What did Operation Crossroads test?
Three tests were envisioned for Operation Crossroads: a Hiroshima-like burst (Able shot), a shallow underwater burst (Baker), and a deeply submerged explosion (1000-2000 feet below the surface).
How was the Baker test different than able the previous bomb test?
The greatest difference between the Able and Baker Tests was the radioactive contamination of all the target ships by Baker. According to the initial report by the JCS Evaluation Board, the radioactive hazard produced by the spread of water was so dangerous that…
What were the consequences of Operation Crossroads?
35% of these animals died or were euthanised in the three months following the explosion: 10% were killed by the air blast, 15% were killed by radiation, and 10% were killed by the researchers as part of later study.

What caused the crane to flip over in Rostock?
The crane’s twin boom and jib appears to have flipped over the rear while lifting a test load at the Liebherr yard in Rostock. We are told that the incident was caused by the failure of a wire rope during an overload test, but this has not yet been confirmed.
What caused the crane to collapse at Liebherr?
The crane’s twin boom and jib appears to have flipped over the rear while lifting a test load at the Liebherr yard in Rostock. We are told that the incident was caused by the failure of a wire rope during an overload test, but this has not yet been confirmed. The collapse was captured on video which you can see below.
What are the most common crane safety hazards?
Electrocution Electrocution is a grave crane safety hazard that crew members should take extremely seriously. All workers, including the operator, are responsible for spotting for electrical hazards. Given the heights that cranes reach, the crane’s boom could make contact with overhead power lines.
What are the most common overhead crane overhead rope problems?
Birdcaging, corrosion, abrasion, and extreme wear are a few of the problems that can affect wire rope on an overhead crane. The best way to prevent damage or failure is to inspect your wire rope regularly. Damage or degradation to wire rope is one of the most common issues that you may experience with an overhead crane system.
