What is the main purpose of a signal person during crane operations?

The primary function of a signal person during crane operations is to guide the operator safely during lifts. This role is critical for ensuring that the crane moves and positions loads correctly while minimizing the risk of accidents or injuries. The signal person has a clear line of sight to the load and other site conditions, allowing them to communicate essential information to the crane operator. This communication is typically done through standardized hand signals or radio transmissions.

By providing guidance, the signal person helps the operator maintain awareness of the surroundings, avoid hazards, and ensure that the load is lifted and moved as intended. Their involvement is especially important in complex environments where visibility may be limited or when assisting in operations involving heavy or oversized loads. This coordination promotes safety and efficiency on the job site, making the signal person an invaluable member of the crane operation team.
