The crane, as a lifting device, is believed to have been invented in ancient Greece around the 6th century BC. Early cranes were constructed using wood and powered by human or animal labor, utilizing a system of pulleys and levers. They were primarily used in construction and for moving heavy materials, particularly in the building of temples and other large structures. Over time, the design and technology of cranes evolved, leading to the modern machinery we see today.
Construction worker hard hats were first invented in 1933 specifically for workers on the Hoover Dam.

A mobilization charge is often made for large equipment, a crane for example, to compensate the crane company for the time and expense to get the crane on site, erected and ready for work. The crane company will then charge by the hour as the crane is used. Mobilization fees are often charged as well on large construction projects to compensate the general contractor or construction management company for setting up the administrative offices for the duration of the contract.
