the pin grabber style of coupler featuring a patented locking system A highly visible lock clearly shows the operator when the coupler is engaged or disengaged from the bucket or work tool

Buckets Cat buckets are designed as an integral part of the 312E system and feature new geometry for better performance The leading edge has been repositioned resulting in more effi cient filling and better operator control for greatly improved productivity Greater wear coverage in the corners greater side cutter and sidebar protector coverage and a new lift eye design are features of Next Generation buckets All benefits are captured in a new bucket line with a new bucket naming convention

8

Durability Categories Suitable for Any Situation Caterpillar offers standard bucket categories for excavators Each category is based on intended bucket durability when used in recommended applications and materials Each bucket durability is available as pin-on or can be used with a quick coupler

General Duty (GD) GD buckets are for digging in low-impact low-abrasion material such as dirt loam and mixed compositions of dirt and fi ne gravel

Severe Duty (SD) SD buckets are for higher abrasion conditions such as well shot granite and caliche Red area on bucket image illustrates additional protection against wear as compared to a GD bucket

Specialty Buckets In addition to standard bucket categories specialty bucket styles are available for the 312E each with a different purpose

bull Ditch Cleaning and Tilt buckets are for cleaning ditches slope grading and other fi nish work

bull Wide Tip buckets are for low impact material where leaving a smoother floor and minimal spillage are necessary

Hydraulic Kits Caterpillar offers field-installed hydraulic kits that are uniquely designed to integrate Cat Work Tool attachments with Cat excavators Hoses and tubes are pre-made pre-shaped and pre-painted to make installation quick and easy

Sustainability Generations ahead in every way

bull The C44 ACERT engine along with the Cat Clean Emissions Module (CEM) meets US EPA Tier 4 Interim emission standards

bull Even when operating in high horsepower and high production applications the 312E performs a similar amount of work while burning less fuel than the previous D Series model This means more efficiency less resources consumed and fewer emissions

bull The 312E has the flexibility of running on either ultra-low-sulfur diesel (ULSD) fuel with 15 ppm of sulfur or less or biodiesel (B20) fuel blended with ULSD that meets ASTM 6751 or EN 14214 standards

bull An overfill indicator rises when the fuel tank is full to help service technicians avoid spilling

bull The QuickEvactrade option ensures fast easy and secure changing of engine and hydraulic oil

bull The 312E is built to be rebuilt with major structures and components capable of being remanufactured to reduce waste and replacement costs

bull An efficient engine oil filter eliminates the need for painted metal cans and aluminum top plates The cartridge-style spin-on housing enables the internal filter to be separated and replaced the used internal element can be incinerated to help reduce waste

bull The 312E is an efficient productive machine thatrsquos designed to conserve our natural resources for generations ahead

Durability Categories Suitable for Any Situation Caterpillar offers standard bucket categories for excavators Each category is based on intended bucket durability when used in recommended applications and materials Each bucket durability is available as pin-on or can be used with a quick coupler

General Duty (GD) GD buckets are for digging in low-impact low-abrasion material such as dirt loam and mixed compositions of dirt and fi ne gravel

Severe Duty (SD) SD buckets are for higher abrasion conditions such as well shot granite and caliche Red area on bucket image illustrates additional protection against wear as compared to a GD bucket

Specialty Buckets In addition to standard bucket categories specialty bucket styles are available for the 312E each with a different purpose

bull Ditch Cleaning and Tilt buckets are for cleaning ditches slope grading and other fi nish work

bull Wide Tip buckets are for low impact material where leaving a smoother floor and minimal spillage are necessary

Hydraulic Kits Caterpillar offers field-installed hydraulic kits that are uniquely designed to integrate Cat Work Tool attachments with Cat excavators Hoses and tubes are pre-made pre-shaped and pre-painted to make installation quick and easy

Comprehensive Product Support All Cat Work Tools are backed up by a world-wide network of well-stocked parts depots and highly experienced service and support personnel

