Time flies! Clock face falls from crane, strikes two workers - No injuries?

Time flies! Clock face falls from crane, strikes two workers - No injuries?

RE: Time flies! Clock face falls from crane, strikes two workers - No injuries?

haha, Boiler up.

Saw that earlier today, didnt think to put it here.

There was a second photo on reddit yesterday showing pretty severely sun-bleached clock hands. I imagine that they were doing maintenance.

RE: Time flies! Clock face falls from crane, strikes two workers - No injuries?

Well, Purdue has had it's clock cleaned several times this year.

This is no surprise.

"The Clock struck two"

RE: Time flies! Clock face falls from crane, strikes two workers - No injuries?

Here's the culprit.

RE: Time flies! Clock face falls from crane, strikes two workers - No injuries?

I cringe when I see vids of rigging failures (no matter if small loads)

the other safety observation besides the loss of the load was the workers were under the load when it fail.

this is the old face from reddit. can't make out how the face is attached to the cable.

RE: Time flies! Clock face falls from crane, strikes two workers - No injuries?

That clock face is so similar to the "Back To The Future" clock it's amazing.

RE: Time flies! Clock face falls from crane, strikes two workers - No injuries?

I guess they were sad when their face fell.

"Her face has fallen arches. It hangs just like a sack. She'd like to have it lifted, but she doesn't have the jack."- Homer and Jethro.

Come to think of it, I've heard that song since I was a kid, and never dawned on me that jack is slang for money, so a good pun was wasted on me there.

RE: Time flies! Clock face falls from crane, strikes two workers - No injuries?

Maybe I'm acutely aware of any movement when I'm on an aeriel lift, but I'm surprised how little that thing moved when the clock face hit it. I was on 100' articulating lift a few weeks ago and I felt like it would move 1-2' everytime we boomed to a new spot.

RE: Time flies! Clock face falls from crane, strikes two workers - No injuries?

I'm not surprised when anything happens to that clock tower. The tower has fallen over in heavy winds twice already, this is the third tower and its had so many other issues over the years it has started its own myth - "walk under the clock tower and you wont graduate." Rather ironic to see such a thing at the central landmark of an engineering school.

RE: Time flies! Clock face falls from crane, strikes two workers - No injuries?

I just watched the video and feel guilty now for making light (above) of the situation for the two workers. It took me several times viewing (projected on my large television screen) to finally comprehend that there was that bucket lift with some workers on it, below the lifting crane. You can see their platform (them?) get struck by the clock face. Hopefully they are okay.

The sensation of realization was a bit like when I watched live news videos of the 1988 earthquake in San Francisco and realized that what I was seeing was double-deck highways that had collapsed. ...then realizing the cost in human lives could be very high; fortunately there were not many fatalities (any?) in that event.

RE: Time flies! Clock face falls from crane, strikes two workers - No injuries?

The article said there were no injuries.

CWB1,

Thats not quite correct. The first tower, which was built in a different part of the campus as a part of Heavilon hall. It burned down 4 days after completion of construction in 1894. The university raised funds to build a new building "one brick higher" (which is used in marketing even now for the university). The 2nd tower, seen below, lasted from 1895 to 1954. The 1954 building was demolished and replaced with a building of the same name (that exists today). There was no bell tower on the Purdue Campus until 1995. The belltower in the video was constructed in 1995, but the bells themselves (which are not really functional) are from the 1894 bell tower. The current iteration for the tower utilize electronic clappers for the chimes.

I graduated Purdue in 2008 and we actually did "wind calcs" as a practice problem on that belltower. I'm sure I did it wrong at the time, but it was a sort of interesting homework problem. I also used to (and still do) have a thing for the architecture and history of university buildings, including Purdue.

RE: Time flies! Clock face falls from crane, strikes two workers - No injuries?

CWB1, ever since they took the old one down the new versions have been designed by architects not engineers.

RE: Time flies! Clock face falls from crane, strikes two workers - No injuries?

On my school's campus, Michigan Technological University, we also had some great looking old buildings that eventually fell to the wrecking ball. The first building of what was then known the Michigan Mining School was constructed in 1889:



The image below was taken just before they demolished the building. The modern high-rise to the right was the new Chem-Bio building, which basically replaced Hubbell Hall, on the left. I had only one class in the building my freshman year (1965/66), a chemistry lab, on one of the upper floors where the walls had cracks in them so large you could see the outdoors and the cold wind would blow thru (the school is located in Michigan's Upper Peninsula near the shores of Lake Superior).


