Cranes have come a long way from what they once were. No longer are they the clunky, rickety machines of the past. Technology has most of all improved their speed, strength, and capacity, over the years, at the same time making them lighter and easier to operate. Cranes have become an absolute necessity in several industries. They can make your job easier; however, cranes are more commonly the cause of on-the-job accidents than any other heavy equipment. They account for more than 20% of all deaths associated with construction jobs.
