HPT-28 horizontal specialized drilling rig, is trenchless equipment that drills a curved underground path for installing pipes, cables, and conduits (like water, gas, fiber optics) without digging large trenches, allowing for crossing obstacles like roads, rivers, and sensitive areas with minimal surface disruption. It works by drilling a pilot hole, enlarging it with reamers, and then pulling the product through, using a tracking system to guide the drill bit precisely.
