I am not a crane operator/pwner. but even I can see (before the inevitable incident) the setup doesnt "look" right.
Angles bad, cranes seem stressed, booms fully extended and off vertical (e.g., lift a 50lb dumbbell straignt up, vs. holding it extended straignt out perpendicular to your body, while standing on one leg), etc,.
I did have a client once who was an OEM manufacturer of heavy lift cranes. They knew and definately published what their equipment could/could not do.
Users violate those requirements at the risk of this stuff happening.
hope nobody got killed in these examples.
