Working in construction sites has always been considered as hazardous. In the period between 1997 and 1999, there were 158 accidents which can be considered as crane-related. 73 percent of these crane related accidents involved mobile cranes. Of this number, 10 accidents were caused by electrical contact. This gives people the importance of electrical grounding of mobile cranes.
Because of the crane’s height, there is a possibility that it will come into contact with electrical wires. And since the crane is metal, electricity can travel through it and can possibly injure the operator. Immobile cranes may not be in danger, but mobile cranes are another matter entirely. Mobile cranes, when being transported, have a very high potential of coming into contact with an electrical wire. This is the reason why mobile crane operators are very careful in their driving.
The importance of the electrical grounding of mobile cranes is that this feature prevents accidents from happening. Electricity acts this way: when a crane comes into contact with an electrical line, electricity travels through the metal trying to find the quickest path to the ground. When an...
