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)
