Ergonomics in production

A Guide to Ergonomics and Efficiency at Manual Workstations

One of the most important resources in manufacturing, even in the age of automation, is people. Ergonomically designed workstations for workers mean higher performance, work quality, motivation and employee satisfaction, as well as fewer absences due to injuries.

Body height and working height

The optimum working height is based on the body height and the type of activity to be performed. The average optimum working height for average requirements is 1125 mm for sit-down/stand-up workstations.

Work area

The work area should be between 800 mm and 1500 mm high. Working above heart level and bending put employees under disproportionate strain. Dynamic activities (e.g. a combination of standing and sitting) are preferable.

Grab area

Easy access to all the materials required at the workstation must be guaranteed. Torso rotations and shoulder movements, particularly when under exertion should be avoided.

Parts supply

All grab distances should be as short as possible. Grab containers and parts containers placed in direct reach of the employee are therefore ideal.

Vision areas

Unnecessary head and eye movements should be avoided. Maintaining objects at a uniform distance to the worker's eyes eliminates the need for refocusing. Avoid joining points that are not visible to the worker.

Lighting

The right light, adapted to the activity at the workstation, is a basic prerequisite for high efficiency and processing quality. Optimum lighting prevents premature fatigue, improves concentration, and reduces the risk of errors.

Adjustment of work equipment

Correct adjustment of the equipment serves to minimize required movements, thus reducing physical exertion and employee absences.
