[TABLE="width: 100%"]

[TD="class: info_text"]Hi!
A bit of a dumb carpenter question, but I'm not a construction expert in that material either;
I am in the process of building a workbench at the back of the house. The idea is that I will be crafting and working on various projects on the table (sanding, sawing, welding, etc.). The table should also be able to carry a load of 200-300 kg - this is because from the intended tabletop you should be able to stand and place things on the adjacent storage roof which in turn leads to the house's crawl space.
I have placed four pillars with posts (95x95) in the ground which will, so to speak, become the table legs. The length and width between the posts are about 200x70 cm. The tabletop will consist of a fixed crosspiece over each pair of posts and longitudinal coarse planks that should be about 50 mm thick.
Now the actual question; how do I most easily and effectively attach stabilizing joists to the posts on the short and long sides?
At first, I thought about putting a 95x137 beam hanger on each post side with a joist inside - but maybe that's not optimal.
If there are any tips or even warnings I would be grateful.
Since I will be standing on the table myself with a load in my hands and there is stone paving underneath, it is highly important that the contraption becomes über-stable

To achieve maximum stability, you should place the beams under the tabletop on edge along the two-meter side and then lay the 50mm planks across the table on the beams. There will be a slight flex even in a 50mm plank over 2 meters if it lies flat, but almost none if it stands on edge.
Your idea of using a beam shoe will work. Diagonal braces from the bottom of the pillars to one meter in on the beam under the tabletop are even more stable than a beam parallel to the tabletop. Also, put a cross between the pillars at the end of the table. The advantage of a beam shoe is that you can easily have a shelf under the table.
Comparison. I have built 9-meter high scaffolding from thinner wood than your table.

Doesn't it seem risky to weld in such a completely wood-dominated environment?
And with the timber storage right above as well.

@brumbjorn; many thanks for the feedback. I might have to consider whether it is better to use braces instead of horizontal joists in beam hangers. What I like about the latter option is, just as you mentioned - you can make shelves with this solution.
No, not a tank- but I am quite heavy myself, plus some load-bearing in my arms and a few things placed on the table before stepping up to the next roof - then I would like to be "fully insured" in the construction.
@KnockOnWood; it is probably not entirely optimal - but the environment is reasonably safe, I think; the table stands on a paving stone, next to a 2.5 m high asbestos wall that transitions into a high metal edge framing the roof of the adjacent shed. From this flat roof, you then have to walk another five meters to reach the attic.
Thanks for the feedback and continued pleasant summer / Jörgen
