Pillar load-bearing or not

[d_sandstr_m]

I have a garage measuring 10x6 meters built at the end of the 1950s, the roof is a poured concrete roof with a metal roof on top. In the middle of the garage, I have two columns with a small beam between them, the question is whether it is load-bearing or if it was used to lift things, what do you think?

My amateur eye says that the columns are very load-bearing

It appears that they were added afterwards, the material on the pillars is probably only 3 mm so they don't feel very sturdy when you knock on them, shouldn't a cast ceiling of 13-14 cm be self-supporting?

Of course, it is load-bearing; otherwise, it would never have been put there.
The question is what it supports. My guess is that it is for hoists/hoists, to lift cars and/or car parts.

Feels like a lifting device, like a hoist, as fahlis says. However, it looks like the joist is bending down a bit if you look at the shadow over the beam (assuming the beam is straight), so the previous owner might have put the beam there to 'prop' up against the sagging.
