Workshop gantry crane

I tried to enlarge the pic but it's not clear enough to see the welds close up - they look a bit 'blobby' but could be strong enough in actuality?

I lifted an 800 kg generator set, it should hold about 2 tons, I didn't immediately post the photos as I had so many difficulties when I opened the discussion of the trusses I saw that I had left the message unfinished and I inserted the photo, thank you very much everything, if you think it should be strengthened or modified I am happy to follow your suggestions thanks again for your precious suggestions and your kind availability greetings
