Milo Long Arm — Toppling Risk During Arm Reconfiguration

DANGEROUS CONFIRMED MILO FLAIR CLASSIC FLAIR 7

Summary

The Milo Long Arm has a high centre of gravity when the arm extension is at or near full extension. During physical arm reconfiguration — changing the arm section layout, removing counterweights, or repositioning the arm segments — the rig can become unstable and topple if the correct procedure from the Assembly Guide is not followed exactly.

Toppling hazard — severe injury or equipment damage risk

A toppling Milo arm can cause serious injury and will destroy the arm and potentially the track. Always follow the MRMC Long Arm Assembly Guide (MRMC-1283-00) procedure when reconfiguring. Never leave the arm in an extended configuration unattended.

When This Risk Applies

  • Adding or removing long arm extension sections
  • Rebalancing counterweights
  • Repositioning camera mount or payload
  • Moving the rig with arm partially extended (transport)
  • Any procedure that temporarily changes the arm's centre of gravity

Key Safety Rules

  1. Read MRMC Long Arm Assembly Guide (MRMC-1283-00) before any reconfiguration. The guide specifies the exact sequence for adding/removing sections and adjusting counterweights.

  2. Retract the arm fully before any reconfiguration. Never work on arm sections with the arm extended.

  3. Use two or more people. Never attempt arm reconfiguration alone — one person must hold/support the arm at all times.

  4. Counterweights must be in position before extending the arm. Extending without correct counterweights will cause the rig to topple rearward.

  5. Never leave the arm extended and unattended — even if secured, environmental disturbance (doors, passing trolleys, vibration) can destabilise it.

  6. On location: use outrigger feet. The Milo base feet must all be properly deployed and levelled before arm extension.
