High order picking trolley with three floors and folding stairs. The staircase lifts itself without load and when loaded, the staircase with wooden steps stands firmly on the ground and thus blocks the warehouse trolley. The three wooden floors have a beech decor top layer and the top and middle floors have a load capacity of 80 kg. The frame is treated with a powder coating that makes it robust and scratch-resistant. The two braked swivel castors and two fixed castors make the trolley handy and manoeuvrable. The total load capacity is 250 kg.
