CASE Expands D Series with CX145D SR Minimum-Swing Excavator

New 32,100-pound minimum-swing excavator offers reduced footprint, precision maneuverability and powerful bucket digging force and lift capacity for road and bridge work, utility, landscaping and general construction applications.

CASE Construction Equipment introduces the all-new CX145D SR minimum-swing radius excavator to its D Series lineup. Designed to provide ample digging and lifting power in a small footprint, the CX145D SR features a compact counterweight and modified boom placement. This results in a highly maneuverable and powerful excavator that is easy to transport and ideal for restricted jobsite conditions, such as road and bridge work, utilities, urban construction and landscaping applications.

With an operating weight of 32,100 pounds and a 102 HP Tier 4 Final engine, the CX145D SR offers bucket digging forces up to 21,400 foot-pounds and lift capacities up to 21,350 pounds. Options include a dozer blade configuration as well as the choice between either steel or rubber tracks depending on operating conditions and jobsite requirements.

Each D Series model is built to provide significant operational gains, including faster cycle times, improved responsiveness and greater fuel efficiency. An electronically controlled hydraulic pump and larger control and solenoid valves increase lifting capacities and improve responsiveness.

D Series models offer 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™.

Maintenance-free Tier 4 Solution

The CASE CX145D SR excavator meets Tier 4 Final emissions standards through an innovative combination of selective catalytic reduction (SCR), cooled gas exhaust recirculation (CEGR) and diesel oxidation catalyst (DOC) technologies, which helps maximize uptime and performance – all with minimal maintenance. There is no diesel particulate filter (DPF), no DPF regeneration or associated lifetime service costs.

 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 enhance 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. It actively manages hydraulic power throughout lift/dump and dig/curl movements to maximize speed and efficiency while reducing fuel consumption by minimizing unnecessary hydraulic flow. The operator experiences a more productive machine without losing the precision of the machine’s controls.

An Auto Power Boost feature provides increased breakout forces in tough applications, and overall operation is simplified with three Power Modes to maximize machine performance and fuel economy:

  • Automatic (A): The best balance between productivity and fuel efficiency
  • Heavy Duty (HD): High workload mode
  • Speed Priority (SP): Extra speed and power for the most demanding jobs that require maximum productivity

Greater Feature Standardization

CASE D Series excavators now offer more standard features than any previous CASE crawler 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.

The CX145D SR features an industry-leading operator environment, with a more spacious cab, excellent visibility, a standard fully-adjustable heated air-ride seat, ergonomic multifunctional controls, and a pressurized, viscous-mounted cab that reduces noise and vibration. A standard Bluetooth radio gives operators hands-free functionality that further improves the operator experience. Standard rear-view and side-view cameras feed 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. The optional CASE Max View Monitor provides 270-degree visibility, improving jobsite safety and providing the operator full visibility of the machine’s surroundings.

 New Lighting Package

Each D Series machine is available with a new (optional) LED working light package that provides illumination 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).

New BlastMetriX UAV Improves Blast Design and Analysis by Quickly Capturing Accurate 3D Face Profile Using Unmanned Aerial Vehicles

The new BlastMetriX UAV program from 3GSM GmbH allows quarries and mining operations to take advantage of unmanned aerial vehicle (UAV) technology to quickly, safely an accurately capture three-dimensional face profiles for enhanced visualization of the blast area. The flexible system is the right tool for surveying large blast sites and does not require the use of propriety UAVs. This allows operations to use existing drones in their fleet or locally source drone equipment to take surveying images.

The system requires only the use of aerial targets or the standard BlastMetriX 3D targets as reference points. The low-flying UAV captures multiple data-rich overlapping images to generate hundreds of thousands of data points for accurately characterizing typography of the surveyed area and creating a three-dimensional profile of the face to ensure blast safety and performance.

New users can order a standalone BlastMetriX UAV system that includes all necessary software for UAV surveying and blast design. Alternatively, existing BlastMetriX 3D users only require a simple software upgrade to quickly integrate the usage of UAVs into the surveying capability. It gives operations the flexibility to conduct surveys using either aerial multi-photo images captured by the UAV or terrestrial images from a calibrated digital single-lens reflex (DSLR) camera. This enables surveying operations to continue regardless of no-fly-zone restrictions or inclement weather.

Since BlastMetrix UAV does not rely on Cloud data storage, all surveying and blast design work can be efficiently managed in the field. All captured images are downloaded directly to the computer, allowing BlastMetriX users to efficiently produce a blast design. The designed blast can be georeferenced and data sent directly to smart drills, improving drilling accuracy and driving down costs.

The BlastMetriX UAV system gives technicians the confidence the blast will perform as designed to mitigate flyrock issues, high air overpressures, excessive vibration, poor fragmentation, subpar cast, loss of grade control and wall damage. As a result of blast design optimization using BlastMetriX UAV, operations can realize significant benefits including improved fragmentation, higher crusher throughput and lower drilling manpower requirements.

The new BlastMetriX UAV system gives operations advanced analytical tools for measuring blast performance, so programs can be optimized. BlastMetriX UAV offers pre/post blast comparisons, pre/post excavation reporting, muckpile quanitifcation – movement, volume and swell – and power trough analysis.

