Monster Hoist on the 37th Floor lifting four curtainwall panels. The vertical mini-ADT tracks are attached to the building's integral window washer tracks, the length of the tracks growing as the curtainwall installation progresses. The panels are then transferred to the full perimeter monorail system, itself designed to be periodically hoisted just ahead of installation work.
