Construction equipment can be quite dangerous, and perhaps the one machine that requires the most oversight is that of the crane. From all of the different ranges of cranes, there are manuals and diagrams that operators need to use to determine how much they can lift at what boom heights and what angles. Unfortunately, many people often overlook these calculations and decided to "just go for it." While this may seem good in the moment, it ends in disaster more times than not, like this recent crane crash. Check it out.
