What should the pusher's ability be in order to effectively assist scrapers in excavation?

The ability of the pusher to be powerful and heavy enough is crucial for effectively assisting scrapers during excavation tasks. A pusher that possesses this kind of capability ensures that it can generate sufficient force to move materials efficiently and keep pace with the work of the scrapers. Heavy machinery can exert more pressure and traction, which enables it to push larger amounts of earth or debris that scrapers might be handling.

In excavation, the collaboration between the pusher and scraper is vital; a heavyweight pusher works harmoniously with scrapers to maintain an effective workflow without causing delays or requiring frequent repositioning. This synergy in operation enhances overall productivity on-site, allowing for a more effective excavation process that meets project time frames and efficiency standards.

Other characteristics, like being lightweight, small, or quick, may have their advantages in different contexts but do not align with the task of effectively assisting large-scale excavation work where strength and capability are paramount.
