The carriage includes two halves pivoted together which may be opened to remove the trolley from the rail and closed and locked to secure the trolley to the rail. The trolley restraint attachment point is preferably swingable from side to side with respect to the rail and includes a swiveling mounted attachment eye for the personnel safety line.
