CRANE BOOM FAILURE
When a crane boom fails, watch out. As the heavy
piece comes crashing down, lives can be snuffed out and thousands of dollars
worth of property damaged. Crane boom failure can be one of the biggest
disasters on a construction job; yet it can be caused by poor planning on the
simplest lifting job.
LISTEN
CAREFULLY - IT MAY SAVE LIVES
The time to
discuss crane boom failure is before it happens, not afterwards. So pay close
attention to what we're going to discuss today. The suggestions we're going to make could save lives.
TWO MAIN
CAUSES OF BOOM FAILURE
The two
main causes of crane boom failure are overloading and improper loading. Some of
the specific things of which we constantly should be aware are:
Overloading
for length, size, or angle of boom.
Improper
calculation of load weight. Remember
to include the weight of all rigging.
Boom too
high
Sudden
release of load on near-vertical boom.
No boom
stop to keep it from going over backwards.
Two
blocking.
Attempting
side pulls.
Top block
not centered over load.
Swinging
load and not paying attention to the side load on boom.
Load
hitting boom.
Walking or
turning too fast, causing load to swing and twist boom.
Failure to
use tagline or other control on a load.
Chassis not
level, causing side bend in boom.
Not using
outrigger, or outriggers improperly shored.
Not enough
counterweight, tipping the cab house and chassis.
Using boom
with twisted members or braces. Makeshift repairs.
Improper
maintenance.
Poor
brakes. Worn clutch.
Failure to
check boom.
Inexperienced
or careless operation. Chance taking. Short cuts.
