Hoist-pulley distance requirements
Depending on how far the chandelier needs to drop will determine the required minimum distance between the hoist and the first pulley.
As a rule of thumb, if the distance is greater than or equal to 10 feet the distance requirement will always be met. If a shorter distance is desired calculations* will need to be done to find the minimum distance allowable.

The mounting plate was designed for worst case scenarios and against all expected failure modes.
A minimum required thickness was determined from these calculations* and rounded up to 0.5”. The plate width and length may be adjusted according to which system components will be attached to it. The chandelier hoist, electrical reel, and safety strap will all fit on a 3’ x 3’ plate.
