Engineering Application and Web Tension Information Dancer Loading Recommended Not Recommended 1. Rolling diaphragm type pneumatic cylinder for its low friction characteristics 1. Weights impede rapid dancer arm movement by adding mass to dancer arm 2. A pressure regulator with high volume flow capacity and fast relieving vent to allow rapid movement of dancer 2. Springs provide inconsistent loading, since spring force changes with deflection 3. Shock absorbers resist changes in dancer position by dampening Engineering Application and Web Tension Information 5
