New Cat® 336F L/LN Excavator Delivers Superior Productivity and Fuel Efficiency with Reduced Emissions

For Release in Europe: March 2015
Release Number: 39PR15

The new Cat® 336F L/LN excavator, replacing the 336E L/LN, has both a C9.3 ACERT engine that meets EU Stage IV emissions standards and a number of new features that enhance overall fuel efficiency and deliver fuel savings of up to 8 percent, compared with its predecessor. A powerful hydraulic system easily handles a range of buckets and work tools for efficient performance on any job site, and a large, well-appointed cab ensures operator comfort and convenience for sustained high production.

Powerful Stage IV engine

Rated at 321 metric horsepower (236 kW) and designed to operate efficiently on bio-diesel blends to B20, the fuel-efficient C9.3 ACERT engine uses a diesel particulate filter regeneration system that does not interrupt work cycles or require operator intervention. For further fuel savings, the operator can reduce engine speed to idle with the touch of a button, an automatic engine-idle-shutdown feature stops the engine after a pre-set idling interval, and an economy power mode adjusts the engine for optimum fuel efficiency.

Efficient Hydraulic Systems

The 336F L/LN's Electronic Standardized Programmable pump saves significant fuel by matching engine performance to the load encountered.

Ample hydraulic flow in the 336F L/LN's implement circuits and a high main relief pressure generate the power to handle a range of buckets and work tools, including shears, multi-processors, hydraulic breakers, and rippers. Overall hydraulic efficiency is enhanced via electric boom and stick regeneration valves that recycle hydraulic fluid and further reduce pump loads.

Operator environment

The roll-over-protective-structure (ROPS) cab is spacious and quiet with large glass areas for all-around visibility. Positive air filtration pressurizes the cabin to keep out dust, and height-adjustable joystick consoles, large color monitor, and available air-suspension/heated/ cooled seat ensure operator comfort and productivity. For enhanced safety, standard equipment includes time-delay working lights and a rearview camera.

Durable structures

Undercarriage choices for the new model include the heavy-duty long (L) and long/narrow (LN) configurations. Massive frames and counterweight combine to form an exceptionally strong, stable work platform for digging, lifting, and attachment use.

The heavy-duty (HD), 6.5-m reach boom and three stick options—3.9 m (available only with the long undercarriage), 3.2 m and 2.8 m—provide excellent all-around versatility for general excavation work, such as multipurpose digging and loading. The 6.18 m mass-excavation (ME) boom and matching 2.55 m stick are designed for enhanced performance and production when moving high volumes of heavy material.

Technology enhancements

In order to realize maximum return on investment, equipment owners must employ machines to full potential—producing more in less time, using less fuel, avoiding unnecessary machine wear, and ensuring safety on the job site. Cat Connect assists customers in attaining these goals by capitalizing on Caterpillar technology and Cat dealer services.

Cat Grade Control Depth and Slope, a factory-integrated system standard for the new 336F models, uses protected sensors in the front linkage to provide real-time positioning and cut/fill data through the cab monitor. Operators save time by attaining specifications on the first pass, while conserving fuel, reducing machine wear, conserving fill materials, and minimizing grade-checker involvement. Cat dealers can easily upgrade the system to 3D capability with Cat AccuGrade™ GPS or Universal Total Station (UTS) packages. 

LINK technologies, such as the Product Link™ system, wirelessly connect owners to their machines, providing access to data—such as location, hours, fuel consumption, idle time, events, and diagnostic codes—for analysis and reporting via the online VisionLink® user interface. LINK information allows fact-based decision making and increased efficiency.

Serviceability and safety

Ground-level access to most major maintenance points, an electric fuel-priming pump, remote fuel-tank drain, and a fuel-level indicator (to avoid overfilling) simplify routine service, and machine features such as the cab-integrated ROPS, anti-skid surfaces, programmable halogen working lights, large skylight, and a standard rearview camera system enhance safety.
