How should we choose the new second-hand excavator Hitachi ZX200-5A

Recently, we have continuously learned that the requirements for mechanical equipment in China are constantly increasing. With the increasingly cold and harsh weather conditions, the air pollution situation has made the environmental protection department focus on excavators, a major emitter. At present, it can be said that most excavators in China use direct injection engines, which cannot meet the domestic standards in terms of fuel consumption and emissions. Especially in China, which is in a highly developed stage, a large number of construction machinery and equipment have caused significant environmental damage and pollution due to a large number of polluting devices during construction. So it will be difficult for old equipment to have living space in the later stage.