Integrated Technologies Solutions that make work easier and more efficient

Catreg Grade Control Depth and Slope This optional system combines traditional machine control and guidance with standard factory-installed and calibrated components making the system ready to go to work the moment it leaves the factory The system utilizes internal front linkage sensors ndash well protected from the harsh working environment ndash to give operators real-time bucket tip position information through the cab monitor (1) which minimizes the need and cost for traditional grade checking and enhances job site safety It also helps the operator complete jobs in fewer cycles which means less fuel use Cat dealers can upgrade the system to full three-dimensional control by adding proven Cat AccuGradetrade positioning technologies including GPS and Universal Total Station (UTS)

Cat Product Link This optional system is deeply integrated into the machine monitoring system and is designed to help customers improve their overall fl eet management effectiveness Events and diagnostic codes as well as hours fuel consumption idle time machine location and other detailed information are transmitted to a secure web based application (2 and 3) called VisionLinktrade which uses powerful tools to communicate to users and dealers

ROPS Cab The ROPS-certified cab (1) allows an Operator Protective Guard to be bolted directly to it

Sound Proofing Improved sealing and cab roof lining lower noise levels inside the cab significantly during machine operation

Anti-Skid Plates The surface of the upper structure and the top of the storage box area are covered with anti-skid plates to help prevent service personnel and operators from slipping during maintenance

Steps Hand and Guard Rails Steps on the track frame and storage box along with extended hand rail and optional guard rail to the upper deck enable operators to securely work on the machine

Time Delay Lights When the light switch is on cab and boom lights will illuminate to enhance visibility after the engine start key has been turned off

High Intensity Discharge (HID) Lights Halogen lights are standard but they can be upgraded to HID for greater visibility

Windows The 7030 split configuration features an upper window equipped with handles on the top and both sides so the operator can slide it to store in the ceiling The lower window is removable and can be stored on the left wall of the cab shell The large skylight provides great overhead visibility excellent natural lighting and good ventilation The skylight can be opened completely to become an emergency exit

Wiper System A lower wiper is available as an option to maximize visibility in poor weather conditions The lower wiper motor is integrated to the upper frame so it doesnrsquot obstruct the forward view

Monitor Warning System The machine features a buzzer in the monitor that tells customers when critical events like plugged filters or low hydraulic pressure need to be immediately addressed

Rearview Camera An optional rearview camera (2) is housed in the counterweight The image projects through the cab monitor (3) to give the operator a clear view of what is behind the machine

Sustainability Generations ahead in every way

bull The C44 ACERT engine along with the Cat Clean Emissions Module (CEM) meets US EPA Tier 4 Interim emission standards

bull Even when operating in high horsepower and high production applications the 312E performs a similar amount of work while burning less fuel than the previous D Series model This means more efficiency less resources consumed and fewer emissions

bull The 312E has the flexibility of running on either ultra-low-sulfur diesel (ULSD) fuel with 15 ppm of sulfur or less or biodiesel (B20) fuel blended with ULSD that meets ASTM 6751 or EN 14214 standards

bull An overfill indicator rises when the fuel tank is full to help service technicians avoid spilling

bull The QuickEvactrade option ensures fast easy and secure changing of engine and hydraulic oil

bull The 312E is built to be rebuilt with major structures and components capable of being remanufactured to reduce waste and replacement costs

bull An efficient engine oil filter eliminates the need for painted metal cans and aluminum top plates The cartridge-style spin-on housing enables the internal filter to be separated and replaced the used internal element can be incinerated to help reduce waste

bull The 312E is an efficient productive machine thatrsquos designed to conserve our natural resources for generations ahead

