Abstract: A piston lock system comprising: a cylinder, a rod receiver fixed to the cylinder, a piston slidably mounted to the cylinder, and a rod fixed to a free end of the piston and extending parallel to the piston to be located within the rod receiver. The piston and rod are movable relative to the cylinder and rod receiver between a retracted position and an extended position. A lock pin is mounted to the rod receiver and movable between a unlocked position in which the lock pin does not intersect a path of the rod, and a locked position in which the lock pin intersects the path of the rod and prevents the rod and piston from moving to the retracted position. Lock pins of multiple actuators can be connected to operate in unison.

Abstract: A piston lock system having first and second cylinders, first and second pistons telescopically connected to the cylinders, and first and second piston locks. The piston locks are movable in a transverse direction within a planar region between the cylinders, between unlocked positions in which the piston locks are not located between the free ends of the cylinders and the free ends of the piston, and locked positions in which the piston locks are located between the free cylinder ends and the free piston ends. A control link is operatively connected to the piston locks, and configured to simultaneously move the piston locks between the locked and unlocked positions.
