A Field Note: We Understand That
This Topic May Not Be In Your Direct Area Of Aerial Fire Truck - For Your Information There Exists (We Hope Helpful) Advice On Making Lift
Bucket Repairs And Upgrades Dependable
It is
interesting that many have found while often
checking into Aerial Fire Truck, there are those who have asked about the following as well:
It is true that you may be able to go to
someone who works with fiberglass in many other
roles, they generally may
not provide the best protection over the long-haul.
For instance, there are both structural needs and electrical insulating properties. Nor will that
company likely have proper liability insurance in case
something does go wrong that may result in legal
actions. And that is not a viable option for
virtually any company. (For
those doing an analysis of Aerial Fire Truck, the comments contained
within this article may be more applicable to to whomever
carries the responsibility for field vehicle
operations.)
Because this
situation involves human life,
this is not something that can be put in the category of
basic mechanical repair or restoration. It is
incumbent upon any operator to approach this situation
with more than simple production goals. So, some of
the special considerations involved in fiberglass repairs
and rebuilds of aerial manlift components
include:
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.
While there are no formal
standards, the lift bucket itself does provide
electrical insulation, so a check of these properties is
an important part of the repair.
The
requirements for correct
mounting of the bucket to
the boom..
If You Are Already
Thinking About Aerial Fire Truck, It Is A Short Step Over To An An Effective Evaluation Of Vendor Capabilities
Given these important
considerations, here is a potentially life-saving
checklist on aerial lift
recondition:
Does the company carry product
liability insurance specifically for
doing aerial lift repair?
Like any
professional, those who
actually do the work, they should have the proper
training and carry the proper certifications. One that is helpful is the CCT certification of
the American Composites Manufacturing Association.
In addition
to the above, points to also review
include:
Aerial man lifts are a very
specialized subset of the fiberglass products industry.
Experience and knowledge of this applicaiton are
critical.
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 literal and figurative potential for dangerous
circuit completion that could effect the operator. (For
situations relating specifically to Aerial Fire Truck, a consultation
with those in your organization who purchased your aerial lift products are a
good idea to gain their perspective.)
Further Than Aerial Fire Truck: Repair Scenarios And The Right Way
To Deal With Them
Look here to see how this might play
out.
Just Doing Your Job May Mean Taking A Bit Of Extra
Time
Here we find that a boom
section shows up to do a general check-over and servicing. A
lower end repair shop may do a basic
visual inspection and little else. However,
when the real uses of the component are considered by
a specialist, its clear they have a mandate that would do
more, including the following items:
Communication with - and gaining permission - from
the entity in authority before commencing
repairs.
A thorough cleaning inside and outside, followed by a
visual inspection 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 (the manufacturer specifications should be consulted prior to the test).
Resurfacing.
Final electrical testing.
Publishing and
notification to the customer of all tests and
servicing done.
Highly protective packaging.
Here Is A Time When More Care Is Needed From The
Very Beginning,
Looking once more at the top
section 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 a full end to end 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. There will be a suitable timeframe for these
materials to setup and reach their full operational
resistance and use. 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 done
after surface finishing or layers are restored. Full
documentation needs to accompany the device back to its
owner/user.
1. A well used fiberglass enclosed operator containment platform comes in.
2. The bucket mount consists of a
number of studs protruding from the bucket wall. One
of the studs is coming out of the side wall.
3.
The bucket probably should not be repaired because of
concerns about the possibility of the bucket later coming
loose from the boom.
When The Basic Bonding Gives Way
A glimpse into this particular
case:
1. A bucket is received for repair. It mounts to the lift arm via a section of
the bucket in which a covering material made of glass
fibers in resins creates a housing for the connecting
hardware.
2. An initial examination of the mounting holes in the ribs reveals that there are cracks in the ribs at the location of the holes.
3. The
bucket probably should not be repaired
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. 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. 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.
