What is a potential risk associated with improper understanding of gradeability?

Understanding gradeability is crucial in operating hydraulic excavators safely and efficiently. Gradeability refers to the maximum slope or incline a machine can operate effectively without risk of tipping over or losing traction. An improper understanding of this concept can lead to significant operational risks, such as loss of productivity and accidents.

When operators misjudge the gradeability, they may attempt to work on slopes that are too steep for the machine's capability. This can result in the equipment rolling over, causing injury to the operator and nearby personnel, as well as damaging the equipment itself. Such incidents can halt work progress, leading to delays and increased costs.

In contrast, increased fuel efficiency, improved performance in difficult terrains, and better operator comfort do not directly relate to the risks caused by a misunderstanding of gradeability. These aspects are generally influenced by proper operation, equipment selection, and terrain familiarity rather than being risks associated with gradeability comprehension. Therefore, the potential for loss of productivity and accidents is a clear outcome of failing to understand the limitations of the machine on different gradients.
