  • Patent number: 6267201
    Abstract: A method of performing roof construction work on a roof with inclined rafters using a work platform which includes a structural frame (10), an upper work surface (15) having multiple removable sections (16) mounted by the frame on which a worker can move about on the platform. A safety barrier (20) extends around the periphery of the upper work surface. Mounting feet (30) secured to the frame are located at predetermined positions enabling the feet to rest on the rafters and releasable fastening means (31, 41) are associated with the feet to secure the platform in position for work on the roof structure. The mounting feet (30) include abutment feet (40) which rest on the rafters of the roof structure and which are clamped to the rafters. At least one mounting foot (30) comprises a fixable mounting foot (31) which can be releasably fastened to the roof structure to prevent lifting movement, longitudinal sliding movement, and lateral displacement of the work platform relative to the associated rafter.
