Tom Ewing’s Environmental Update

* The US House is busy again this week on energy and environment issues with the Select Subcommittee on Chatter holding a hearing entitled, “Midterm Review and Update on the Corporate Average Fuel Economy Program and Greenhouse Gas Emissions Standards for Motor Vehicles,” Thursday, September 22, at 10 a.m. in HVC-210 of the Capitol Visitor Center. The hearing will examine the Corporate Average Fuel Economy (CAFE) program and greenhouse gas (GHG) standards set by the National Highway Traffic Safety Administration (NHTSA) and Environmental Protection Agency (EPA).

* If you are a cow, you might be feeling a little beat up on lately, considering all of this messy methane business and global warming. Like it’s your fault, right, that Americans love milk and cream cheese and ice cream and hamburgers (make mine a cheeseburger). The US Dairy Production Stabilization Act of 1983 authorizes a national program for dairy product promotion, research and nutrition education. Is that in the same contradictory policy-class as tax breaks and subsidies to help expand petroleum and coal operations? Cow, uh, vapors and manure are significant sources of methane, a compound far worse than CO2 for trapping heat. USDA reported last week that in 2014, total milk production was 206,586 million pounds. California and Hawaii: 42,366.9 million pounds. I can’t comprehend those numbers, but how do you get this to change in a world with hungry people?

* A trillion tons. That’s the atmospheric limit for CO2 (and equivalent) concentrations. Since 1750 humans have added 600 billion tons. Beyond a trillion? Don’t think about it. And don’t get complacent about ratcheting way back to stop the next 400 billion. In fact, it can’t happen without CCS – carbon sequestration and capture. These are some of the lessons in an excellent webinar – “A Better Life with a Healthy Planet: Pathways to Net-Zero Emissions” – available from the CCS Institute, presented by David Hone, Chief Climate Change Adviser for Shell and a board member and former Chair of the International Emissions Trading Association (IETA). Mr. Hone’s presentation is engaging, analytical, big-picture and jargon free. Watch it.

Have a great Monday and a great week!

CASE Long Reach Excavators Add Increased Digging Capabilities to D Series Lineup

Two D Series excavators – the CX210D LR and CX250D LR – offer increased dig radius and depth with Long Reach (LR) models.

case_cx210d_lr_2CASE Construction Equipment’s CX210D LR and CX250D LR crawler excavators provide increased operating performance for deep trenching, sloping, demolition, dredging, digging in sand or gravel pits or any application that requires long-distance bucket reach and precision. Each Long Reach (LR) model features an elongated boom and arm for increased digging capabilities in deep or long-distance digging applications, while providing the same improved responsiveness and multifunction controls of the D Series.

Each model also offers more standard features than previous CASE excavators, simplifying the buying process and making them extremely versatile and operator friendly. All CASE D Series excavators provide peace of mind and lower total cost of ownership through CASE ProCare™.

Basic Operating Specs:

CX210D LR:

160 horsepower

Operating weight 51,900 pounds

Max dig radius: 51 feet 2 inches

Max dig depth: 39 feet 4 inches

Bucket digging force: 14,600 foot pounds

CX250D LR:

177 horsepower

Operating weight 63,523 pounds

Max dig radius: 60 feet 1 inch

Max dig depth: 47 feet 9 inches

Bucket digging force: 17,310 foot pounds

The CX210D LR and CX250D LR both employ an SCR Tier 4 Final solution that provides greater fuel efficiency (CX210D LR – up to 9%, CX250D LR – up to 14%) without sacrificing power. SCR lets the engine run at peak performance throughout the work cycle and, because it works without a diesel particulate filter (DPF), there’s no DPF regeneration or associated lifetime service costs. This helps maximize uptime and performance – all with minimal maintenance.

case_cx210d_lr Intelligent Speed, Power and Efficiency

Faster cycle times are achieved through a new electronically controlled pump, a larger control valve and multiple sensors. These features combine with the CASE Intelligent Hydraulic System and its four integrated control systems to make the best use of the machine’s hydraulic power and momentum, resulting in added strength and fuel efficiency.

