A locking gas spring incorporates a mechanism to enable the rod to be locked at any point in its travel. This mechanism is actuated by a plunger that protrudes from the rod. When this plunger is depressed the rod is free to operate as normal. When the plunger is released, which may be at any point in the stroke, the rod is locked in that position.
STON offers three types of locking gas springs, which have the following characteristics when locked:
- Flexible good resistance to rod being pushed or pulled
- Rigid in tension Rigid when rod is being pulled, high resistance to rod being pushed
- Rigid in compression High resistance to rod being pulled, rigid when rod is being pushed
