Troubleshooting a stiff or difficult-to-collapse center post on professional camera cranes

14 years old. Gear and prices may have changed since.

What the thread found

  • Twisting the lower sled section in opposite directions relative to the upper section can help reduce friction when a center post is hard to collapse.
  • Detaching the junction box and twisting the post cable can alleviate binding between the cable and post interior.
  • Rotating the lower mount clockwise while the bottom sled is detached tightens the cable coil diameter and reduces friction with the post walls, but this reduces maximum extension length and increases cable strain.
  • Over-tightening during previous use can cause rubbing between outer and inner post sections and make collapsing difficult.
  • Worn or damaged inner post sections may require replacement to restore smooth operation.
  • Talcum powder applied to the post walls can reduce friction.
  • Silicone lubricant applied to the interior walls may help reduce friction, though this approach is not officially recommended by the manufacturer.
  • Ensuring low-mode dock rings are not overtightened can prevent collapsing problems.

Depends on

  • The quoted manual tip could not be located in currently available manuals, suggesting it may be from older documentation or misremembered.
  • The lubricant approach is acknowledged as potentially unsanctioned by the manufacturer.
  • The cable-twisting technique involves a tradeoff: reduced friction comes at the cost of reduced extension range and increased cable strain.
  • Experience reports vary by post generation, with Gen 1 posts reportedly having different tolerances than Gen 2 HD posts.
  • The exact tolerances between inner and outer post sections are noted as very tight, making most modifications risky.
