ABSTRACT:
An apparatus for moving a carriage along a roof structure of the type having a plurality of purlins spaced apart from one another in a parallel arrangement, and method of using same are disclosed. The apparatus includes a grappling member mounted for movement along the length of a first one of the plurality of purlins. The grappling member is adapted to be temporarily placed into a locked position so that the grappling member is fixed with respect to the first purlin. A tension member operatively connects the grappling member to the carriage. A pulling device is used to pull on the tension member so as to shorten the distance between the grappling member and the carriage, thereby advancing the carriage along the length of the purlins in a direction towards the grappling member when the grappling member is in the locked position.
