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.
CAREFULLY - IT MAY SAVE LIVES

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.
CAUSES OF BOOM FAILURE
main causes of crane boom failure are overloading and improper loading. Some of
the specific things of which we constantly should be aware are:
for length, size, or angle of boom.
calculation of load weight. Remember
to include the weight of all rigging.
release of load on near-vertical boom.
stop to keep it from going over backwards.
not centered over load.
load and not paying attention to the side load on boom.
turning too fast, causing load to swing and twist boom.
use tagline or other control on a load.
level, causing side bend in boom.
outrigger, or outriggers improperly shored.
counterweight, tipping the cab house and chassis.
with twisted members or braces. Makeshift repairs.
brakes. Worn clutch.
or careless operation. Chance taking. Short cuts.
