What are three key components of heavy equipment?

The correct answer highlights critical elements that are fundamental to the operation and functionality of heavy equipment. The engine serves as the powerhouse, converting fuel into mechanical energy, which drives the machine. The hydraulic system is essential for the operation of various attachments and implements, allowing for movement and manipulation of materials. The transmission is responsible for delivering power from the engine to the wheels or tracks, ensuring the equipment can move efficiently and effectively.

These components work in tandem to ensure that heavy equipment can perform its intended tasks, such as lifting, digging, or transporting materials. Understanding these key components is vital for anyone working with or maintaining heavy machinery, as they affect performance, efficiency, and safety.
