The New 336E Hydraulic Excavator
GROUND REPORT
New Caterpillar 336E Hydraulic Excavator
Enhances Productivity, Reliability and Durability
T
he new CatŪ 336E hydraulic excavator is among the first CaterpillarŪ machines to meet European Stage IIIB and Environmental Protection Agency Tier 4 Interim emissions standards. 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. The 336E also meets all applicable sound-level and safety regulations, including the ISO (International Standards Organization) requirements for visibility. The 336E has a provision for an integrated rear-view camera.
The boom, digging arm and boomfoot mount have been strengthened to assure durability, and the swing frame has been strengthened to support the machine's redesigned Roll-Over Protection Structure. Boom and digging-arm options allow the 336E to be configured for optimum performance in a range of applications. 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. The 336E is Cat AccuGradeTM ready, facilitating installation of 2D and 3D grade-control systems for increased productivity and further fuel savings.
Productivity gains With a net power rating of 317 hp (236 kW), the 336E's Cat C9 engine delivers 18 percent more power than does its 336D predecessor. The C9 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 336E assures outstanding fuel efficiency. 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 pipehandling operations.
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-viewcamera images.
