My good friend Jeff Mann, the true Yard Ramp Guy, has asked me to revisit some of my original contributions. And so: my From the Archives series. This week: Italy makes me dizzy.
There is one kind of ramp I absolutely love, except when I'm using it, in which case I absolutely hate it. That ramp is the switchback.
Anyone who's done much mountain driving learns to hate switchbacks, even though they're some of the most cost-effective engineering tricks we have in the mountains. (Much, much cheaper than tunnels, that's for sure.) Truckers especially hate them. I've known some who will go hours out of their way to avoid them. I think gearheads are the only ones who enjoy them.
One of the craziest examples of the breed is the Stelvio Pass in Italy. It's one of the highest roads in the Alps and has 75 switchbacks. Seventy-five! Not a road you want to drive fast on, or even drive on at all if you can help it. Apparently, it’s so dangerous during the winter and spring that they close it completely during those seasons.
Of course, being dangerous, gearheads flock to it. That British car show everyone likes, “Top Gear” (I don't watch that show anymore after what they said about the F150), declared it the greatest driving road in the world. (Or at least in Europe. Have you seen the pictures of the crazy roads they have in the mountains in India?)
The Italian bicycle Grand Tour frequently goes through Stelvio Pass. (The Giro d'Italia, sister race to the Tour de France. I try to catch all three of the Grand Tours when I can.) Thousands and thousands of cyclists ride through Stelvio Pass every year.
It's easier to find info on battles fought at the pass than it is to find anything beyond basic info on its construction or maintenance, but that's pretty constant. Historians are obsessed with wars, despite the fact that construction and architecture affect us way more.
I'm working on persuading Maggie on this European vacation bit but, as carsick as she gets, I don't think that Stelvio Pass will be on the itinerary.
The Yard Ramp Guy Blog: Moving Your Yard Ramp
This week, my friend The Yard Ramp Guy provides some astounding weight comparisons (and gives me newfound respect for the blue whale, from which I'll never ever wish to receive a tongue lashing), then transitions from heavy to smooth and shows how easy it is to move a yard ramp.
Buckle up, then click HERE to read all about it.
My good friend Jeff Mann, the true Yard Ramp Guy, has asked me to revisit some of my original contributions. And so: my From the Archives series. This week: ancient Greeks multitasked in a most remarkable way.
Most of the historical ramps I research are generally of a pretty temporary nature: pyramid construction ramps, siege ramps, etc. They're built for a single purpose and then abandoned or destroyed. They're machines, and they don't have a long-term purpose.
I have found a few ramps that are different, though, and one of my favorites is the Diolkos.
The Diolkos, built by the ancient Greeks, was half ramp, half causeway. It was used to transport ships across the Ithmus of Corinth, saving them a dangerous sea voyage. The ancient Greeks actually dragged the ships overland on it. (You'd think a canal would be easier to use, but canals are a lot harder to build and maintain.) Huge teams of men and oxen would have pulled the boats and cargo across it in about three hours per trip.
No one is quite sure when the thing was built, but at best estimate it was in use from 600 BC to 100 AD, which is a pretty good lifespan for a project like that. It was mostly used for shipping but also served a pretty vital role for navies during war.
There isn't nearly as much information on the Diolkos as I would like out there. The ancient Greeks mostly wrote about their gods and heroes and wars and such, which is disappointing but not unexpected. Most people want entertainment; they're not looking to find out how the world works.
Today the site has been destroyed in parts by the Corinth Canal, and much of the excavated portions are falling apart due to lack of maintenance and boat traffic on the Canal. It's not exactly the Parthenon, but it represents a vital look at how the day-to-day functioning of an ancient society actually worked.
Maybe I can convince Maggie that we should go to Greece next vacation.
The Yard Ramp Guy: Ramps Rusting Gracefully
This week, my friend The Yard Ramp Guy pivots from writing about steel as the literal foundation of his business to take on the benefits and drawbacks of new technology. Of course, I always appreciate a cautionary tale.

