The $380,000 Excavator Couldn’t Lift the Bridge Beam — Her 1959 Euclid R-27 Set It Clean…
340 people were standing on the gravel access road along the eastern bank of the Cutter Creek drainage on a Tuesday morning in late September of 2022. And most of them were watching a $380,000 Komatsu PC 800 hydraulic excavator fail to do the one thing it had been brought there to do.
The beam was a W 36 by 210 wide-flange steel section, 44 ft long, 1,160 lb per linear foot, and it needed to be set into the bearing seats of a county road bridge replacement that had been 14 months in the planning and 6 weeks behind schedule before that morning even started.
The Komatsu had a manufacturer-rated lift capacity of close to 90,000 lb at a 10-ft radius. The math said it could do the job. The ground said otherwise. The access road was a reclaimed gravel path over a subsurface that had been saturated by 3 weeks of September rain.
And every time the operator swung the boom out over the creek bank and brought the load to tension, the machine’s left track broke through the compacted surface, and the whole rig settled at an angle that the load charts did not allow.
The operator tried twice. The site supervisor tried a third time himself. The beam sat in the staging area on its timber cribbing, 44 ft of steel going nowhere, and the general contractor’s project manager was on the phone with the equipment rental company trying to figure out what a second mobilization would cost and how many more days the county road closure would extend.
That is when Della Marsh backed her 1959 Euclid R-27 down the county road and asked the flag man where he wanted her to set up. She had driven it 41 miles from her property outside of Mosback, Tennessee, on a lowboy trailer pulled by a 1988 Peterbilt 379 that she owned outright and maintained herself.
And she had not been called by the general contractor, or by the county, or by anyone in an official capacity. She had been called by a man named Curtis Yellin, who ran the county road crew and had worked alongside her father for 11 years before her father died.

And Curtis had called her at 6:15 that morning from the site and said four words into the phone. He said, “Della, they need you.” She had been in her shop at the time doing valve clearance work on the Euclid’s C6 engine, and she had put down her feeler
gauge, wiped her hands on a shop rag, and said, “Give me 2 hours.” Now, I need to stop here and explain something, because if you look at a 1959 Euclid R-27 without knowing what you’re looking at, what you see is an old machine.
You see yellow paint that is faded to the color of old mustard and cracked in the seams. You see a cab that sits high and square and looks like it was designed by someone who had never heard of aerodynamics, which is accurate, because aerodynamics were not a priority in 1959 for a machine built to move earth at mine sites and heavy construction.
You see a machine that is 63 years old on the morning we are talking about, and you see it parked on a county road next to a $380,000 piece of modern hydraulic equipment that has the word Komatsu on it in letters 8 in tall, and the contrast is not subtle.
Several people on that job site laughed. One of the Komatsu’s crew members, a man in his early 30s wearing the equipment rental company’s branded jacket, said something to the person standing next to him that I will not repeat here, but that was audible to at least four people nearby.
The project manager looked at the Euclid and then looked at Curtis Yellin with an expression that asked a question he did not say out loud. What none of them knew, and what I’m going to tell you now, is what that machine actually was.
But first, I need to tell you about Della Marsh, because without knowing who she is and where she came from, the rest of this story is just an old machine doing something surprising, and that is not the story.
Della Marsh was 41 years old in September of 2022. She had grown up on a 48-acre property outside of Mosback that her grandfather had bought in 1961 with money he had saved working in the coal handling operations at the Kingston steam plant.
And the property had stayed in the family through two generations of careful stewardship and one near foreclosure in 1987 that her parents had resolved by selling 12 acres to a neighbor and paying the bank in full on a Monday morning in March.
She had never attended college. She had attended a vocational program in diesel and heavy equipment mechanics at a community institution in Harriman for 2 years, graduated at the top of her program, and gone directly to work at a road construction company in Rockwood, where she spent 8 years
running equipment and learning the mechanical side of the operation from a man named Harlan Pope, who was the company’s lead equipment mechanic and who had been working on heavy iron since 1971.
Harlan Pope had a way of explaining mechanical systems that Della would later describe as the most valuable education she had ever received. And the way he explained it was this.
He would put his hand flat on the side of an engine block, and he would say, “Listen to it. It will tell you what it needs.” She had thought this was metaphor when she was 22.
By the time she was 30, she understood he meant it almost literally. She left the Rockwood company in 2010 when Harlan Pope retired. Not because the work was bad, but because Harlan was the reason she had stayed, and his absence made the job feel like a building with the load-bearing wall removed.
She went out on her own. She registered a sole proprietorship, bought a used lowboy trailer and the Peterbilt, and began offering equipment transport and heavy rigging services to road contractors and county operations across a four-county area.
