2. SAFETY IN CRANE OPERATION
CASE STUDY # 1
A CRANE HITTING LPG LINE ….
•A crane hit against LPG pipe line while the crane was
marching below the overhead line. The line got bent.
•Negligence of...
•Goal post installed

3. SAFETY IN CRANE OPERATION
CASE STUDY # 2
A HYDRA GOT OVERTURNED…
A hydra (mobile crane) got overturned while
unloading support angles from a trailer. As soon as the
material was lifted from the trailer by 2 feet, a signal
was given by the trailer helper to move the trailer. As
the trailer started to move forward, the support angle
welded to the trailer body got entangled with the
suspended load of the hydra. The load was pulled with
the trailer resulting in the toppling of the hydra.

4. SAFETY IN CRANE OPERATION
CASE STUDY # 3
CRUSHED IN BETWEEN
THE CRANE PLATFORM & COUNTERWEIGHT…
A crane driver and a rigger were to lower a piece of
pipe into a well. After the crane was positioned, the
crane driver assured himself that the rotating cage
was free of people and obstacles and entered the
control cabin. Then, he slewed the jib crane to pick-up
the piece of the pipe. In the mean time, the rigger
climbed up the right-hand outrigger crane support
and leaned over the crane platform to reach the wire

CASE STUDY # 3
CRUSHED IN BETWEEN
THE CRANE PLATFORM & COUNTERWEIGHT…
…..When the driver started slewing the crane, the
rigger was crushed between the crane platform and
the counterweight. The victim was found lying on the
crane platform and taken to hospital, where the
doctors diagnosed a fracture of the pelvis. The victim
died the next day.

6. SAFETY IN CRANE OPERATION
HAZARDS IN CRANE OPERATION
• OVERTURNING
• CONTACT WITH OVERHEAD
ELECTRICAL CABLES, PIPELINES
• CRANES HITTING WITH PERSONS
• SUDDEN RELEASE OF LOAD FROM
CRANE HOIST DRUM WHILE LIFTING
• IGNITION SOURCE FROM EXHAUST IN
HAZARDOUS AREA

7. SAFETY IN CRANE OPERATION
DO NOT
• WALK UNDER LOAD OR PERMIT OTHERS TO
DO SO.
• PARK NEAR EGDES OF PIT
• MOVE CRANE SO THAT IT HITS OVERHED
PIPELINES, ELECTRIC CABLES.
• LEAVE CRANE UNATTENDED WHILE LOAD IS
SUSPENDED.
• PICK-UP LOAD BEYOND ITS CAPACITY

8. SAFETY IN CRANE OPERATION
DO NOT
• EXCEED SPEED BEYONG 20 KM/HR.
• MOVE CRANE WITHOUT COMPETENT
SIGNAL MAN.
• PERMIT PERSONS TO RIDE ON BARE HOOK
OR A LOAD SUSPENDED FROM HOOK
• SLEEP INSIDE CABIN WHILE ON DUTY

9. SAFETY IN CRANE OPERATION
DO
• FAMALERISE YOURSELF WITH THE CRANE
• CHECK SWL (SAFE WORKING LOAD)
• FOLLOW STANDARD CRANE SIGNALS
• USE CORRECT LIFTING TACKLES
• LOWER BOOM TO GROUND LEVEL WHEN
NOT IN USE AS FAR AS POSSIBLE
• GET “ROAD CLOSURE PERMIT” IN CASE
HEAVY CRANE MOVEMENT ON ROAD IS
LIKELY TO CAUSE BLOCKAGE FOR
MOVEMENT OF THE EMRGENCY VEHICLES.

10. SAFETY IN CRANE OPERATION
DO
• ENSURE THAT AT LEAST 3 WINDINGS OF
ROPES AVAILABLE ON ROPE DRUMS.
• HAVE PROPER WARNING SIGNAL LIKE RED
FLAGS & LIGHTS WHILE TRAVELLING.
• MAINTAIN MINIMUM SAFE DISTANCE (6.0 M)
WHILE WORKING OR TRAVELLING NEAR
OVERHEAD CABLES.
•ENSURE ALL SAFETY DEVICES SUCH AS
REVERS HORN, LIMIT SWITCH ARE WORKING
