Case Study
Gestaltung eines Arbeitsplatzes für einen Produktionshelfer und seinen Kollegen


The 147 employees of the company produce mass-produced articles for electrical installations, eg. core end adapters, terminals, cables, tubes and hollow rivets.

1. Disabled man:

Disability and functional limitation:

He suffers from heart disease. He can only cope with limited physical stress. His degree of disability is 30 (GdB 30).


He is a trained machine fitter. He has worked for 37 years as a Production Assistant for his employer.

2. Disabled man:

Disability and functional limitation:

He suffers from visual impairment. He has artificial lens implants. In addition, he has spinal disease and a drop splay foot with a malalignment of both big toes. His degree of disability is 30 ( GdB 30).


He has no formal training. He has worked for 24 years as Production Assistant for his employer.

Workplace and duties (actual status):

Both employees are responsible for the cleaning, sorting and control of the manufactured mass-produced articles ( mainly tubes and hollow rivets). The finished mass-produced articles are taken out of the prepared boxes on the floor with large strainers and refilled into angled revolving containers to sieve out the impurities (chips). Articles with adhering oil or coolant lubricant are initially spun in a centrifuge. For this purpose, the articles are tipped manually from cylindrical steel containers into the centrifuge. After the centrifuge process, the centrifuge's drum with holes is removed together with the articles and the content filled into the revolving containers for straining. After completing the sieving process, the small parts are again removed from the revolving containers with the sieves, undergo a random control measure and are refilled into the boxes. At the workplace steel and plastic containers weighing up to 30 kg must be brought several times into each of the work positions. Thus, there is heavy lifting and carrying work which must be partly carried out in a bent body posture. Also the transferring of the articles with the straining spoons requires constant bending at the same time as lifting and carrying weights up to 3kg. The constant measuring and visual control of the articles requires perfect visual acuity.

Workplace and duties (desired status):

To relieve the workers and ensure 100% control of the mass-produced articles the employer wishes to use an automated measuring and sorting machine with high loader. The high loader takes over the transport of the material container and the filling of the stockroom. As the boxes should be put onto a runway and thus transported directly to the high loader, all lifting and carrying work disappears for the workers. From the bin of the high loader the mass-produced articles go with swinging movements into a spiral transporter which takes over the individual ready for storage setup of the articles and the passing on to the rolling measuring equipment. An automated sorting of the articles into different boxes then follows according to the different measurements, which again is placed on a runway for simple removal. At the same time chips and impurities are sorted out by means of the special supply system with swinging transporter, so that a separate work step for this disappears. The centrifuge for removing oil and emulsion is still needed. The setting up of lifting equipment (eg. a rotating column crane ) is needed to ease the filling and refilling procedures. After the new layout of the workplace their duties consist of: - charging the centrifuge - transferring the boxes to the high loader via a runway - setting up the measuring and sorting machines as well as overseeing them - removing the containers via a runway - weighing the containers with the tested mass-produced articles
