• The mechanical locking device is a physical and mechanical locking mechanism used when the spring’s piston rod is extended.
• It prevents a sudden retraction of the spring.
• The mechanism is attached to the piston rod in an off-center position.
• When the rod is extended, the support tube on the flat side of the sleeve can be pressed.
• This engages a mechanical lock that prevents retraction.
• The safety lock is often used on vendor stands and must be disengaged manually.
