QV forced turns and round belt turns are both Pallet conveying systems Designed for traveling around curves or turns. The main differences are the power transmission method and the applicable pallet size and load range.

The round belt turn relies on a single round belt to provide the turning power for the pallet. However, it has a limited capacity and can only be used for pallets less than 400 mm in size with a maximum load of 20 kg.

On the other hand, the QV forced turn utilizes six timing belts and two motors to generate the turning force. This design provides a more powerful power source, allowing it to accommodate a wider range of pallet sizes, ranging from 160 mm to 640 mm. In addition, it can handle heavier loads compared to round belt turning.

In summary, while both types of turns are used to drive pallets for rotation, timing belt turn conveyors offer a more powerful and versatile solution for a wider range of pallet sizes and higher load weights than round belt turns.
