Forum member SkyJacked has captured an awesome shot for us to enjoy today. Up close and personal with an "A-frame sheave block." That's shop-talk for a particular component of a crane, in this case the one atop L Tower. Juxtaposed against the city below, and in commanding bright red, it makes for a dynamic image. And gives us regular folks a chance to see some of the amazing machinery used to build all the towers that surround us.
