RETRACTABLE LIFELINE ASSEMBLY
A retractable lifeline assembly includes a housing including a sidewall, a rotatable member inside the housing, a first engaging mechanism coupled to the rotatable member, and a crank including a crank handle and a second engaging mechanism. The crank is pivotally coupled to the sidewall such that the crank is selectively movable between a first crank position, in which the second engaging mechanism is engaged with the first engaging mechanism, and a second crank position, in which the second engaging mechanism is disengaged from the first engaging mechanism. The crank handle selectively engages the first engaging mechanism when the crank is in the first crank position to rotate the rotatable member.
