Which of the following examples best represents cargo-handling equipment?

Forklifts represent cargo-handling equipment effectively because their primary function is to lift, move, and manage materials and goods within various environments, such as warehouses and distribution centers. They are specifically designed to facilitate the loading, unloading, and stacking of cargo, making them integral to logistics and supply chain operations.

In contrast, electric cars, while they serve a significant role in transportation, are not typically classified as cargo-handling equipment since they are meant for passenger transport rather than material movement. Charging stations, while important for powering electric vehicles, do not themselves handle cargo. Heavy-duty trucks are indeed used to transport goods but are primarily considered vehicles rather than specialized equipment for managing cargo in confined spaces like warehouses. Therefore, forklifts are the most fitting example of cargo-handling equipment among the choices given.
