Safe Setting Up Of Cable Drums

& Lifting Prior To Cable Pulling

Some safety tips when handling cable drums:

  1. Carry out site specific risk assessment prior to commending cable pulling
  2. Push cable drums into the direction of travel noting “Roll this Way” arrows on flanges
  3. Remove battens or drum protection to ensure nails or tools do not damage the cable
  4. Never pull cable drums with back turned to the direction of travel
  5. Push squarely on the cable drum flanges and be aware for nails in wooden drums
  6. Never allow cable drums to move in an uncontrolled manner
  7. Never position or store a cable drum below an overhead power line

Cable drums should be positioned by the contractor so that the cable pull requirement from drum to the underground trench is straight as possible – cable rollers should be used to guide LV-HV cables into the trench.

When pulling cable into the duct the cable drum should be positioned above the cable duct so that the cable leaves the drum and enters the duct in a smooth curve. The drum shall be rotated by hand during the installation to ensure that the cable does not become tight between the drum and the duct mouth.

Using Cable Jacks

Check that the cable jacks and spindle bars are adequate for the size and weight of the cable drum – the gross weight of the cable drum should  be marked on the drum flange.
