The box turner is available in four different versions, BT 600, BT 800, BT 2000 and BT 4000 for emptying 600, 800, 2000 and 4000 kg boxes respectively. Operation is by means of a conveniently placed telfer handle. Boxes are emptied by turning them through approx. 135° round their central axes. A restraining sheet reduces the risk of spillage. The BT 800, BT 2000 and BT 4000 can be modified for emptying jumbo sacks instead of boxes
