Hold down and release actuators

Tension releases

Eaton's non-explosive actuator solutions include G&H Technology tension releases.  These low-shock devices provide rapid releases with low power consumption.

Core features

  • Threaded, clevis pin, and custom load attachments available.
  • Safe handling and deployment; non-explosive actuators do not require the explosive materials precautions associated with pyrotechnic actuators.
  • Factory refurbishment significantly reduces actuator-related test and qualification costs.

Fragment & debris free releases

Tension releases utilize split-spool initiators as hold down preloading assemblies and threaded or clevis-pin load shafts as hold down release actuators. After electrical initiation, load deployment is facilitated by internal release of the load-attachment shaft.

Tension releases are available in standard load ratings up to 1300 pounds (5.8 kilonewtons) and a separation stroke of 1.1 inches (28 mm). Customer-defined load ratings and separation-stroke lengths are also available.

 Heritage proven, custom-solution capabilities

Eaton's tension-release flight heritage includes exo-atmospheric military programs and space exploration programs that extend from low-earth orbits to landings on Mars.

The technologies used in these critical applications can be leveraged to accelerate the development of custom hold down and release mechanisms to support a wide range of mission requirements:
