CRITICAL BACKUP GENERATORS HAULED BY BARNHART

Barnhart crews from the Memphis branch recently transported two 310,00 natural gas-fired generators to a substation in Tallahassee. The substation serves critical customers including Tallahassee Memorial HealthCare and the Tallahassee Police Department, and the move was part of continued efforts to enhance electric reliability.

The generators arrived by rail and, due to their size, were moved one at a time. Barnhart used a GS-800 transporter, which was over 300 feet long with 12 axles. Since the load had to be moved through normally busy downtown Tallahassee and the college district, the generators were moved overnight to minimize traffic impact. Crews accompanied the transport to raise utility lines and trim tree limbs along the delivery route. One reason the GS-800 was chosen for the job was because its low clearance enabled the transporter to get around live oak trees, which could not be trimmed.

The first haul took 12 hours to complete as crews became familiar with the route and its challenges. The second generator was hauled a week later in a trip that only took six hours.

Once construction of the substation is completed this summer, the two generators will produce a total of 20 MW of power, more than enough to serve critical customers and the surrounding area as needed, particularly during hurricanes and other storms.

Heavy Load Turns Heads in Tulsa

Last week, Barnhart’s heavy haul of a massive piece of equipment drew onlookers along the route in Oklahoma.

The 317,000 lbs. unit, known as a coker bubble tower, started at a fabricator in Sand Springs. Barnhart loaded it onto two 6+6 lines of Eastrac trailers, bringing the total weight of the load to 660,000 lbs. It was destined for the Port of Catoosa in Tulsa, 25 miles away.

The tower, which was a little over 170’ long, had to be maneuvered down narrow two lane roads, moving at an average speed of 15 mph. The back trailer was steered by a crewman and the load was pulled and pushed by two Western Star Prime Movers.

The load was also accompanied by the Oklahoma Highway Patrol and utility crews who helped move power lines and streets signs. The convoy was captured by News on 6 in Tulsa and other news outlets as it navigated the route.

The tower was successfully offloaded at the Port of Catoosa onto a barge headed for a refinery in Ohio. Once it reaches the site, two industrial cranes will be required to position and install it.

COLD WEATHER AND LOAD SIZE POSE A CHALLENGE IN HAUL PROJECT

Barnhart was hired to haul a 435,000-pound turbine to Dexter, Minn., a journey of over 1000 miles that originated in Alberta, Canada.

The turbine was brought to the border town of Sweet Grass, Mont. where it was staged on stands. It was then self-loaded to Barnhart’s GS-800 transporter, which brought the total size of the transport to 16’7” high, 18’ wide and 316’ long with a gross weight of 982,000 lbs.

At both the beginning and end of the journey, the trip was hampered by severe winter weather. Finding a route to accommodate the dimensions of the load was also a challenge, requiring multiple state and county permits. Two trucks assisted in pushing the load up steep grades and with maintaining an adequate speed.

The trip ultimately took 10 days for Barnhart to complete. Toward the end of the route, the team had to manage Frost Laws, seasonal restrictions that involve weight limits on roadways, where thawing pavement reduces load capacity. The final step was to offload and stage the turbine with 50-ton one-shot gantries to the client’s cribbing.

Christmas from the Moon

It was 1968, a year of tumultuous events, marked by the shocking assassinations of Robert Kennedy and Martin Luther King.

But as the year came to a close, millions raised their eyes to the skies for the hopeful message of Apollo 8, NASA’s lunar voyage. Manned by Astronauts Frank Borman, Jim Lovell and William Anders, Apollo 8 achieved a series of firsts for space flight and NASA.

The three astronauts became the first men to leave Earth’s gravitational pull, the first to orbit the moon, the first to view all of Earth from space and the first to see the dark side of the moon. Just seven months later, Neil Armstrong would become the first human to step on the moon.

But on Dec. 24, 1968, the crew had a special message to deliver in orbit.

“We were told that on Christmas Eve we would have the largest TV audience that had ever listened to a human voice,” recalled Borman years later. “And the only instructions that we got from NASA was to do something appropriate.”

During the broadcast, as the astronauts beamed back images of the moon and Earth, they took turns reading from the book of Genesis. Then they closed with the following wish, “Good night, good luck, a Merry Christmas and God bless all of you on this good Earth.”

The year 2017 was also tumultuous with natural disasters, political infighting and brewing international conflicts. Still, there is more that connects the people of this good Earth than divides us like love of family, community, the desire to help others, respect for hard work, achievement, decency and fairness.

During this holiday season, Barnhart wishes you the source of true peace on Earth in this video message.

Tips On Choosing the Right Size Crane

To properly size and select a crane for a job many factors must be considered to determine the right type of crane and corresponding capacity. Should it be a heavy lift crane? Boom truck crane? Rough Terrain crane? Weight and size of load, location, reach, obstructions, and other factors must be determined before choosing crane.

Here are some key steps:

  1. Calculate the maximum radius from the center of pin.
  2. Confirm the total weight of the load. If not known, consider consulting an engineering professional.
  3. Determine clearance issues, either height under ceiling or overhead obstructions.
  4. Allow for the height of obstructions between crane and load.
  5. Consider the hook height required with lifting equipment.
  6. Allow for the distance from jib head to the hook.
  7. Determine if obstructions will impede the counterweight when swinging.
  8. Verify if the crane will need to work around obstructions during set up.
  9. Discern whether specialized rigging equipment will be needed to avoid removing critical plant equipment during the lift.
  10. Consider what boom length will be required.
  11. Ensure whether the ground can support the crane. Further testing may be needed.
  12. Establish how the crane will access and leave the site. Are roads and entrances able to accommodate?

