The governor...looks like a friction type
Please note the contacts above the roller arm. The roller rides on the lobes of the
governor rope sheave and bounces higher as the car/governor speed increases.

The data plate for the low (slow) speed motor...
250 U/min = 250/RPM
This elevator has a 6:1 speed reduction
The rated speed is 0.63 m/s (124 FPM) so the
leveling speed would be about 0.11 m/s (21 FPM).
Please note the frequency is listed as 50 hz.
At 60 hz we might see a rated speed of 0.76 m/s (150 FPM)
with a leveling speed of 0.13 m/s (25 FPM)

Image 19
It appears that the vertical bar is treaded and travels horizontally between the cam stops.
If the car travels past either terminal landing the cam stop will engage the bar and
turn the mechanism which will open contacts in series with the 'mainline circuit.'
