Power to move your material with speed and precision

A Powerful, Efficient Design

When it comes to moving heavy material quickly and efficiently, you need hydraulic horsepower – the type of ground-breaking power the 374F can deliver. Major components like the pumps, the main control valve, and oil tank are positioned to reduce the effects of heat and hydraulic sound level on operators. And they are close together so shorter tubes and lines can be used. All of this leads to less friction loss, reduced pressure drops, and more power to the ground for the tons of work you need to get done.

Control Like No Other

Controllability is one of the main attributes of Cat excavators, and one of the key contributors to this is the main control valve. The 374F features the new ACS valve that’s designed to intelligently manage restrictions and flows. It opens slowly when your range of joystick lever movement is small and opens rapidly when movement is high. It puts flow exactly where you need it when you need it, which means you will experience much smoother operation, greater efficiency, and lower fuel consumption. The ACS valve also has a new automatic hydraulic oil warm-up function – a definite plus in putting your machine to work more quickly in cold weather conditions.

Auxiliary Hydraulics for Added Versatility

Auxiliary hydraulics give you greater tool versatility so you can take on more work with just one machine, and there are several options from which you can choose. A quick coupler circuit, for example, allows you to switch from one tool to another in a matter of minutes – all from the comfort and convenience of the cab.

Powerful and fuel efficient to meet your expectations

Proven Technology

Every U.S. EPA Tier 4 Final, EU Stage IV and Korea Tier 4 ACERT engine is equipped with a combination of proven electronic, fuel, air, and aftertreatment components. Applying these time-tested technologies lets us meet your high expectations for productivity, fuel efficiency, reliability, and service life. Following are the results you can expect:

  • High performance across a variety of applications.
  • Enhanced reliability through commonality and simplicity of design.
  • Maximized uptime and reduced cost with world-class Cat dealer support.
  • Minimized impact of emission systems – with no operator interaction required.
  • Durability with long service life.
  • Improved fuel efficiency with minimized maintenance costs.
  • Same great power and response.

An Emissions Solution That Works

The Cat C15 ACERT engine meets today’s U.S. EPA Tier 4 Final, EU Stage IV and Korea Tier 4 emission standards, and it does so without interrupting your job process. Simply turn the engine on and go to work. It will look for opportunities in your work cycle to regenerate itself, and it will give you plenty of power for the task at hand – all to help keep your owning and operating costs to an absolute minimum.

Fuel Savers That Add Up

The 374F consumes significantly less fuel than the previous series model, and two built-in features help contribute to that: automatic engine speed control and automatic engine idle shutdown. Automatic engine speed control lowers rpm when the machine doesn’t need it for work. Automatic engine idle shutdown turns the engine off when it’s been idling for more than a specified amount of time that you can set through the monitor. You also have a choice of two power modes – high power and economy mode. Simply change between modes through the console switch panel to meet the work needs in front of you. Collectively, all of these benefits add up to reduced fuel consumption, reduced exhaust and sound emissions, reduced repair and maintenance costs, and increased engine life for you.

A Cool Design For Any Temperature

The 374F features a new side-by-side cooling system that allows you to put the machine to work in extremely hot and cold conditions. The system is completely separated from the engine compartment to reduce noise and heat. Plus it features easy-to-clean cores and a new variable-speed fan that reverses to blow out unwanted debris that may accumulate during your work day.

Biodiesel Not A Problem

The Cat C15 ACERT engine can run on up to B20 biodiesel fuel that meets ASTM 6751 standards – all to give you more potential fuel-saving flexibility.

Comfort and convenience to keep you productive all day long

A Safe, Quiet Cab

The all-new 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 as quiet inside as any of today’s top pickup trucks.

Comfortable Seat Options

The seat range includes air suspension, heated, and air cooled options. All seats include a reclining back, upper and lower slide adjustments, and height and tilt angle adjustments to meet your needs for maximum comfort.

