Product Description

High speed dual tower rotating turntable

  • The speed of a one-way wrap while keeping the x-pattern
    With the dual towers/dual carriages, combine the stability and load containment of an X-pattern while achieving the speed of a one-way wrap. While one of the carriages wrap from bottom up, the other carriage wraps from top to bottom; reducing the number of rotations while achieving the same load containment as a conventional dual-way wrap
  • Wrap double-stacked loads individually
    Use one tower and one carriage to wrap the bottom load while the second tower and second carriage wraps the top load separately; obtain two individually wrapped loads simultaneously.
  • More throughput with less revolutions
    Apply the same amount of stretch film with fewer revolutions by using the two film carriages to wrap a single load.
  • Versatility in mind
    Equip one of the carriages with pneumatic roping or banding to increase load containment with a minimum number of rotations; increased efficiency. Also secure the top and bottom portion of the load during the first rotation to improve load stability.
