The Belt database contains information on conveyor belts; it can either be generalized data on generic belts, or specific manufacturer data. This data can be selected and modified for the specific conveyor case being evaluated in the Belt Tab on the Main Screen.

The Edit Belt Database screen is accessed from the Data > Belts menu item.

The database that is opened is the specification selected in the Belt Tab (i.e., Fabric, Steel, etc.). The name of this database is displayed in the first row and column of the table.

Some of the supplied belt databases may be designated as read only. The read only databases can be viewed, but a "Read Only" label will appear and the data can not be modified.

Otherwise, the belt database can be edited by:

•The data can be changed in each cell.

•There are a selection of different Belt databases, they can be accessed by the combo-box on the top left corner

•To insert a new belt, click on the "+" button in the upper right corner of the data table, edit values to suit.

•To delete a belt, click on the "-" button in the upper right corner of the data table..

•The changes are saved by depressing the Apply button

When the belt database is changed, there is no return to the previous data; nor is there a way to determine what has been changed. The user should always verify the accuracy of the belt data being used.

The database is automatically arranged in order of increasing belt rating.

For each belt, the following specifications can be entered:

•Rating: [Required; primary selection criteria].

•Number of Plies: [Optional]

•Carcass Material: "S" for steel [Required]

•Carcass Weight: [Required]

•Carcass Gauge: [Optional]

•Modulus of Elasticity: [Required].

•Maximum Belt Width: [Required]. Expressed for combinations of idler angle and weight of bulk material.

•Minimum Belt Width: [Required]. Expressed for each idler angle

•Minimum Pulley Diameters: [Required]. Expressed for range of belt tensions at pulley location. Default tension ranges are 0 to 40% of belt rating, 40 to 60%, 60 to 80%, and greater than 80%.

The material weights used to show Max Belt Width and the belt tensions used to show Min Pulley Diameters can be changed by right-clicking on the appropriate line. However, this changes the selection for all belts in the database! When no belt database is utilized (i.e., "user" belt selection) default values are used and they can not be changed.
