What key factor influences elevator load capacity?

The design and construction of the elevator cab and equipment are fundamental to determining the elevator's load capacity. Factors such as the materials used, structural integrity, and overall engineering play a critical role in establishing how much weight the elevator can safely convey. Additionally, the size and configuration of the cab itself, including the dimensions and the strength of the components like cables and pulleys, directly contribute to the maximum load capacity.

While speed, control system type, and average number of passengers may affect performance and operation, they do not fundamentally dictate the allowable load capacity of the elevator. The core limit on how much weight an elevator can carry is rooted in its physical design and the robustness of its construction. This is essential for ensuring safety and reliability in operation when transporting people and goods.
