Transport and Setting of Turbine/Generator in a North Carolina Project

Market: Power

Location: North Carolina


The Challenge

Barnhart Crane & Rigging Co. won a bid on an already-in-progress job, which included the hauling, lifting, and setting of steam equipment, and the customer urged the team to finish the job on a very tight schedule. On top of that, very wet and extremely cold weather made the project even more difficult, not to mention a very constricting site gave the crew very little real-estate in which to work.


The Solution

Creative planning, hard work, and timely deliveries all helped Barnhart meet the deadline. In addition, clever engineering enabled the team to connect the Marino girder to the Barnhart gantry track, and as a result, saved much time and money.

The Description

The customer contracted Barnhart for the onsite transporting and setting of the turbine in addition to a generator. The job required the team to lift, haul, and set these massive pieces to an alternative location on the job site.

The project was already underway when the crew won the bid, and the customer desired a quick finish. Barnhart engineers then focused on quickly submitting the project plans. Other engineers on the site also flooded the team's engineers with questions, and Barnhart's quick responses kept the job on schedule.

Barnhart's engineers also developed a plan to connect the Marino girders with the Barnhart gantry tracks. This allowed the team more flexibility and availability with its equipment and saved quite a bit of time and money.


The rest of the crew suffered through cold and wet weather. In fact, the site conditions heavily constricted the equipment because of minimal space to navigate machinery. The crane operators and workers pressed onward with hard work and overcame the dreary setting.

A subcontractor also delivered integral parts and equipment to Barnhart right on schedule. This timely delivery, matched with Barnhart's creative engineering staff and diligent crew, allowed Barnhart to start a job behind schedule and finish ahead of the deadline.

Major Equipment Used

  • Goldhofer Trailer
  • Stator Frame
  • 500T Hoist

Despite Difficult Hurdles, Barnhart Races to Quick Finish in Generator Heavy Haul

Market: Power

Location: Tennessee


The Challenge

A customer called on Barnhart Crane & Rigging Co. in the "11th hour" for a heavy haul job, including the transportation of three combustion turbines and three combustion generators. One of the most difficult routes a Barnhart team has ever maneuvered and the need for a quick permit obtainment called for a perfect performance by the company.

The Solution

Barnhart quickly secured the required permits from the State of Tennessee for this difficult job. After quickly obtaining the permits, Barnhart won the job for the original bid value, but that only allowed them to leap the first hurdle in this job.

Next, Barnhart's careful planning, ingenuity, and friendly negotiations helped them save time, secure their routes, make tight turns, and safely navigate steep hills and narrow roadways.

In fact, Barnhart conducted numerous pre-mobilization and operation meetings, in addition to daily job hazard analyses, to successfully complete the job.


The Description

After being called in late by the customer, Barnhart won the bid on the heavy haul job because they quickly secured the required permits while the competitor failed to do so. Friendly relations with the state and a commitment to safety and government guidelines quickly allowed the team to obtain the permits.

The original schedule for the job called for a delivery every ten days. However, the team compressed the schedule to one delivery every seven days to ensure timely completion. This seems even more impressive when one considers the team covered a 74-mile haul route and two cities during every delivery.

The crew faced its first obstacle with a faulty railroad crossing. A careful inspection led to an engineering effort to shore up the bridge, ensuring a safe crossing.

Next, Barnhart negotiated terms with a do-it-yourself car wash because the car wash blocked Barnhart's route on a tight turn. The car wash agreed to demolish the building, and the trailers safely maneuvered the turn. In fact, the road on which the car wash sat was perhaps the tightest road Barnhart has ever had to squeeze through!

The last part of the route included a five percent grade and a road width of nineteen feet. The dolly transport itself stretched just under eighteen feet wide! After numerous meetings and careful transport, the team safely completed the job.

Barnhart's hard work and careful planning ultimately led to an extraordinary achievement with this job. Despite the tight schedule and daunting obstacles, the team managed a near perfect performance!

