The salary of a construction machine operator can vary significantly based on several factors including experience, location, type of machinery operated, and the specific sector of construction they work in. According to the U.S. Bureau of Labor Statistics (BLS)，in United States:

　　1、Entry-level: Around $35,000 to $45,000 per year.

　　2、Experienced: Around $50,000 to $65,000 per year.

　　3、Highly experienced or specialized operators: $70,000 to $90,000 or more annually, especially in high-demand areas or for operators of complex machinery (like cranes).

　　The lowest 10 percent earned less than $32,830, and the highest 10 percent earned more than $83,790. These figures can be quite different in various parts of the country. For instance, in states like Hawaii, Alaska, and New Jersey, where the cost of living is high, the average salary for construction machine operators can be significantly higher due to the increased cost of living and potentially higher demand for construction work.

　　Moreover, the type of machinery operated can also influence the salary. Operators of more specialized equipment, such as cranes or bulldozers, often earn more than those who operate less specialized machinery. Similarly, those working in the oil and gas extraction sector typically earn higher salaries compared to those in other sectors of construction.

　　Experience also plays a crucial role in determining the salary of a construction machine operator. Entry-level operators often start at lower wages, but as they gain experience and develop a strong track record of safety and efficiency, they can earn raises and potentially move into supervisory roles, which can come with higher salaries.

　　In other regions, Salaries can be significantly lower or higher depending on the country and local cost of living.

　　The salary of a construction machine operator can range widely, but factors such as location, type of machinery operated, and level of experience are significant determinants of pay. For those interested in pursuing this career path, it's beneficial to gain experience and certifications for operating various types of equipment, as this can lead to higher-paying opportunities.
