摘要： A furling crane loading platform (1) comprising: a cantilever support base (3); a first stage (2A) pivotally coupled to the cantilever support base (3); and a second stage (2B) pivotally coupled to first stage (2A). In an unfurled configuration (2B) the first and second stages provide a substantially horizontal crane loading surface extending from a building edge (11). The platform is configurable into furled configuration (2A). The platform may further comprise a third stage pivotally coupled to the second stage, fourth pivotally coupled to the third stage, hydraulic actuators (16), controller for controlling the stages in a sequence, sensor for sensing the configuration of the stages, detachable cantilever support beams (4) with a downward transition portion (19), props (5) to prop the cantilever support beams against an under surface of a floor slab and lockout mechanism (17).
