Single Purchase

This type of counterweight flying system is normally the most cost-effective to install in a venue but it requires certain criteria to be met in order to do so.

The vertical travel of the scenery bar is equal to the vertical travel of the counterweight cradle. For a single purchase counterweight system to be installed; sufficient space and unobstructed height must be available to enable the necessary structural and moving components to be accommodated.

Loading for a single purchase counterweight set is relatively simple; 1kg of weight applied to the scenery bar must be counter-balanced by 1kg of weight loaded into the counterweight cradle.

Similarly; 1m of vertical travel of the counterweight cradle will result in 1m of scenery bar travel.
