Working in collaboration, PERI and Turner Construction designed the Traveling Mono System which has met scheduling and budgetary constraints. We've increased the level of safety for our workers as well as reduced the number of man hours required to set up traditional formwork systems. This system was specifically designed to pour concrete from the ground to the roof giving us ability to maximize our labor force and allow subcontractors to work beneath the system, all while improving on the quality of the finished product.

  • Two-part construction for three different formwork heights
  • Hydraulically operated formwork carriage, movable along the edge beams
  • Temporary support of the edge beams with HD 200 heavy-duty props
  • Comprehensive project solution using formwork and scaffolding from the extensive PERI product portfolio
