Spaces with low ceilings present a particularly challenging situation for those wishing to use backdrops. And olio drop is a form of a roll drop with a tube is at the bottom. Here are some terrific examples of their use and construction from around the Internet. Credits and copyright belong to those people and sites referred to within.
Rigging of an Olio Drop can be done in spaces with fairly low ceiling heights. The top just needs to be high enough to be out of view of the audience. There are, of course, times when seeing the rigging above is acceptable. This depends on the overall concept of the design, but that’s another topic.
The illustration to our right shows a traditional Olio Drop with a batton at the top of the drop and a light weight pipe or tube on the bottom. The top is stationary with the drop hanging down from ropes. The tube is pulled up via rope from off stage. When the rope gets pulled it forces the tube to climb the cloth of the drop itself
This Pin from Pinterest shows a rudimentary version of the Olio Drop. Pulling on the rope doesn’t have the same force on the bottom pipe as our other example. Pulling on your “fly” line rope will likely cause the pipe to roll as you pull on the rope, but the pipe isn’t climbing the drop in the same way.
