Felling’s Horizontal Directional Drill (HDD) trailers are built to handle the demands of transporting directional boring machines used in trenchless underground utility installation. HDD provides a minimal-impact solution for installing underground utilities such as pipes, conduits, and cables beneath the surface. To support a wide range of drilling equipment, Felling offers two dedicated HDD trailer lines: the Drop Deck I Drill Series (12K–27K) with a deck-between-the-wheels configuration, and the Low Pro Drill Series (30K–50K) featuring our durable deck-over flatbed tag design.
