Integrated design for Cat® 340F and 352F Long Reach Excavators provides ample digging and lifting capability at extended distances17.09.2015 15.00
The new Cat® 340F Long Reach and 352F Long Reach Excavators are specifically designed for applications that require exceptionally deep digging or excavating at extended distances, such as working in sand and gravel pits, shaping long slopes, and cleaning settling ponds. The new models are equally capable of digging and lifting applications, with large buckets and heavy-duty high/wide undercarriages that provide added stability over the side. These special-application machines are designed by Caterpillar engineers and manufactured in Caterpillar factories, resulting in an integrated design that ensures the optimum reliability, performance, and serviceability that customers have long experienced with Cat D models. The 340F Long Reach excavator will be available in third quarter 2015 while the 352F Long Reach excavator will be available in first quarter 2016. The 340F Long Reach features a Cat C9.3 ACERT™ engine and the 352F Long Reach Excavator features a C13 ACERT engine, both meeting EU Stage IV emission standards. The excavators also incorporate a special heavy-duty upper frame, swing bearing and carbody—the massive structure that joins the swinging upper frame to the track frames. These heavy-duty members combine with added counterweight to provide maximum-reach dimensions at ground level of 18 080 mm for the 340F and 19 640 mm for the 352F. Maximum digging depths are 13 050 mm and 13 040 mm, respectively. Hydraulic capability Implement hydraulic systems for the 340F Long Reach and 352F Long Reach Excavators have ample hydraulic flow at high pressures to accommodate the special demands placed on these machines, delivering power and maximum control for a range of excavating buckets and hydraulic work tools. For overall system efficiency, major hydraulic components are located in close proximity—allowing shorter connecting tubes and hoses that reduce frictional losses and pressure reductions. The result is reduced loading on the system for added fuel savings. The main control valve also is designed to respond proportionally to control-lever movement for precise controllability of hydraulic functions. Operator’s station Cabs for the 340F Long Reach and 352F Long Reach Excavators are spacious and comfortable, featuring an automatic climate-control system that maintains consistent temperatures. Low-effort joystick controllers are mounted in height-adjustable consoles that complement adjustable armrests and a fully adjustable, high-back seat. The cab’s large glass areas enhance visibility, and special sealing and insulation help keep the operator's environment clean and quiet. The large, high-resolution, LCD monitor is designed for easy navigation and provides critical operating information. Serviceability/technology Routine maintenance points are easily accessed from ground level, including greasing points, fluid taps, filters, and drain tubes. Service-compartment doors are designed to prevent debris entry and latch securely in the open position for machine maintenance. The side-by-side cooling system is designed for optimum efficiency and easy cleaning. LINK technologies, such as the Product Link™ system, allow fleet owners to increase productivity and lower operating costs by tracking critical items, such as machine location, hours, fuel usage, diagnostic codes, and idle time via the online VisionLink® interface. |
