Monorail Track

Categories: ,



  • Use: Ideal for the underside of building overhangs, sloped glazing/skylights, all types of atrium glass, domes, and similar applications. Suitable for use with platform, single work cage (platform) or bosun’s chair.
  • Description: Pro-Bel monorail systems are often used to access difficult to reach or otherwise inaccessible exterior or interior glass areas. Typically a Pro-Bel monorail system consists of an aluminum rail section that houses a manual or electrically powered traversing trolley. Monorails are generally used for platform work and monorail supports are typically secured to the building with support hangers at 8′-0” to 10’-0” intervals. Additional supports are required at corner locations and with curved tracks. For a two-person platform, four trolleys are required; two for the primary suspension (platform) and two for the workers’ lifelines.
  • Trolley Types: Pro-Bel monorail systems incorporate various types of trolleys e.g. manual, manual chain drive, motorized, battery-operated, and climbing. Rails, which can be straight or radiused, may be left exposed or concealed in soffit or ceiling spaces. Whatever the application, the platform is slid along the monorail (manual systems).
  • Curved rails: are available with a 90 degree or 45 degree bend or circle configuration and require a 3-0” (915 mm) minimum radius. Typically, workers access monorails via a localized window, hatch, rigging sleeve or ladder. They then suspend their lines from the monorail and return to the first floor or lower level to ground rig their platform. One of the most overlooked items by design professionals is the provision for localized access to the monorail and fall protection for workers while en route.

Note: Rigging sleeves are often used with or as a substitute for monorail where the only option for locating suspension lines or lifelines is through a wall, floor or roof.
