I've come up with a few reasons, if someone could add on to it then that would be wonderful!Thank you for answering my question :D
A crane allows us to place light or heavy loads with precession and safety; on top of buildings, across water ways, down mine shafts and over obstacles. Building a pyramid today would be done with cranes, instead of building ramps to slide the massive stone blocks up. Cranes speed up any construction project. Cranes eliminate a lot of manual labor. Cranes prevent injuries by doing the hard work. One example, we used a crane to lift off an entire house roof, in one piece. We then built a second story and then used the crane again to put the roof back on. Without a crane, it would have taken several days to tear off the shingles, remove the roof sheeting and the trusses, not to mention the money saved. The building codes do not allow the reuse of wood trusses, yet not taking the roof apart, allowed use to reuse the trusses, a savings of hundreds of dollars. Wingman
