- Catenary: Platform supported by two essentially horizontal and parallel ropes attached to structural members of a building. Additional vertical pickups may also provide support.
- Multi-point Adjustable: Platform(s) suspended by more than two ropes from overhead supports and equipped with a means to permit the platform to be raised and lowered. Includes chimney hoists.
- Interior Hung: Platform suspended from the ceiling or roof structure by fixed-length supports.
