2.2- OPERATION OF THE "JAW IN POSITION ACCEPT" LEVER:
JAWS LOCK POSITION ACCEPTED:
"Jaw in Position Accept Box" placed on the work deck with lever inside for operation to JAW READY FOR OPERATION or JAW
LOCK POSITION ACCEPTED.
When the OPEN-O-LOCK switches on the main control panel are in LOCK position and all lamps for JAW IN
POSITION and LOCK PRESSURE light, the work deck operator inspects the marks on the link joints. When the marks indicate that the jaws are locked he turns the lever to position: "JAW LOCK POSITION ACCEPTED". On the control panel the JAWS LOCKED lamp then comes on.
The Shark Jaw is now ready to hold the load. When the lever is in the
JAW LOCK POSITION ACCEPTED the LOCK-O-OPEN and QUICK RELEASE buttons cannot be operated without first turning the JAW POSITION ACCEPT lever to the JAW READY FOR OPERATION position.
The EMERGENCY RELEASE operates even with the lever in position: "JAW LOCK POSITION ACCEPTED".
Before operating the Shark Jaw the JAW POSITION ACCEPT lever has to be turned to JAW READY FOR OPERATION.
If the pump stops when the jaws are in locked position and JAW LOCK POSITION ACCEPTED the JAWS LOCKED lamp goes out and alarm lamp comes on. Procedure for control of the jaws in locked position then have to be repeated, marks on the link joints inspected and confirmed with operating JAW LOCK POSITION
ACCEPTED.
