Topcon i-33 installs quickly and easily on pull type scrapers, or motorized scrapers. It eliminates the need to wait for a surveyor to place elevation stakes and results in a more efficient approach to mass excavation. The i-33 system can be configured with single GNSS or dual GNSS antennas and can be installed on different machines that require elevation indication. Installation requires minimal welding on the machine, making the i-33 easy to switch between a dozer, scraper or motor grader.
