Vacuworx Vacuum Lifting Technology Lands on White House Steps

Vacuum Lifting Technology Lands on White House Steps

National Park Service cites safety and versatility among major considerations when deciding on concrete lifting system manufactured by Tulsa-based Vacuworx to handle recent renovation of South Portico stairways at the White House.

Vacuum lifting technology has made its way to the White House as part of the National Park Service’s historic renovation of the building’s South Portico steps. The $1 million project, which included dismantling Truman-era staircases and installing carefully selected cuts of Missouri limestone, was completed between August 5 and August 30, 2017.

Jessica Gordon, an exhibits specialist with NPS’ Historic Preservation Training Center (HPTC), said a material handling solution that incorporated a Vacuworx MC Series Vacuum Lifting System proved advantageous as crews pulled two base stones weighing approximately 2,400 lb. each, and set a total of 46 new slabs. Each new South Portico step – there are 21 located on the east and 21 on the west – are approximately 10 in. long, 7 in. deep and 20 in. wide. The four new landing stones are 11 ft. long, 7 in. thick and 6 ft. wide. Gordon worked directly with Vacuworx to rent an MC 5 lifter and three custom pad assemblies. The carrier equipment was rented from Extreme Steel & Rigging, based in Warrenton, Virginia.

The MC 5 operates using a self-contained diesel engine. When activated, the system pulls a vacuum between the pad and object to be lifted, providing a powerful positive seal. Eliminating the need for straps, Gordon noted, saved crews nearly 8 hours as she estimates that method would have required an additional 10 minutes per limestone step during the installation process. The application of vacuum lifting also mitigated the risk of chipping the top-grade material by prying on it with a bucket or fork, she said and curbed the possibility of damaging an adjacent patio on the South Lawn.

“We’re moving, fitting, lifting, spreading the mud and laying it down,” Gordon said. “All the re-handling; it adds up. With the remote operation, we can safely pick up and maneuver materials

without compressors, hoses or other accessories presenting trip hazards. What really sold us is that everything is self-contained, in one unit.”

The timing of the South Portico project overlapped a remodel of 1600 Pennsylvania Avenue that was facilitated by NPS and the General Services Administration. The $3.4 million project was completed in August and included the replacement a 27-year-old HVAC system along with renovations of the Navy Mess kitchen, West Wing lower lobby, and IT system. According to the White House, these renovation plans had been approved by the previous administration.

The NPS’ Frederick, Maryland-based Historic Preservation Training Center focuses on maintaining and preserving icons of historical and cultural significance throughout the United States. Gordon said that the agency handles about 35 to 40 projects a year, among its three divisions: Masonry, Woodcrafting and Carpentry. The scope of its masonry work includes 10 to 15 jobs a year, she said, with the typical project cost ranging between an estimated $50,000 and $400,000. According to Gordon, “Our work is project-based, so the rental option works well for us. Versatility is a major consideration.” Vacuworx Vacuum Lifting Systems were also used by NPS to help rehabilitate the steps that guide visitors to a memorial building at Abraham Lincoln Birthplace National Historical Park in Hodgenville, Kentucky.

were erected in 1952, during the presidency of Harry S. Truman. Springfield-based Phenix Marble Co. quarried the newly installed limestone. “The NPS has been handling maintenance projects at the White House since 2001,” Gordon said. “It’s enjoyable to be part of making history.”

AEM Poll: Rural-Urban Agreement on Need for Infrastructure Investment

An overwhelming majority of Americans in urban, suburban and rural communities believe that investing in infrastructure will improve the U.S. economy according to a new poll released Tuesday by the Association of Equipment Manufacturers(AEM).

While infrastructure needs differ in different parts of the country, the new survey shows that adults strongly support modernizing U.S. infrastructure and believe that investments will create jobs and improve their quality of life.

“The findings underscore the fact that infrastructure connects rural and urban America – both literally and physically,” said AEM president Dennis Slater. “America’s infrastructure was once the envy of the world, but after years of underinvestment, our infrastructure and connectivity between rural and urban America have deteriorated considerably. This is one of the areas rural and urban Americans agree on today – that we must modernize and rebuild our infrastructure to reclaim the infrastructure advantage we once had.”

The national poll identified a number of key findings, including

  • An overwhelming majority (89 percent) of all adults believe that investments in infrastructure will strengthen the U.S. economy, including eighty-six (86) percent of urban and eighty-nine (89) percent of rural Americans.
  • More than eight out of every ten adults (82 percent) agree that investments in infrastructure will increase the number of jobs in their communities, with eighty-four (84) percent of suburban, eighty-two (82) percent of urban and eighty (80) percent of rural Americans sharing this belief.
  • Americans across the country agree that investments in infrastructure will improve their quality of life (81 percent). This sentiment is equally strong in suburbs or towns (82 percent), cities (80 percent) and rural America (79 percent).

“It is time for Congress and the administration to listen to the American people and rebuild our infrastructure, spur economic growth and accelerate job creation as a result,” said Kip Eideberg, AEM vice president of public affairs and advocacy.

Respondents also identified transportation, construction and manufacturing as the top industries poised to benefit most from increased infrastructure investment. Thirty (30) percent of all Americans pointed to manufacturing as one of the three primary beneficiaries of increased spending on infrastructure, a figure that rises among Midwesterners (34 percent) and rural Americans (34 percent).

The poll also found that a third of Americans (33 percent) believe that investing in broadband and wireless connectivity would most likely benefit their ability to access educational and workforce training resources.

The findings support recommendations made in a recently released report by AEM called The U.S. Infrastructure Advantage (TM). The report emphasizes the importance of the United States reclaiming its infrastructure advantage in order to maintain its global economic dominance. The report also highlights several areas in which infrastructure, such as surface transportation and broadband, provide critical links between urban and rural communities and economies.

About the Survey

AEM conducted the poll in partnership with YouGov through its online omnibus survey. The survey was fielded to 3,481 U.S. adults, including 667 adults who self-identify as living in a rural area. Figures have been weighted and are representative of all American adults (18+). Fieldwork was conducted between July 26 and July 28, 2017.

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).
