Metal roof installation system

Abstract

A system for installing a metal roof system including an insulation layer placed over a series of purlins and under a metal deck while preventing workers from falling through the insulation. The system is primarily comprised of a material handling assembly and a working deck. The material handling assembly includes at least one conveyor segment positioned across the purlin. Each conveyor segment is comprised of a rectangular frame in which is disposed a series of rollers. The rollers are disposed in parallel fashion relative to each other and in a lateral direction with respect to the frame. A roller assembly is secured to the conveyor segments at each purlin in order to accomplish lateral movement of the system as the roof installation process progresses. At least one winch is mounted to the material handling assembly, from which is extended a winch cable. The winch cable is secured to the far end of the building. The working deck is secured along a leading edge to each roller assembly and is fabricated from a corrugated metal such as to withstand the weight of several roofers, as well as materials and other equipment necessary to the installation of a metal roof system. A safety cable is provided on the leading edge of the material handling assembly to serve as a fall barrier. After a sufficient number of roof panels have been secured to the purlin, a retractable handrail and skid assembly is employed on each end of the trailing edge of the roof in order to provide a fall barrier for workers employed on the roof.
