Bridge Deck Extension
(optional)
Bridge deck extensions can be attached to 30" (76 cm), 5' (1,5 m), 10' (3 m) and
multi-purpose bridges. Bridge deck extensions are used to extend the width of the work area
from 5' (1,5 m) to 7' 6" (2,3 m), increasing the space available for circulation on the setup.
Bridge deck extensions must be used only for the circulation of workers on the setup
and must not be used as a storage area for material, tools, equipment or any other
load. The weight of each bridge deck extension installed must be taken into account
when calculating the load capacity of a setup. Refer to the Weight of Components table
on p. 14 of the Motorized Unit section.
Installation
1- Remove the plank stop pins and clevis pins from two outriggers.
2- Slide the outriggers in the top outrigger pockets of the bridge and reinstall the clevis
pins to prevent the outriggers from slipping out of the outrigger pockets.
3- Insert the bridge deck extension on the outriggers and push in the extension until it is
snug against the bridge.
4- Install the plank stop pins and push in the outriggers until they are snug against the
extension.
5- Tighten the bolt assemblies of the outrigger pockets both on the deck extension and
the bridge to secure the outriggers in place.
6- Install the appropriate guardrails on the deck extension.
Installation (cont’d)
6- Install the appropriate guardrails on the forward extension.
7- If required, install cross boxes and additional outriggers to plank the inside corner of
the bridge used as an extension. For more information on the use and installation of
cross boxes, refer to p. 113 of the Accessories section.
For more information on the load capacities of forward extensions, refer to p. 99 of the
Load Capacities section.
