Maybe post a picture that includes the entire bottom of the projector so people can actually see the mount attached to the projector ? Showing JUST the hooks makes it difficult to conceptualize the entire mount...
Pretty much any/all projectors use hooks attached to the bottom of the pj, and a metal box with short protruding rods that attaches to the ceiling. The idea is you attach the metal box to the ceiling, then simply hoist the projector up and hook the hooks on the stubs of metal rod sticking out the sides.
The top picture shows a Marquee factory mount, two hooks for the bottom of the projector and the box which is attached to the celing.
The bottom picture shows an NEC factory mount, the two hooks are hooked onto the box in this picture, the projector would attach to the flat parts of the hooks which are facing up in the picture.
Barco's are the only projector I know of which do not use this basic mount system. On a Barco there are metal pieces which attach to the bottom which face one another like this [ ] . Each metal channel is at the extreme end of the projector, one front, one back. An easy way to mount a Barco is to place two pieces of angle iron on the ceiling like this ] [ the correct distance apart, then simply slide the projector onto them. [][] Like that, but offset so the flat parts of each piece of metal rest on one another, of course...
This is how I've mounted my Marquee, it allows for easy adjustment forward/back and side to side, yet is very stable and won't move around when you set your focus, toe in and scheimpfluge.

I love that iron bar set-up great ingenuity. That takes out all of the "I got to be dead on with this measuring." Cool.

That looks to me like the projector side of a mount, like one I have in my garage. I was told by the guy who gave it to me it was a "Monger" mount. They are an aftermarket maker of mounts...or were, I don't know if they still exist...

My ceiling mounted Marquee is done very, very simply. While I DO have the LOWER half of the factory pulley-equipped Electrohome
Marquee bracket, I've done essentially this same simple install on other Marquees, WITHOUT ANY FORM OF BRACKET.
The corner holes in the Marquee base have 3/8-16 threaded inserts in them. This is a standard thread for threaded rod and hardware
you can get at any hardware store.
I drilled two holes in two 2x4s. They're spaced to match the spacing of the mounting plate holes.
I screwed eye bolts into the base of the Marquee, and ran threaded rod down through the 2x4s, from up in the attic, through properly
located holes in the ceiling, and used threaded couplers to connect steel hooks to the threaded rods. Two strong men to lift, from a
suitable height platform, and a third to guide, can take the PJ down or install it in about 20 seconds. Extra nuts are on the hardware
to use as jam nuts. This system is simple and fully adjustable for height and tilt angle. It'll cost you a few bucks total.
Cut down to the essentials, it's eye bolts and hooks and the threaded inserts in the Marquee base. Easy to figure out.
On my own machine I used the bracket and pulleys as half of a home-built hoist system. I can take down and lift and install my 9500
all by myself. I've done it. With a 4:1 mechanical advantage, I can easily handle the 50 pounds of pull required to hoist up the 200
pound projector. All hoisting and lowering is done with me inside the attic. Tie off the rope, very securely, go downstairs, set the
bolts and nuts, go back to the attic and finish the lift, go back down and complete the mounting adjustments.
