Abstract

A self-raising platform assembly (1) comprising at least one mast (3, 5, 113) along which a platform (13) may be moved up or down including the following:
a) a base element (9) with a supporting plate (25) connected to a jack (27) and several stabilizer arms (33, 37) incorporating height adjustment. b) modular mast sections (7) made from rectangular sections with openings (63) cut out to form steps and bars (55) to allow adjacent sections to be bolted together. c) hydraulically operated ram lifting mechanism (73, 83, 84) with hooks (77, 79, 81) to engage steps on the mast to raise and lower the platform. d) a plastic lined sleeve (17, 19) on the platform which slides against the mast. e) a modular platform which can be lengthened or widened by adding additional modules (101, 103).
