Which class of freight elevator allows a fork lift to ride in the car with the load?

The correct choice is Class C1 freight elevators. These elevators are specifically designed to accommodate both the freight and a forklift within the elevator car simultaneously. This feature is critical for efficient loading and unloading procedures, especially in industrial and commercial settings where heavy loads need to be moved. Class C1 elevators typically have larger dimensions and higher weight capacities compared to other classes, making them suitable for this dual function.

In contrast, other classes of freight elevators, such as Class A and Class B, are typically designed for handling only goods or freight, without the ability to safely accommodate a forklift inside the car at the same time. Class C2 elevators, while also for freight, might not have the specific design considerations that allow for a forklift to operate within the car concurrently with a load. The distinction in design and capacity between these classes is essential for ensuring safe operations in various scenarios.
