What must the operator be able to see when retracting or extending outriggers on a crane?

When retracting or extending outriggers on a crane, it is essential for the operator to have a clear view of the outrigger or to have an assigned watchman present to assist in the operation. This visibility is crucial for safe operation because the outriggers are critical components that provide stability to the crane during lifting operations.

Seeing the outrigger ensures that the operator can monitor its position and confirm that it is extending or retracting correctly without obstruction or hazard. If the outriggers are not positioned properly, it could lead to instability, which increases the risk of accidents. Additionally, a watchman can provide real-time feedback regarding obstacles or unsafe conditions that the operator may not see from their position, further enhancing safety during the maneuvering process.

Ensuring proper visibility of the outrigger or relying on the guidance of a watchman helps prevent accidents and supports safe crane operation as it encompasses both proactive monitoring of equipment and maintaining a clear operational zone.
