Bulldozers are typically designed for pushing earth and moving heavy materials across sites rather than lifting operations, which lessens the likelihood of contacting overhead power lines inadvertently. Their structure and use generally keep operators focused on moving materials on the ground, thereby reducing the risk of elevating components coming into contact with power sources above.

In contrast, excavators, cranes, and forklifts all have capabilities that may involve lifting and maneuvering loads to significant heights. Such functions increase the risk of these types of equipment accidentally coming into contact with overhead power lines, particularly if operators do not maintain proper clearances or are operating in proximity to those lines. For safety reasons, it’s essential for operators of excavators, cranes, and forklifts to be aware of their working environment and the potential hazards associated with overhead power lines, while bulldozers do not pose such a risk in typical operations.
