The child asked me why bulldozers, excavators and cranes over 1 tons are much more expensive than Maserati's president. How to explain it clearly?

that's a good question. The president of Maserati is a high-end luxury car, and its price is very high, but the price of bulldozers, excavators, cranes and other construction machinery is even higher, because their design and manufacture require more materials, technology and labor.

first of all, construction machinery needs more materials to build. Large construction machinery such as bulldozers, excavators and cranes need to use a lot of steel and other materials to manufacture, and these materials are very expensive.

Secondly, construction machinery needs a higher technical level to design and manufacture. These machines need to go through complicated engineering design and manufacturing process, and need technical knowledge involving many fields, including mechanical design, electronic technology and control system. These technologies require higher labor costs and equipment costs.

finally, the service life of construction machinery is longer, and it needs more maintenance. Compared with cars such as President Maserati, construction machinery has a longer service life and needs more maintenance. These machines need more workers and equipment to repair and maintain, which also increases the cost.
