Retractable Structure Features
  • The design of SIS Global Seating's retractable seating system allows maximum seating capacity and an economic solution to seating projects.
  • Demountable rails – slots into sockets mounted on the deck. Allow 50mm inboard.
  • Self-storing rails – open and close with the retractable tiering. Allow 300mm outboard.
  • Each support column is formed from two steel sections for added strength and stability.
  • Under-structure features a double support column for each wheel post providing added strength, stability and long term longevity.
  • Lower guide tracks fully interlock to adjacent tracks to prevent drifting and helps keep alignment.
  • Fully adjustable tiers or rows to ease operation and enhance long term maintenance.  
  • Each moving row is fitted with a steel fabricated parallel guidance system to ease operation and prevent jamming. There are no plastic parts or wires incorporated in this system.
  • Each bottom track is fully interlocked to each adjacent track and cannot separate during operation.
  • Tiers or rows are fitted with a cushioned load transfer skid so that when the seating units are in an open position a solid contact is provided between each row. This eliminates unnecessary noise between tiers when the seating system is only partially loaded with people.
  • Retractable seating structures are designed to operate on flat, smooth level and load bearing floors. A level floor means a FFL of +/- 1mm over 1 metre with a maximum fall of 3mm over the total area. Please contact our Office for further floor loading information.
  • Electric Power Operation: Integral electric power operation can be included to both retractable upholstered benches systems and retractable platforms with integral fold down chairs. Benefits include:
  • One person operation.
  • Seating bank comes out in one block as opposed to separate sections as with manual operations.
  • Less wear and tear on the retractable system structure owing to slow and even opening and closing.
  • EPO can only be operated by the authorised person with the detachable controller, which maintains security.
  • When the seating system is not being moved, the pendant controller is detached to lock the seating system in position. 
  • 10 year guarantee for the support structure.
