We had one in our imprinted concrete and tried everything, apart from one of those lift dollies (that I have never seen before). I ended up cutting it out with an angle grinder and replacing it with a similarly cloured/patterned flagstone and a rubber seal, over the top of the inspection hatch.As I have said, we have yet to lift one successfully without removing the material from inside the lid.

If the frame is moving, I keep the manhole cover under strain and tap the edge of the frame with a bolster. The cover normally pop right out.

A ground worker back in the day told me to add sharp sand to the grease to give it some body to stop this. I'm not sure if it works as I've never been back to all those manholes I was privileged to build when fresh out of college.
Plumbest, squarest, best bonded and weather struck manholes in the world though. Shame to put the lids on.
My knee still suffers to this day (as a 20yr old)whereby I dropped my full weight on it on the corner of a manhole having slipped whilst exiting it, having dome some exquisite benching. I even had a cut down pointing trowel just for that job.A ground worker back in the day told me to add sharp sand to the grease to give it some body to stop this.
