Bucket Repairs And Upgrades A More Cost Effective But Safe
Item
Introduction: While you may not have thought about it
much in your search
for Aerial Lift Accident, this alternate topic has triggered
questions by many into other related
areas of inquiry. Here we detail one of these:
Since there
are times when these devices are in extremely high
demand, a
temptation to make the repair as cheaply as
possible is always there. That choice can have tragic consequences.
There are many ways to cosmetically repair the bucket
that leave the lift truck owner open to potential
catastrophes. For instance, physical repairs must
take into account the underlying structure. If damage has
been done there and is merely patched over (or dealt
with in any less than structurally responsible manner)
by a repair source such as a body shop, mechanical/engine
repair or even a custom molder, then the bucket could
give way at a critical time it is being loaded, often
high above the ground. There can be breaks in the electrical insulating
properties of the bucket that are created during a
surface only type of repair. While this may or may not seem important to those
who are currently investigating Aerial Lift Accident, we suggest you forward it to those
responsible.
Looking at the situation , these are some of the
issues:
What the official
specifications are for making sure the upper boom is
dielectrically separated from the lower boom, and how
this separation can be compromised.
The level of tension and damage the insulators for the upper and lower boom can safely withstand without compromising their insulation properties.
The real insulating
capabilities provided by the fiberglass bucket
itself, although the bucket is not officially
recognized for insulating capability by ANSI
A92.2.
The
requirements for structurally sound
mounting of the bucket to
the boom..
You Have Considered Aerial Lift Accident,
So Now How Do You Restore A Lift?
So what capabilities are needed for the
entity that can safely complete a bucket truck lift
repair?
Is there any way of verifying that they currently
have the full level and type of liability insurance that is specifically
underwritten for the after
repair problems that can occur with regard to bucket
truck lift repair area?
Are the
personnel technically competent for this type of work,
carrying the appropriate certifications
such as those offered by the ACMA?
In addition
to the above:
The components in aerial man lift units must perform
as life preserving conveyances with high levels of
criticality, often beyond other uses for fiberglass. Does
this supplier understand this unusual way of applying
fiberglass?
In addition to maintaining
physical integrity, after a repair has been made, a final
electrical insulation test should be performed to ensure
that the refurbishment process has not also created a potential for dangerous
circuit completion that could effect the operator. (For
situations relating specifically to Aerial Lift Accident, a consultation
with those who purchased your aerial lift products are a
good idea to gain their perspective.)
Further Than Aerial Lift Accident: Repair Scenarios And The Right Way
To Deal With Them
We have listed what you
might say are a bit sanitized versions of encounters from
our own experience. A competent process would
embody most of the illustrations we have
included.
Sometimes You Have
To Look A Bit Deeper Because ,
There Is Often Not Much That Is Apparent
Your local fiberglass rehab
supplier is contacted. Through either shipping or
pickup, they are in possession of an
upper boom in fairly good condition for surface
refinishing and rehabilitation. Here are the
steps:
1. The first thing that should be done is
to visually examine the boom for any evidence
of damage. Any such evidence should be compared with
boom damage criteria shown in the OEM manual.
2. If the boom is dirty inside, the shop should
ask to pressure wash
the inside. After cleaning, the boom should
then be dielectrically tested to make sure that it is
still dielectrically sound. If there is a dielectric
problem, the boom should be analyzed with a conductivity
tester to identify the problem. .
3. If there are no additional problems, the boom
should be cosmetically repaired and refinished as needed.
4. Then, the boom should be dielectrically tested
again and structurally tested. If it passes, the boom should be waxed ,
and shipped back to the owner. The final phase is
creating some type of secure package in which it is
placed .
Here Is A Time When More Care Is Needed From The
Very Beginning,
The top most section of a telescoping lift arm that has clearly sustained some damage is brought in.
1. The cracks should be reviewed using the repair manual guidelines of the manufacturer. The repairer
should estimate it so that the owner
can compare that to the cost of a new boom.
2. If approved, the repair company
should complete the structural repairs using the proper reinforcement and resin, let the repairs cure, then do a structural test on the boom checking for any problems.
3. The boom should then be cosmetically
refinished and dielectrically tested and returned to
the owner.
When It Is Not Safe To
Even Consider Repair
There are not a lot of backup
systems with a bucket style lift mechanism, and that
goes double with the
attachment of the boom to the bucket itself. There are
various ways that this main support can be
accomplished. In this case:
The main attachment
was accomplished through threaded rods that are in
effect integrated into the side of the bucket.
It was clear
that there were fissures in the actual fiberglass
that surrounded and supported
these mounting rods.
Without even checking
further it is apparent that no amount of
reinforcement would make for a safe operating condition for the
operator.
Structural
Issues
While the
owner ultimately makes the call as to repair, they
depend on expert repair depots to
provide the advice on how successful the operation may
be. In effect the risk management falls on whoever
at the customer is managing this function. So here is
a piece of advice we gave.
Buckets can be
attached by creating an assembly out of the actual
fiberglass, formed from thick, redundant layers of
resin and the glass strands.
Gaps, damage
or stress lines
can form in these attachment
points.
Under
this scenario, it is pretty difficult to make sure
that the deterioration can be turned around enough to ensure the operator of the the equipment will not be
compromised.
A competent facility would recommend replacement.
Where It Looks Worse
Than It Is, But It Really May Not Be That
Bad
Now that we have created
circumstances where critical repairs should be made
and/or where it is beyond being reasonable to move into
that direction at all, a more normal state is when field
use has not yet pushed the item out of its service
range. Recycling in effect is a good potential for
such occurrences, particularly if the ownership is
willing to trade functional for cosmetic differences and
allow the vendor who is tasked to offer trade-offs
between these poles. It is very likely that this apparatus
can be returned to many years of active service.
Communication with whomever sent the device in is
appropriate - basically to ascertain the level of
work that should be done. In this
case, providing levels of pricing for each approach
action, structural only or structural plus
cosmetic, is the appropriate response.
