Pin Pullers / Pushers

Pyroalliance designs and produces pyrotechnic Pin Pullers and Pin Pushers. Those are dedicated to maintain the holding position of a mechanism aiming to be deployed or ejected after the pin is activated. In most cases it will prevent the linear or rotational motion of an object. For example helicopter rocket canisters use Pin Pullers as an arming signal confirmation and allow the rocket to be operated once removed. Pin Pushers, at the opposite, will create a movement to push or break another mechanical piece such as missile inlet cover or gas bottle cap for fire suppression. The overall dimensions as well as piston strokes are adjusted depending on the application.

More generally, Pyroalliance delivers complete pyrotechnic chains adapted to its customers’ needs.
They are designed and manufactured under Pyroalliance design authority.
