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. Heavy equipment manufacturers and those that are in the construction industry treat cranes as one of the important parts of their work since cranes are able to do various activities that are interconnected with their process of building a structure. Cranes that are used in the construction industry are naturally and mostly a temporary structure that does not last long, it is built or mounted on a vehicle which the vehicle is specifically built to be able to carry the temporary crane or it can also be fixed to the ground either way is alright and being done.
There are multiple ways of controlling a temporary crane, these methods can either be infrared, radio control or even a built in operating station/control station in which the control station will be manned by a person which does all the pushing and pulling. 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. 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.
There will be questions from the public if the men and women that are working on construction sites are safe from accidents and cranes are no exception of accident prone machine, lately there had been a increase in grave injuries and deaths that have resulted from crane accidents. Employers and companies in the construction industry have taken action to combat and fight the high risk of crane operation, they have allotted funds to better improvise the technology that is related to the cranes themselves and they even allotted funds and have made educational sessions that would teach the workers how to avoid crane related accidents.
