| If
you are experiencing some of the following situations, it's time to
do an evaluation of the crane to determine if modernization or upgrading
is warranted.
|
Some,
if not all parts are obsolete, delivery times are unacceptable, prices
of spare parts have increased dramatically.
Budgets have to
be constantly updated due to increased component cost. A noticeable
increase in unscheduled shutdowns. Reliability factor is deteriorated
to a level where production cost is increasing beyond the accepted
norm.
More capacity,
operating speed or performance is needed to meet increased production
demands.
Knowingly pushing
the crane beyond it's original rated capacity or production capability.
Allowing less real maintenance time on the crane due to increased
production demands.
Inspection reveals
that the crane is starting to show excessive wear, or it is in noncompliance
with current safety standards or practices.
What is included in an evaluation.
The evaluation is done by a Portal/Rotator design Engineer. After
a thorough inspection of the unit, his evaluation report will do the
following:
- Determines the structural design loads.
-Determines the standard stress calculations based on the maximum
strength and stress range computations.
- A complete operating cycle analysis to determine the current percentage
"used" of the total expected "life" of the structure.
- Recommendations and budget pricing for capacity and efficiency
improvements.
Why upgrade the Portal/Rotator Crane
If the Evaluation reports determine that the structure is sound
with more than half it's life cycle left, then it is much more economical
to do modernization and upgrades on the crane. It can be done in several
stages and spread out over several years.
Portal Crane modernization is totally different from repair. Repair
is a straight forward process of replacing worn parts or components
with new ones of the same design. New technology or improvements
are not incorporated, yet cost keeps escalating.
What are your savings by implementing this program?
The savings could be numerous, depending on what kind of upgrades
are planned.
- Installing stormbrakes could lower the insurance rate and avoid
run aways.
- Changing from AC Wound Rotor motors to DC Motors could lower the
energy consumption on the crane by 40%.
- Prices of the "off the shelf" components are substantially
lower in price.
-Changing from Analog to Digital control and the use of a PLC will
eliminate large control rooms on the girder, lowering the wind sail
area, hence lower energy consumption. Simpler control systems, easier
to learn and maintain.
- Possibility of increased capacity by using "lighter" and
more efficient components
- Higher operating speed, hence more production, lower maintenance
cost.
