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)
