North Carolina Building Contractor License Practice Exam

Before making a pass, what should a dozer be aligned with?

1. Trencher

2. Tracked backhoe

3. Excavator

4. Scraper

The correct answer is: Tracked backhoe

When preparing for a pass, it is crucial for a dozer to be aligned with a tracked backhoe primarily because of the operational dynamics and safety considerations involved in working with heavy equipment. A tracked backhoe, which is often used for digging and material handling, will have specific lifting and swinging moves that could disrupt a dozer's operation if not aligned properly. This alignment helps ensure that the dozer can operate efficiently without interfering with the backhoe's movements, reducing the risk of accidents. Proper alignment also helps facilitate smoother operations when the dozer might need to push material that the backhoe has excavated. Ensuring that machinery is correctly lined up not only enhances productivity but also promotes a safer work environment by minimizing the chances of equipment collision and allowing both machines to perform their tasks without hindrance. Other equipment types like trenchers, excavators, or scrapers may not necessarily require the same level of alignment as tracked backhoes when making a pass with a dozer, as their operational footprint and interaction are different. The dozer's relationship and alignment with a backhoe are particularly critical due to the backhoe’s movement patterns, which can frequently intersect with the dozer’s intended path of operation.
