Meaning of スチーム in Japanese

Horses used to pull road-rollers, but the steamroller arrived with the invention of the steam engine.

He belongs to our tennis team.

Trucks came and dumped big stones on the road, then some trucks with little stones, then some trucks with tar and sand, and finally a steam roller came and rolled it all smooth, and the road was done.

The steam shovels dug down three stories on one side and four stories on the other side.
