Suspendable conveyor trolley for façade elements for high-rise buildings and related systems

A system (700) for horizontally conveying a façade element (230) along a façade of a high-rise building (200), wherein the system (700) comprises a suspendable conveyor trolley (300) for horizontally conveying a façade element (230) along a façade of a high-rise building (200), wherein the suspendable conveyor trolley (300) is adapted to be suspended on a guide rail (400) that runs horizontally along the façade (220), wherein the suspendable conveyor trolley (300) comprises:

• a trolley elongated element (310) adapted to engage with a façade lifting elongated element (235) adapted to be attached to the façade element (230), to carry and convey the façade element (230) along the façade, wherein the trolley elongated element (310) comprises a trolley hook portion (320), having a hook shaped cross-section and being adapted to receive a lifting hook portion (236) of the façade lifting elongated element (235);
• and
• a movable locking member (330) that is movably attached to the trolley elongated element (310) and mechanically biased towards a locking position (P1), in which the trolley hook portion (320) is blocked by the movable locking member (330), wherein the movable locking member (330) is adapted to be moved by a lifting jig (500) away from the locking position (P1) when the lifting jig (500) reaches and engages with the façade lifting elongated element (235), and wherein the term “blocked” means hindering of unintended or undesired removal or release of the façade lifting element, specifically, by blocking the trolley hook portion (320), the lifting hook portion (236) is prevented from leaving the trolley hook portion (320) when the façade element (230) is hanging in the trolley elongated element (310);
• and
• a lifting jig (500) adapted to vertically guide the façade element (230) along the façade, wherein the lifting jig (500) comprises a projecting portion (510) adapted to contact and move the movable locking member (330) of the suspendable conveyor trolley (300).
