BELTSTAT is a computer program used in
the design of troughed belt conveyors handling bulk materials.
BELTSTAT can analyze conveyors of any length
and topography having up to ten drive/brake stations,
without restriction as to location. The program can analyze
downhill, regenerative conveyors, and belt widths from
24 to 120 inches. Drives may be conventional head type,
tail, and/or intermediate drives of any combination. Both
acceleration and braking action can be analyzed using
either independently controlled starting/stopping times
or controlled acceleration/braking torque. Starting and
stopping torques may be proportioned as desired among
the multiple drives.
The formulae and calculation methods of BELTSTAT
are based upon the methods and data published by the Conveyor
Equipment Manufacturers Association (CEMA). Selected methods
have been modified or expanded to meet the requirements
of high capacity, high speed overland systems without
limitation of length.
BELTSTAT has been verified against successfully
operating conveyor systems. When used by an engineer familiar
with conveyor design methods, the program functions as
a powerful design tool, providing uniformity, accuracy,
and speed of calculations. The program allows the engineer
to easily explore alternative configurations, such as
alternate counterweight and drive locations, which may
result in a more economical design. BELTSTAT
is designed in a flexible manner for the convenience of
BELTSTAT v7.0 Features
A new BELTSTAT "Quick Start" menu allows
users to quickly and easily analyze a wide variety of
conveyor systems. By inputting some of the most basic
conveyor information users can quickly determine critical
conveyor specifications and components. Eleven of the
most commonly used conveyor geometries are included. They
allow the user to enter up to five flight lengths and
heights. If required, additional flights (up to 500) can
be added using the element table.
Where possible, input parameters are optional. If the
user does not specify these, the program will either use
an appropriate default value or make a selection based
on the known variables.
The new and improved element table gives the designer
a visual image of the conveyor system as it is being built.
It also allows vertical curves and IP points to be dynamically
modified on the fly. This feature makes cut-and-fill optimization
as well as belt liftoff and stress analysis a breeze!
The ability to enter almost any conveyor geometry including
an unlimited number of pulleys and up to 12 drive and
brake stations is just one of the features which sets
BELTSTAT ahead of its competitors.
The result windows give the designer quick access to essential
variables such as belt tensions, safety factors, and plotting
routines. Problem areas are highlighted in red to alert
the engineer of potential design flaws. A graphical representation
of the material loading and maximum lump size is also
For many conveyor systems the vast majority of overall
conveyor design can be accomplished from this single window.
Advanced plotting options allow quick and easy plotting
of conveyor geometry's and tensions. All plots can be
easily customized and cut/pasted into standard applications
such as Microsoft Word or Excel. Also, complete reports
can be easily printed out by the click of a button.
Many of the result windows have graphical pictures to
help the designer visualize the data. As shown here, the
take-up window not only calculates the displaces for various
loading conditions but also shows the thermal travel,
permanent elongation, approximate splice length and other
