how do i operate two cranes that are close together

When operating two or more cranes to lift a single load, it is crucial to have one qualified person in charge of the entire operation 1, 4, 18. This designated person is responsible for analyzing the operation and instructing all personnel on proper positioning, load rigging, and movements 1, 4. Clear communication and adherence to a standard signal code are essential for safe operation 1, 3.

To ensure safety, avoid bumping into runway stops or other cranes [1]. If cranes must engage or push other cranes, do so with extreme caution to protect personnel [1]. Also, maintain adequate clearance between parallel cranes to prevent collisions [2].

Before starting, verify that all crane operators are qualified and trained 1, 7, 13, and that the load does not exceed the crane's rated capacity 12, 15, 20. Inspect all ropes and equipment before use, and address any unsafe conditions before resuming operation 15, 16.
