When working at machines and assembly lines, objects are taken from a pallet placed on the one side of the user, prepared and delivered to the opposite side or taken from assembly lines and put on pallets. 
 
Without equipment this might imply lifting both from and to very low heights - meaning strain. A highlifter or a Logiflex could be a good solution. When choosing, it is from an ergonomic view important

• that the user can move freely on the floor in order to avoid twisting of his back and neck
• that the working height is correct all the time in order to avoid bending of the back - when working in too low levels - and to avoid lifting of shoulders and arms - when working in too high levels
• that the distance to the object is as short as possible

If the work implies large and heavy objects, the best way to perform the work is in a standing position. Here a highlifter is the perfect solution. 
 
If the work implies small and light objects and can be performed in a sitting position, a Logiflex is advantageous
