About Calipers

A vacuum excavator is a non-destructive digging machine that uses high-pressure air or water to loosen soil, which is then removed via suction. This method is widely used to safely expose underground services without damaging pipes or cables.

Coates offers reliable and easy-to-operate trailer mounted vacuum excavators for projects requiring flexibility and mobility. These self-contained 250-gallon vacuum excavation systems are ideal for service locating, trenching and excavation, with an integrated silencer for quieter operation in noise-sensitive areas. 

Designed for civil, construction and utility contractors, a trailer vacuum excavator helps avoid costly repairs and project delays by reducing the risk of damaging underground assets.
