5.1  LIFTING OF JUMPERS & CONNECTORS 

SpecTRON 5 harnesses typically weigh in excess of 30 kg and hence should not be manually 
handled.  Refer to the specific harness drawing for weight and length details. The connectors can be 
safely slung around the locations shown in Figure 4 and Figure 5. The centre of gravity for the 
Connector or Penetrator is usually marked on the outline drawing (supplied in documentation pack) 
but must be verified at low level before commencing any lift. 
For SPO or API flange penetrators, lifting eye mounting holes are provided on the flange at 12 and 6 
o’clock positions.
