Abstract: A fall protection system includes a mast assembly including a fixed mast section, a movable mast section, and a winch assembly. The fall protection system further includes a locking mechanism adapted to lock the movable mast section relative to the fixed mast section. The locking mechanism includes a locking pawl connected to the winch assembly. The locking pawl is adapted to rotate between an engaged position and a disengaged position. The locking pawl engages with the fixed mast section in the engaged position to prevent relative movement between the fixed mast section and the movable mast section. The locking mechanism also includes at least one spring adapted to bias the locking pawl towards the engaged position. Further, the winch assembly is adapted to retain the locking pawl in the disengaged position against the biasing of the at least one spring based on a tension selectively applied by the winch assembly.

Abstract: A fall protection system includes a base assembly, a mast assembly, and a locking assembly adapted to lock the mast assembly with the base assembly. The locking assembly includes a first plate and a second plate. The locking assembly also includes a fixed member fixedly coupled to the second plate. The locking assembly further includes a locking pin including an elongate portion at least partially received within the fixed member and a first tab, the locking pin being movable relative to the fixed member between an engaged position and a disengaged position. In the engaged position, the first tab is at least partially received within a first groove such that the locking pin is engaged with the first plate. Further, in the disengaged position, the first tab is at least partially received within a second groove such that the locking pin is spaced apart from the first plate.
