Abstract
A safety latch system includes a mount, a pawl member, a ratchet member, and a release assembly. The mount is mountable on a housing of a piston. The pawl member is coupled to the mount. The pawl member includes a pawl. The ratchet member has a first sidewall that includes a first connecting portion that is connectable to an end portion of a piston rod of the piston. The first sidewall includes a teeth portion, which is configured to engage with the pawl. The release assembly is configured to provide an engaged state between the pawl member and the ratchet member. The release assembly is also configured to provide a disengaged state between the pawl member and the ratchet member. When in the engaged state, the pawl member is engaged with the ratchet member such that the safety latch system is configured to provide (i) an unlocked state in which the ratchet member is movable relative to the pawl member as the piston rod advances outward from the housing and (ii) a locked state in which the pawl member is configured to lock into a depression between adjacent teeth of the ratchet member to stop the piston rod from moving towards the housing. When in the disengaged state, the pawl member is disengaged from the ratchet member to permit the piston rod to advance outward from the housing and permit the piston rod to retract towards the housing.
