Benefits & Features

Engine

A Powerful, Economical Solution

The Cat C3.4B engine meets Japan 2014 (Tier 4 Final) emission standards and provides plenty of power for the work you do without consuming a lot of fuel to do it. The engine is equipped with unique yet simple features like a turbo protector and maintenance-free emissions package that enhance service life – all to help keep your owning and operating costs to an absolute minimum.

Fuel-Saving Features

There are built-in features to help you manage how much fuel you use. One-touch low idle lets you reduce engine speed when the machine isn't working. Engine idle shutdown turns the engine off when it's been idling for more than the time that you set. Both contribute to saving fuel, reducing emissions, and extending your service intervals.

Proven Technology

    Every Japan 2014 (Tier 4 Final) engine is equipped with a combination of proven electronic, fuel, air, and aftertreatment components. Applying these technologies lets us meet your high expectations for productivity, fuel efficiency, reliability, and service life. The right technologies fine tuned for the right applications results in the following:
    • High performance across a variety of applications
    • Maximized uptime and reduced cost with world-class support from the Cat dealer network
    • Minimized impact of emission systems – designed to be transparent to the operator without requiring interaction
    • Durable designs with long life to overhaul
    • Less fuel consumption with minimized maintenance costs while providing the same great power and response.

Hydraulics

An Efficient, Reliable System

The 312F GC's hydraulic system is extremely reliable and features a load-sensing pump and control valve that calculate required hydraulic flow so you can meet your daily job requirements quickly and efficiently.

A Logical Layout

Like all Cat excavators, hydraulic components on the 312F GC are located close together in order to minimize the length of hydraulic lines. This logical layout leads to less pressure drops and more machine power for the work you need to do.

Maximum Versatility

When it comes to doing a variety of work, the machine's available high-pressure auxiliary and shovel crane function give you plenty of capability. An optional medium-pressure circuit (available from your local Cat dealer) adds more versatility.

Less Components, Less Maintenance

The addition of a pilot manifold in the valve block makes the system even easier to maintain because there is no need for a pilot pump, filter, or lines. Fewer components translate into less maintenance and lower owning and operating costs for you.

Operator Station

A Safe, Quiet Cab

The ROPS certified cab is not only a safety feature, but it is also a sound suppressor due to its special sealing and insulation. With the door and windows closed, you will experience a machine that's as quiet as the truck you drive to work.

A Great View

Ample glass gives you great views out front and to the side. A large rear window, aided by a low-profile engine, gives you excellent visibility out back. A large skylight provides great overhead visibility; it also serves as an emergency exit.

A Comfortable Seat

The seat includes a reclining back, upper and lower slide adjustments, and tilt angle adjustments to meet your needs for maximum comfort.

Controls Just for You

The right and left joystick consoles can be adjusted to improve your comfort and productivity during the course of a day. The right joystick features a button that will reduce engine speed when you are not working to help save fuel. Touch it once and speed reduces; touch it again and speed increases for normal operation.

An Easy-to-Use Monitor

The monitor displays critical information you need to operate efficiently. Not only can it memorize up to 10 different work tools, it's also programmable in up to 42 languages to meet today's diverse workforce.

A Cool and Warm Environment

The bi-level air conditioner system features multiple air outlets with filtered ventilation. Air flows on the floor, behind the seat, and in front of you to make your work in either hot or cold weather much more pleasant and productive.

Ample Storage and Auxiliary Power

Storage spaces are located in the front, rear, and side consoles of the cab. A drink holder accommodates a large mug, and a shelf behind the seat stores large lunch or toolboxes. Power supply sockets are available for charging your electronic devices like an MP3 player, a cell phone, or even a tablet.

Structures and Optional Undercarriage

Robust Frames

The 312F GC is a well-built machine that's designed to give you a long service life and excellent resale value. The upper frame includes special mountings made specially to support the heavy-duty cab; the lower frame is reinforced to enhance component durability so you can count on the machine doing the tough work you need to get done.

Durable Undercarriage

The machine's undercarriage works extremely well in various work applications and conditions. Plus its track shoes, links, rollers, idlers, and final drives are all built with high-tensile-strength steel for long-term durability.

Great Weight

The rigid 2.1 mt counterweight matches the machine's overall sleek appearance, and it provides plenty of balance for all of your work needs.

Simple Technologies

Link Technologies

This optional system is deeply integrated into the machine monitoring system and is designed to help customers improve their overall fleet management effectiveness. Events and diagnostic codes as well as hours, fuel consumption, idle time, machine location, and other detailed information are transmitted by Product Link™ Japan, which uses powerful tools to communicate to users and dealers.

Serviceability

Easy to Maintain

The 312F GC is a simple, compact, easy-to-maintain machine. You can reach most routine maintenance items like fluid taps and grease points from the safety and convenience of ground level. Wide service doors provide excellent access to the radiator, pump, air cleaner, and engine compartments; doors latch in place to make your service work simpler.

Room to Move

The diesel particulate filter used to capture emissions is compact and maintenance free. The engine doesn't need an air-to-air aftercooler, so that means more room to make cleaning cores easy. Also, the use of an easy-to-reach manual priming pump reduces the number of filters the machine needs. All of this leads to less complexity and lowers owning and operating costs for you.

More Service Benefits

The fuel tank features a remote drain located in the pump compartment to make it easy for you to remove water and sediment during routine maintenance. It also has an engine oil drain cock to make oil changes easy without any tools.

Safety

A Safe, Quiet Cab

The ROPS-certified cab provides you with a safe working environment. It also contributes to your comfort because it's attached to a reinforced frame with special viscous mounts that limit vibration and unnecessary sound. Add in special roof lining and sealing and you have a cab that's extremely quiet.

Great Views

Ample glass gives you great views out front and to the side. A large rear window, aided by a low-profile engine, gives you excellent visibility out back. The split-configuration windshield features an upper window equipped with handles so you can slide it to store in the ceiling; it also serves as an emergency exit.

Smart Lights

The 312F GC optional working lights provide all the illumination you will need. Plus the chassis light has a time-delay function that can be set to stay on up to five minutes after the engine has been turned off to help you safely exit the machine.

Secure Contacts

The surface of the upper structure and the top of the storage box area are covered with anti-skid plates to help prevent you from slipping during maintenance. Steps on the track frame and storage box along with extended hand rails to the upper deck enable you to securely work on the machine.