An Unwieldy Dome Did Not Circumvent Barnhart's Efforts to Successfully Complete Removal

Market: DOE

Location: Washington


The Challenge

A customer contracted Barnhart Crane & Rigging Co. to remove a containment dome. However, the thin walls of the dome caused the dome to flex and bend during removal, making the project very difficult to complete.


The Solution

The Barnhart team engineered temporary hold-down and tightening brackets to stabilize and easily remove the dome.


The Description

A customer assigned Barnhart to two tasks: removing a containment dome and transporting a polar crane. The dome extended 80 feet in diameter and weighed around 145,000 pounds.

The team conducted a shell analysis on the dome and found the dome to be thin and flimsy. The shell analysis led the team to engineer the appropriate brackets described above and to locate the best rigging attachment points.


Barnhart's subcontractor, Cutting Edge Services, cut the dome using a large wall saw. Once the subcontractor cut the dome, Barnhart used a CC1800 SSL crawler crane to place the dome on the ground.

The team lifted the polar crane to a transporter for shipment. And the customer left the dome on the ground to be cut into pieces for easier shipment.

Although the project lasted several months, Barnhart's expert engineering and well-trained staff finished the project ahead of schedule with no injuries.

  • CC1800 SSL Crawler Crane
  • THP Trailer

Transformer Offload, Transport, and Replacement

Market: Power

Location: Mississippi


The Challenge

A customer contracted Barnhart Crane & Rigging Company to receive, offload, and stage four 520,000 pounds Hyundai transformers in Mississippi for the 2012 Extend Power Uprate (EPU) outage in 2012. Potential problems with the dock, where the Barnhart team would offload the massive EPU equipment, put a small hiccup in the schedule.


The Solution

The water at the roll off site suffered from siltation pollution. This simply means that the water contained higher concentrations of sediments and soil buildup than normal. This problem brought the dock's integrity into question, but a professional engineering review found the dock's structure perfectly stable to withstand very heavy weights.


The Description

The EPU outage allows the power plant to update their components and equipment in order to produce more power. The customer contracted Barnhart to help with the power plant's uprate.

After finding the dock to be absolutely safe, Barnhart assigned its newest fleet addition, the LR 1700 Barge Crane Big Al, to the task of offloading the massive transformers.

The Barnhart team than loaded the four transformers to a 195' x 35' deck barge that eventually hooked up with Big Al at a local port.

Once the team secured the barge to two dolphins near the new dock destination, the crew spent a day in setting up the ballasts for lifting operations. Big Al then successfully relocated the huge transformers from the barge to an awaiting 16-line PSTe trailer on the dock. By using Big Al's nifty winch system, the team perfectly aligned the transformers atop the Goldhofer.


The trailer transported the four transformers to a staging location just a short distance south of the dock. The intermediate staging allowed the Barnhart crew to offload all four transformers in a single day!

Next, Barnhart will move the transformers to a much more distant staging location, where the team will dress them out in preparation for the upcoming EPU. During this scheduled EPU outage, the team will replace the plant's old transformers with the new ones Barnhart has transported.

Major Equipment Used

  • LR 1700 Barge Crane "Big Al"
  • 16-Line Goldhofer PSTe Trailer

Traveling Screen and Stoplog Removal from Reactor Pump

Market: DOE

Location: Washington


The Challenge

A customer contracted Barnhart to remove six traveling screens and one stoplog from a nuclear reactor pump hose. The original contractor unsuccessfully removed the traveling screens because decades of immobility tightly wedged the screens in the filtering system.


The Solution

Barnhart's top of the line pull-up gantries allowed the team to shake the screens loose, remove them from the pump hose, and successfully complete the job.


The Description

Originally, the customer contracted a competitor to remove and dispose of the old traveling screens and stoplog by means of a 2250 crawler crane. Nuclear reactor pumps use traveling screens as a net to collect debris from incoming water, and a stoplog allows the engineers to adjust the amount of water flow into the pump.

