Here Are The Essentials On Lift
Truck Bucket Reconditioning/Replacement And Accessory
Selection As A Companion To
Telescopic Boom Lifts
Introduction: While you may not have thought about it
much (or even really considered it) in your search
for Telescopic Boom Lifts, this complimentary or
supporting issue of concern has generated viable explorations by many into other
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 fast as
possible is always there. There are many ways to cosmetically repair the bucket
that leave the lift truck owner open to potential
catastrophes. There can be breaks in the electrical insulating
properties of the bucket that are created during type of repair. While this may or may not seem important to those
who are currently investigating Telescopic Boom Lifts, we suggest you forward it to those
responsible. Titles may include
safety officer, maintenance and repair, field operations,
training, general management or even the legal
department.
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.
How strength must be retained
in the fiberglass boom insulators, no matter how much
working abuse and loads they are subjected
to.
The real insulating
capabilities provided by the fiberglass bucket
itself, although the bucket is not officially
recognized for insulating capability by ANSI
A92.2.
A certain component for
preservation of human life is the 100% dependable linkage of the
bucket and the boom.
More Than Telescopic Boom Lifts: The Critical Assessment Of The
Abilities Of A Repair Facility For The Most Important Fixup
You'll Ever Do
Given these important
considerations, here is a potentially life-saving
checklist on aerial lift
troubleshooting:
Can they prove that they
have liability insurance that is specifically
underwritten for the bucket
truck lift repair area?
Are any of its people certified by the American
Composites Manufacturing Association as Certified
Composites Technicians?
There are other steps that
should be taken, if one was serious about this potential
problem.:
Aerial man lifts are a very
specialized subset of the fiberglass products industry.
Experience and knowledge of this applicaiton are
critical.
How does a customer know
if the insulating properties of bucket and boom have been
maintained during repair? By using an approved testing
device. In this situation it becomes the next
evaluation point to check. (Again, we realize your direct interest is in Telescopic Boom Lifts .
Please consult manufacturer specs to determine
applicability.)

out.
Just Doing Your Job May Mean Taking A Bit Of Extra
Time
Here we find that a boom
section shows up with little or no instruction from the owner except - to do a general check-over and servicing. A
lower end repair shop may do no more than a basic
visual inspection and little else. However,
one that
is familiar with the gravity of the need would do
more, including the following items:
Communication with - and gaining permission - from
the entity in authority prior to any charges being incurred.
A thorough cleaning inside and outside, followed by a
visual inspection with instruments that can help to
view into the inner cavity of the boom itself.
Initial dielectric testing to determine unwanted
continuity for any potential grounding that may
otherwise occur because of damage.
Load or stress testing, often at multiples of the rated capacity.
Resurfacing and additions of protective coatings.
Final electrical testing.
Publishing and
notification to the customer of all tests and
servicing done.
Highly protective packaging.
Looking once more at the uppermost member of the support boom. It has fractures that have been flagged in the field and also are confirmed by an initial visual inspection. There
is usually a cosmetic and visual coating on the boom
itself. This protective layer should be
stripped off and inspection made
both on the outside, and also on the hollow
inner core of the boom itself. Next determine if it can be repaired and the boom
restored to full and safe operation. This is done by
consulting what the manufacturer has declared proper, and
also comparing the damage to the capabilities of the
repair materials. These typically include physical
reinforcement, using similar OEM products and suitable
bonding materials which are impregnated into the repair
base. At that point in time, a full
mechanical stress/tension test needs to be performed at
over the rated loading for the boom section.
Appropriate electrical testing would follow the same
pattern, but this would most likely be done
after surface finishing or layers are restored. Full
documentation needs to accompany the device back to its
owner/user.
Using An Instructive
Example To Illustrate The Dangers Of Proceeding With
Improper Repair And Returning A Component To Full Field
Use
When there is
a potentially
non-repairable defect, it is tempting to fix
it. For instance, where the actual bucket mounting bolts have pulled away from the laminations in the containment bucket itself. This is put back in shape by recompressing the mounting into the fiberglass laminations. Repair in this
situation is not likely to produce a safe, dependable
platform. These connections are primary and must be an integrated
part of the platform integrity. The most responsible action in this
casewould be to reject the item for repair and ask
that it be replaced.
When The Basic Bonding Gives Way
Another
situation is when the
enclosed platform that holds the operator is formed into reinforced arches
that in turn
are used to connect the boom arm. When these mounts are cracked or badly worn, it
can compromise the actual boom mounting assembly. If
this is the case, it is more than a concern for the
safety conscious operator. While there are repair
techniques that can be used, the recommendation to the owner would be for replacement rather than remanufacture.
A Bucket Or
Similar Item For Repair That Has Cosmetic Damage And
Yet Remains Remarkably Sound Otherwise
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. The key question is
whether it is mainly restoring the holding capability of
the bucket or in addition whether surfaces need to be put
back to near OEM levels of feel and look. In this
case, providing levels of pricing for each approach
action, structural only or structural plus
cosmetic, is the appropriate response.
