My understanding is that if installed for their intended purpose with the circular plate being used to set the declination offset angle they are for prime focus dishes. The declination offset angle is set by rotating the circular plate and for an offset focus dish this would result in the dish being rotated so that the long height of the dish was no longer vertical.
If I get around to refurbishing the unit I have, I will either modify or replace the circular plate with something that allows setting of the declination offset angle using a threaded bolt or stud. The modification I have in mind should also allow the motor to be used with offset dishes.
I think that the motor is of a more robust build than a Jaeger 1224. It was an earlier design by SuperJack that was later followed by the SMO-36 and the Jaeger 1224. The pole cap and motor casing are steel rather than alloy and it looks up to moving a reasonable size dish. If a beefed up Jaeger 1224 can manage with a CM 1.8m I would guess the AHM-36RL is capable of handling one?
