Cinema Rigging Physics & Fulcrum Safety
Hollywood Rigging ProtocolsFulcrum Moment Balance
3:1 REAR COUNTERWEIGHTCalculate required counterweight using W_cw = (W_payload Γ L_front + W_arm Γ L_cg) / L_rear. Always secure rear counterweight sandbags or barbell weights with safety linchpins before hoisting lighting fixtures.
1-1/2" Speed-Rail Rigidity
SCHEDULE 40 PIPEStandard 1.900" OD Schedule 40 6061-T6 aluminum pipe delivers a section modulus of Z = 0.326 inΒ³ and moment of inertia Ix = 0.310 in&sup4;, eliminating structural deflection and bending oscillations over extended overhead reaches.
Right-Hand Rigging Invariant
CLOCKWISE GRAVITY LOCKAlways rig cantilevered arms so gravity acts clockwise relative to the T-handle lock. Downward fixture weight actively tightens the brass friction disc against the knuckle, preventing catastrophic slip.
Complete Your Rigging & Boom Setup
Pairs seamlessly with 4-1/2" Lollipop Grip Heads, Heavy Combo Stands, 1-1/2" Speed-Rail pipe, and 25β35 lb heavy saddle sandbags.
Standard Hardware Lifetime Warranty
All Norms rigging hardware and stands are backed by a complete lifetime warranty against manufacturing defects.