September 1968 (Minolta SR-1)

Less than a month later, they had pretty much taken the building down.


September 1968 (Minolta SR-1)

While we never had an actual bell tower on campus, when they opened the new Library building in 1966, it included a modern electronic carillon which chimed the hours as well as being available for being played using an organ/piano-like keyboard located in the Library building.

I had to inspect this metal grain bin that had reportedly been damaged by wind while it was being lifted off its foundation for relocation. Upon closer inspection it became evident that they had lifted the entire structure by straps looped through the internal wind rings--all light gauge metal and a few screws--and the bin had just pulled free and dropped to the ground.

"CWB1, ever since they took the old one down the new versions have been designed by architects not engineers."

As with most architectural structures, the architectural design (shape, size, features, finish, etc.) was likely done by an architect. The structural design, by law, would be the responsibility of the licensed engineer whose seal and signature are on the structural plans. Engineers are allowed to do architectural design, but architects are not allowed to do structural design, unless they happen to be a licensed engineer also.

...but architects are not allowed to do structural design, unless they happen to be a licensed engineer also.

I don't think that is true in Florida. There is parity in the language of both regulations that one is allowed to do "incidental" work in the other.

I think the judges have basically ruled that one is the same as the other where expertise can be demonstrated. Granted it might be a rare architectural bird that can do the structural design for a 3-story clock tower. There might also be restrictions for threshold buildings but I don't know where that language is.

RE: Time flies! Clock face falls from crane, strikes two workers - No injuries?

In WA, Architects can do minor structural design if they are comfortable with doing that, but most don't. Primarily simple beams and footings. No lateral.

RE: Time flies! Clock face falls from crane, strikes two workers - No injuries?

Boilermaker from '03, myself (though I didn't see campus after '00 until I flew back to defend)... we hid the clock tower behind all of the engineering buildings (we put it close to the school of music winky smile ).

RE: Time flies! Clock face falls from crane, strikes two workers - No injuries?

RickyTicky, I don't recall details but have been told several times that some iteration of the tower did blow over unexpectedly in explanation of a picture, I believe in the underground commons/library, of the aftermath. Maybe it was during demolition of one?

I lectured and took a few classes at Purdue but never pursued a degree there. My wife's second degree is from Purdue however, but she's probably one of the few people less interested in school trivia than I am.

RE: Time flies! Clock face falls from crane, strikes two workers - No injuries?

I believe that if you look closer at the regulations, you'll likely find that they will preclude anyone who is not licensed from doing any actual structural engineering where lives would be at risk if it were to fail. Perhaps others are allowed to 'engineer' some non-critical 'structural components', or choose beams from a span table, but I'd be surprised (and quite nervous) if states were allowing those without a PE to do actual structural design on anything of consequence.

RE: Time flies! Clock face falls from crane, strikes two workers - No injuries?

John:

Your picture of the old stone building at Michigan Tech reminded me of the history of the "Old Chemistry" building at Stanford. It was originally built in the 1890s:



It was badly damaged in the 1906 SF earthquake:



After repair, it was used again until the 1989 Loma Prieta quake. Then it stood empty for about 25 years while they tried to raise the money to bring it to modern seismic standards (plus ADA-compliance, energy efficiency, etc.) Finally it re-opened about a year ago. The exterior stonework is now really a cosmetic shell, with a steel framework inside providing the actual structure. I'm sure it would have been much cheaper to tear it down and replace it with a new building.



Hey, what happened to all the chimneys?

RE: Time flies! Clock face falls from crane, strikes two workers - No injuries?

One thing at Michigan Tech, we had almost NO chimneys on any of the buildings on campus. That's because years ago they had built a central steam heating plant down next to the lake, where they had easy access to coal, which was also being shipped in, by lake freighters, for the copper mills which were built along the lake shore. Years later the plant was converted to oil and who knows, maybe it's using natural gas by now. They used to hold labs down at the power plant for things like steam-based applications, including running a couple of different steam engines, and real-world studies of heat transfer (not sure if those classes are still being held there, but they were back in the 60's and 70's).

Now this campus-wide system even provided heat and hot water for the student apartments where my wife and I lived the last three years of my time there.

Here's a recent shot showing about half the campus from above Portage Lake. The red building on the Right, near of the water, that's the central steam plant. As you can see the only visible smoke/steam anywhere on campus is coming only from those buildings.

They replaced the faces. Didnt fall.
