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...
