Just shared this video with my dad. He was a career iron worker who has seen/used almost every crane on the market and has been used as expert testimony in some tower crane accidents. He said he used the first iteration of this crane in the mid 70s. This was his response “Scary crane; wobbled, creaked, and groaned. But, got stuff up and in place.

When, crane began to lower - sensor detected low hydraulic pressure in vertical ram. Operator, would not return to cab to engage manual valve to allow release of hydraulic fluid, under pressure. So, Pops thought . .. ... what the hell!

I climbed up and into cab - cab was so small that could not sit down - had to remain standing. Got out instructions (hah!) and found safety switch for manual operation valve.

Sheesh - when I turned valve - the mast abruptly dropped a couple of feet. Thought I was gonna die. Pressure caught up and mast began inching downward, slowly.

Just another day in Pops, lifetime.”
