Traditionally, products were manually packed into boxes of varying sizes while the conveyor belt height remained constant. This meant that when the boxes were large, the products had to be lifted to a high position, placing a significant physical burden on workers and increasing the risk of workplace accidents.

By using Zip Chain Actuator to tilt the end of the conveyor, it is possible to adjust the optimal input position according to the height of the box, significantly reducing the burden on the worker. In addition, the direct lifting and lowering method using a chain makes positioning easier, and stable control is possible compared to commercially available simple pantograph types, leading to improved work efficiency and safety.
