What Does Light HDD Rig Mean?

A light HDD rig is a horizontal directional drilling unit that is smaller and lighter than conventional HDD rigs. Physically, they typically weigh less than 82 tons and are capable of producing bore diameters between 51 mm (2”) and 914 mm (36”). Light HDD rigs are ideal for relatively short crossings ranging from 300 m (984’) to 500 m (1,640’).

Trenchlesspedia Explains Light HDD Rig

HDD rigs are used to install underground pipes, conduits, and cables using a guided, surface-based rig to launch a drill to create a subsurface pathway. These HDD rigs usually fall into two categories: light rigs and heavy rigs. Although these two types of rigs perform essentially the same function, they each have benefits that lend themselves to different situations.

Light HDD rigs are more nimble and portable, making them better suited for short utility installations. This equipment requires a smaller drill pad and occupies a smaller footprint, allowing it to operate in tighter and more confined areas than larger machinery.
