Perhaps just a generic term like construction site ? That is if we are assuming that this is being used to level the ground before something is built on it. That something could be anything. I'll add construction site and you can decide

The term appears in another area of the document describing the benefits of the same machine. The additional context is: Este sistema pode atuar nos cilindros de levantamento enquanto está utilizando os cilindros estabilizadores, mantém uma pressão constantes e é utilizado quando a praça está bem nivelado ou em outros solos mais macios, evitando que o tambor perca contato com a superficie a ser excavada.

This is heavy equipment that is used in leveling earth to build highways or prepare construction sites. Hope this helps