The four systems that make up the CASE Intelligent Hydraulic System are: Boom Economy Control (BEC), which reduces RPMs by using gravity during boom down and swing; Auto Economy Control (AEC), which lowers RPMs during idle and automatically shuts down the engine after a preset idle time; Swing Relief Control (SWC), which reduces hydraulic power at the swing start; and Spool Stroke Control (SSC), which adjusts hydraulic pressure during digs.

Using improvements to the Spool Stroke Control system, the CX210D LR and CX250D LR excavators re-use hydraulic fluid whenever possible to automatically increase cycle times and efficiency. The operator experiences a more productive machine without losing the precision of the machine’s controls.

The CX210D LR and CX250D LR excavators also provide the operator with three working modes – Speed Priority, Heavy and Automatic – that help the machine conserve energy and exert only as much power as needed to complete the job at hand.

More Robust Design

The arm and boom of each D Series excavator have been built stronger for greater durability and to support the added power of the machine. The undercarriage is built with thicker steel and a new single-slope design that reduces dirt accumulation and eases cleaning.

Greater Feature Standardization

CASE D Series excavators now offer more standard features than any previous CASE excavator. This includes Free Swing for improved craning, laying or lifting of offset loads; oil sample ports for quick sampling of engine and hydraulic oils; and an easy pattern selector for the operator’s preference of ISO or SAE controls. Each D Series excavator features a fully adjustable operator station anchored by a standard heated air-ride seat and joystick controls that allow for smooth performance.

These excavators also feature best-in-class cab space, excellent visibility, and a pressurized and iso-mounted cab that keeps noise and vibration down. A standard Bluetooth radio gives operators hands-free functionality that further improves the operator experience. A standard rearview camera feeds a 7-inch widescreen monitor that also provides operators with real-time access to important performance parameters, including fuel consumption, operating hours and machine information.

Light it Up

Each machine is available with a new (optional) LED working light package that provides illumination similar to sunlight – and more than three-times brighter than halogen – allowing contractors to work around the clock. The LED package includes six LED lights (two front, two rear and one on each side) and a side-view camera.

CASE ProCare

All CASE D Series excavators are covered under CASE ProCare – a suite of product assurances that includes a three-year Advanced CASE SiteWatch™ telematics subscription, a three-year/3,000-hour full-machine factory warranty, and a three-year/3,000-hour planned maintenance contract. ProCare allows business owners to invest in new equipment while helping to make owning and operating costs predictable for the first three years of lease or ownership.

New Cat® Tilt Buckets Handle Angled -Surface And Precision- Grading Tasks

cm20160913-10121-30136A new line of Cat® tilt buckets is available for Cat crawler-excavator models 311-325 and for wheel excavator models M314–M322. The new buckets, available in both pin-on and coupler configurations, hydraulically tilt 45 degrees from vertical, right and left, to provide added capability when working on angled surfaces or performing precise grading. The buckets install easily and are designed for such applications as ditch cleaning, landscaping, and various construction tasks. In addition, the buckets can be used for conventional excavating in low-impact soils, including topsoil and clay.

The tilt buckets are equipped with two horizontal cylinders—sized to provide forces matched to the machine—that allow the operator to position the bucket and maintain grade without moving the machine. The horizontal-cylinder design allows a low profile for the bucket, while protecting the cylinders from material flow.

Grade-control ready

The new buckets are drilled and tapped to accept the bolt-on sensor and clips required to make them “plug-and-play” compatible with Cat Grade Control 3D. Grade control provides visual and audio positioning guidance for the operator via the machine’s in-cab monitor, enhancing the speed, accuracy, and material-movement efficiency of excavating and grading tasks.

Bucket protection

Tilt buckets feature a reversible, wear-resistant, bolt-on cutting edge that protects the base edge and provides extended service life. In addition, bucket surfaces subject to heavy wear, such as corners, are protected with replaceable, weld-in inserts of premium-grade steel (400 BHN).
