The employer is a city administration. Among other things, the employer maintains its own post office or messenger, in which employees with severe disabilities also work.
Disability and functional restriction of employees:
The four employees have back problems. Due to this disease, they can only be used to a limited extent for activities that require frequent carrying and stooping. The GdB
(degree of disability) is 50.
Workplace and duties:
The workplaces are in the post office of the city administration. The employees sort the incoming mail (letters and parcels) for the city administration and frank the outgoing mail.
Upon delivery, the courier lifts the incoming mail from the loading area of his vehicle onto the loading ramp of the post office (Fig. 1). The employees transport the mail from the loading ramp to the sorting room by means of a trolley. There the mail is lifted from the trolley onto the sorting table (picture 2). The mail for the various departments is sorted on the table (Fig. 3). The mail is then placed in the offices' mailboxes or on a shelf (Figs. 4 and 5).
The workflow for the outgoing mail, which is still franked at the beginning, runs in reverse order.
The activities involved frequent lifting of heavy loads in forced postures. In order to avoid an aggravation of the back illness and to reduce the loads, technical aids had to be used, which allow lifting and lowering of loads in an ergonomic working posture.
The employees now transport the incoming mail to the level of the loading ramp using a transport trolley (with mechanical lifting and lowering function) and the existing elevator. From there, the post is transported to the sorting station with the help of the trolley. After sorting, the mail is placed in a circulating rack warehouse (paternoster rack). The mail no longer has to be lifted onto the ramp or sorting table for delivery and sorting. Lifting is eliminated by using the transport aid, which can also be used as a lifting aid (Fig. 6). Due to the possibility of level compensation, the loads only have to be shifted on one level. The use of the circulating shelf eliminates the compulsory postures when mailing, z. B.
bending down and standing on tiptoe.
Assistive devices used:
storage and supply systems
hand operated lifting trucks
