An industrial belt tension tester capable of measuring force from 0-35 lbs (0-15.9 Kg.), and belt tension from 0-560 lbs (0-255 Kg.), on belts to 1" in width.

Recommended for use on 3V-3VX, 5V-5VX and those 8V belts which have force ranges below 35 lbs. Additionally, the instrument can handle A, B, C, and all other single strand belts within the preceding force ranges.

Operation:
Uses the universally accepted method of determining belt tension by depressing the belt 1/64 of an inch per inch of span. This results in an "F" over "T" ratio of 1 to 16. The maximum tension capability of this instrument, therefore, is 16 times 35, or 560 lbs.

1. Measure the length of span between sheave tangent points.
   
2. Set the bottom of the large o-ring at the correct point (on "50" if it is a 50 inch span) and set the top (small o-ring) down against the instrument's flange.
   
3. Depress the instrument downward at the center of the span until the large o-ring at the base of the instrument is in line with the tangent point of the drive. (This may be accomplished with a straight-edge, or a neighboring belt in a multiple belt drive.)
   
4. Read the number of pounds of force indicated by the small o-ring on the plunger rod, then multiply by 16 to determine belt tension.
   

Functions in the same manner as the basic AWI-I, except it services belts to 3" in width, and has a force range of 0-66 lbs (0-30 Kg.), and belt tension range of 0-1056 lbs (0-480 Kg.).

Recommended for use on 3V-3VX belts of 6 strands; 5V-5VX belts of 2 & 3 strands; A & E belts with 2 & 3 strands; and is fully applicable for C belts with 2 strands.

SPECIAL NOTE: The AWI-II can also service multiple single stranded belt drives as well as banded belts.

Operation is the same as the AWI-I above, except for step 4. Because force applied at the tubular handle is distributed equally across two spring-tension units, the pounds-force reading of each o-ring must be added together (i.e., add together the o-ring readings on both plunger rods). Then, to calculate belt tension, multiply by 16.

Functions in the same manner as the basic AWI-I, except it services belts to 5" in width, and has a force range of 0-99 lbs (0-45 Kg.), and belt tension range of 0-1584 lbs (0-720 Kg.).

Recommended for use on 3V-3VX belts through 10 strands; 5V-5VX belts through 6 strands; 8V's through 4 strands; and is fully applicable for A-AX & B-BX belts through 6 strands; C-CX belts through 4 strands; and D belts through 3 strands.

SPECIAL NOTE: The AWI-III can also service multiple single stranded belt drives as well as banded belts.

Operation is the same as the AWI-I above, except for step 4. Because force applied at the tubular handle is distributed equally across three spring-tension units, the pounds-force reading of each o-ring must be added together (i.e., add together the o-ring readings on all three plunger rods). Then, to calculate belt tension, multiply by 16.

Functions in the same manner as the basic AWI-I, except it services belts to 5" in width, and has a force range of 0-165 lbs (0-75 Kg.), and belt tension range of 0-2640 lbs (0-1200 Kg.).

Recommended for use on 3V-3VX belts of 8 strands or more; 5V-5VX belts through 6 strands; 8V belts through 4 strands; and is fully applicable for C-CX belts through 4 strands; and D belts through 3 strands.

SPECIAL NOTE: The AWI-V can also service multiple single stranded belt drives as well as banded belts.

Operation is the same as the AWI-I above, except for step 4. Because force applied at the tubular handle is distributed equally across five spring-tension units, the pounds-force reading of each o-ring must be added together (i.e., add together the o-ring readings on all five plunger rods). Then, to calculate belt tension, multiply by 16.

A wide belt industrial tension tester capable of measuring force from 0-231 lbs (0-105 Kg.), and belt tension from 0-3696 lbs (0-1680 Kg.), on belts to 7" in width. A single setting of the instrument allows an operator to bring belt force/tension to the desired amount.

Recommended for use on 5V-5VX belts and more. Will service 5V-5VX belts through 10 strands, 8V through 6 strands, C-CX through 6 strands, and D belts through 5 strands.

Operation:

1. Study belt manufacturer's manual to determine recommended force and tension ranges for the specific belt being tested.
   
2. Clamp instrument anywhere along the belt, preferably centered, and insure that the 1/8" bar (below the belt) is located between cogs.
   
3. Simultaneously tighten eye-bolts until desired force is indicated on the center unit or desired belt tension shows on the two outside plunger rods.
   
4. Tighten (or loosen) belt until the top of the belt is located halfway up the sighting holes.

NOTE: The WB170 is the only wide belt tension tester on the market which also tests for sheave alignment. Sight diagonally across the top of the belt. If one side is higher or lower than the other, check for proper sheave alignment. Then, repeat the test.

Functions in much the same manner as the basic WB170, except it services belts to 12" in width, and has a force range of 0-297 lbs (0-135 Kg.), and corresponding belt tension range of 0-4752 lbs (0-2160 Kg.).

Operation is the same as the WB170 above.

A wide belt industrial tension tester capable of measuring force from 0-396 lbs (0-180 Kg.), and belt tension from 0-6336 lbs (0-2880 Kg.), on belts to 12" in width. A single setting of the instrument allows an operator to bring belt force/tension to the desired amount.

Recommended for use on 5V-5VX belts and more. Will service 5V-5VX belts through 18 strands, 8V through 11 strands, C-CX through 13 strands, and D belts through 9 strands.

Operation: Follow the steps for the basic WB170 model above, except that the outer two units do not show belt tension.

A wide belt industrial tension tester capable of measuring force from 0-200 lbs (0-90 Kg.), and belt tension from 0-3200 lbs (0-1455 Kg.), on belts to 7½" in width. A single setting of the instrument allows an operator to bring belt force/tension to the desired amount.

Recommended for use on 5V-5VX belts and more. Will service 5V-5VX belts through 10 strands and more, C-CX through 6 strands and more, and D belts through 5 strands and more.

Operation:

1. Measure the belt span (see sketch as shown with AWI-I).
   
2. Place a string on the center - backside of belt and secure.
   
3. Set the small o-rings on the deflection force plungers' scales to zero.
   
4. Position the tension tester squarely on the belt at mid-span with the string centered in the slot. Apply a force on the plunger perpendicular to the belt until the appropriate belt span length is indicated on the slot scale.
   
5. Remove the tension tester and read the force applied from the bottom of the small o-rings on the deflection force scales. If the o-rings on the left and right side are not the same, then check the shaft alignment and make sure the force was applied evenly.
   
6. Read the number of pounds force indicated by the o-ring on one of the outer plunger rods and multiply by 16 to determine the belt tension.
