If due to the angle of the ramp module, the lower jaws connect first. Align the jaws and
the jaw alignment system. Jib forward with the crane so that the module rotates around
the jaws until the dowels are aligned. For further information refer to Chapter 3
Connecting Modules Where the Jaws Contact First.
Align the dowels of the 2nd and 3rd parallel modules.
Extreme caution should be observed when raising the crane while shootbolts are inserted.
Damage to the bridge can occur
Insert the shootbolts to connect the two modules, ensuring that they are locked.
Operate the lower controls on the crane and locate the birds beaks on the bush
resilient mounts. Continue lowering until the module lifting slings just go slack.
Providing the four slings are slack, the guide system on the parallel modules will ensure
correct alignment for pin insertion.
If the pins cannot be inserted, the weight of the module may be taken by the crane until the
pins can be inserted.
Insert the four pins to connect the two parallel modules and secure the pins with the R
clips. Outer pins from the outside in, inner pins from inside out.
Disconnect the tag lines from the 3rd parallel module nearest the tail lift.
On the tail lift pendant, operate the LIFT DOWN switch and lower the tail lift platform
and the pinning operatives clear of the path of the parallel module.
