OUTRIGGER BEAM SYSTEMS
DescriptionPro-Bel aluminum or steel outriggerbeams, used singularly or in pairs, pro-vide a practical means of suspendingbosun’s chairs, single work cages or plat-forms.
Each worker’s lifeline must be secured toa separate independent safety anchor.
OUTRIGGER BEAM TYPESDepending on factors such as roofspace, roof loads, parapet height orstrength, roof type or other factors, non-permanent “conventional” outriggerbeams with counterweights normallybrought to the site by the suspendedmaintenance contractor may not be suit-able. In this case Pro-Bel manufacturesand offers a range of engineered, struc-turally secured outrigger beam systemsdesigned to suit all roof conditions.
Portable Outrigger Beams: these beamsare designed and dedicated to a specificbuilding or roof area and capable of beingmoved from work location to work loca-tion within the dedicated area. They areattached (pinned) to permanently in-stalled bases or anchors during mainte-nance operations and placed in storagewhen not in use.
Fixed Outrigger Beams: these beams arepermanently installed equipment and aredesigned to remain at a fixed location.Typically for long spans over 10’-0” (3 m).
UseSuitable for roofs with sufficient inboarddistance and are typically for groundrigged equipment.
Long span beams are ideal for accessingdifficult-to-reach areas e.g. beyond slop-ed roofs, terraces, and sunscreens. Addi-tional inboard roof distance is required.
Roof design conditions with minimalinboard distance or lack of structural sup-ports may dictate the use of a davit sys-tem at roof edge or parapet.
Refer to Pro-Bel Outrigger Beam Sys-tems literature for more detailedinformation.
Pro-Bel portable swivel-type outrigger beam with dolly is designed to suit a specific roofarea and can be relocated within the dedicated work zone. Portable systems must bepinned to permanently installed bases or anchors during maintenance operations.
Pro-Bel fixed outrigger beam systems are designed to remain in place. Sliding beam, asshown above is ideal where inboard roof space is not restricted. Sliding beams typicallyspan over 10’- 0” (3 m) beyond the fulcrum and are available in aluminum or steel.
