Slinging
Application
Load on sling = 1000Kg
Load on sling = 500Kg
Load on sling = 500Kg
1000KG
• SPREADER BAR IS USED AND SLINGS ARE HUNG OFF THIS
• AS SLINGS DO NOT MEET THERE IS NO ANGLE BETWEEN
THEM
• SLINGS ATTACHED TO LOAD SHARE LOAD EQUALLY AND EACH
BEARS 500KG
• SPREADER BAR IS HUNG OFF ANOTHER SLING WHICH BEARS
FULL WEIGHT OF LOAD OR 1000KG (NOTE WE ARE NOT
COUNTING WEIGHT OF SPREADER BAR)
O
90
Load on sling = 700Kg
Load on sling = 700Kg
1000KG
• THIS TIME BOTH SLINGS ARE ATTACHED TO THE CRANE
AND ANGLE BETWEEN THEM IS 90 DEGREES
• AS YOU CAN SEE LOAD ON EACH SLING HAS
INCREASED SUCH THAT EACH SLING NOW BEARS 700KG
O
120
Load 1000Kg
Load 1000Kg
1000KG
• THIS TIME ANGLE BETWEEN THEM HAS INCREASED TO 120
DEGREES
• LOAD ON EACH SLING HAS INCREASED SO THAT EACH NOW
BEARS 1000KG OR FULL WEIGHT OF LOAD
AS WE HAVE JUST SEEN IF ANGLE
BETWEEN INCREASES THEN LOAD
IMPOSED ON SLINGS INCREASE

RULE FOR SLINGING WHEN USING TWO
SLINGS IS:
• ANGLE BETWEEN SLINGS MUST NEVER exceed 90 DEGREES
• EACH SLING MUST BE RATED FOR FULL WEIGHT OF LOAD.
SWL of Assembly 1000Kg
O

