Cross boxes are used to install auxiliary outriggers, as required when planking the inside
corner of a forward extension or the recessed area in a wall. Cross boxes are also used
when doubling outriggers is required.
Installation
1- Remove the clevis pin, hitch pin clip and plank stop pin
(fi g. 8.17, p. 111) from two outriggers.
2- Slide a cross box on the back and the front of each of the
two outriggers. Replace the clevis pin, hitch pin clip and
plank stop pin on each outrigger and tighten the pocket
bolts on both outriggers.

Special planking confi gurations may be required according to job site requirements, to install
planking in areas not covered by standard planking. Only the following three non standard
planking confi gurations are allowed. The following planking confi gurations will require
the use of optional cross boxes and, in some cases, optional 120" (305 cm) outriggers. It is
mandatory to install the cross boxes as close to the bridge outrigger pockets as possible.
Non Standard Planking Confi gurations
3- Slide the cross outriggers through the cross boxes until they
are halfway through.
4- Install a cross box on each cross outrigger and extend each
outrigger in position.
5- Slide auxiliary outriggers through the cross boxes on the
cross outriggers until they are in position. Secure them in
place with a clevis pin and a hitch pin clip. Install a plank
stop pin in each of the auxiliary outriggers.
6- Once the planks are in place, adjust the auxiliary outriggers
until the plank stop pins rest snugly against the planks.
7- Secure the outriggers in place by tightening all the bolts on
the cross boxes to a torque of 30 lb-ft (41 N-m).