The customer wished to retire the old equipment, but however, as stated above, the numerous years of wear-and-tear lodged the screens in place. The customer and competitor invited Barnhart Crane & Rigging Company to assist in the project's completion.


The project leaders originally thought that the screens weight may have exceeded the crawler crane's capacity, in addition to the screens' firm positions. Barnhart brought in a Pull-up Gantry that effectively dislodged the stubborn traveling screens.

As it turns out, the stuck screens were the only problem, as the other team easily removed the screens with the 2250 crawler crane. Similarly, Barnhart used the pull-up gantry along with climbing jacks to initially unfasten the stoplog, and the other team successfully removed it with the same crawler crane.

  • Pull-up Gantry
  • Climbing Jacks

Barnhart Makes Special Appearance in 2011 Super Bowl Commercial

Most of us are aware of the product placement advertising that sneaks its way into popular television shows and movies. In fact, the clever folks at Bud Light poked fun at the marketing methods during this year's Super Bowl commercial lineup:

But does product placement work in commercials themselves? I don't think many marketing teams have attempted it.

However, Chrysler's 2011 Super Bowl commercial "Imported from Detroit," featuring Rap Artist Eminem, inadvertently promoted Barnhart Crane & Rigging Company with a quick product placement shot.

That's right. Those are official Barnhart cranes. You can't see the Barnhart name, but they made the commercial.

Here's the full commercial below. The crane shot appears in the first ten seconds of the video.

Feedwater Heaters and Rotor Replacement

Market: Nuclear

Location: South Carolina


Extremely tight quarters and equipment limitations slowed down the project.


Quick thinking and new basketing devices helped complete the job.


Barnhart was contracted to remove and replace rotors and feedwater heaters. The rotor was railed to site, offloaded with the 44A system, and transported easily to the crane bay.

However, when the old rotor was loaded to a nine-line trailer for transporting to storage, the crane failed at a height of nine feet off of the ground. With engineering approval, we were able to load crane mats (five high) on the trailer and safely rescue the rotor from the inoperable crane.

After that, we quickly finished the remainder of the job.

Moving the feedwater heater challenged us as well. The 4B sat under a floor and we slid it out using a light slide. Furthermore, we inverted both the 4A and 4B to clear surrounding obstructions.

We used the new basketing devices on their maiden voyage and found that they were easy to use, and that they served their purpose well.

Next, we directed them through the legs of the gantry crane, between the MSR's, down a low risk path on the Turbine Deck, and finally to the crane bay.

With the successful nuclear project, four employees gained their "nuclear" badges, making them invaluable help for future nuclear jobs. They will be particularly helpful to speed up our work in case we need faster reaction time.

Four Types of Equipment, Seven Bridges, and Forty Miles Add up to Another Barnhart Transport Success

TEXAS - In August 2010, a customer hired Barnhart Crane & Rigging to transport a demethanizer and absorber from Houston to Sanderson. As they finished an almost identical job a year earlier, the crew not only had all the right equipment for the job but also the best experience to ensure yet another Barnhart success.

"We did this same project a year earlier," project manager James Weston said. "And even though the pieces were heavier, the method was still the same."

The team began at a Houston shop, where they used pull-up gantries to load the pieces on to 26-lines of Goldhofer PSTe. The platform trailers relocated the pieces to the nearest rail spur. From there, rail carts moved the pieces to Sanderson, and Barnhart used pull-up gantries and the slide system to place the pieces on the trailers.

The absorber, however, was much heavier than the demethanizer, which caused Weston and his team to configure a new trailer system: 30-lines THP dollies with a 16-dolly hybrid system. After the configuration was approved, the design eased the absorber's transport over a 40-mile haul, including seven bridges.

Weston noted the weight difference as the only hiccup in the move.

"Weight changes made this project different than its twin project done a year prior," Weston said. "So all the knowledge we thought we had going into the project was short lived with the increase of the piece weight. However, we made the necessary adjustments and were able to have the piece on the road within a week of learning of the new weights."

