The machine that was invented called the “crane” is equipped and fitted with a derrick or so also known as a tower. There are plenty of cranes that are used today, these cranes are able to pull things up and down with the built in pulleys and cables that is part of itself. There are plenty of those in the construction industry and the heavy equipment manufacturers that see cranes as an opportunity to build up their efficiency in construction of a structure and also can help their employee’s on the ground have a more easier time working. There are plenty of cranes that are being used in the construction industry and the these cranes that are being used don’t really stick too long to the area since when the structure is halfway complete or almost complete the use of a crane is a bit dwindled to the point that is no longer needed, cranes are built on vehicles that have the sole purpose of carrying these temporary structures although cranes can also be fixed on the ground if the workers deem it to be more efficient to use.
Various methods of controlling cranes are present with the help of modern technology and the construction industry have different methods in doing the controlling, such controlling methods are the normal and common radio control to the more complex infrared control to even also the more common control type which is a control station in where a person is required to man the station in which the person that is manning has to do all the commanding of the crane. Control stations are required to have a person manning them and the person manning them are also required to know the standardized hand signals so that the controller on the crane is able to communicate with the foremen/construction workers/personnel on the ground and can be able to identify which task is needed to be done as well to avoid any unwanted accidents that might occur. Plenty of materials can be loaded quickly to areas with great precision through coordination and signals that are being sent by an experienced crane crew and through this would enable the crane to function at its maximum capacity and efficiency.
As always, there are doubts from the public whether cranes are safe for the workers that are working on the ground, since lately there had been quite an increase in accidents that have resulted in serious injuries or even death due to crane related accidents. Construction companies have invested a lot of funds for the improvement of cranes whether be it technologically or just simple education programs for those that are using it to combat the high risk of crane related accidents.
