Requirements to Operate a Crane

• Currently Trained Certified by Olympic Steel
• Not under the influence of Drugs, Alcohol or
  Medications

4
Pre Shift inspection

• Operate all of the controls to insure they
  operate correctly
• Inspect the following from the floor

6
What to look for

• Drum
• Cables rapping straight, not overlapping and not

7
Documentation of Inspection

• Check off inspection sheet
• Make notes of problems
• Inform your Supervisor of any problems noted

• If crane is deemed unsafe, take it out of service
  do not use it until it is repaired

General Crane Safety

• Conduct inspections at least at the beginning of
  shift or if it is the first time you are using
  that day.
• If you are unfamiliar how to use a certain
  lifting device get instructions from your
  supervisor before using.
• Keep yourself and others out of pinch points, out
  from under loads and out of potential impact
  areas.
• Wear gloves if you must touch the load

9
General Crane Safety

• Conduct a Quick inspection of the crane all
  lifting devices before each use
• Insure the Crane Lifting Device can handle the
  weight of the load
• Remember 1 TON 2000 lbs.
• Never conduct a side pull
• Never Shock or jerk a load
• Identify other personnel trip hazards in the
  area you are operating in

10
C-Hooks

• Always position throat of C-hook over center of
  coil
• Always stand to front or rear of the closed side
  of the c-hook
• Never allow anyone to stand in front of, behind
  or next to the open side of the coil.
• Never place the coil on the banding clips.

11
Sheet Lifters

• Never try to make a lift on the widest part of
  the steel
• Insure the teeth are totally under the steel
  before lifting the load
• Insure the steel is straight in the sheet lifter
  and not angled
• Never allow anyone to stand in front or behind
  the sheet lifter
• Never place hands under a load to move cribbing

Magnets

• Always store magnet on a clean area
• Do not bang magnet around
• Stay out of pinch points under load
• 6 Factors that affect lifts with magnets
• Charge of Magnet
• Surface area of magnet that is making contact
  with steel, must be at least 65 or greater
• How clean magnet is
• How clean steel is
• Thickness of steel
• Weight of object

15
Chains

• Do not expose to sudden shock
• Store on the rack or wall to prevent unnecessary
  damage
• One damaged link could cause the chain to break.
  Inspect at least the first time you use it every
  shift for
• elongated links
• bent links
• worn links
• cracks
• crushed links

16
Pallet Lifters

• Inspect pallet before use to insure it is in good
  shape
• Insure material is stable on pallet and will not
  spill
• Keep all personnel away from all sides when off
  the ground
• Lift only as high as needed to clear the tallest
  obstacle.

• Always give yourself and others several feet in
  case the plate shifts on the dogs
• Store dogs chains off the floor

18
Spreader Beams

• Give yourself and others a lot of of room with
  this device
• Insure completely under plate and balanced
• Stand back lift an inch off ground check to
  see if balanced
• If not balanced set down and lift again

19
Review

• All operators must be certified
• Only use lifting devises you are familiar with
  and trained to use
• Document the pre-shift inspection
• Conduct a quick inspection of the crane lifting
  devices before every use
• Keep yourself other out of danger areas(pinch
  point, possible impact areas)