Integrated Technologies Solutions that make work easier and more efficient

Catreg Grade Control Depth and Slope This optional system combines traditional machine control and guidance with standard factory-installed and calibrated components making the system ready to go to work the moment it leaves the factory The system utilizes internal front linkage sensors ndash well protected from the harsh working environment ndash to give operators real-time bucket tip position information through the cab monitor (1) which minimizes the need and cost for traditional grade checking and enhances job site safety It also helps the operator complete jobs in fewer cycles which means less fuel use Cat dealers can upgrade the system to full three-dimensional control by adding proven Cat AccuGradetrade positioning technologies including GPS and Universal Total Station (UTS)

Cat Product Link This optional system is deeply integrated into the machine monitoring system and is designed to help customers improve their overall fl eet management effectiveness Events and diagnostic codes as well as hours fuel consumption idle time machine location and other detailed information are transmitted to a secure web based application (2 and 3) called VisionLinktrade which uses powerful tools to communicate to users and dealers

Serviceability Fast easy and safe access built in

Service Doors Wide service doors feature sturdier hinges and latches and a new screen design to help prevent debris entry a one-piece hood (1) provides easier access to the engine and cooling compartments

Compartments The radiator (2) pump (3) and air cleaner compartments provide easy access to major components The fresh air filter is located on the side of the cab to make it easy to reach and replace as needed

Other Service Benefits The water separator with water level sensor has a primary fuel filter element located in the pump compartment near ground level the electric priming pump is mounted before the primary filter base and is easy to service compared to a traditional hand-priming pump

The fuel tank features a remote drain cock located in the pump compartment to make it easy to remove water and sediment during maintenance

The engine oil check gauge is situated in front of the engine compartment for easy access and a uniquely designed drain cock helps prevent spills

ROPS Cab The ROPS-certified cab (1) allows an Operator Protective Guard to be bolted directly to it

Sound Proofing Improved sealing and cab roof lining lower noise levels inside the cab significantly during machine operation

Anti-Skid Plates The surface of the upper structure and the top of the storage box area are covered with anti-skid plates to help prevent service personnel and operators from slipping during maintenance

Steps Hand and Guard Rails Steps on the track frame and storage box along with extended hand rail and optional guard rail to the upper deck enable operators to securely work on the machine

Time Delay Lights When the light switch is on cab and boom lights will illuminate to enhance visibility after the engine start key has been turned off

High Intensity Discharge (HID) Lights Halogen lights are standard but they can be upgraded to HID for greater visibility

Windows The 7030 split configuration features an upper window equipped with handles on the top and both sides so the operator can slide it to store in the ceiling The lower window is removable and can be stored on the left wall of the cab shell The large skylight provides great overhead visibility excellent natural lighting and good ventilation The skylight can be opened completely to become an emergency exit

Wiper System A lower wiper is available as an option to maximize visibility in poor weather conditions The lower wiper motor is integrated to the upper frame so it doesnrsquot obstruct the forward view

Monitor Warning System The machine features a buzzer in the monitor that tells customers when critical events like plugged filters or low hydraulic pressure need to be immediately addressed

Rearview Camera An optional rearview camera (2) is housed in the counterweight The image projects through the cab monitor (3) to give the operator a clear view of what is behind the machine

Sustainability Generations ahead in every way

bull The C44 ACERT engine along with the Cat Clean Emissions Module (CEM) meets US EPA Tier 4 Interim emission standards

bull Even when operating in high horsepower and high production applications the 312E performs a similar amount of work while burning less fuel than the previous D Series model This means more efficiency less resources consumed and fewer emissions

bull The 312E has the flexibility of running on either ultra-low-sulfur diesel (ULSD) fuel with 15 ppm of sulfur or less or biodiesel (B20) fuel blended with ULSD that meets ASTM 6751 or EN 14214 standards

bull An overfill indicator rises when the fuel tank is full to help service technicians avoid spilling

bull The QuickEvactrade option ensures fast easy and secure changing of engine and hydraulic oil

bull The 312E is built to be rebuilt with major structures and components capable of being remanufactured to reduce waste and replacement costs

bull An efficient engine oil filter eliminates the need for painted metal cans and aluminum top plates The cartridge-style spin-on housing enables the internal filter to be separated and replaced the used internal element can be incinerated to help reduce waste

bull The 312E is an efficient productive machine thatrsquos designed to conserve our natural resources for generations ahead

