The following
is our list of maintenance checks. These will provide you with suggested points on your
weighing equipment to have maintained; giving your scale the longest life possible and the greatest return on your investment.
1 Maintain a schedule to
maintain your scale
At least twice a year, be sure your scale technician is schedules to visit your
weighing equipment. A good reminder is to schedule these visits during
the time changes. Just as you change the time on the clock, it's time to service your
scale. Your technician needs to view the scales components to be sure it stays in
working order. Of course, there is always going to be an emergency situation. Those unplanned
days when the scale needs attention are going to occur. Service cannot wait and
Brechbuhler Scales service will not make you wait either, we treat your emergency as if
it were one of our emergencies.
2 Review the past to get
on with the future
As a present client, Brechbuhler Scales uses VPI to
access your scale calibration reports at the touch of a
button. Brechbuhler invests in state of the art technology to quickly review your scale
records. Your past records reveal if there is a history of issues with any area of your
scale. From calibrations, scale readings, any electronic signal issues and the entire
history of your scale is in their hands. The technicians can review these past issues with
the scale operators, discuss how the scale is working to date and review any issues that
could be reoccurring or beginning since the last maintenance check.
3 What you see is what you get
Working from the bottom up, you need to review the foundation first. The site where
your scale is used, day after day, can affect the scale's readings. Foundation issues can
cause poor scale performance, seen in calibration readings, scale weight miscalculations
and scale failure. Take note of any foundation imperfections. From poor flooring
support under floor scales to cracked concrete floors that cause the scale to fall
unbalanced, the area that your scale is used is just as important as the scale itself.
4 Deck, then the walls
Scale decks are fabricated from steel, in various thickness and types. From Stainless
steel to carbon steel, you should inspect the status of the steel during these
maintenance periods. The finish of the deck on a steel scale varies from paint,
galvanization, brushed steel, coal tar and many other coatings. Investigate the entire
deck and make notes of any cracks, rust areas and thinning of the deck material from
wear. Review the support sides of the scale and the locations of the scale and
foundation meeting points. Any debris wedged in between these areas can cause
issues, so a thorough review and cleaning of these areas are important to be free of any
binding or bowing of the scale walls. Many floor scales have adjustable feet to
compensate for uneven surfaces. Be sure to level your scale if necessary.
5 Attachment issues
Many floor scales have accessories that are either are attached or are placed near it.
Ramps, indicator columns, bumpers and other accessories are important to maintain, so
your scale operates properly. Review the location of each accessory, being sure it is in
the correct location of the scale. Ramps should be level, bumpers should not impede
the function of the scale and indicator columns should hold the indicator properly. Be
sure to check for any debris from the industry, as the work environment could present
waste build up around the scale and components.
6 Load up on load cell inspections
Review all of the bolts, anti-rotation pins, and plates surrounding each load cell. Check cable
connections and open spaces around each cell for invasive creatures. Rodents
find areas in and around scales appealing, so thoroughly rid the spaces of anything
foreign in and around the scale. Next, check the cables themselves for cable damage
from rodents, environment or just age. Replace any bad cables and possibly use conduit
to protect the cables themselves.
7 Seal the deal
Invest time in checking the seals of the load cells, the gathering boxes, and the shields of
the home run cable. Built up condensation is the biggest predator with gathering and
junction boxes. Normal warmth from the air that eventually cools, causes the moisture.
Fiberglass materials that many boxes are made with, will help with condensation issues.
Other options to battle this are gaskets and their proper alignment. Be sure the bolts
and closures are correctly used, to avoid distorting the box over time. Heavy water
areas that surround these boxes could merit a complete board replacement. Properly
insure there is no corrosion, moisture being held near the seals or inside the shields.
Replace any moisture ridden home run cables. If any cables leading to the load cells
seem to be holding moisture, create a curve in the cable by bending it just before it
enters the cell, creating a reservoir to hold any errant moisture.
The original manufacturer of the scale should offer peace of mind in the components and
fabrication of your scale. From any installation type, construction and use for the scale, the
manufacturer should be willing and able to provide a complete scope of materials used to
construct and finish your scale, including the warranty behind the product. Brechbuhler Scales
offer B-TEK Scale as their #1 scale product. B-TEK Scales was born from the need of a quality
scale fabricated with superior materials and provide an industry leading warranty.