The weight change hardly set the crew back, as they compensated for the slow-down by promptly communicating with their vendors and pre-staging the equipment.

"We notified all the vendors of the pieces' arrival and coordinated the rail siding prior to vessel departure in Houston," Weston said. "Upon arrival, we were able to pre-stage equipment to ensure a timely off load of rail and transport to the job site."

The demethanizer, on the other hand, was slightly lighter, and the team returned to the railroad to place it on the original 26-lines trailer and 14-dolly hybrid system design.

But what made this project so special? Weston believes that Barnhart has a distinct advantage over its local competitors.

"With the knowledge of the bridges from the last job done a year prior, Barnhart had a leg up on the competition by already knowing the best methods to employ and already knowing what equipment would be necessary to achieve a successful project," Weston said. "And in the Houston Market, we do have some stiff competition with the heavy haulers and heavy lift companies. However Barnhart prides itself with having the necessary equipment, personnel, and expertise to ensure a project runs as planned."

Past experience, specialized personnel, and custom equipment all helped make this a special job, but Weston saw the relationships Barnhart made with the community as the most impressive aspects of this project.

"There are many projects where we are transporting a long distance and then there are times we are stationary in one location for an extended period of time," Weston said. "By being stationary you are able to meet and build relationships with the town's people and become a part of the community."

The small town of Sanderson provided the perfect Petri dish for comradery.

"Sanderson is a small town with about 500 residents," Weston said. "At no time did we go a day without someone asking us about the progress of the job or really being involved in the job itself. The local sheriff's office, the volunteer fire department, and some local businesses supported us in whatever we needed. It is nice to know that we have left a lasting impression in the community and that a lot of friendships have come from that."

Heavy Industry Reports, Barnhart Ranks in Top 10 North American Companies and Top 25 Internationally

In June 2010, American Cranes and Transport (ACT) published their annual top 100 Crane and Transport companies for the year. The criteria for this list include the number of company employees and branches, scope of operation, number of mobile and crawler cranes, and a company's largest crane and its capacity.

Although the list intends to survey the heavy industry as a whole, the rankings do provide some idea of the big players in the crane and transport markets. Barnhart Crane & Rigging Company maintained a top 10 position even after the rough economic downturn known as 2009. The 2010 top 10 included the same companies as 2009.

Another crane publication, International Cranes and Specialized Transport (IC), also conducted its own survey over the international market. Although their criteria are similar, they place a heavier emphasis on crane capacity in ranking the top 50 international companies. The IC ranks companies according to an index calculated as the total maximum load moment rating, in "tonne-metres," of all cranes in a companies' fleet.

In the IC report published in August 2010, Barnhart stood impressively at the 24-spot. Other than Barnhart, only seven other U.S. companies made the top 25.

The IC also named the top 12 companies with the largest single cranes, and Barnhart's Demag CC 4000 RL ranked seventh with a capacity of 1,800 tons. The next IC rankings will debut during this quarter of 2011.

The ACT and IC reports are only available through purchase at the KHL website.

Building Casks

Market: Power

Location: Washington


Special canister required for waste removal project was difficult to maneuver into place.


The added length of the tipstick hanging from the overhead crane allowed the waste container to be placed in the shipping container.


A nuclear research facility is in the process of demolition and deactivation of buildings. The building was used as a spent-fuel metallurgical test facility. Some of the waste from that process were to be removed from the building to allow demolition and deactivation activities to continue. The high-level waste dose rates and concentrations required removal from the building in a special shipping canister. The truck that hauled this canister could not back into the building far enough for the overhead crane to reach the canister. Barnhart solved the problem by hanging the tipstick from the overhead crane. The added length of the tipstick provided enough distance to allow the waste container to be placed inside the shipping canister. The process involved disassembling the canister, installing the inner waste container, and reassembling the shipping canister. Two canisters were loaded. The waste was then shipped out to the repository onsite for long-term storage.

