Built to demolish tall structures, the new Cat 340 UHD ultra high demolition excavator has a pin height more than one percent higher than the 340F UHD, allowing it to reach up to eight floors. More UHD and retrofit boom/stick configurations, along with a range of Cat demolition attachments, deliver increased machine flexibility to meet contractors' job site needs to maximize machine utilization. Its coupling system allows for switching between two UHD fronts and retrofit booms and sticks with no special tools in 15 minutes.

Design updates have simplified transporting the 340 UHD excavator. The hydraulically actuated variable-gauge undercarriage is built to deliver both stability and efficient transport by offering a 13'4" (4000 mm) extended width that retracts to only 9'10" (3000 mm) with 24" (600 mm) track shoes for transport. A one-piece cradle design, compared to two-piece on the 340F UHD, reduces UHD boom transportation height to less than 9'10" (3000 mm).

Flexible efficiency

The new 340 UHD allows for the sticks to be configured with Cat couplers to maximize machine versatility and productivity. With two UHD front options available, the 72'2" (22-m) front offers a maximum 8,160 lb. (3.7-ton) weight at stick pin and maximum horizontal reach of 44'5" (13.55 m) at stick nose over the front and side of the machine. Working with a 7,280 lb. (3.3-ton) maximum weight at stick pin, the 82' (25-m) front offers a 43'9" (13.33-m) maximum reach at stick nose over the front and side of the machine. It matches the line of Cat multi-processors, specifically the MP332 and MP324.

The hydraulic boom lines are quickly connected and disconnected by hand without the use of special tools. Contractors can choose between one- or two-piece boom options for high-productivity truck loading or low-level demolition work. Three stick options are available at lengths of 9'2" (2.8), 10'6" (3.2 m) and 12'10" (3.9 m) and Standard Cat Payload provides on-the-go weighing and real-time estimates of the payload so operators can achieve precise load targets when working with the one piece retrofit boom.

Rated at 311 hp (232 kW), the U.S. EPA Tier 4 Final Cat C9.3B engine powering the new 340 UHD excavator runs on either diesel or biodiesel fuel up to B20 to meet job site requirements. Three engine power modes - power, smart and eco - match the machine to job needs, reducing fuel consumption over the 340F UHD. Smart mode automatically matches engine and hydraulic power requirements, providing maximum power output when needed and reducing power on less demanding tasks to save fuel. A new hydraulic reversing fan cools the engine on demand to help reduce fuel consumption.

The 340 UHD features a 30-degree tilt-up cab design for more productive demolition and a comfortable sight line without neck strain when working on eight-floor buildings.

Operator productivity and safety

Operators navigate machine configuration and operating parameters on the 10" (254-mm) touchscreen monitor. Viewed through the new monitor, the Cat active stability monitoring system informs operators if the work tool is positioned within the safe working range and provides audible and visual warning alerts when approaching the stability limit. Ranging from 1.5 to 10 percent, the stability ratio side bar changes length and color from green to yellow to red, depending on the ratio.

The machine's new left-hand tilt-up console helps to improve ingress/egress up to 4 percent. Operators can program machine operating settings, including the joystick button controls, and the system stores each setting, based on the operator ID.

The 340 UHD features a 30-degree tilt-up cab design for more productive demolition and a comfortable sight line without neck strain when working on eight-floor buildings.  The demolition cab is equipped with Falling Object Guard Structure (FOGS), and front and roof P5A, 0.4" (10-mm) laminated glass for safety. The windshield and roof glass feature one-piece parallel wipers with three intermittent settings with washer spray. Standard rearview and side view cameras provide visibility of the operating area on the in-cab monitor.

Lowered maintenance costs

Maintenance intervals are extended and more synchronized on the Cat 340 UHD excavator to lower operating costs and reduce service time. Offering a 5 percent longer service life, the new hydraulic filter improves filtration and features a 3,000-hour change interval while anti-drain valves keep the oil clean during filter replacement. The engine air intake filter with pre-cleaner delivers double the dust holding capacity of the previous design. Grouped on the right-hand side of the machine, all fuel filters change at a synchronized 1,000-hour interval. Operators can track filter life and maintenance intervals on the new in-cab monitor.

A ground-level shutoff switch stops all fuel to the engine and shuts down the machine, improving safety while servicing. The machine's new flat engine hood improves rear visibility and incorporates a wide-opening design for simplified servicing and oil level checking. All other daily maintenance routine checkpoints are accessible from ground level as is the location for draining fuel system water and fuel tank water to help save time.

Technology increases management efficiency

Beyond Cat Payload, the new 340 UHD with the single retrofit boom is equipped with a host of Cat technologies designed to drive productivity and service efficiency. Cat E-fence and Cat Grade with 2D guides depth, slope and horizontal distance to grade through the touchscreen monitor to boost machine productivity. The machine automatically compensates for excavator pitch and roll caused by sloping ground conditions through use of GPS and GLONASS systems.

Standard Cat Product Link captures critical machine operating data and condition and reports this data to field managers and the office via VisionLink. Remote Troubleshoot analyzes real-time machine data captured by Product Link for diagnostics without impacting machine productivity and saving a service trip to the job site.

Why invest money in an intelligent MRF (4.0)?

Traditionally, waste management companies have operated using a simple "management of waste" approach to operating a MRF. Throughput targets and continuous operation (minimal downtime) were the main driving forces. The industry has changed however, and the focus moving forward is now on optimizing system performance and reliability, in conjunction with increasing recycling rates and a drive for a "greener" and more sustainable tomorrow.

When considering the addition of, or upgrade to, an "intelligent" MRF, for municipalities or private operators, the main factors should always be the client's (operator) current requirements, and evolving market needs, which include throughput, reliability, output quality, and adaptability. Equally important is a full understanding of what is really expected from any proposed system. Having an engaged and focused mindset for the project with the client from the beginning, will impact and drive the entire design process. This then impacts the overall project result, through to the productive, efficient, ongoing operation of the facility itself.