She worked alone for the first 3 years. She took on a part-time helper, a young man from Wartburg named Danny, who loaded and unloaded equipment and kept the Peterbilt’s logbooks in 2013.
She bought the Euclid in 2014. The Euclid R-27 had been sitting in a field outside of Oneida since 1989 when the mining operation that had last used it closed. It had been sitting there for 25 years.
The tires, which on an R-27 are not the tires of a standard excavator or crane, but rather the oversized rubber of a machine designed to carry its own enormous weight on soft ground, had deflated and cracked and partially returned to the earth.
The cab glass was gone. The engine had not turned over in a quarter century. The hydraulic lines had dried and split. A family of raccoons had been living in the cab for at least two seasons based on the evidence.
Della bought it for $4,200, which was essentially the scrap value, and she bought it from the estate of the mining company’s former owner, who had died in 2011, and whose son wanted the field cleared.
She spent 14 months rebuilding it. She did the work herself in the evenings and on weekends in the shop behind her house on the Mosback property. She sourced parts through a network of heavy equipment dealers and salvage yards that she had been building relationships with for a decade,
and she sourced them slowly and carefully, buying only what was correct and refusing to substitute when the correct part was unavailable. She rebuilt the C6 engine from the crank up.
She replaced every hydraulic line in the system. She rebuilt the pump assembly. She replaced the cab glass with custom-cut polycarbonate because the original specification glass was no longer manufactured. She rebuilt the boom cylinders.
She replaced the final drives. She painted it herself in the original Euclid yellow using a spray gun in her shop with the doors closed against the November wind. When she was finished in the spring of 2016, she had spent an additional $22,000 in parts and materials on top
of the purchase price for a total investment of $26,200 in a machine that she had returned to better than original mechanical condition. The project manager on the Cutter Creek job did not know any of this.
He knew what he saw, which was an old yellow machine on a lowboy trailer, and he knew what his schedule said, which was that he was already 6 weeks behind and could not afford another day.
He let her unload because Curtis Yellen had vouched for her and because he did not have a better option in front of him. Now, here is what I need you to understand about the Euclid R-27, and I need you to stay with me for a few minutes because this is the part that explains everything that happened afterward.
The Euclid R-27 was not designed to be fast. It was not designed to be elegant. It was not designed to compete with modern hydraulic excavators on cycle time or fuel efficiency or operator comfort.
It was designed to do one thing with absolute reliability, and that thing was to move extraordinarily heavy loads in conditions where the ground itself was not cooperating. The machine was built for mine sites and major construction operations in an era when the philosophy of heavy equipment design was
rooted in mechanical redundancy and oversized components that would tolerate abuse and in ground pressure management that modern machines, with their narrow tracks and concentrated weight, have largely abandoned in favor of speed and transport convenience.
The R-27 weighs, in its operating configuration, approximately 94,000 lb. That number sounds like a disadvantage until you understand what it means for ground pressure. The machine’s track system, which is wider and longer than anything you would see on a modern excavator of comparable lift capacity, distributes that weight across a contact area that is roughly three times the footprint of the Komatsu PC 800.
On saturated ground, on reclaimed gravel over soft subsoil, on the kind of surface that was eating the Komatsu’s left track that morning, the Euclid does not sink. It spreads. The weight that would punch through a concentrated footprint instead distributes across enough surface area to stay on top of what is underneath.
This is not an accident of design. This is the design. The engineers at Euclid who built this machine in 1959 were solving a specific problem that the mining industry had been dealing with for decades, which is that the ground at mine sites and major earthmoving operations is almost never the kind of ground that a machine’s theoretical capacity assumes.
The theoretical capacity assumes solid, compacted, level ground. The real world offers saturated clay, reclaimed fill, and access roads that look stable until they are not. The R-27 was their answer to the real world.
The hydraulic system is a separate lesson. The R-27 uses a load-sensing hydraulic circuit that, in 1959, was ahead of what most equipment manufacturers were building. The system modulates pressure continuously based on actual load demand rather than running at a fixed high pressure and throttling flow, which means that at maximum lift load, the system is delivering exactly the pressure the load requires and no more.
This matters because hydraulic systems that run at fixed high pressure generate heat, and heat in hydraulic fluid changes viscosity, and changed viscosity changes the precision of the cylinder control. On a long, slow, precision lift, the kind of lift required to set a 44-ft bridge beam into bearing seats with a tolerance of less than a quarter inch, the temperature management of the hydraulic circuit is not a detail.
It is the operation. There is one more thing. The boom geometry on the R-27 is a long-reach configuration that was standard on mine site equipment of that era, designed to place loads at significant horizontal distance from the machine’s center line without the load path crossing directly over the tracks.
