A support platform 50 comprises a frame 10 adapted to rest on the root wherein the frame 10 includes a pair of support members 11 each having engagement means and a platform 50 connected to the frame 10 by a hinge. The platform 50 is for supporting a roof seaming machine at an edge of a metal roof. The support members 11 may include arms 12. The frame 10 may further comprise a pair of vertical columns extending upward from opposite ends of the arms 12 and a handle 34 may be connected between the columns. The engagement means preferably comprise a channel member 16 having a slot 18 through which a portion of a roof seam may protrude to allow the assembly to be clamped (P, figure 2) to the roof. The platform 50 is preferably allowed to pivot upward freely, but has it's downward motion restricted by wire cables 58 which extend between platform 50 and columns. The hinge may comprise a knuckle 28 attached to each arm 12. The platform 50 is shaped so as to allow a roof seaming machine to seam a roof without interference from the platform itself, ie, the platform does not connect to the seam to be joined, but to the two either side of it. |
