It’s important to note that Chell has reinforced legs. That is important for the whole weight distribution thing. She can probably lift heavier things or at least become less fatigued carrying something for long periods of time.
She doesn’t have reinforced arms and is able to aim it precisely over those same periods. I do like the idea that heavy components e.g. massive amount of power are connected to it remotely via the portal tech itself, but what we see of it on this side that’s in Chell’s hands is definitely lightweight.
