Mundane pointless stuff I want to ask: use for a helepolis?

Can you think of a modern, peaceful use for a helepolis? I spelled that right. The Ten Biggest Land Vehicles Ever Built

It’s the only man-powered vehicle that made it to the top-ten biggest land vehicles ever built. It’s a mobile siege tower 65 feet wide, 130 feet tall, with at least eight levels, mounted on eight wheels, and requires 3,400 men to push forward.

I can think of a mobile office building, but forget the 3,400 man-motors. Just use a couple of rhino rigs to tow it. “Ok folks, our lease contract with the lot owner expires next week. We’re moving over to the Wal Mart parking lot across the street. Strap down your things…”

Convert the upper floors to luxury boxes and roll it up and down Sheffield Avenue while the Cubbies are playing.

The mining industry has a mobile hoisting house than can be moved from one mine shaft to another, depending on the need.