ROPS Cab The ROPS-certified cab (1) allows an Operator Protective Guard to be bolted directly to it

Sound Proofing Improved sealing and cab roof lining lower noise levels inside the cab significantly during machine operation

Anti-Skid Plates The surface of the upper structure and the top of the storage box area are covered with anti-skid plates to help prevent service personnel and operators from slipping during maintenance

Steps Hand and Guard Rails Steps on the track frame and storage box along with extended hand rail and optional guard rail to the upper deck enable operators to securely work on the machine

Time Delay Lights When the light switch is on cab and boom lights will illuminate to enhance visibility after the engine start key has been turned off

High Intensity Discharge (HID) Lights Halogen lights are standard but they can be upgraded to HID for greater visibility

Windows The 7030 split configuration features an upper window equipped with handles on the top and both sides so the operator can slide it to store in the ceiling The lower window is removable and can be stored on the left wall of the cab shell The large skylight provides great overhead visibility excellent natural lighting and good ventilation The skylight can be opened completely to become an emergency exit

Wiper System A lower wiper is available as an option to maximize visibility in poor weather conditions The lower wiper motor is integrated to the upper frame so it doesnrsquot obstruct the forward view

Monitor Warning System The machine features a buzzer in the monitor that tells customers when critical events like plugged filters or low hydraulic pressure need to be immediately addressed

Rearview Camera An optional rearview camera (2) is housed in the counterweight The image projects through the cab monitor (3) to give the operator a clear view of what is behind the machine

Sustainability Generations ahead in every way

bull The C44 ACERT engine along with the Cat Clean Emissions Module (CEM) meets US EPA Tier 4 Interim emission standards

bull Even when operating in high horsepower and high production applications the 312E performs a similar amount of work while burning less fuel than the previous D Series model This means more efficiency less resources consumed and fewer emissions

bull The 312E has the flexibility of running on either ultra-low-sulfur diesel (ULSD) fuel with 15 ppm of sulfur or less or biodiesel (B20) fuel blended with ULSD that meets ASTM 6751 or EN 14214 standards

bull An overfill indicator rises when the fuel tank is full to help service technicians avoid spilling

bull The QuickEvactrade option ensures fast easy and secure changing of engine and hydraulic oil

bull The 312E is built to be rebuilt with major structures and components capable of being remanufactured to reduce waste and replacement costs

bull An efficient engine oil filter eliminates the need for painted metal cans and aluminum top plates The cartridge-style spin-on housing enables the internal filter to be separated and replaced the used internal element can be incinerated to help reduce waste

bull The 312E is an efficient productive machine thatrsquos designed to conserve our natural resources for generations ahead

ROPS Cab The ROPS-certified cab (1) allows an Operator Protective Guard to be bolted directly to it

Sound Proofing Improved sealing and cab roof lining lower noise levels inside the cab significantly during machine operation

Anti-Skid Plates The surface of the upper structure and the top of the storage box area are covered with anti-skid plates to help prevent service personnel and operators from slipping during maintenance

Steps Hand and Guard Rails Steps on the track frame and storage box along with extended hand rail and optional guard rail to the upper deck enable operators to securely work on the machine

Time Delay Lights When the light switch is on cab and boom lights will illuminate to enhance visibility after the engine start key has been turned off

High Intensity Discharge (HID) Lights Halogen lights are standard but they can be upgraded to HID for greater visibility

Windows The 7030 split configuration features an upper window equipped with handles on the top and both sides so the operator can slide it to store in the ceiling The lower window is removable and can be stored on the left wall of the cab shell The large skylight provides great overhead visibility excellent natural lighting and good ventilation The skylight can be opened completely to become an emergency exit

