History of Cranes
If we make a bit of history, the origins of this machine go back to the shaduf. This loading system was very much in vogue in the merchant ships, whose crew members were in charge of driving, in a constant loading and unloading process.
However, with the passage of time, the renovation of the strut became imperative, especially since it needed to be operated by a large number of individuals, which delayed the process of unloading the materials themselves.
The crane was constituted in the direct evolution of the prop used for the transfer of heavy loads. This machine is equipped with a forklift, with ropes whose function is to raise and lower the respective materials, as well as moving the load by making horizontal movements.
The crane is also composed of a boom (or arm) that is mounted on an axis that performs rotating movements. In addition to this, the crane consists of one or more pulleys that lift the weight and then move it from one sector to another.
