High-latitude regions in Europe and North America experience long-term severe cold in winter, greatly affecting machinery startup and operation. Low temperature increases oil viscosity, reduces fluidity and raises operating load; water and oil pipelines are prone to freezing and damage; battery capacity declines sharply, causing difficult startup. Machinery used in cold areas must adopt low-temperature adapted oil to avoid solidification. Preheat equipment fully before operation and avoid cold-machine overload work. Drain accumulated water and protect pipelines after shutdown, and check battery status regularly. Abiding by cold-weather operation standards minimizes low-temperature wear and ensures smooth winter construction.
