You really need the circuit diagram to be sure.

My limited experience of more modern car lifts suggests that the control design isn’t as simple as it might seem at first. Rather different to the relatively crude systems up’n down button devices used on old style Bradbury’s et al.

I used an Eaton DE1 “intelligent starter”, basically a VFD without all the external control bells and whistles, to convert my 3 phase lift to run off single phase. Although mine appeared to be variant on the “semi-standard” import lifts available in both three phase and single phase form I’m pretty certain that the control board couldn’t be simply re-configured from three phase to single phase. As I recall things it appeared to be a common board for both single / three phase and pneumatic / electric safety latching switching from one to the other would have needed on board component changes.

Getting on for 8 years ago since I put it in so my memory might not be correct. It’s quite possible that I misunderstood the system.

YMMD

Personally I’d want to be very sure that all is working as per design when I’m under the car. Had some interesting issues with the safety latching system on the one a friend installed due primarily to it having been installed improperly at the previous owners place. Replicating the installation in my friends workshop didn’t give the warm, fuzzy feeling of safety.
