The various operating cranes on large scales and the other lifting equipment has very well become a very common practice in several industrial contexts as the electronic cranes are being widely used in the different construction and the factory sites throughout the nooks and corners of the entire globe. The excessive and the increased volume of the traffic, of the surface of the working areas and of the immense amount of the heavy loads in order to profit from the economies of the scale means that these handling of the extensive machines deal with the several hundred of the weights every working day. With an ever increasing use of the various heavy weight cranes, come a higher number of the probable crane accidents that in the best scenario result in the overall production delays and in the worst ones lead to the loss of the various precious human lives which is highly undesirable.
The numerous effective researches, the various extensive surveys and the recent studies conducted reveal that the main cause for the various unfortunate crane accidents during the course of crane operation is the lack of the required stability of the concerned machine. This can be caused for numerous reasons such as the surface where the crane is being positioned not being very uniform, the load to be lifted is exceeding the weight or the size of the crane is actually able to handle, or the cranes hoist not being positioned at the gravity centre of the load being lifted. For the measurement of the crane’s load, the maximum load capacity, a crane limit switch is being inserted in all the modern electronic cranes that are particularly being manufactured in the recent times.
The unfortunate incidents result in the loss of the precious human lives while the overall operations of the heavy handling machinery are in the majority of the cases due to the cases of the electrocution. The proper installation and the dismantling of the heavy weight cranes parts are also a very frequent cause for these very sad tragic events, as are crane components falling because of the faulty set up of the procedures while in the entire process of the manufacturing.
In the particular case of the quays and the commercial ports, the various accidents which are related to the crane operation in the container terminals represent as much as the 30% of the entire asset costs. The most common cause of the asset damage in such contexts is the impact between the booms and the ships from which the loads are being taken. The other frequent issues which are very well related to the hoists, the ropes, the chains and the spreaders which not being at their best condition and to some defective communication systems between the employees.
