Using a larger steadicam arm to exceed weight capacity of a Zephyr rig

What the thread found

  • A Zephyr steadicam rated for 10 kg can potentially carry a load exceeding its rating by using a G50 arm, but requires hardware modifications and carries risks to other components.
  • To adapt a G50 arm to a Zephyr rig, a larger socket block for the vest and a properly sized arm post are necessary.
  • Overloading a steadicam rig beyond its rating may cause damage to components like the gimbal, gimbal yoke, or stage-to-post junction.
  • A longer arm post needed to balance an overweight load can introduce vibration issues.
  • Using dual battery plates positioned low on the rig can help reduce the need for excessive arm post length when carrying extra weight.

Depends on

  • This modification was discussed for a specific mission and may not be suitable for regular use.
  • The solution requires custom machining or sourcing an adapter block from the manufacturer.
  • The approach was described as temporary and for a specific project, not a recommended permanent upgrade.
  • No long-term testing results were reported on gimbal durability when operating overloaded.
