Physical effects of new devices for bricklayers.
Bricklaying is a physically demanding job. Bricklayers frequently flex their trunk to pick up bricks and mortar and position these in a wall. The experienced workload is highest working with bricks at 0 to 50 cm from the floor. In this study the effects of 2 devices that have proven to be feasible in practice are evaluated. The 50 cm raise due to the 2 devices is experienced as comfortable, the estimated lumbar compression force was reduced, and observations indicate likewise. It is discussed that the field experiments have many drawbacks. Nevertheless, based on this study in combination with other literature the improvements could be recommended.
