This is the most common way to park when the excavator is transported. This parking can minimize the height and length of the excavator. It will not be super high and long after loading, which is convenient for transshipment of flat transport vehicles.

If it is rain or snow, or there are construction operations such as shooting in the vicinity of the construction site, it is recommended that you stop this way to better protect the cylinder of the excavator. If you catch up with the work stoppage or the excavator does not work for a long time, this stop can make the cylinder all in the hydraulic oil, which greatly protects the life of the cylinder.
