Dinosaurs

Once we had a trailer load of panels in our storage space next to the building, we would inspect them to see if they needed any repairs after their journey across Donner Pass. And we always had some damage. The most irritating damage was having the panels ‘smoked’. The owner of the building had decided on a white synthetic plaster finish and all it took to ruin the looks of them was diesel exhaust blowing across the panel surface for 100 miles or more. A poorly tuned diesel at that. The first truckload was delivered without being tarped and they had large black streaks on them, plus some additional damage from the binders that held them in place. I had to insist on tarps from then on, but that persistent smoke could still find its way onto the load; turning the outer panels a light gray in color.

After the repairs were complete, we had to find a way to move the huge panels from the trailer and over to a spot on the ground below where they were to be installed. We had a large forklift and some portable stop signs and we would try and halt traffic just long enough to move down L Street and place the panel, resting upright, against the building. Halting traffic without a permit was frowned upon by the authorities and getting a permit each time we needed 5 minutes of hauling time was more trouble than it was worth.

Up on the 6th floor were our hoisting machines. Nicknamed ‘dinosaurs’, they had a short boom section coupled to a 220 volt 2 phase motor and some reduction gears that would allow it to hoist about 3,000 pounds. Each ‘dinosaur’ had wheels and counterweights to allow for heavy lifting. Plus, a section of pipe that we would raise to the deck above us, clamping the ‘dinosaur’ in place.

And since the ‘dinosaur’ couldn’t always be directly above the panel to be lifted, we used ‘snatch blocks’ to reroute the hoisting cable to a spot where it would work best. It was all improvisation and sometimes the cable was running at 45° to the ground and then back again, depending on what kind of obstructions we had to deal with. No one had ever done this before and so every time we successfully lifted a panel and welded it in place, I breathed a sigh of relief.

I almost forgot to mention the trees; the City of Sacramento was quite proud of it’s designation as a Tree City and the building permit stipulated that NO tree was to be removed or damaged during the construction of the building. Unfortunately, some existing trees were growing right over the building. This meant that sometimes we had to arrive on the jobsite at 6 in the morning while it was still dark. When the sun rose at 7, the offending branch was usually gone and the dumpster was full and covered.
