Most overseas construction teams believe that working efficiency only depends on equipment performance, ignoring the huge impact of operating habits. The same machinery can have over 30% efficiency gaps between standardized and rough operation, with obvious differences in failure rate and wear speed. Smooth start-stop, uniform-speed operation and gentle lever control reduce impact wear on hydraulic and transmission parts; reasonable working planning avoids idling and invalid walking to improve efficiency. Rough operation reduces construction progress, accelerates component aging and leaves hidden faults. Standardized and refined operation is a zero-cost method to improve project efficiency and extend machinery service life for overseas construction.
