- Abstract
Elevators are commonly categorized for passenger or goods use, which determines the structural design of the elevator. In practice, especially in commercial buildings, goods passenger elevators are used to carry both passengers and goods. It is important to understand the loads and stresses caused by the different scenarios to design optimized but safe structures promoting sustainable use of materials. This is especially important with high-rise elevators, where high travel increases the impact of over-dimensioning. The load cases used in component dimensioning are based on the usage type of the elevator and elevator standard requirements. For goods elevators, the standards consider the forklift as the main load-handling device, despite it often being unfeasible due to the space restrictions or building structure. Instead, lighter load-handling devices are often used in commercial buildings. This gap between the real use and standard requirements may lead to over-dimensioning and an unnecessarily high environmental impact due to excessive material usage. This article analyzes the impact of loading on the elevator using light load-handling devices. The elevator design is analyzed using Finite Element Method (FEM) on a car-sling system model. The analysis also covers how the load can be positioned inside the elevator car with commonly used car sizes. The results are compared to the requirements of the elevator standards. Main results include component level stress distribution and displacement results from the car-sling system models and load positioning possibilities considering common car and load sizes. As a conclusion, this article proposes how current elevator standards could be improved based on an analysis of the loadelevator loading scenarios of lighter load-handling devices, concentrating on elevators with higher travel.