A Cool & Warm Environment

The automatic climate control system features multiple air outlets with filtered ventilation to make your work in either hot or cold weather much more pleasant and productive.

Controls Just For You

Not only can the right and left joystick consoles be adjusted to improve your comfort and productivity during the course of a day, but the joystick levers themselves can be adjusted for gain and response. Gain is the relationship between the control lever stroke and cylinder speed, and response is the time elapsed from the moment the control lever is operated until the cylinder attains speed. The 374F has multiple gain and response settings to make the machine respond exactly how you want it to.

A Helpful Monitor

The LCD monitor is easy to see and navigate. Programmable in up to 42 languages to meet the needs of today’s diverse workforce, the monitor clearly displays critical information you need to operate efficiently and effectively. You can even change between the backhoe pattern or excavator control pattern right through the monitor. Plus it projects the image from the standard rearview camera to help you see what’s going on around you so you can stay safely focused on the job at hand.

Ample Storage & Auxiliary Power

Storage spaces are located in the front, rear, and side consoles of the cab. A drink holder accommodates a large mug with handle, and a shelf behind the seat stores large lunch or toolboxes. Two 12-volt power supply sockets are conveniently located near the key storage areas for charging your electronic devices like an MP3 player, a cell phone, or a tablet.

Made to work in your tough, heavy-duty applications

Robust Frames

The 374F is a well-built machine designed to give you a very long service life. The upper frame has mountings made specifically to support the new heavy-duty cab; it’s also reinforced around areas that take on a lot of stress like the boom foot, skirt, and counterweight removal system. Massive bolts are used to attach the track frames to the body, and additional bolts are used to increase the machine’s digging forces, which leads to more productivity for you.

Durable Undercarriage

The 374F’s undercarriage contributes significantly to its outstanding stability and durability. Track shoes, links, rollers, idlers, and final drives are all built with long-lasting, high-tensile-strength steel. Cat Grease Lubricated Track 4 (GLT4) track link protects moving parts by keeping water, debris, and dust out and grease sealed in, which delivers longer wear life and reduced noise when traveling. Cat Positive Pin Retention 2 (PPR2) prevents looseness of the track pin in the track link, reduces stress concentrations, and eliminates pin walking for increased service life. Optional three-piece guide guards help maintain track alignment to improve the machine’s overall performance – whether you’re traveling on a flat, heavy bed of rock or a steep, wet field of mud.

Heavyweight Options

An 11 mt (24,250 lb) counterweight – with or without removal device – is available to balance your work needs. Built with thick steel plates and reinforced fabrications to make it less susceptible to damage, the weight has a curved surface that matches the machine’s sleek, smooth appearance along with an integrated housing to help protect the standard rearview camera.

Options to take on your far-reaching or up-close tasks

Booms & Sticks For Any Job

The 374F is offered with a range of booms and sticks. Each is built with internal baffle plates and is stress relieved for added durability, and each undergoes ultrasound inspection to ensure quality and reliability. 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 boom nose pin retention method is a captured flag design for enhanced durability.

Two Types Available

Two types of booms and sticks are offered: heavy-duty (HD) reach and mass excavation (ME).

The 7.8 m (25'7") HD reach boom and four stick options offer you excellent all-around versatility for general excavation work like multipurpose digging and loading. Following are the four stick length options:

  • The 4.67 m (15'4") stick provides maximum reach and depth in trenching applications.
  • The 4.15 m (13'7") stick is ideal for trenching and general excavating applications.
  • The 3.6 m (11'10") stick delivers greater digging forces and higher bucket capacities than the two longer options while still providing a good working envelope.
  • The 2.84 m (9'4") stick produces the highest digging and lifting forces and largest bucket capacity of the reach sticks; it also provides good stability for hammer applications.

The 7.0 m (23'0") ME boom and the 2.57 m stick offer you enhanced performance in heavy-duty material like rock. They provide higher digging forces due to special boom and stick geometry, and bucket linkage and cylinders are built for greater durability.