Wiper System A lower wiper is available as an option to maximize visibility in poor weather conditions The lower wiper motor is integrated to the upper frame so it doesnrsquot obstruct the forward view

Monitor Warning System The machine features a buzzer in the monitor that tells customers when critical events like plugged filters or low hydraulic pressure need to be immediately addressed

Rearview Camera An optional rearview camera (2) is housed in the counterweight The image projects through the cab monitor (3) to give the operator a clear view of what is behind the machine

Sustainability Generations ahead in every way

bull The C44 ACERT engine along with the Cat Clean Emissions Module (CEM) meets US EPA Tier 4 Interim emission standards

bull Even when operating in high horsepower and high production applications the 312E performs a similar amount of work while burning less fuel than the previous D Series model This means more efficiency less resources consumed and fewer emissions

bull The 312E has the flexibility of running on either ultra-low-sulfur diesel (ULSD) fuel with 15 ppm of sulfur or less or biodiesel (B20) fuel blended with ULSD that meets ASTM 6751 or EN 14214 standards

bull An overfill indicator rises when the fuel tank is full to help service technicians avoid spilling

bull The QuickEvactrade option ensures fast easy and secure changing of engine and hydraulic oil

bull The 312E is built to be rebuilt with major structures and components capable of being remanufactured to reduce waste and replacement costs

bull An efficient engine oil filter eliminates the need for painted metal cans and aluminum top plates The cartridge-style spin-on housing enables the internal filter to be separated and replaced the used internal element can be incinerated to help reduce waste

bull The 312E is an efficient productive machine thatrsquos designed to conserve our natural resources for generations ahead

Sustainability Generations ahead in every way

bull The C44 ACERT engine along with the Cat Clean Emissions Module (CEM) meets US EPA Tier 4 Interim emission standards

bull Even when operating in high horsepower and high production applications the 312E performs a similar amount of work while burning less fuel than the previous D Series model This means more efficiency less resources consumed and fewer emissions

bull The 312E has the flexibility of running on either ultra-low-sulfur diesel (ULSD) fuel with 15 ppm of sulfur or less or biodiesel (B20) fuel blended with ULSD that meets ASTM 6751 or EN 14214 standards

bull An overfill indicator rises when the fuel tank is full to help service technicians avoid spilling

bull The QuickEvactrade option ensures fast easy and secure changing of engine and hydraulic oil

bull The 312E is built to be rebuilt with major structures and components capable of being remanufactured to reduce waste and replacement costs

bull An efficient engine oil filter eliminates the need for painted metal cans and aluminum top plates The cartridge-style spin-on housing enables the internal filter to be separated and replaced the used internal element can be incinerated to help reduce waste

bull The 312E is an efficient productive machine thatrsquos designed to conserve our natural resources for generations ahead

Sustainability Generations ahead in every way

bull The C44 ACERT engine along with the Cat Clean Emissions Module (CEM) meets US EPA Tier 4 Interim emission standards

bull Even when operating in high horsepower and high production applications the 312E performs a similar amount of work while burning less fuel than the previous D Series model This means more efficiency less resources consumed and fewer emissions

bull The 312E has the flexibility of running on either ultra-low-sulfur diesel (ULSD) fuel with 15 ppm of sulfur or less or biodiesel (B20) fuel blended with ULSD that meets ASTM 6751 or EN 14214 standards

bull An overfill indicator rises when the fuel tank is full to help service technicians avoid spilling

bull The QuickEvactrade option ensures fast easy and secure changing of engine and hydraulic oil

bull The 312E is built to be rebuilt with major structures and components capable of being remanufactured to reduce waste and replacement costs

bull An efficient engine oil filter eliminates the need for painted metal cans and aluminum top plates The cartridge-style spin-on housing enables the internal filter to be separated and replaced the used internal element can be incinerated to help reduce waste

bull The 312E is an efficient productive machine thatrsquos designed to conserve our natural resources for generations ahead