On the Cutter Creek site, the bearing seats on the far side of the creek were at a horizontal distance from the nearest stable ground that had put the Komatsu’s load chart outside its safe operating envelope the moment the ground started moving.
The R-27’s geometry put the load path inside its envelope with room to spare. Della knew all of this. She had known it since the first month she spent with the machine, reading the original engineering documentation that she had obtained from the Euclid historical archive through a correspondence that had taken her 3 months to complete.
She had the documentation in a binder in the cab of the Peterbilt. She had read it enough times that she could recite the load charts from memory. The project manager did not ask her any of these questions.
He pointed at the beam and pointed at the bridge and said, “Can you set that?” She looked at the beam. She looked at the bridge. She looked at the access road and the creek bank and the saturated ground and the bearing seats on the far side.
She said, “Yes. ” He said, “How long?” She said, “Depends on how long it takes your crew to rig it correctly.” He did not have an answer for that, so he went to find his rigging foreman.
The morning had gone to 10:45 by the time the beam was rigged. Della had walked the approach twice, probing the ground with a steel rod she kept in the Peterbilt’s toolbox, marking the track path with small orange flags she pressed into the gravel herself.
She had spoken to Curtis Yellen for about 4 minutes, standing at the creek bank, and their conversation was quiet enough that no one else heard it. She had gone back to the Euclid and spent 12 minutes making adjustments to the boom angle and checking the hydraulic fluid temperature.
She had not spoken to the project manager again. The Komatsu crew had moved their machine to the far end of the staging area. The rental company’s representative, who had arrived on site at around 10:15 to assess the situation, was standing near the Komatsu with his arms crossed and his phone in his hand.
He was watching the Euclid the way you watch something you expect to confirm what you already believe. At 10:57 in the morning, Della Marsh climbed into the cab of the 1959 Euclid R-27, started the engine, and let it warm up for 4 minutes.
I want to tell you what that engine sounds like because it matters. The C6 is a straight-six diesel, and in the configuration Della had rebuilt it with the injection timing she had set and the injectors she had cleaned and calibrated and the governor she had rebuilt from a kit she sourced from a retired Euclid dealer in Ohio, it does not sound like a modern diesel.
It does not have the high-frequency clatter of a modern common-rail injection system. It has a lower, rounder sound, a sound that comes from a longer stroke and a heavier flywheel and a combustion event that takes slightly more time to complete than modern high-pressure injection allows.
It is a sound that the older men on that job site recognized and the younger men did not. Curtis Yellen, standing at the creek bank with his hands in his jacket pockets, closed his eyes for about 3 seconds when he heard it.
She brought the machine off the lowboy staging area and onto the access road approach at 11:01. The tracks settled into the gravel surface and held. The ground pressure was doing what the engineering said it would do.
She positioned the machine at the mark she had flagged, set the travel locks, and brought the boom around to the rigged beam. The hookup took 2 minutes. She checked the rigging herself, climbing down from the cab to walk the sling attachment points, checking the shackle pins with her hand.
She climbed back up. She brought the load to tension. The chain did not snap taut the way it does when an operator is in a hurry. It came to tension the way a bow comes to full draw, gradually, with deliberate control, the slack leaving the system in a
smooth, continuous motion until the slings were carrying load and the beam’s timber cribbing was still touching the ground by about an inch. She held it there for 30 seconds. She was checking the ground under the tracks.
She was checking the hydraulic pressure gauge. She was listening to the engine note, which had dropped a half step as the load came on and then steadied, the governor doing its work, the rpm holding in the band she wanted.
The beam came off the cribbing at 11:09. It came off clean. No swing, no oscillation, no sudden transfer of load that would have started the pendulum motion that kills precision lifts.
It came off the way a surgeon lifts a retractor, controlled, deliberate, the result of understanding exactly where the center of gravity was and positioning the lift point accordingly. The beam hung level within a degree of horizontal, which for a 44-ft steel section is the kind of result that makes rigging engineers stop talking.
She began the swing at 11:10. The Euclid’s swing drive is slow by modern standards. A modern excavator can swing its upper works at 8 to 12 revolutions per minute. The R-27 swings at roughly four.
This is not a limitation. On a precision bridge beam placement over a live waterway with bearing seat tolerances measured in fractions of an inch, four revolutions per minute is the correct speed.
Eight revolutions per minute is how you damage bearing seats and break things and extend your schedule by another 3 days. The project manager, who had been watching from near the site trailer with his arms crossed in a posture that had not changed since Della arrived, uncrossed his arms at approximately 11:11 and took three steps toward the creek bank.
