Standing assembly line workstation Working in a standing position along an assembly line involves a great deal of walking. Although this in itself is good, there is a tendency for operators to try to work themselves upstream in order to allow time to correct any errors without interfering with the work of operators further down the line. This is a stress situation. Assembly work organization An assembly line which is equipped with ergonomically designed hand tools, and where interactions between tools, work- stations and tasks have been carefully planned, will improve working postures and reduce mechanical load on the operators. An example of this approach in the automotive industry is the general decision to avoid work above shoulder height. Thus, the car Sometimes tools are used in ways the designers never even thought of. 27
2 body is lifted or tilted, or the power tool is suspended in an articulated arm. Rig assembly from above All components to be assembled under the chassis plate, such as the engine drive shaft, exhaust system, wheel suspension, hydraulic pipes and so on, are first assembled in a rig from above. In the automotive industry much effort is put into avoiding tasks that would otherwise require work above shoulder height.
