1. A window wall system, comprising:
a sill receptor secured to an upper surface of a first floor slab, the sill receptor providing a base and an upright member extending from the base;
a head receptor secured to a bottom surface of a second floor slab vertically offset from the first floor slab;
a glazing unit providing a sill, a head, and one or more panels extending between the sill and the head;
a first hook defined by the sill and engageable with the upright member, wherein the first hook extends downward and thereby defines a downwardly-opening channel sized to receive the upright member such that the glazing unit is pivotable about the upright member toward a vertical orientation; and
a second hook defined by the sill and receivable within a groove defined by the upright member in the sill receptor when the glazing unit reaches the vertical orientation, wherein the groove extends substantially parallel to the base.
