Cranes are an important piece of equipment for many construction sites because they provide the ability to move very heavy objects for building giant things! Cranes have been one of the greatest inventions for modern building. Before, the only way to build great things was to use muscle and this is inefficient compared to the amazing ability cranes have. These machines can make their way on the back of trucks with support beams as well and can be transported to work remotely! The biggest of cranes build metropolises in major cities and can reach up to 100 meters tall!
