Thunder Crane TC20 stiffleg derrick crane
A derrick is a lifting device composed at minimum of one guyed mast, as in a gin pole, which may be articulated over a load by adjusting its guys. Most derricks have at least two components, either a guyed mast or self-supporting tower, and a boom hinged at its base to provide articulation, as in a stiffleg derrick. The most basic type of derrick is controlled by three or four lines connected to the top of the mast, which allow it to both move laterally and cant up and down. To lift a load, a separate line runs up and over the mast with a hook on its free end, as with a crane.
A stiffleg derrick, also known as a Scotch derrick, is a derrick with a boom similar to that of a guy derrick, but instead of using guy wires to secure the top of the mast, it uses two or more stiff members, called stifflegs, which are capable of resisting either tensile or compressive forces.

It has not collapsed yet. Democrats are electing a new chair RIGHT NOW (I don't know the date, but in the next few weeks).
They are going to elect a centrist. We can stop them. Now is the time.
If the new DNC is progressive and inspires people, it will prevent reluctant Republicans from going full scorched earth.
A progressive platform will win Democrats the white house for the next 20 years. Ask FDR how I know.
This, right now, is the final chance we have to prevent collapse.
Spread the word, share & cross post.
