Abstract (en)
[origin: US4960185A] The invention relates to a vertically and horizontally movable work platform 4 for carrying out renovations to the concrete on reinforced concrete buildings or for replacing the structural protection on steel constructions. To increase the operational safety these work platforms 4 are held against the surfaces 1 of the buildings by attached magnetic plates 6. Since the tensions cables previously required are dispensed with, the weight of the upper carriage 2 from which the work platforms are suspended by cables is considerably reduced.