Blow Down Drum Roll, Please…

TEXAS – Barnhart Crane & Rigging Company completed yet another heavy machinery relocation in March, 2010. A customer tasked Barnhart and its crews to transport a massive Blow Down Drum measuring a grand 62’6” in length, 23’2” in width, and 22’9” in height.

From Houston, the crew needed to move the drum to a Texas dock, from which the barge would meet another Barnhart team in Detroit. And like most Barnhart projects, time was of the essence for the team.

“The piece was due to meet a barge that was coming in from Mexico that had pieces already on it and all items were then headed to Detroit, Mich.,” said project manager James Weston. “Any delay in shipment could be very costly with the barge and tug waiting.”

To speed up project completion, Barnhart devoted special care to route planning and ensured the quickest possible route between transport sites. The due diligence in route planning reduced the mileage in addition to cutting costs in half. In fact, the route the crew used had never been utilized before, and the customer was surprised and impressed that the load quickly cleared all sharp turns, underpasses, railroads, and bridges.

On top of the time constraints, the customer awarded the project to Barnhart at the last minute. Weston and his team quickly made all the necessary arrangements with vendors to expedite the transport.

“We contacted our vendors in a timely manner,” Weston said. “And with the help of the utility companies and other outside agencies, we were able to mitigate obstacles prior to beginning the haul. That left us only having to deal with a minimum set of obstacles.”

Because of Barnhart’s longtime presence in Texas, they have developed strong relationships with the Department of Transportation and other partner companies. For moving the massive drum, those relationships came in rather handy.

“The majority of those companies take the time to meet with us, run the routes, and often suggest better ways to achieve the ultimate goal,” Weston said. “Having a team mentality betters the overall outcome of a project.”

The relationship with the DOT, in particular, allowed Barnhart to quickly obtain the necessary permit for transport, set up all vendor contracts, and meet the barge on time.

Weston likewise noted that having these strong local relationships really gives the customer great confidence in Barnhart’s work.

“It benefits the customer over time by knowing they have companies that work well together as a team and by understanding everyone is there to achieve the same goal,” Weston said.

Barnhart’s industrious planning, its prompt arrangements, and its commercial partnerships weren’t the only impressive aspects of the project, according to Weston. The project illustrated the efficiency and teamwork that Barnhart’s nationwide company has to offer.

“Barnhart has 23 branches across the county,” Weston said. “And every day we work together to ensure that we are doing what we can to help our brethren branches. This job speaks highly to that. Expediting this shipment enabled our Chicago branch to have a successful kick off to their project at Marathon in Detroit.”

No Short Circuits for Barnhart in Transformer Replacement at Kansas Power Plant

Miserable weather and poor conditions did not thwart Barnhart Crane and Rigging's success when installing a massive 500-ton transformer at a Midwest power plant. Although taking the old transformer out posed no problems, installing the new transformer proved to be quite a challenge.

Fortunately for the power plant and customer, Barnhart loves to take on challenging jobs. Project Manager Bob Possel later explained why this project was so exceptional.

"We typically don't change out 500-ton transformers," Possel said. "I would say the typical transformers that we handle on average are approximately 200 tons."

To unload the Transformer from the Schnabel railroad car, Barnhart employed four 300-ton jacks, pull-up gantries, and a slide system. The staff slid the transformer to a ten line double-wide hydraulic platform trailer. At the request of the owner, the crew staged the component on slide beams so the transformer could be partially dressed out prior to the outage.

During the outage time was saved. A second Barnhart crew mobilized to site to slide the transformer across the road during the night for staging. However, the crew ran into a significant hurdle that tested the team.

"The new transformer was significantly heavier than the old one causing ground bearing issues," Possel said.

To overcome this issue, the team strategically placed additional matting to resolve the problem. Timbers, along with an extra truckload of steel crane mats, provided the timely solution.

Barnhart ultimately completed the project safety and in a reasonable amount of time, all to the satisfaction of the customer.

"The customer was pleased with our services," Possel said. "[He] wants us to replace a similar transformer at another plant."