The beam cleared the creek bank at 11:13. It was moving over open water at this point. 44 ft of steel suspended from a 63-year-old machine on a saturated access road, and the machine had not moved.
The tracks were exactly where she had placed them. The left track had not broken through. The right track had not shifted. The ground was doing what she had predicted it would do because she had measured it and calculated it, and she had been right.
The near bearing seat received the beam’s west end at 11:15. It settled into the seat with a sound that the rigging foreman, a man named Alvaro, who had been doing this work for 22 years, later described as the cleanest seat he had ever heard.
A single low note of steel on steel with no bounce, no secondary contact, no adjustment required. The east end came down 30 seconds later. Alvaro checked the bearing plates with a tape measure.
He checked them twice. He looked up at the cab of the Euclid, and then he looked at the project manager, and he held up his tape measure and said nothing, which was its own kind of statement.
The beam was set at 11:16, 17 minutes from first lift to final placement on a job that had been stalled since 7:30 that morning. Della shut the engine down at 11:17.
She sat in the cab for a moment, her hands on her knees, looking at the bridge. Then she climbed down. She walked to the beam end and looked at the bearing plate herself, bending at the waist to sight along the steel, checking the alignment the way she would
check a valve clearance, not because she doubted the result, but because checking is what you do when you care about the work. She straightened up. She put her hand flat on the web of the beam the way Harlan Pope had taught her to put her hand on an engine block.
She held it there for a moment. The rental company’s representative had put his phone in his pocket. He walked over to where Della was standing, and he said, “What year is that machine?” She told him.
He said, “Who rebuilt it?” She said she had. He looked at the Euclid for a moment, and then he looked back at the bridge, and he said, “Huh.” Then he walked back to the Komatsu.
The project manager came over at 11:22. He said, “What do I owe you?” She gave him a number. He said, “That’s it?” She said, “Yes.” He wrote her a check on the spot, standing on the gravel access road with the creek running under the new beam behind them, and he said, “I’m going to need your number for the next job.
” She gave him a business card from the front pocket of her work shirt. It had her name, her phone number, and the name of her company, which was Marsh Heavy Rigging, and nothing else.
Curtis Yellen drove out to her property in Mossback 3 days later. He sat at her kitchen table and drank a cup of coffee and did not say much for the first 15 minutes, which was his way.
Then he said, “Your daddy would have liked watching that.” She did not answer right away. She was looking out the kitchen window at the shop where the Euclid was parked with the shop doors open.
Then she said, “He taught me how to read a load chart.” Curtis nodded. He finished his coffee and put the cup in the sink and drove home. She had set four bridge beams since Cutter Creek, two for the county road crew, one for a private contractor in Morgan
County, one for a state highway project in Cumberland County, where the state’s equipment was unavailable due to a scheduling conflict and a project engineer who had heard about Cutter Creek through the kind of network that runs on co-op bulletin boards and parking lot conversations and phone calls from people like Curtis Yellen.
On each of those jobs, the Euclid has done what it did on the morning of September the 27th, 2022. It has spread its weight across the ground and held. It has lifted clean and set clean, and the bearing plates have been right the first time.
The machine has not been repainted since Della finished it in 2016. The yellow has faded again back toward the color of old mustard, and there’s a new rust bloom on the left side of the cab where a piece of debris struck it during the Morgan County job.
She has not painted over it. She was asked once by a journalist from a regional trade publication who was writing about the Cutter Creek job whether she had ever considered upgrading to modern equipment.
She thought about the question for a moment, then she said, “The R-27 knows what it’s doing. I know what it’s doing. That’s not something you replace.” The journalist wrote that down.
Then he asked if she had any plans to expand the business. She said, “I have plans to keep doing the work correctly.” He wrote that down, too. And when the article ran, that was the line they used as the headline.
The Komatsu PC800 is back in the rental fleet. It is a fine machine on the right ground. The ground at Cutter Creek was not the right ground, and no amount of money spent on a machine changes what the ground underneath it is willing to hold.
Della Marsh understood that before she drove 41 miles on a Tuesday morning in September. She understood it because she had spent 14 months rebuilding a 63-year-old machine and reading the engineering documentation and learning what the engineers in 1959 had already worked out about the relationship between weight and ground and load and patience.
The knowledge was there. It had been there for 60 years. It was waiting for someone who was willing to go find it. The Euclid is in the shop right now, as of this telling.
She is doing the annual inspection, checking the hydraulic pump clearances, measuring the boom cylinder bores, going through the final drives. The engine turns over on the first compression cycle every time she starts it.
It has done this since the spring of 2016. She expects it will continue.
