Why must most cranes be disassembled for transport?

The correct answer highlights that cranes often weigh too much for a single load during transport. Cranes can be massive structures, and their components may exceed weight limits imposed by road regulations for transportation vehicles. Transporting a fully assembled crane would require specialized vehicles and permits, not to mention the increased risk of accidents due to their size and weight. Disassembling a crane allows for the distribution of weight across multiple loads, making transportation safer and more compliant with weight regulations.

While it is true that cranes may require special permits for transport, the primary reason for disassembly is to manage weight limitations effectively. Furthermore, the complexity and oversized dimensions of cranes often necessitate transportation strategies that cannot accommodate the full structure intact, leading to the need for careful planning and logistics in transporting each component separately.
