The Vertical Shift Device (VSD) is a high performance transfer device that provides for the transfer of a Supply System Carts (SSC) of an over-under configured PowerStage® system.  Each SSC handles a single pallet at a time and follows the track system in its operation of moving a pallet from one input or output position to any other input or output position on the PowerTrack®.  At the end of each track system the SSC is required to move from one level to a second level which is accomplished by the VSD.

Features:

• High Performance – moves a single SSC cart at high speed between levels of track
• Capacity to move a single fully loaded SSC cart
• Controlled by PASWare® - Standard
• Low Maintenance Drive System – identical to the Vertical Transfer Unit (VTU).
• Low Energy Utilization
• Continuous AC Powered
• Provides for a very compact transportation system layout for those areas that need high throughput in a limited space

Operation:

• While in the home position on the upper or lower track system, an SSC cart is directed by PASWare to travel onto the VSD.
• The VSD then travels rapidly between levels of parallel tracks to reposition the SSC for travel on the other level of the PowerStage system.
• Once in the new home position, PASWare will command the SSC cart to travel off the VSD and move to it’s required next required pickup or deposit destination.
