If they had used crane mats this accident would not have
happened. |

This will happen every time when the load is to
heavy for the crane. |

Working crane hire at the time driving a 50ton Kato, our client
carries out demolition work of redundant RTG cranes (the rubber
tyred warf cranes that place the boxes after being unloaded) at P&O
ports Fremantle Western Australia. As per their lift study and
procedure signed of and certified by an engineer, the process
involved firstly removing the operators cab, spreader beams and
winch houses, (a total of 5 RTG's where to be disassembled) next
step each of the 6ton wheel assemblies (4 per RTG) are to be removed
and resting the crane to the ground. Step 3, rig and support
1st top gantry beam, estimated weight 11 ton, once cut free it was
to be placed across the bottom bracing sections (photo 2) and fully
welded into place, this in theory replicates the stability it
ensured in it's original position. Once in place and stable,
the process was repeated for the second top gantry beam. Then,
which at the time made perfect sense, one by one rig, support and
cut free the "legs" of the gantry crane, laying them to the ground
and proceed with chopping up the components and trucking them away,
easy .. until the supervisor / director of our client saw a sure
fire way to save a days cranage on each of the 5 RTG's. (Initially a
single 50 ton crane could manage the job, and take around 2 to 3
days per RTG) instead of removing the wheel assemblies first, it was
decided AND approved by the engineer, that this step could be
missed, and the demo would continue as normal. This however
this was not the case .. The first top gantry was cut free and
lowered into position flawlessly, estimated weights were spot on and
all was well. However, in another time saving exercise, the
beam was not fully welded to the bottom bracing, instead 100mm
stitch welds were used. By the way .. something I forgot to
mention, the whole RTG was "precut" and "final cuts" to be made once
supported by the 50 tonner .. in order to once again save on crane
hire. The structure stood solid as a rock in this state for some 75
mins while a boom lift could be repositioned and rigging of the
second top gantry took place. Final cuts were made between
gantry and leg section, again no movement very solid for another 20
mins, whilst making the final cut at the other end of the gantry,
gravity (gotta love that word) took over. The pair of legs,
weighing at 20 ton, 8 ton more than the estimated combined weight,
came crashing to the ground. This alone is an operators worst
nightmare, unfortunately out of sheer bad timing a 10 ton forklift
was traveling past, unauthorized to be within 50 meters of our
operation, and ended up with the cross bracing between the 2 legs,
across the forklift mast, a single meter from the operators cab.
(see photos 4 and 5). Meanwhile, I'm still supporting the top gantry
beam right where it was before the incident, if not slightly more
pale in color. The pair of legs left standing were still apart
of the top gantry by mere mm's of steel. After the top gantry was
re-welded to the remaining legs, the site made safe and
investigated, an 80 ton crane was then ordered in to support the
legs whilst the top gantry was removed safely to the ground, and
then laid the legs to the ground. There were 8 people within
the fall zone of the operation at the time, including myself and the
very very fortunate forklift driver. Reflecting on the
incident, if the legs had fallen inward of the RTG, instead of out
the way they did, the lives of myself, the 2 boilermakers working in
the boom lift and rigger overseeing from the ground would surely
have been lost. Something that didn't hit home for some days
after the incident. I take my position as crane driver very
seriously, this near miss has all but cemented in my head just how
dangerous our line of work can be. Unfortunately just telling
the story doesn't seem to have the same effect on others not
associated directly with cranes in some way. In finishing my story,
the job initially involving a lone 50 ton crane over a 2 week
period, became a 2 week job utilizing 2 100 ton and 1 80 ton mobiles
conducting a 3 crane lift for each disassembly. The safest
way, and perhaps the only way to do it. |

Lucky for the two men in the man basket that they
were able to get out as they were falling from 80 feet above the
ground! |
