Insert the shootbolts to connect the 1st and 2nd parallel modules, ensuring that they
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 1st and 2nd parallel modules, and secure the pins
with the R clips. Outer pins from the outside in, inner pins from inside out.
Disconnect the tag line from the 2nd 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. Make sure the lift
hydraulic cylinders retract to lower the tail lift platform.
