|The CATCH 22 faced by
buyers and sellers of belt conveyors was perhaps best expressed by one
vendor who was quoted as saying
"Price is paramount. Price is often
the most obvious thing in a contract, whereas quality of product is
rather more intangible. However, equipment companies cannot sell their
products just because they are cheap - they have to be good as well. The
equipment manufacturers have to achieve a fine balance between cost and
Sellers learn that insufficient quality drives
customers away just as surely as a non-competitive price. And, buyers
too often belatedly learn that excessive maintenance, repair and
business interruption costs far exceed the original price paid.
Resolving this dilemma is not assisted by the millions of different
combinations by which every belt conveyor can be built or the variety of
operating conditions under which they must operate.
WINBELT overcomes these paradox by integrating a
cost data base within an analytical engineering design program. QUALITY
AT LEAST COST evolves logically rather than as an accident tacked on at
another place and time. Requirements of both buyer and seller are
brought together as one.
While the original CREATIVE BELT CONVEYOR DESIGN
& ESTIMATING PROGRAM satisfied a generation of users, pressure
mounted for a Windows version. Development criteria for WINBELT demanded
that there be no additional risk usually associated with a new code.
This need was met by a sharing of code and file system with the legacy
program. As a result users can exchange files between programs and with
minimal editing expect similar results.
- DE-BUGGING - BOOBY TRAPS - MAINTENANCE
Successful engineering design of belt conveyors must look beyond just
meeting immediate performance goals but also to minimizing purchase and
after purchase costs.
The purpose of every belt conveyor is to haul material. Haulage can
also be performed by trains, trucks, barges, screw conveyors, wheel
barrows etc. In most cases the choice is obvious. In other cases AC_HAULPLAN helps select in terms accountants understand. Questions regarding
application and arrangement should always be answered first.
Engineering principles for obtaining a level of belt conveyor
performance are well known. Obviously millions of belt conveyors are
operating worldwide everyday.
from a larger curiosity that questioned, in addition, how best to
maximize profit. This interest came from an awareness that any belt
conveyor can be built in millions of different combinations but also
that failure and maintenance costs go on forever. Maximizing profit must
consider both purchase price and after purchase costs. WINBELT'S
integration of both engineering and cost data within a single program
enables an intelligent seeking of this goal.
After purchase costs must be minimized to maximize users profit.
Analysis of tension under running, acceleration, deceleration and
stopped belt conditions identifies defects while applying tensions in
real time to component design ensures proper selection.
Some belt conveyor defects compare to booby traps that result in huge
immediate business interruption loss. Other defects are more insidious
like an infestation of termites, eating away at profits just as surely.
To understand the scope of these the following list names but a few:
BELT CONVEYOR DEFECTS THAT CAN END IN ABRUPT
CATASTROPHIC LOSS INCLUDE:
- Pulley end plate failure
- Belt/splice failure due to small pulley diameter.
- Belt/splice failure due to insufficient strength.
- Festooning due to loss of belt tension under some condition.
- Breakaway failure.
OTHER DEFECTS LEADING TO EXCESSIVE
MAINTENANCE COSTS INCLUDE:
- Improperly spaced idlers leading to sag/spillage
- Improperly specified idlers leading to premature replacement
MISSED OPPORTUNITIES FOR COST SAVINGS
Best achieving these goals is explained at: AA_WINBELT
- Not extending idler space where tension permits
- Specifying over-size components.
After a prospect is found and a need defined discussions usually turn
Belt conveyors are seldom "off the shelf" and preparing a
price is time consuming. To make efficient use of time it is wise for
sales types to separate the "chaff" from solid prospects.
AB_ESTIMATOR is intended for field use by salesmen. Working with a lap top computer
field salesman working from simple data entry can obtain a price of
sufficient accuracy to qualify prospect's interest. Based on that
expression of interest a decision can be made on how best to proceed.
If a project requires feasibility analysis the price determined by AB_ESTIMATOR is sufficiently accurate to meet this requirement without further
expenditure of time while still meeting clients immediate need.
Haulage feasibility studies are tedious and time consuming. It is in
the interest of both buyer and seller to expedite this. AC_HAULPLAN reduces months of work to just a few hours or less and in the process
can examine more alternatives. Expediting decisions can favorably reward
the astute vendor who has stepped forward with this assistance.
Having qualified the prospect AA_WINBELT provides engineering and, with proper price multipliers entered,
quotation quality price for the components and estimates for the
installed belt conveyor.
Structural steel is often the "the tail that wags the dog"
in a belt conveyor proposal. To assist at finalizing these numbers WINBELT provides two programs that assist at projecting these prices: AD_TRUSS