My good friend Jeff Mann, the true Yard Ramp Guy, has asked me to revisit some of my original contributions. And so: my From the Archives series. This week I'm under siege. By medieval ramp monsters.
I know I've kinda built up the idea about myself that I don't care about medieval warfare, that I consider it an absurd waste of thought. And, well, generally speaking, you'd be right. I think it's a distraction from the things that actually matter, like actual historical construction methods. I'm interested in how they put things together, not how they broke them.
That being said, some slightly interesting uses were found for ramps in war, specifically for the purposes of siegecraft.
The first use was actually pre-medieval, though it was used on occasion in medieval times. Siege ramps are huge earthen ramps built right up a castle or city wall, a cliff face, or other positions of strength. They're about as absurd as you'd think: the builders are going to come under constant attack by the people above, resulting in a wasteful loss of life. It was really only used when the besiegers grossly outnumbered the besieged, were otherwise unable to break through the enemy defenses, and had little care for loss of life on their side. The Romans used it a few times, as did a few of the smaller empires before them, and a few of the smaller kingdoms they conquered.
The other use was in siege towers. These, at least, were constructed with a bit more safety in mind for the troops on your side: not that sending them over an enemy castle wall is, particularly, a safer idea. Siege towers, depending on the whim of the builder, were generally a bizarre hybrid of ramp, staircase, ladder, and watchtower, all built out of wood and canvas and stuck on wheels to roll right up to the castle walls, where troops could exit the tower directly onto those walls.
They also usually had sheltered positions for archers to fire from. Still absurdly dangerous, of course, but you at least had some shelter from enemy arrows, at least until you got onto the wall. They still were vulnerable to fire, which medieval people loved to use on each other.
All in all: I prefer my ramps for actual construction purposes.
The Yard Ramp Guy's Continuing Education
This week, my friend The Yard Ramp Guy begins with a proverb about the stars and a finger. Which is right up my telescope alley. And he ends with an invitation to give him a call. And it all has to do, wonderfully, with the way he conducts business.
Before you give him a call, have a gander at his words HERE.
My good friend Jeff Mann, the true Yard Ramp Guy, has asked me to revisit some of my original contributions. And so: my From the Archives series. This week I explore the earliest civilizations that built with⏤ surprise ⏤ ramps.
Information on the Internet about the construction of the great cities and monuments of the Mesoamerican and South American cultures is surprisingly hard to find, it turns out.
The Aztecs were real tricky to find stuff on. Almost every supposed "source" detailing its construction techniques immediately starts going on about how they sacrificed people during construction, then doesn't bother to actually discuss the techniques they used. I'm no trained historian, but that seems like sensationalism to me, and it sure doesn't answer my questions.
There are a few interesting tidbits out there, though. Teotihuacan, one of the major Aztec sites, was actually constructed over a thousand years before the Aztecs gained power, by someone else entirely.
The Inca and Mayan empires have a bit more out there to easily find. I had to dig through a lot of nonsense about Mayan prophecies and their mass disappearance, but there was a lot of good stuff. Like this: They actually used a primitive form of limestone-based concrete for much of their construction.
The Incans were the easiest to find information on, since most of the stuff on the Internet is about their construction techniques anyhow. Their buildings were famed for being constructed of huge stone blocks in irregular patterns that for together perfectly, without gaps. You can't even stick a knife between the stones.
People go crazy over that, some even going so far as to say that there were aliens helping the Incans. (Some nuts out there.) I think it says more about contractors today than it does about ancient construction. Tight seams just take good workmanship.
The stones in Incan constructions were placed by dragging them up huge earthen ramps on log rollers. Interestingly enough, they took the opposite approach to the ramps than the Egyptians, who just put together giant straight ramps. The reason they could do that when the Egyptians couldn't is pretty simple: the Incan Empire was huge. It was basically the Rome of South America. It could afford to just throw manpower at problems until they were solved.
They did save a little money by using locally quarried limestone or granite, but the empire was wealthy and powerful enough that it could have shipped them halfway across Peru on their excellent system of roads if the whim overtook them. We have tons of archaeological evidence for the Incan ramps, and a few—even still—partially exist.
