Caterpillar launches new Cat 335F L CR excavator for heavy-duty work in close quarters
Time:2017-8-22   ������:�� �� С��   ���������253

LEICESTER/UNITED KINGDOM, March 16, 2015 - The new compact-radius Caterpillar 335F L CR excavator handles heavy work on congested job sites with minimal risk of property damage, claims Caterpillar. On top, it is said to deliver up to 16 percent improved fuel efficiency and a 5 percent improved lift capacity.

New engine and hydraulics

 

 

 

 

 

 

Caterpillar's recently launched excavator uses electronic, fuel, air, and aftertreatment components, such as a maintenance-free diesel particulate filter, which allow the 335F L CR’s 205-horsepower (151 kW) engine to meet EU Stage IV emission standards. The automatic engine speed control lowers engine rpm during no-load/light-load conditions, the engine idle shutdown system stops the engine after a pre-set idling interval, and the ECO mode allows operators to tailor machine performance to the application. The engine also runs efficiently on biodiesel blends up to B20.

The 335F L CR's hydraulic system places major components in close proximity to minimize piping lengths and to reduce frictional losses and pressure drops. Combined with boom- and stick- regeneration circuits that reduce load on the main pumps, the unique Cat hydraulic system contributes significantly to overall fuel savings.

Compact radius design

When working in small areas, its compact radius design decreases the risk of injuries, damages to buildings and vehicles, or to the machine itself. The 335F L CR is offered with similar digging envelope and bucket sizes as a Cat 30-ton regular (non-compact radius) excavator, i.e. a heavy-duty 6.15 m reach boom and 3.2 m stick provide digging depths to 6.99 m. The new model also increases over-front lifting capacity up to 5 percent, compared with the 328D L CR. An optional blade provides enhanced stability and can also be used to backfill light material.

Operator environment and technology enhancements

Caterpillar claims the pressurized cab is spacious and quiet with large glass areas for all-around visibility. The cab features positive air filtration, height adjustable joystick consoles, a large color monitor, radio with MP3 auxiliary audio port, and available air suspension, heated, and cooled seat options to keep operators comfortable and productive.
Caterpillar allows owners to wirelessly connect to their equipment, providing access to machine data such as location, hours, fuel consumption, idle time, events, and diagnostic codes for analysis and reporting via an online interface. Serviceability features of the new excavator include ground-level access to major maintenance points, electric fuel system priming pump, remote fuel tank drain, and fuel level indicator to avoid overfilling.