All these factors are essential to the process of selecting a crane for a safe and successful job.

PHOENIX BRANCH PLAYS UNIQUE ROLE IN EMERGENCY RESPONSE

Barnhart’s Phoenix branch occupies a unique niche. Nearly 68,000 square feet of its 72,000 square foot facility is devoted to storage of a very specific kind.

The facility acts as a response center for the SAFER (Strategic Alliance for Flex Emergency Response) program, storing $30 million of backup equipment for the nuclear industry in case of an emergency, including pumps, industrial grade fire hoses, generators, and lights that can illuminate five acres. This equipment would maintain safety functions for an indefinite period if an event disabled a plant’s installed safety systems. It has been preloaded on 46 trailers and, once deployed, can be at any nuclear facility in the United States within 24 hours.

The Phoenix facility houses $30 million of emergency equipment for the nuclear industry.

Barnhart’s football-field size storage facility is climate-controlled and has been upgraded to nuclear storage standards. Three full-time employees maintain and test the equipment on a regular basis.

The site is so essential to the program, it attracts an assortment of distinguished visitors.  Senators, congressman, industry executives and top U.S. and Japanese nuclear regulators regularly tour the facility.

NEW KENTUCKY BRANCH OPENS TO BETTER SERVE CUSTOMERS

Barnhart has opened a second location in Kentucky with a new facility in Calvert City, joining Owensboro in the Bluegrass State.

“While we have been providing crane and rigging services and heavy transportation in the Calvert City area for many years, we can better serve customers in western Kentucky, southern Indiana and southern Illinois from this new operation,” said Clay Ellis, Barnhart’s branch manager for Owensboro.

Barnhart offloads a deethanizer at a chemical plant in Kentucky.

The new branch will focus on providing service to the chemical and power industry.  Area customers will also have access to an inventory of local cranes ranging from a 60 to 600-ton capacity, as well as specialized rigging equipment like cantilever beams, gantries, slide systems, SPMT’s, and other larger project equipment.

In addition to Calvert City, Barnhart has more than 45 other branches nationwide, including locations in the region in Tennessee and Illinois.

WATERWAYS JOURNAL FEATURES LOCK AND DAM PROJECTS

Barnhart has been busy addressing critical infrastructure needs at waterways across the southeast. Their work on three lock and dam projects, including one featured in a blog last month, was recently profiled in Waterways Journal.

These projects utilized both traditional and nontraditional methods for repair and replacement. Traditional work involves a floating crane, while nontraditional methods refer to rigging methods that rely on a structural system across the gate walls.

For a recent project in Kentucky that was featured in the article, Barnhart used traditional methods to replace a set of miter gates. The old gates were scrapped and the new gates were lifted from a transport barge and set using Barnhart’s adjustable rigging link system and a LR 1700 barge crane. No land side support was needed as all operations were self-contained to the barge and river.

Barnhart uses a traditional method in this lock and dam project in Kentucky.

A separate project in Alabama used a nontraditional approach. The work was performed using a modular lift tower and a girder system, which spanned the 110’ width of the lock, in conjunction with a 500-ton hoist and slide system.

In the Waterways article, Jeff Latture, Barnhart’s senior vice president was quoted as saying that often project planners don’t consider nontraditional options because they are usually less familiar with those methods.

However, he urged consideration of this approach. “Depending upon the scope of the project, using nontraditional methods could be a safer option and provide lower overall costs.”

Kentucky Project Enlists Services of Big Al

A project at a lock and dam in Kentucky required Barnhart to bring out the big guns, otherwise known as Big Al.

Big Al is Barnhart’s barge-mounted heavy lift crane based in the Port of Mobile in Alabama. It was created because of a need for its super-capacity, an ability to lift loads of over 400 tons. The project at the dam involved lifting two 468,000 lbs. miter gates.

Barnhart mobilized Big Al, traveling up the Tombigbee/Tennesse River via tug to Paducah, Kentucky and then further up the Ohio River. The trip took 13 days to complete on a project with a tight time frame.

At the site, the old gates had been removed by the Corps of Engineers, while the new gates had been delivered by deck barge. Barnhart put Big Al to work, using its ARLS (adjustable rigging link system) to accommodate the two gates. Barnhart attached specialized turning shoes, utilized Big Al to lift the gates from horizontal to a vertical position, and rough set each gate at a 135 ft. radius.

Once the job was completed, ahead of schedule, Big Al was demobilized and made the return trip via waterways back to Mobile.

ENGINEERING KEY TO R & R PROJECT SUCCESS

A pulp and paper mill in Alabama needed to replace a 28’ long X 8’ diameter, 34,000 lb. deaerator. The unit was located just below the roofline of a 100’ tall building.

The traditional method of lifting the piece through an opening in the roof could not be done due to overhead piping that would not only be costly to remove, but would completely shut down production at the mill.  The deaerator would have to be accessed through a hole the customer cut in the side of the building.

It was a job for Barnhart’s movable counterweight system, but the reach of the beam in its normal configuration wasn’t long enough. Barnhart’s engineering team got involved to modify the system and add extensions to give it its necessary length.

In addition to engineering challenges, there were tight clearances in the mill alleyway to set up a 600-ton hydraulic crane and assemble the system, plus just 7′ of overhead clearance above the unit. Still, the old unit was successfully removed and the new unit set to anchor bolts inside a building that was operational.  The job was completed a day ahead of schedule.
