Our backs are exposed to extreme loads in many jobs, including the skilled trades. Incorrect posture or constant, unhealthy bending in everyday work procedures will result sooner or later in painful disorders. There is therefore an increasing focus on designing workplaces posing a health hazard along more ergonomic lines. In many areas, well-conceived technical measures already minimise the loads for the human body.
Manual strapping of pallets is one of the everyday work procedures that puts a special strain on the back and on the joints. This task entails securing items on a pallet using a plastic strap. To secure the load correctly with two straps for each pallet, the manual method consists in the worker bending over for times and going round the pallet twice. This is a process that can soon become too much for the back and in joints, with workflows in many large companies resulting in the need to strap more than 50 pallets per day. As a result, each work the worker will bend more than 1000 times and walk round the pallet more than 500 times.
A back-friendly alternative consists in ergonomic, semi-automatic strapping systems. With these systems, the worker can strap variously sized items securely and conveniently from a standing position, without having to bend and without having to walk round the pallet.
Ergonomic design of the sealing unit is also important, as well as easy operation of the strap cutter for PP and PET straps. Furthermore, changing the strap rolls must also be a user-friendly procedure that is kind to the back.
In general terms, all control elements must be easily accessible and simple to use. Depending on the particular application, a mobile elevated module for pallets up to three metres in height may also be appropriate.
