Claim 11:
12. A fall protection system comprising:
a base assembly;
a mast assembly rotatable about a first axis defined by the mast assembly; and
a locking assembly adapted to lock the mast assembly with the base assembly, wherein the locking assembly includes:
a first plate fixedly coupled to the base assembly, wherein the first plate defines a plurality of through-holes and a plurality of slots, such that each through-hole of the plurality of through-holes is in communication with a corresponding slot;
a second plate fixedly coupled to the mast assembly;
a fixed member fixedly coupled to the second plate, the fixed member defining a first groove and a second groove; and
a locking pin including an elongate portion at least partially received within the fixed member, a first tab extending from the elongate portion, and at least one second tab spaced apart from the first tab, the locking pin being movable relative to the fixed member between an engaged position and a disengaged position,
wherein, in the engaged position, the first tab is at least partially received within the first groove, the elongate portion of the locking pin is received through a corresponding through-hole of the plurality of through-holes such that the locking pin is engaged with the first plate, and the at least one second tab is misaligned with the slot in communication with the corresponding through-hole that receives the elongate portion of the locking pin therethrough, and
wherein, in the disengaged position, the first tab is at least partially received within the second groove such that the locking pin is spaced apart from the first plate.
