Cat’s latest excavator launch is the Stage IV compliant 36.2 to 38.9 tonne 336F tracked excavator that replaces the previous ‘E’ series version. Power comes from a 236 kW (317 hp) C9.3 diesel that uses a diesel particulate filter regeneration system that the company says does not interrupt work cycles or require operation. According to Cat, a number of new features enhance overall fuel efficiency and deliver full savings of up to 8% compared to the 336E.
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 (21.4 ft) reach boom and three stick options - 3.9 m (12.8 ft) available only with the long undercarriage, 3.2 m (10.5 ft) and 2.8 m (9.2 ft) - provide excellent all-around versatility for general excavation work, such as multipurpose digging and loading. The 6.2 m (20.4 ft) mass excavation (ME) boom and matching 2.6 m (8.5 ft) stick are designed for enhanced performance and production when moving high volumes of heavy material.
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.
