The apra-lean assembly station is a mobile and very compact unit for use at assembly workplaces in manufacturing and workshops. The material required for assembly can be arranged systematically and made available within easy reach. Tools can also be easily integrated into the assembly station. The shelves are infinitely adjustable for maximum ergonomics. It is equipped with a grid plate (400 mm or 1500 mm) for the individual attachment of tools, a tool shelf and a supply shelf for consumables (if necessary in open fronted storage bins). The system can be extended with modules (B0 + B1) and accessories.
