Hydraulic Excavator (HYEX) 12N Practice Test

The load-bearing capacity of an excavator is determined by considering the machine's total weight, the counterweight, and the center of gravity. This approach ensures a thorough understanding of how these factors interact to influence the stability and lifting ability of the excavator during operation.

The machine's weight contributes to its overall stability. The counterweight plays a crucial role in enhancing this stability, especially when the excavator is lifting heavy loads or reaching out to dig. The center of gravity is essential as it helps determine how loads can be handled without risking tipping or loss of control. When these elements are considered collectively, they provide an accurate measure of the excavator's load-bearing capacity, ensuring safe and efficient operation.

This understanding is vital for operators to make informed decisions while handling materials in various work scenarios. Relying on a comprehensive assessment involving these three aspects allows for greater operational efficiency and helps prevent accidents on the job site.
