Professional HDD Swivel

The Colli Equipment HDD swivel is an anti-torsion rotating joint designed for pipe installation during Horizontal Directional Drilling (HDD) operations.

During pullback, it transfers the pulling force from the drilling rig to the pipeline while eliminating the rotation transmitted by the drill rods. This reduces torsion and mechanical stress on the pipe, helping make one of the most critical phases of the job safer, smoother and more controlled.

Applications

HDD Swivel for Pipe Pulling

This directional drilling swivel is designed for HDD contractors, trenchless operators and companies involved in the installation of steel or polyethylene pipelines.

It is suitable for HDD pullback operations, pipe pulling and, in some cases, borehole reaming on smaller-scale projects. Its purpose is to manage pulling force, reduce torsion and support the controlled installation of the pipe into the borehole.

Advantages

Built for Pullback Loads

Every Colli Group swivel is engineered to deliver strength, control and reliability in demanding HDD applications.

Bidirectional capability

Designed to withstand axial tensile loads during pullback and axial compression loads when pushing.

SKF Explorer

SKF Explorer thrust bearings for extreme loads (radial and axial), longer life and reduced maintenance.

Protected internal lubrication

The quick-greasing system reduces friction and wear, helping protect bearings from contamination.

Clevis End Connections

Dedicated end connections help reduce misalignment and radial loads during pullback.

Safety Locking Pin

Anti-release and anti-rotation locking system for secure assembly pin retention.

Product traceability

Stamped serial numbers allow materials, machining processes and treatments to be traced.
