Engineered and manufactured for rugged reliability and reduced maintenance, our field-proven Hydra Rig™ manufacturing and injector tackles the new demands that come with quench and tempered coiled tubing, such as Quality Tubing™ ATP-130 . While offering weight savings over our largest injector offering, the HR-6120 maintains the dependability you expect from Hydra Rig.

Whether you are packaging a new, custom-built unit with the HR-6120 model injector or replacing an existing one, the HR-6120 can be retrofitted on most of our existing units within the footprint of many of our injector models. 

Designed to handle 2- to 2⅞-in. coiled tubing strings, this model is capable of running 140,000-psi designs with superior slow-speed control (inches per minute). The HR-6120 has an 120,000-lb continuous lifting capacity and 60,000-lb continuous snubbing capacity. 

The drive system and traction system included in our design enhances performance in the field.
