RESPONSIBILITIES OF RIGGER
  • To Qualify as a slinger / Bansk man, the person
    should
  • be medically and physically fit (have a
    good eye sight, hearing)
  • Have been trained in the safe use of lifting
    equipment.
  • Ability to select and use the lifting

Definition of Rigging
  • Rigging is part of the lifting operation which
    forms the link between the crane and the load.
  • Safe working load (SWL) is the load that can
    safely be lifted provided your lifting equipment
    is in good condition and has three(3) items
    marked on it i.e.
  • S.W.L. or WLL
  • Identification No.
  • Color code
  • If does not have these (3) items marked on it,
    Change
    it for items that do have these (3) items
    marked on it.

Hardware Application
  • When the included angle is greater than 90 degree
    use a shackle to attach the sling legs to the
    hook.
  • Hook Inspection
  • Hook must be removed from service when any of the
    following conditions exist.
  • Cracks, nicks or gouges
  • Twist exceeding 10 from plane of unbent hook.
  • Latch engagement, damage or malfunction.
  • Throat opening exceeding 15.
  • Wear exceeding 10 of original dimension.
  • Damage from heat.
  • Unauthorized repairs.

Safety Precautions
  • Check the sling before use, if any damage don't
    use.
  • Higher elevation rigger should wear safety
    harness.
  • Objects lifting time use tagline to avoid rotate
    the objects.
  • Use proper type of slings, size of slings for the
    objects.

8
Shackle Application
  • Shackle Application
  • Never replace a shackle pin with a bolt. the
    strength of an ordinary bolt is much less than
    that of a shackle pin.
  • Hardware Shackles Inspection
  • Absence of capacity or identifying marks.
  • Bent or distorted pin and/ or body.
  • Nicks, gouges or cracks.
  • Heat or chemical damage.
  • Body spread.
  • Reduction in diameter of pin and/ or body
    greater than 10 .

9
Sling Inspection
  • Rigging equipment shall not be loaded in excess
    of its indicated recommended safe load, and shall
    be inspected prior to each lifting operation. In
    case of wire slings, the working load shall be
    based on the size and load chart, as marking is
    not practical.

10
Inspections shall be carried out for every
lifting device or accessory before use. In
addition, yearly inspection and load test shall
be carried out by a competent inspection
agency. Wire ropes used for slinging will not be
used with sling eye formed by knotting the wire
rope or the use of wire rope bolted clips.
