Unusual device

Today, on the eve of the next visit of firefighters in my faculty (biology department, if it is important) began unplanned garbage collection and various old equipment. Therefore, on the top floor, in the farthest corner of the box was found, with a strange device. None of those present, including the deputy dean, department head and dean himself, could not identify him, and even more so for what this unit can serve. Request to know a lot about the people - tell me what it is?
Will be 13 photos.
Here in this box, this machine is.
