Ergonomic note
The top tray sits at 1.83 m, just above comfortable reach for shorter operators. A 200 mm step platform running along both sides of each trolley is supplied as standard, bringing the top 2 layers into comfortable reach. Trays weigh <7 kg each when loaded — within manual-handling guidance for repetitive work.
