What does the bridge crane signal with an extended arm, hand open and pushing motion signify?

The signal of an extended arm with an open hand and a pushing motion is commonly associated with the command for bridge travel in crane operations. This gesture indicates that the operator should move the bridge crane along its track. The open hand signifies a clear and direct command, and the pushing motion conveys a sense of forward movement, which is critical for safely directing the crane's movements in a work area.

Understanding this signal is crucial for ensuring safe operations, as effective communication between the operator and ground personnel is essential to prevent accidents and ensure that loads are moved safely and efficiently. Clear signals help in coordinating actions, particularly in environments where multiple cranes or workers may be operating concurrently.
