First is a PLC.
Probably worth money to somebody who needs that exact model, however it's the kind of thing that can sit for years unsold on various sites, being sold by those who are happy for it to sit on their shelf in the hope they find that magical buyer who is desperate for that exact module, and will pay lots of money for it.

Second looks like a drawbar puller.
Again, if you knew the machine it's for, you might get some money for it, as it probably costs 3 or 4 figures new, but again you'd need that magical buyer who needs that exact part, and is willing to use a part from an unknown source.
