| Abstract: | The aim of this study was to compare materials transfer at a construction site, either by carrying manually or by using an elevator. Data were collected at a construction site by using two methods: continuous automatic collection of data on the use of the elevator, and measuring and observing the transportation of some products when different delivery systems were used. Health and safety risks were at their highest when transporting products manually at construction sites. Risks decrease when vertical (an elevator) and horizontal (a wheeled device) transportation tools are used. A similar improvement as in health and safety risks can be seen in efficiency results: The working time needed with the elevator was 41% of the purely manual handling time. When wheeled devices were used, the transportation time was decreased to 16%. The early use of a permanent elevator succeeded well and its capacity was large enough. The effective use of the elevator and wheeled devices require that pathways are in better condition than normally. |
