NUMBER
OF CERTIFIED LDE OPERATORS REQUIRED FOR A CRITICAL LIFT
The following is provided for information and to
clarify confusion regarding the "number of certified crane operators
required for a critical lift".
There is no GSFC or NASA requirement that 2 certified
crane operators perform ALL critical lifts. Confusion has been generated
from the fact that an existing NSI Administrative Procedure calls
for 2 certified crane operators for critical lifts performed by NSI.
Most of NSI’s critical lifts in the Bldg 7, 10, 15, 29 complex involve
either payload integration or payload movement (in)to environmental
test facilities.These lifts are usually complex in nature and the
payload is often in a “full-up” condition requiring both a certified
crane operator and a certified “rigger/signalman”.[Note: GSFC crane
operators are certified to not only operate cranes, but they are also
certified to rig the load and provide signaling to the operator.]
For “critical” lifts that are simple in nature, one
certified operator may be sufficient. It is the operator’s decision.
Other personnel may assist the operator in physically attaching lifting
equipment to the load, but it is the operator’s responsibility to
ensure that the load is properly and safely rigged.
