The CSD consists of four brushless motorized E-rollers. A motor for driving the transport rollers, two motors for driving the flat belts and a single motor for the lift. When the lift is lowered, packages can be transferred with the transport rollers. If a package should make a 90-degree turn, it is stopped on the CSD, the lift is raised and the belts are activated allowing the product to move sideways as shown in the image below. In turn, it is also possible to use the CSD in opposite direction, where a package is loaded on the belts, the lift is lowered, and it will continue to transfer over the rollers.
