Cranes are one machines that are installed with a tower or derrick. 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. The construction industry and those that work within the heavy equipment manufacturing companies have the mindset that cranes are an essential part of their business since cranes help them ease their work and create some breathing space for their workers on the ground, cranes have the ability to do various activities that are intertwined with the process of building a structure. 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. When it comes to a control station being used as a controlling method, then it is required to have a standardized hand signal communication method to be used so that the controller on the crane would be able to identify what task is required for him or her to do and to be able to avoid accidents with the personnel on the ground that are working or the fragile equipment that is being used. A lot of time would be saved and materials that are badly needed to some parts of the construction site would be sent easily and efficiently through the help of experienced crane crews that are familiar with the hand signals and the commands that the crane has.
When it comes to cranes being reliable or safe to the health of the personnel on the ground then it can be a question that would be hard to answer, in the last several years there had been a sharp increase in bad injuries and even death that has resulted from crane 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.
