发明名称 Knock-down starting platform for a roof seaming machine
摘要 A knock-down starting platform for a roof seaming machine includes spaced side frame rails joined at one end with a platform on which a roof seaming machine may be supported and joined at their other end with a movable gate or bridge. Pins are also included to prevent disconnection of the frame rails once those rails are connected. The bridge carries a member which is adapted to be secured relative to a roof panel to support the rails and platform on a roof with the platform supported beyond the edge of the roof and the rails disposed in straddling relationship to the seam between adjacent panels. The side frame rails, the pins, latching device and bridge comprise a plurality of releasably connected together parts separable from one another to enable the starting platform to be disassembled for storage, shipment and handling in the form of a kit.
