In a news report appeared in Times of India, a person sleeping under the crane was crushed when the crane operated moved the crane. The person was crushed under rear tyres. Normally, we see persons / animals resting under vehicles, particularly in hot sun. The crane driver was arrested and a case was registered by police.
When I visited port trust in Chennai several years ago during industrial visit as a part of our safety diploma course, the authorities there told us that persons coming under vehicles is one of the most serious causes for accidents.
In port trust, movement of heavy vehicles and mobile cranes is common.
I see such hazard even on public roads, where reversing of all sorts of vehicles takes place, without regard for safety.
About, thirty years when I went to Vizag, I saw person in a pool of blood. I came to know the reason as reversing of bus from the stand.
I myself was hit on the ankle by a reversing car behind, in Chennai, and suffered for about three weeks. I was lucky not get fracture.
Authorities should seize vehicles without loud reverse horn and cancel the driver licence and vehicle registration immediately.
