Lower crane hook and attach four legged lifting sling. All four legs of sling will be used to lift bridge.
Place hooks on two legs in each jack post bracket. Tip of hook must face outside of bankseat beam.
Pin hooks in with a nose pin and secure with retainer clip.
Operate crane to take the slack from the sling legs. Ensure that cables are not twisted.
Lift bridge slowly and only high enough to permit the roller beam to be slid to one side of site, or back
towards crane if there is sufficient space.
Lower bridge slowly to ground or onto packing if required.
Remove nose pins and hooks from bankseat beam. Remove slings from hook of crane. Move crane
PACKING ENDS OF BRIDGE
It may be necessary to pack the ends of the bridge to achieve a safe bearing on both banks:
If ground conditions are soft.
To level the bridge when it has a cross slope.
To give proper bearing if the bank is a hard prepared (steel or concrete) or natural (rock) abutment.
