Summary of Contents for Steadicam G-70x

  • Page 2 It tames high/low arm travel with adjustable- length crankshafts that dynamically rock the spring termination as the arm is boomed up or down. Powered by coaxial titanium spring sets, the G-70x arm smoothly carries any load from 13 to 70 pounds (5.8 to 32 kg).

  • Page 4 Adjusting the ride or “iso-elasticity” The G-50x and G-70x arms have an adjustable active link as part of the “Geo” feature. This adjustable Setting Ride link gives the operator greater control over the dynamic changes, and thus more control over the arm’s performance.
  • Page 5 Setting Lift Adjusting the ride: the arm must be angled up at the top of its range. Note: the ride knob is horizontal, the lift knob is nearly vertical. Adjustment of Lift: All lift adjustments must be done while wearing the rig, standing properly, and with your normal threads in the vest to arm connection.
  • Page 6 Adjusting iso-elastic response: With the arm set to carry the load, we micro-adjust the Ride. If we dialed in too much iso-elasticity, the arm segments will “hang up” at Iso-elastic the upper or lower extremes of boom travel. If we dialed in too little iso- elasticity, the arm may not track well in the middle of its range.
  • Page 7 The idea is to get the socket block both closer to the body and to the Steadicam sled. Why? See the next tip. When using any back mounted vest, all arms are more extended from the load (the sled) to the attachment point (the socket block).
  • Page 8 That way when raised, the operator is lifting a little, the torque is reduced correspondingly and the transferred torque is likewise reduced – hence a smaller tendency for the upper arm section to lock up. Even with the iso dialed down, the G-70x’s response in the +/- 50 degree range is more iso-elastic than other arms.