1000KG
SAME RULE STANDS FOR FOUR LEGGED SLINGS IN THAT THE
ANGLE BETWEEN SLINGS MUST NOT EXCEED 90 DEGREES. IN
THIS CASE HOWEVER THE BRIDLE ASSEMBLY WILL HAVE TO BE
RATED FOR THE FULL WEIGHT OF THE LOAD.
THIS WILL NORMALLY BE MARKED ON THE RING AT THE TOP
If you choke then half the SWL
Double wrap
to get 360 degree contact
IMPORTANT RULE WHEN USING SLINGS IS:
• IF YOU CHOKE A SLING YOU MUST HALF ITS’ SWL
• WHEN SLINGING TUBULARS YOU MUST ENSURE THEY ARE
DOUBLE WRAPPED. THIS IS TO GET 360 DEGREE CONTACT.
NEVER HIT OR FORCE EYE OF SLING DOWNWARDS WHEN
SLINGING TUBULARS.
SLINGS WILL FIND THEIR OWN BITE
YOU WILL NOT INCREASE THE GRIP BY FORCING EYE DOWN
ALL YOU WILL SUCCEED IN DOING IS INCREASING ANGLE WHICH
AS WE KNOW INCREASES LOAD IMPOSED ON SLING
WHEN SLINGING TUBULARS MAKE SURE SLINGS ARE CHOKED
IN THE SAME DIRECTION.
IF YOU DO NOT, THEN LOAD WILL TWIST.
SLINGS SHOULD BE EQUAL DISTANCE FROM EACH END
ENSURE ANGLE DOES NOT EXCEED 90 DEGREES HOWEVER
THIS IS WHAT HAPPENS IF SLINGS ARE NOT EQUAL
DISTANCES FROM EACH END.
ALWAYS USE TAGLINES
ENSURE LOAD IS CLEAR TO LIFT PRIOR TO SIGNALLING
CRANE OPERATOR.
LOOK OUT FOR DECK BEAMS OR OTHER OBSTRUCTIONS
NEVER MIX DIFFERENT SIZE TUBULARS IN SAME BUNDLE
AS SMALLER SIZE MAY SLIP OUT
PROTECTORS SHOULD ALWAYS BE IN PLACE ON
TUBULARS
BOX END
PROTECTOR
PIN END
PROTECTOR
BASKET HITCH
BASKET HITCH CAN BE USED TO LIFT FRAGILE BOXES AS
SLINGS WILL NOT CRUSH THE LOAD
WHEN USING BASKET HITCH TAKE GREAT CARE LOAD
DOES NOT SLIP
• MAKE SURE THERE ARE NO LOOSE ITEMS ON THE
LOAD PRIOR TO MAKING ANY LIFT
• LOOK ALL ROUND LOAD CAREFULLY
• POSITION TIP OF BOOM DIRECTLY OVER LOAD
• THIS WILL ENSURE LOAD PICKS UP CLEANLY WITHOUT SWINGING
IF TIP OF BOOM IS NOT DIRECTLY OVER LOAD THEN IT MAY
SWING AND HIT PEOPLE OR PLANT CAUSING INJURY OR
DAMAGE.
MAKE SURE SLINGS AND SHACKLES ARE NOT TWISTED
IF YOU LIFT A LOAD WITH TWISTED SLINGS YOU ARE LIKELY
TO CAUSE DAMAGE OR EVEN CAUSE THE EQUIPMENT TO
FAIL DURING THE LIFT
ENSURE LOAD IS LEVEL BEFORE MAKING LIFT
THIS MAY MEAN SECURING LOOSE EQUIPMENT IN HALF
HEIGHTS AND CONTAINERS SO IT WILL NOT MOVE DURING THE
LIFT.
ALL LOADS SHOULD BE LIFTED 2” - 3” ABOVE THE DECK AND
CHECKED TO SEE THEY ARE LEVEL BEFORE CONTINUING WITH
THE LIFT
ALWAYS CHECK INSPECTION PLATE ON CONTAINERS
AND HALF HEIGHTS TO ENSURE TEST DATE STAMP IS
CURRENT.
CONTAINER DOORS MUST BE FIRMLY SECURED
BEFORE MAKING LIFT.
Collect staff tidy inside the container
HALF HEIGHTS MUST NOT HAVE ITEMS OVERHANGING THE
EDGES
THESE MAY HAVE TO BE SLUNG INDIVIDUALLY
Ensure the bottles
will not fall over.
Door to be closed
GAS BOTTLES MUST ALWAYS BE MOVED IN A CERTIFIED BOTTLE
CARRIER.
DO NOT MIX DIFFERENT TYPES OF GAS BOTTLES
(Chemical reaction may happen)
NEVER MOVE A GAS BOTTLE USING SLINGS.
VALVES SHOULD BE TURNED OFF AND VALVE PROTECTOR CAPS
SHOULD BE FITTED
SLING AND
SHACKLE
Mandatory
LIFTING POINT
CERTAIN ITEMS OF PLANT MAY HAVE DEDICATED LIFTING POINTS
FOR USE WITH EYE BOLTS.
ALWAYS USE DEDICATED LIFTING POINTS IF FITTED AS THEY
ARE POSITIONED TO ENSURE STRAIGHT LIFT
BEARINGS AND SHAFTS SHOULD BE PROTECTED FROM
DAMAGE USING WOOD OR RAGS.
IF THERE IS NO DEDICATED LIFTING POINT
THEN YOU WILL HAVE TO CONSIDER
WHERE THE CENTRE OF GRAVITY OF THE
LOAD IS BEFORE YOU POSITIONS THE
SLINGS
REMEMBER THIS MAY NOT BE IN THE
MIDDLE OF THE LOAD
CENTRE OF GRAVITY
BARREL
CARRIER
BARREL
HOOKS
WHERE EVER POSSIBLE BARRELS SHOULD ONLY BE LIFTED
USING DEDICATED BARREL LIFTING EQUIPMENT
WHEN USING PIPE HOOKS MAKE SURE YOUR FINGERS WILL
NOT BE CAUGHT WHEN LOAD IS LIFTED
NEVER ATTACH TAGLINE TO SLING OR HOOK WHEN USING PIPE
HOOKS AS YOU COULD PULL HOOK OUT CAUSING LOAD TO
FALL.
TAGLINE SHOULD BE ATTACHED DIRECTLY TO THE LOAD
SUMMARY
• Never exceed 90 degree angle
• Choked sling = half SWL
• Double wrap tubulars and choke in the
same direction
• Aways fit protectors to tubulars
• Take extra care with pipe hooks
SUMMARY
• Check containers & half heights for current
test date stamp
• Close container doors properly
• Never allow items to overhang half heights
• Sling loads round the centre of gravity
• ALWAYS USE A TAGLINE
General
Safety
ALWAYS THINK
WHAT IF ?
THE SLING BREAKS?
THE LOAD SLIPS?
THE LOAD SWINGS TOWARDS ME?
ADD ANY OTHER WHAT IF’S OF YOUR OWN
FOR ALL THESE YOU SHOULD HAVE A PLAN TO ENSURE YOUR
OWN AND OTHERS SAFETY
ALWAYS HAVE AN ESCAPE ROUTE
DO NOT GET TRAPPED IN SPACES YOU CANNOT GET AWAY
FROM QUICKLY
NEVER TAKE LOADS OVER PERSONNEL
MOVE THE PERSONNEL OR TAKE THE LOAD ROUND THEM
THE SAME APPLIES TO YOURSELF NEVER GO UNDER
SUSPENDED LOADS
BE AWARE OF PINCH POINTS
NEVER WRAP TAGLINE ROUND YOUR HANDS OR BODY
IF ANYTHING HAPPENS YOU MAY NOT BE ABLE TO GET FREE QUICKLY
ENOUGH AND COULD BE BADLY INJURED OR WORSE
TAGLINES SHOULD BE HELD NORMALLY
BE AWARE OF FIXED OBSTACLE SUCH AS STAIRS, VENTS OR
THE DERRICK STRUCTURE ITSELF
SUMMARY
• Ask yourself “WHAT IF ?”
• Have an escape route
• Never walk under loads or allow loads to be
lifted over other personnel
• Watch out for fixed obstacles
• IF IN DOUBT ASK!

SUMMARY
• Can the Crane Op see your signals
• Use a radio if needed
• Speak slowly & clearly
• Establish & confirm radio contact with the
Crane Op
• Be aware of background noise
• Regularly check the battery
