A newly installed overhead drum machine...
Please note the disconnect at the top right of the machine which is probably the "machine final limit."
There is a connection between the machine and the handle...if the car overtravels the disconnect is opened.
Most authorities require a "machine final limit." (See A17.1S-2005 - 2.25.3.3.2 in the U.S.A.)
Please note the manner in which the ropes wind on and off the face of the drum.

Tennessee Coal & Iron's Ensley Works - Birmingham, Alabama, U.S.A.
I would guess that the chain running from the drum shaft to the controller is used to
operate the "machine final limits" as required by most codes. (See A17.1S-2005 - 2.25.3.3.2)
Most jurisdictions do not allow the use of "chains, ropes, or belts" as a driving means for these devices.
More of these microdrive machines are located here...
