Old conventionals at work

Heavy timber has its own type of fire rating. Heavy timber is a minimum of 8" x 8". The outside wood chars and protects the interior of the beam. In the old construction where cast iron was used for connections, in a fire the cast iron will fail before the timber.

None of the wood used for the roof looks to be large enough to be classed as heavy timber.

They used to say that a wood king beam in a house would take more heat than a steel beam. The steel will bend under the heat and fail, before a wood beam burns through.

Those beams might survive a fire, but the TGI purlins they're hanging between them go up like a popcorn fart. I've seen them burn and they went hot and fast in a fire.

Nice crane work Ryan, I love seeing the old girl out working.

I recall in my mis-spent youth demolishing a building that had been the workshops for a coal mine in the town I grew up in. Somewhere about 300’ long x 60’ wide. All the equipment in the shop was powered by a single shaft running along the roof trusses. IIRC the trusses were 18”x12” pitch pine with cast-iron caps in the corners and on the hip of the roof that were all held together with wrought-iron rods. The building dated from the late 1870’s when the colliery was first opened. It’s centre left on the sepia-toned photo in the link below.

You're not wrong. I investigated my family tree a few years ago and back somewhere in the 1880's a relative of mine had been wed & widowed twice by the age of 30. Both her late husbands were listed as miners at the time of the wedding. She was left to bring up four children as a single mother.

Looking more closely it was actually my great-grandmother on my mother's side. Coal mining ran in that side of the family right down to my mother's brother and his son. Both did over 40 years underground and survived to tell the tale.

I had to find these photos. The lowboy & shovel parked right in front of said building. Probably late 1950s or early 1960s.




Apologies for hijacking Ryan's thread...........

Its ok it was worth it for the picture of that shovel. Nice to see them when they were a respected piece of iron.

Steam power was a great leap forward as a power source.
We need to start a movement to outlaw Diesel/Electric locomotives.
Only Steam allowed. 4-6-6-4 or larger allowed

We had three of them as I recall, and had face shovel and crane equipment for all of them. Here's the same machine building prefabricated housing just after WWII, probably early 50's. This was housing built to replace what the Luftwaffe flattened during the war. One of my cousin's lived in a similar housing development, known locally as "Concrete Canyon".

This is where the shovel in post #428 was heading. In fact that's probably it in the centre of the photo.

Looks like the weather is cooperating

Cannot remember seeing Vacuum Breakers on Spuds before, someone got ingenious. Site demo or moving it?

 

[Tugger2]

Weather was great ,once we started. Moved the crane in on the weekend. Went back early Mon am to rig up,it was snowing slush.Nothing like crawling around the machine jacking the tracks out with slush running down the back of your neck.The sun came out around mid day and stayed until Sunday am when i had to jack the tracks back in ,guess what more slush /snow. Job went well, Lima is back in the yard for a breather and a few repairs .
As to the vaccum breakers ,we arent that ingeneous, just what came with the former fuel barge we had rented. It was another site demo , more industrial infrastructure taken from our fading forest industry.
The log booms in the background are destined for export and now i hear theres plywood sold here thats stamped made in china. Ill cut my 2X4 s with a friggin broad axe before i buy one from overseas
