A pin release mechanism which includes a release pin, a bias spring, a spring guide, a moveable ball retainer and a solenoid assembly. The release pin is axially movable from a first to a second position. The bias spring is connected to the release pin and exerts a force biasing the release pin towards the second position. The spring guide receives the bias spring interacts with ball bearings. The moveable ball retainer is connected to the bias spring and has a locked position in which ball bearings radially interfere with the movement of the release pin and prevents movement of the release pin from the first to the second position by engaging the release pin, and an unlocked position in which the ball bearings may move radially, disengaging the release pin, and engaging the ball retainer, to allow the release pin to move from the first towards the second position.
