Ferris Wheel Positioners

  • Most space-efficient, two-station positioner design for parts 3-5 meters long
  • Two design configurations:
    • Slim-Line models with cell footprint only one meter wider than part span
    • Large capacity model with locking pins on each side to stabilize parts in front of robot while heavy parts are hoisted on load station
  • Ergonomic load height and angle of fixture can be varied to ease part loading
  • MotoMount fixture mounting system for quick change and longer life
  • Z-beam center support provides maximum clearance for fixture turning and overhead clearance on operator side for hoist access
  • Three servo-motor control
    • All axes can turn simultaneously while indexing
    • Operator can jog station axis while robot welds
  • Integrated high amperage (1,200/1,600 A) weld ground brushes
  • Hollow tailstocks and optional slip-rings with DeviceNet or Ethernet cabling and air for automated fixturing
