What describes the operation of two scrapers working together for highway excavation?

The operation of two scrapers working together for highway excavation is referred to as "Push Pull." This method optimizes the efficiency and productivity of the excavation process. In a push-pull configuration, one scraper loads material while the other is positioned behind it to assist in pushing the loaded scraper forward. This teamwork allows for a continuous flow of operation, where one machine maintains momentum while the other is actively engaged in loading, minimizing downtime and maximizing the volume of material moved.

Using this strategy effectively keeps both machines operating in sync, resulting in a quicker excavation process. This method is particularly beneficial in large-scale projects where time and efficiency are critical factors. By utilizing the push-pull technique, operators can maximize the cutting and hauling capabilities of both scrapers, leading to increased output compared to methods that do not harness this cooperative approach.