The scalable BlastMetriX UAV software allows companies to integrate as much or as little technology as required. Its capabilities can be expanded to meet an operation’s growing needs. Professional service, support and training of program use are provided by RAM, Inc. of Powell, Ohio. Additionally, RAM, Inc. conducts UAV ground schools to teach operators how to fly UAVs, prepare students for taking the FAA 107 pilot’s test and to help operations maximize use of UAV surveying technology.

Products At Work: Hospital Built to Plan

MEP contractor’s technology precisely places plumbing / HVAC systems

By Jeff Winke

The Denver, Colorado suburb of Northglenn sold 5.7 acres of vacant land to SCL Health Community Hospitals for the construction of a 60,000-square-foot community-based hospital and medical office facility. The location is less than a half mile from I-25.

            The Northglenn SCL Health Community Hospital follows the new healthcare model, which favors smaller, more accessible hospitals located within neighborhoods. Yet, the three-story new hospital will provide many of the same services found in larger traditional hospitals, such as an emergency room, inpatient beds, and laboratory and imaging services.

            AMI Mechanical Inc., based in Thornton, Colorado, is responsible for the fabrication and installation of all the mechanical systems in this small building with its 218 foot by 88-foot structure footprint. All the systems were fabricated in house in a clean, controlled environment, which made for a cleaner, safer worksite. This was an approximate $5 million project.

            Since 1991, AMI Mechanical has established itself in the Rocky Mountain Region and handles projects ranging in size from $200,000 to $25 Million, with a yearly volume of $70 Million. In addition to their management, engineering and administrative staff, AMI Mechanical employs more than 275 skilled and experienced field trades workers. A crew of 20 or so worked on the SCL Hospital’s plumbing and waste piping system and eight to 10 were assigned to the project’s HVAC duct installation crew.

            “The structure is tilt-up construction so once the concrete side forms were tied in place and we received the green light to go, things moved fast,” states Sean Lauck, BIM manager for AMI Mechanical. “We had plenty to do on our end but we needed to coordinate with the various other contractors to make sure the interior construction went smoothly.”

            Hospitals require a lot of water, power, and proper air circulation for exam rooms and operating theaters, as well as X-ray facilities. It can be a more complicated build than a hotel or apartment building with similar number of rooms because of the critical need for environmental control and the sophisticated technology that can be used in the rooms.

            “We’re dealing with a four to 4½ foot ceiling cavity that can be packed with cables, piping, lighting fixture housing, air circulation systems, and structural I-beams, so we need to know where everything goes precisely,” Lauck said. “There was no room for missteps or errors.”

            Until the roof was built and enclosed the building, weather also became a challenge. There were bitter cold days and snowstorms. The snow and ice delayed AMI Mechanical until the decks were cleared.

            AMI Mechanical created a digital model, which represents the physical, technical, and functional characteristics of the Northglenn SCL Health Community Hospital building. The model included 3D coordinates and vector information that represent the geometry of the building and its components.

            The 3D digital model also details the entire network of piping and ductwork to be installed, as well as the structural elements, HVAC hanger anchor inserts, and penetration points on each deck where piping must travel through. 



“For each of the three decks, we’re placing 3,000 to 4,000 hangers alone, which translates to a large amount of data,” Lauck stated. “And each hanger needs to be anchored at its correct point, which is where our total station and layout navigator instruments play critical roles.”

            Lauck worked with GeoShack in Commerce City, Colorado to select the best technology for the project. GeoShack is an authorized Sokkia and Topcon dealer, which are products that Lauck has worked with for years, knows best, and prefers. GeoShack helped in selecting the best technology for the Northglenn SCL Health facility project and provided start-up assistance, training, and on-call troubleshooting help.

            Through GeoShack, AMI Mechanical acquired a Topcon PS-103 robotic total station, which is positioned as the most advanced robotic total station available. Because it’s designed to offer precision positioning capability, AMI Mechanical used the PS Series total station with  to ensure accurate placement of piping and ductwork hangers.

            Also acquired was a Topcon LN-100 Layout Navigator using MAGNET Layout software, which is considered the first 3D positioning system designed specifically for construction layout.  The LN-100 uses laser and robotic total station technologies to create a totally new tool. The challenge the LN-100 addresses is the construction coordination, which was essential for the Northglenn site.

           Lauck appreciated that the LN-100 could be mounted on a structural column so that there is less floor vibration than a floor tripod, which is susceptible to the jars and vibrations of materials being loaded on the floor for use,

            “Knowing what work has been completed during the project and working from the same design plan throughout is critical to maintain schedule and avoid costly collisions on this hospital project,” said Lauck. “The LN-100 helped us stay connected to the same design and focused on each critical step in the process.”

            Lauck also likes the fact that he can pair up the robotic total station and layout navigator with any brand of data collector. The Topcon instruments are not restricted to their own brand of data collectors, which provides the contractor with flexibility should there ever be a need and the only option is a competitive brand data collector.

            “Being able to access and apply the BIM 3D model through our robot and LN-100 made it possible to deliver the quality results we had planned,” Lauck stated. “Since we needed to coordinate our efforts with other contractors on the site, the technology allowed us to work faster and better—essentially accelerate our work flow when necessary to fit the needs of the other contractors.”
The Northglenn SCL Health Community Hospital facility was completed on schedule.

            “This will be fun to visit the Northglenn hospital sometime in the future just to see it fully functioning,” said Lauck. “I’ll feel good knowing we’ve done a good job and everything in the building’s mechanicals is in place… exactly where it needs to be.”
