Cat’s 336E 18% more powerful

The 336E, which replaces the 336D, features a more-powerful engine for increased digging and lifting performance, an enhanced operator environment, serviceability improvements and new styling. With more than 9000 test hours to its credit, the 336E is designed to deliver exceptional productivity, reliability and uptime. Coupled with the strength of the worldwide Cat dealer network, the 336E provides uncommon value for the customer, Caterpillar claims.
In addition to meeting Stage IIIB/Tier 4 Interim emissions requirements, the 336E also meets all applicable sound-level and safety regulations, including the ISO (International Standards Organization) requirements for visibility. The 336E is fitted with new mirrors and has provision for an integrated rear-view camera.
Productivity gains
With a net power rating of 236 kW (317 hp), the 336E's Cat C9 engine delivers 18 percent more power than does its 336D predecessor. The C9 engine features advanced electronic control, precise fuel delivery and refined air management for optimum performance and reduced fuel consumption. Increased power results in faster digging and loading cycles for added production, while the overall design of the new 336E assures outstanding fuel-efficiency (material moved per gallon/liter of fuel).
Increased hydraulic pressure in the 336E's heavy-lift system, coupled with features that promote greater machine stability, yields increased lifting capacity—allowing the 336E to work more productively in pipe-handling operations.
To accommodate the 336E's increased lifting capacity, the boom, digging arm and boom-foot mount have been strengthened to assure durability. The swing frame also has been strengthened to support the machine's redesigned ROPS (Roll Over Protection Structure).
Boom and digging-arm options allow the 336E to be configured for optimum performance in a range of applications, including those involving mass excavation and hydraulic-breaker operation. A new hydraulic main-control valve and an integrated electric regeneration valve in the boom circuit (for capturing and recycling unused energy) also contribute to significant fuel savings. In addition, the new machine is Cat AccuGrade™ Ready, facilitating installation of 2D and 3D grade-control systems for increased productivity and further fuel savings.

Operator amenities and serviceability
A new monitor in the cab is 40 percent larger and provides significantly enhanced resolution.  The monitor, which features quick-access buttons that complement a new screen layout, also can display up to three rear-view-camera images.

For the operator's further convenience, height of the joystick consoles is now adjustable, and the seat cushion is wider. An optional air-cooled seat improves operator comfort in warm weather, and a new air-conditioner compressor improves cab cooling. The 336E's cab is quieter, reducing operator fatigue and allowing the operator to work more productively. A new radio has an auxiliary input for devices such as MP3 players.

To simplify routine maintenance, the 336E uses a side-by-side cooling package (radiator/oil cooler/charge-air cooler) that eliminates previously stacked cooling modules. The new cooling package is readily accessible via the 336E's one-piece engine hood and is easy to clean. Also, optional remote engine-oil and hydraulic-oil drains facilitate environmentally friendly service, and the 336E's redesigned air-conditioning system is easier to maintain. For greater safety,
time-delay working lights remain on longer for entering and exiting the cab at night.
Complementing the overall design of the 336E are styling changes, including new sheet metal, new paint scheme for the cab, Cat logo recessed into the counterweight and model designations repositioned to panels just behind the cab. New sheet metal includes a new, layered-construction door that is lighter in weight but exceptionally durable.
