In fact, there are mainly two kinds of ceiling you may need to consider . So different ceiling you need different way to hang lighting truss from.
the first kind of ceiling
it is those who has visible steel (or other building material ) trussing structure system. such as airport or exhibition hall and other large building ceiling with trussing structure.
for this kind of ceiling, you need to attach "clamps" on the truss, and then using rigging and wiring to rings or hooks, attching to existing structure on the ceiling.
the second kind of ceiling
it is those who do not have visible trussing structure, and at very begining, the building not intend to hang truss from ceiling. such as living room ceiling.
for this kind of ceiling, there are 2 ways to have lighting truss on the ceiling.
to form a truss structure with pillars from ground to ceiling, and hoist trusses through the truss system to the ceiling. this way is the same installing a truss system on the ground as build a truss system outdoor.
to drill holes on the wall or ceiling by professional workers, and build anchors there, then form a simple but firm structure on the ceiling. then using clamps and rigging, wiring to hang lighting truss as the first way.
