Mobile Crane
Hand Signals

Crane signaling is paramount to safe and efficient crane operations.  Hand signals become especially important when:

  • The operator’s visibility of the load or rigging is impaired
  • The operator cannot see the entire path that the load is to follow
  • The operator’s view of the landing area is impaired or blocked by obstructions
  • The load is far enough away that judging distance is difficult
  • When the crane is working within a boom’s length of safe working limit to power lines

There is more to giving good signals than memorizing the hand signal chart

  • Pay attention to how the crane and load moves when the operator follows your signals.
  • Discuss the signals and lift path with the operator prior to making the lifts
  • Position your hand away from your body and so the operator can see it clearly.
  • Ensure that everyone is ready prior to lifting or setting a load
  • Keep a clear view of the operator, load and entire load path
  • Use a middle man to transfer signals if it is not possible for one person to see everything (radios can also be used)
